(0.4) Special Report on OS/2 Warp

"It's time..." -- Leonard Nimoy

On October 11, 1994, IBM announced its boldest entry into the burgeoning home
and small office software market, OS/2 Warp Version 3. Widespread on-the-shelf
availability of OS/2 Warp occurred on November 4th in the United States.

OS/2 Warp is the latest in a line of releases which have achieved broad
acceptance in corporations around the world (and in many other segments of the
software market).  Over eight million people use OS/2 today, and that number
just keeps growing.  However, previous releases were criticized for being
difficult to install, short on the list of included device drivers, consuming
too much memory, an "industrial" appearance rather than a flashy one, and
having bundled applications which were not appealing.  In short, it was
criticized for not appealing strongly enough to home and small business users,
many of whom are struggling with an aging 16-bit Windows environment and who
are craving for something better.

Nonetheless, OS/2 has always been praised for its reliability, superior
compatibility with existing DOS and Windows applications, true preemptive
multitasking systemwide, and a state-of-the-art 32-bit programming environment
for friendlier and more powerful applications.  Features which have made it
the most popular 32-bit software in the world and which have earned it over 50
major awards, including PC Magazine's Editor's Choice and Infoworld's Product
of the Year.

IBM has, quite simply, "consumerized" OS/2 in creating OS/2 Warp.  OS/2 Warp
is the fastest, friendliest, and most powerful version of OS/2 yet.  And, in
concentrating on improving OS/2 in areas which matter most to home and small
business users, IBM has ended up making OS/2 better for everyone, especially
for current Windows users.

Here is but a sampling of the features and improvements you'll find in OS/2

o Lower memory requirements.  OS/2 Warp really runs on a PC with as little as
4 MB of memory, and it races on a system with 8 MB.  But no matter how much
memory your PC has, OS/2 Warp now gives more memory to applications.  That
means speed, and that means you finish your work faster.  And, naturally,
since this is OS/2, memory management woes are a thing of the distant past.
Get over 600K of free base memory in your DOS sessions, even after all your
drivers are loaded.  (Get over 700K free if your DOS application requires no
more than CGA graphics!)

o Enhanced Workplace Shell.  OS/2's Workplace Shell has been praised for its
ease-of-use for quite some time, but there are still major improvements to it
in OS/2 Warp.  A new LaunchPad lets you drag and drop the programs, folders,
and other objects you use most frequently to a quick-access button bar.  The
LaunchPad is fully customizable, and it's always ready when you need it.  The
Workplace Shell now has palette awareness (so background bitmaps always look
their best), "Comet Cursor" so you won't lose track of your mouse pointer,
customizable mouse pointers, Pickup and Drop menus (so you won't have to open,
shift, and resize windows before you drag and drop), automatic closing of
parent folders (if desired) and an Open Parent menu option, animated icons (so
that folders actually pop open when you double click), backup and recovery of
your desktop (so you never lose your setup), an Undo Arrange option (if you
accidently rearrange your desktop when you didn't mean to), opaque background
icon text (so they really stand out against a complex background bitmap), drag
and drop setting of background bitmaps, and much more.  And the default color
scheme?  Dull, boring gray is gone, replaced with a soothing teal background
and much more colorful icons.  Plus it's easier than ever to find objects,
thanks to the much simplified Find window (just a single click away from the

o Performance improvements.  With the addition of new 32-bit code, the
Workplace Shell is now much speedier.  Folders pop open and close in record
time.  Shutdown races for the finish.  Printing benefits from a new 32-bit
engine, so more complex images are processed more swiftly.  And printing no
longer requires that you dedicate a precious interrupt (IRQ 7) to the task,
very convenient for AT bus systems.  OS/2 Warp can handle the hard disk much
faster, particularly when formatting and checking (CHKDSK) the disk,
particularly with the High Performance File System (HPFS).  OS/2 Warp starts
up faster (and with many fewer, if any, distracting device driver messages).
Most importantly, perhaps, the "industrial" OS/2 logo you saw in previous
releases has been replaced with a sleek new OS/2 Warp logo (which you can even
use as a background bitmap).

o Installation.  Installation has been a sore point for many first-time OS/2
users.  The problem wasn't so much that their hardware devices weren't
supported, it was that available device drivers were not included with OS/2.
OS/2 Warp changes that, with generous built-in support for both older and
newer video cards, CD-ROM drives (even non-SCSI models, including IDE drives),
sound cards, TV tuner cards, video capture cards, mice, printers, PCMCIA, and
SCSI cards.  You won't have to go fishing for OS/2 device drivers nearly as
often (if at all).  Plus there's now a one-button "Easy Install" option.  OS/2
Warp will automatically interrogate your PC to find out what hardware is
installed then put in the correct device drivers.  Without asking dozens of
questions.  Multimedia support is now part of the main installation -- no
tacked-on procedure.  Selective Uninstall lets you deselect and remove those
features you thought you might want but really didn't need -- no more poking
around your \OS2 directory, hoping you delete the right files.

o BonusPak.  Gone are most of the "applets" found in previous releases of OS/2
(although you may use them from your prior release of OS/2).  Instead, IBM has
spent a considerable amount of time collecting true 32-bit OS/2 applications
which are both useful and which demonstrate the power of OS/2 Warp.  About a
dozen applications are included in the BonusPak, accompanied by a friendly
installation program (which, if you have a sound card, will even play music).
The BonusPak applications include:

- System Information Tool.  Do you remember how large your hard disk is?  How
many colors your video card is displaying with OS/2 Warp?  How sensitive your
mouse is?  How much memory you have installed?  Visit the System Information
Tool to find out the answers to these questions and more.  Part of the
high-end IBM Netfinity for OS/2 hardware management product, it's now yours
free of charge in OS/2 Warp.  There's even a feature to list all the device
drivers in your OS/2 Warp system, along with version dates.

- Internet Connection.  Certainly the highlight of the entire BonusPak, this
set of applications (including Gopher, Ultimedia Mail, Telnet, ftp, and so on)
gets you connected to the entire Internet using a dial-up SLIP connection.
Registration on the IBM Global Network is a simple button click, and you don't
have to memorize arcane commands or learn about IP addresses.  You can also
use your own Internet provider if you do not wish to use IBM's.  However, you
get three free hours of connect time on the IBM Global Network with every copy
of OS/2 Warp.  Send and receive Internet mail (even mail with sound and video
attachments), explore the World Wide Web with the IBM Web Explorer, browse
weather maps and online library catalogs with Gopher, and even chat with other
OS/2 Warp and Internet users in the Internet's newsgroups.  And, only with
OS/2 Warp, you don't have to wait while you are downloading a file or complex
Web document -- go do something else.  OS/2 Warp delivers real multitasking,
so you never have to wait.

- Person to Person.  For desktop videoconferencing and collaboration on
projects, or for a new way of communicating that's just plain fun, IBM's
Person to Person is included with the BonusPak.  Person to Person gives you a
Chalkboard which lets you share bitmaps (including copies of spreadsheets,
documents, and other windows on your desktop) with other Person to Person
users across a network, by modem, or even over the Internet Connection.  What
you draw or put in your Chalkboard is immediately sent to all the other people
in your Person to Person "conference call."  You can also share the contents
of your Clipboard and carry on a live conversation by keyboard.  With
appropriate hardware, you can also transmit live video.  Save plane fare and
work on projects with your friends and colleagues without actually being in
the same room.

- Compuserve Information Manager.  Access Compuserve in grand style.  There's
even an icon for the OS/2 forums, so you can get speedy answers to your OS/2
Warp questions.

- HyperAccess.  Dial up BBSes, Dow Jones, MCI Mail, BIX, GEnie, and many other
online services with this richly featured communications software.  It even
includes dialing directories and ZModem.  And, remember, downloading or
uploading a file under OS/2 Warp doesn't mean you have to wait to do something

- Faxworks.  Send and receive faxes of unlimited length using the most popular
fax software for OS/2, Faxworks.  You can even send faxes from DOS and Windows
applications.  Simply print to a printer port (LPT3 by default) as if it were
an IBM Proprinter X24E.  Faxworks will automatically log all traffic so that
you can review it at any time.  It supports drag and drop faxing, and it is
even integrated with the phone book in IBM Works.

- IBM Works.  Real word processing (with spell checking), database, charting,
spreadsheet, address book, phone book, calendar, and other applications for
getting essential work done, right out of the box, with OS/2 Warp.  All these
applications are tightly integrated, thanks to OS/2 Warp's System Object
Model.  Drag a spreadsheet into your word processing document and it's linked.
No arcane menu options or contortions required.  The IBM Works Event Monitor
will even notify you when you have an appointment you need to keep and, thanks
to OS/2 Warp's real multitasking, you won't miss that notification just
because your computer is doing something else.

- Multimedia Viewer.  An application which gives your computer the ability to
deal with "foreign" multimedia files, everything from Kodak Photo CD images to
Sun .AU audio files from the Internet.  There's even a Light Table (a new
folder type which you can use anywhere in the Workplace Shell) which gives
thumbnails of all your bitmaps and images to let you catalog and categorize
your collection.  If you are a photographer, or use desktop publishing, think
of all the time you'll save.

- Video IN.  Formerly a $199 product by itself, IBM Ultimedia Video IN is
included free of charge in the BonusPak.  Winner of Byte Magazine's Best of
Comdex award, Video IN lets you record software motion video files (AVI files)
in either Ultimotion or Indeo formats.  You can record in real time or from
still images (images which come either from sets of bitmaps or from a computer
controlled laserdisc player).  Many popular video capture cards are supported
for recording from external video sources.  However, you don't need a video
capture card to use Video IN.  You can construct an animated weather sequence
(like the ones you see on television) from weather images you download from
the Internet, for example.

o DOS and Windows capabilities.  With the new Windows FastLoad option, you can
preload all of the Windows environment under OS/2 Warp when you boot, so that
Windows applications that you start from the Workplace Shell pop up in no time
flat.  And OS/2 Warp supports those very few applications which require Win32s
(such as MathCAD).  For DOS and Windows programs, OS/2 adds better virtual DMA
handling, which means applications such as games will run smoother and faster.
And creating a program object for a DOS or Windows application will
automatically pull in the correct settings from OS/2's database -- it's no
longer a separate procedure.  IBM even includes settings for over 250 of the
most popular DOS, Windows, and OS/2 games.

o System recovery options.  What did you do if OS/2 couldn't boot?  You may
have had to reinstall in the past.  No longer.  Now OS/2 Warp comes with
several great features to let you figure out what went wrong (and, more
importantly, to prevent something from going wrong in the first place).  A
small OS/2 character mode text editor is now included on your OS/2 Warp boot
diskettes, so you can change critical files without the Workplace Shell, if
need be.  You can now make a set of utility diskettes (for emergencies) using
a program in the System Setup folder.  A Maintenance Desktop is provided
alongside your regular desktop (and you can even use it while OS/2 Warp itself
is installing).  When you boot OS/2, you will now see a white box in the upper
left hand corner followed by "OS/2."  Hit ALT-F1, and a menu pops up with
several options (such as immediately dropping to a command line, using
archived desktops, etc).  You can even choose to have this menu display at
every bootup, with or without a timeout.  Hit ALT-F2, and you see a list of
every device driver load, as it loads, so if your system is stalling you can
determine the exact problem.  There are queue enhancements to prevent lockups.
Hit CTRL-ESC if an application grabs control of the input queue, and you are
back in charge much quicker.  Plus you can now (optionally) enable type ahead,
so that you can start typing before an application loads.

o Multimedia enhancements.  Beyond the features in the BonusPak (Video IN and
the Multimedia Viewer), the base OS/2 multimedia features have been enhanced
and improved.  Support is built-in for compressed audio formats (including
ADPCM) so that you can record and play back WAV files which take up far less
disk space.  MPEG video is supported with the Reel Magic card.  You can
display live video signals in a window on your OS/2 desktop with such cards as
the Win/TV.  Performance is much improved, and the amount of memory required
for multimedia is lower.  New system sounds and sound effects are provided.
Additional multimedia files (including Kodak Photo CD images) are included on
the CD-ROM version of OS/2 Warp.  The DIVE (Direct Interface Video Extensions)
API has been enhanced, to better support fast action games and animation under

o Miscellaneous.  There are literally thousands of other improvements in OS/2
Warp.  For example, the credits screen is now back.  If you have installed the
optional bitmaps, you can now find out who created OS/2 Warp by clicking once
on the desktop background and pressing CTRL-ALT-SHIFT-O (i.e.  hold down CTRL,
ALT, and SHIFT, and tap the letter O key).  Color palettes have been separated
into Mixed Colors and Solid Colors, so you can pick colors that will look good
even on a 16 color VGA system.  Scheme palettes are larger and have more
exciting selections.  The Information folder contains quite a bit more
detailed information and many more documents (while the plain text README file
has rightly shrunk) on topics such as performance considerations and Windows
programs in OS/2.  The Tutorial is both artistic and useful, with a button for
Windows users to learn equivalent functions, a Practice button (to let you
practice new steps), and a Do It button (to let the Tutorial actually perform
a task, such as opening the Games folder).  The OS/2 Mahjongg game is included
in the base installation.  DOS programs such as the DOS Editor and MSD, and
the Win-OS/2 Program Manager, are automatically placed as program objects in
the appropriate folders.  Adobe Type Manager can now be turned off for Windows
programs (the default).  A SESSION_PRIORITY setting allows for boosting the
responsiveness of individual DOS or Windows programs.  OS/2 Warp will install
over (and use, for running Windows applications) Windows 3.1 and 3.11, and
Windows for Workgroups 3.1 and 3.11.

The best news is that, aside from the much maligned applets in OS/2 2.x,
nothing was taken away from OS/2 Warp.  The most popular 32-bit operating
system for the PC was simply made better for everyone.

What versions of OS/2 Warp are available?

OS/2 Warp will be available across the entire range of OS/2 products.  OS/2
Warp Version 3 is the first.  This product is an upgrade for DOS, Windows, and
OS/2 for Windows users.  It uses an existing copy of Windows or Windows for
Workgroups on your PC's hard disk to provide compatibility with Windows
applications.  (If a copy of Windows is not available, OS/2 Warp Version 3
will still support DOS and OS/2 applications.)

Next, OS/2 Warp Version 3 with Win-OS/2, now available, is designed as an
upgrade for "full pack" OS/2 users or for new PCs without DOS/Windows.  It is
identical to OS/2 Warp Version 3 except that it contains Windows code (to run
Windows applications).

Other versions of OS/2 Warp (for SMP and networking) are also planned.  If you
purchase OS/2 Warp now, a discounted upgrade to the so-called network version
of OS/2 Warp will be available.  (The upgrade consists of a larger BonusPak;
the base OS/2 Warp software does not fundamentally change.)

Can I upgrade from "full pack" OS/2 2.x to OS/2 Warp Version 3?

The short answer is no, that OS/2 Warp Version 3 with Win-OS/2 is a more
convenient upgrade.  However, if you are willing to reformat, you can purchase
and install OS/2 Warp Version 3 to run DOS and OS/2 applications.  If you
install Windows before installing OS/2 Warp Version 3, you can also run
Windows applications.  IBM does not recommend such an upgrade without
reformatting.  Or, at the very least, you should completely remove all traces
of OS/2 (with Win-OS/2) from a diskette boot.  That means you should remove
the following directories:


and the following files:


Since I have to install Windows from DOS, how can I create an OS/2 Warp
Version 3 system with 100% HPFS?

If you wish to run with no DOS (FAT) file systems (all HPFS), it is more
convenient to use OS/2 Warp Version 3 with Win-OS/2, now available.  However,
it can still be accomplished with OS/2 Warp Version 3 (without Win-OS/2) by
following these steps:

   1. Create an empty FAT drive on any PC;

   2. Boot DOS from diskette and escape to the command line;

   3. Insert Windows Diskette 1 in Drive A and enter SETUP;

   4. Install Windows (Custom install preferable);

   5. Using a utility such as PKZIP, create a set of diskettes which contains
      the entire contents of the \WINDOWS directory just created;

   6. Install OS/2 Warp Version 3, reformatting everything to HPFS in the

   7. From a DOS command line, restore the contents of the \WINDOWS directory
      to the same drive (Drive C, for example) where it was originally
      installed and set these backup diskettes aside for future use
      (label them "Win-OS/2");

   8. Run OS/2 Warp's Selective Install, pass by the first panel, and make
      sure that the checkbox next to Win-OS/2 is checked, then click on
      the Install button;

   9. Insert original Windows diskettes when prompted;

  10. Shutdown and reboot.

Alternatively, you can use a free utility called WSETUP, available from (3.2)
Shareware and Freeware Sources, to install Windows 3.1 from within OS/2 Warp.
Or you can use a new product, Partition Magic from PowerQuest, which can
convert a DOS FAT hard disk into HPFS, on-the-fly, retaining all existing
files in the process.

Does OS/2 Warp support Windows VxDs?

No.  OS/2 Warp Version 3 does not support VxDs (or, more precisely, VxDs which
compromise system integrity are not supported).  Microsoft is actively
discouraging use of VxDs (because applications which use them cannot run under
NT and may not run under Windows95), and IBM recommends that you not invest in
software which requires them.  Most software vendors will probably be
releasing updates of their products which do not use VxDs (or native OS/2 Warp
versions of their applications).

Fortunately, the number of applications which require VxDs is very small, and,
of those applications, most are related to networking (for which there are
most often superior native OS/2 alternatives).

Will OS/2 Warp Version 3 get rid of my DOS and Windows when I install it?

Absolutely not.  Like a good application would, OS/2 Warp Version 3 leaves
your native environment untouched, so you can always return to it safely and
conveniently.  DOS/Windows is preserved using DualBoot by default.  (Boot
Manager is also available.)  You can even use OS/2 Warp's OSDELETE command
(from an OS/2 diskette boot) to remove OS/2 Warp should you wish to do so.
Install OS/2 Warp Version 3 with confidence.

Can OS/2 Warp read my drives compressed with Stacker, DoubleSpace, DriveSpace,
or SuperStor?

Not by itself.  It will safely ignore such drives if they exist.  If you would
like to continue using compressed drives, then Stacker Version 4 for OS/2 is
right for you.  Stacker for OS/2 can not only read and write Stacker
compressed drives, but it can also safely convert DoubleSpace, DriveSpace, and
SuperStor compressed drives to the more popular Stacker format.

How do I get OS/2 Warp Version 3?

Walk into any software dealership and ask for it.  It is readily and widely
available to all software dealers, either directly from IBM or through
distributors.  The best price is available through your dealer, although you
can order the product from IBM directly.

How much does OS/2 Warp Version 3 cost?

With all of OS/2 Warp's features, including the BonusPak, the U.S.  single
unit price is usually under $80 (list price is $129).

Discounted upgrades to OS/2 Warp Version 3 are available for the following
users (U.S.  terms):

o OS/2 for Windows (purchased August 1, 1994, to December 31, 1994):  $50 off
(only with rebate coupon affixed to box).

o All other OS/2 for Windows users:  $25 off (only with in-store rebate
coupon, if available).

OS/2 Warp Version 3 with Win-OS/2 has a list price of $199.  A discounted
upgrade to OS/2 Warp Version 3 with Win-OS/2 is available to all OS/2 2.1x
"full pack" users and carries a list price of $129.  Estimated street price on
the upgrade is under $80.

Other discounts may apply for additional licenses, VALU agreements, etc.
Pricing and availability may vary outside the United States, so consult your
local OS/2 software dealer for details.

OS/2 Warp is available on what types of media?

OS/2 Warp Version 3 (and OS/2 Warp Version 3 with Win-OS/2) are available on
3.5 inch diskettes and CD-ROM (with 3.5 inch boot diskettes).  OS/2 is no
longer available on 5.25 inch diskettes.  See (4.2) Installing OS/2 Warp from
Drive B.

How much does it cost to use the IBM Global Network for the Internet

Rates vary by country, so no one answer will necessarily apply.  The latest
rate information for your country is displayed when you first register with
the IBM Global Network using OS/2 Warp's Internet Connection.  You are asked
then to agree to the terms.  Three hours of free access are provided with
every copy of OS/2 Warp, and you will not incur any charges until you use more
than three hours or fail to cancel your account within three months of

In the United States, there are two primary rate plans:  either $12.95 for 6
hours per month or $29.95 for 30 hours per month (with per hour charges for
additional hours).  Generally speaking, you will enjoy lower rates for
accessing the Internet through the IBM Global Network if you do not live in a
major city (where other Internet providers may be competing) or if you travel
and need access from two or more locations.  The IBM Global Network provides
worldwide access with local dial-up numbers all over the world.  Most other
Internet providers only provide service within a specific metropolitan area.
OS/2 Warp provides the capability to connect either with the IBM Global
Network or an Internet provider of your choice, so you should feel free to
shop for the most attractive rates for your situation.  Most independent
Internet providers will readily assist you in configuring OS/2 Warp to access
their services, so do not hesitate to ask.

Can I use Warp's Internet Connection with IBM TCP/IP for OS/2?

Yes.  This combination is now supported by IBM.  Make sure that you install
the latest Service Pak(s) for IBM TCP/IP for OS/2, however.  Also, when the
OS/2 Warp Internet Dialer is active, all TCP/IP traffic will be routed through
your dial-up connection (and traffic through your network card will be
suspended).  When you close the Dialer, traffic will resume through your
network card.

I can't wait for the so-called network version of OS/2 Warp.  How do I get
OS/2 Warp to use my network card to access the Internet?

Assuming your network card is connected into the Internet already (perhaps at
a university), any of the following software packages will allow OS/2 Warp's
Internet software to work over your network card:

  o IBM LAN Server 4 Requester (Client) for OS/2
  o IBM DCE Client Kit for OS/2
  o IBM AnyNet/2
  o IBM TCP/IP Version 2 for OS/2 Base Services Kit with latest Service Pak

The least expensive of these (under $50 typically) is the LAN Server 4
requester.  However, it is not sold separately with diskettes.  The diskettes
for the requester are bundled with IBM LAN Server 4. If you know someone who
has IBM LAN Server 4, you can legally obtain a copy of the requester from that
person if you purchase a separate license card for the requester from IBM or
any IBM software dealer.

The DCE Client is the second least expensive (under $65 typically) method, and
diskettes are provided (not just the right to copy) when you purchase it.

Please note that when you are using OS/2 Warp's Internet Dialer, all traffic
will be routed over the dial-up connection and any traffic over the network
card will be suspended.  If you close the Internet Dialer, traffic over your
network card will resume.  Also please be advised that IBM has not completed
testing on OS/2 Warp's Internet Connection in combination with any product
which provides TCP/IP for network cards except for IBM TCP/IP Version 2 with
the latest Service Pak.  Nonetheless, many OS/2 Warp users are using these
suggested combinations of products with great success and little apparent
difficulty.  IBM expects to officially "bless" these suggested combinations in
the near future.

Will all my current software work with OS/2 Warp?

With very few exceptions, yes.  IBM has tested OS/2 Warp against huge numbers
of applications and networking packages, including the Novell Netware Client
Kit for OS/2, Communications Manager, IBM TCP/IP for OS/2, the LAN Server
requester, and much more.  Any specific application notes are contained in the
Application Considerations online document, located in the Information folder
in OS/2 Warp.

 What is OS/2 Warp?

OS/2 Warp is an advanced operating system for PCs with an 80386 processor or
better.  It was developed by IBM as the successor to DOS, the operating system
developed for the original IBM PC.

OS/2 started as a joint project between IBM and Microsoft in the mid 1980s and
was first released in late 1987 (at that time designed for the IBM PC/AT and
other 80286-based systems).  Microsoft was a public and vocal supporter of
OS/2 for years, issuing several of its own releases and promoting OS/2
application development.  Bill Gates, for example, stated that, "...OS/2 is
the platform of the '90s."  However, OS/2 versions from 1.3 onward have been
the responsibility of IBM.

OS/2 Warp was designed from the ground up with preemptive multitasking and
multithreading in mind.  "Preemptive multitasking" means that the operating
system is responsible for allocating processor time to the one or more
applications which are running.  (Cooperative multitasking, as found in
Microsoft Windows or the Macintosh's System 7, requires that each application
surrender the processor after a certain amount of time.  If one application
refuses to yield, all the other applications stop running.)  "Multithreading"
means that programs can start subtasks which will then be executed by the
operating system in the background.  For example, a word processor may create
a separate thread (subtask) to handle printing or saving to disk.  When the
user asks the word processor to perform one of these tasks, the word processor
creates a new thread and control returns to the word processor (and the user)
immediately.  The subtask is executed by the operating system in the
background.  The user is then free to ask the word processor to perform
another task without waiting for the thread to complete.  Applications which
utilitize multithreading can be much more responsive to the user.

OS/2 Warp also protects applications from one another (a single misbehaved
program will not typically disrupt the entire system), supports all
addressable physical RAM, and supplies virtual memory to applications as
requested, breaking DOS's 640K barrier.

An OS/2 Warp demonstration diskette (which will run on any PC with VGA or
better, and DOS or OS/2) is available from IBM by calling 800-3-IBM-OS2.  The
OS/2 Warp demo diskette may also be downloaded; see (3.2) Shareware and
Freeware Sources.

(1.2) Differences Between Versions

 What are the differences between versions?

o IBM OS/2 Warp, Version 3 is the newest and most advanced version of OS/2
ever created.  This release is aimed squarely at the rapidly growing home and
small business software market.  Yet, in addressing the concerns of these
demanding consumers, it offers significant advantages to the large number of
traditional IBM and OS/2 users, including those in big businesses and
government.  A few of the enhancements include a BonusPak of full fledged
applications (including one button access to the Internet), the LaunchPad,
many more device drivers, and significant performance improvements.  Please
see (0.4) Special Report on OS/2 Warp for more information.

o IBM OS/2 Version 2.1 is the previous release of OS/2, which added Windows
3.1 compatibility, multimedia support (including software motion video), and
more device drivers.  With Version 2.1 IBM ended the practice of including
extra features in its own, preinstalled versions of OS/2 that were not found
in the off-the-shelf package.  OS/2 2.1x and OS/2 for Windows propelled OS/2
into the mainstream PC marketplace.  The latest Service Pak for OS/2 2.1 is
level 06300.

o IBM OS/2 Version 2.0 is the first release of OS/2 which will run only on
machines with an 80386SX processor or better.  With this release IBM started
developing OS/2 (and its Intel and non-Intel-based successors) independently
but continued to involve third party PC manufacturers in its testing.
Improvements included an object-oriented Workplace Shell (WPS); a multiple
operating system boot mechanism; better DOS and Windows support [see (1.3) DOS
and Windows Compatibility]; new 32-bit programming interfaces; support for
more than 16 MB of physical RAM [see (2.6) More Than 16 MB RAM]; and more
third party device drivers.  OS/2 1.x applications, unmodified, still run
under OS/2 2.0 (and later).

o IBM OS/2 Version 1.3 is the last release of OS/2 to operate on PCs with
80286 CPUs.  This version introduced built-in Adobe Type Manager (ATM) [see
(5.5) Adobe Type Manager], providing scalable typefaces for screen and
printer.  Procedures Language/2 (REXX), a powerful batch-oriented programming
language, became a part of Standard Edition with this release.  [See (5.11)
REXX.] (A few vendors are shipping Microsoft OS/2 Version 1.3, but Microsoft
has ceded all OS/2 development to IBM.)

o OS/2 Version 1.2 was the first to incorporate the High Performance File
System (HPFS) [see (1.5) High Performance File System].  With this release IBM
OS/2 added a dual boot mechanism and IBM Extended Edition [see (3.10) Extended
Services] introduced REXX.

o OS/2 Version 1.1 was the first to include the Presentation Manager (PM)
GUI/API.  Microsoft OEM versions added a dual boot mechanism with this

o OS/2 Version 1.0, introduced in late 1987, was the first release of OS/2.
Task switching was accomplished using a character-based shell and limited DOS
compatibility was provided.

Versions of OS/2 from 2.1 on have been made available in two packages:  one
containing built-in Windows code to run Windows applications (sometimes called
the "with Win-OS/2" or "full" package) and the other which can use an existing
copy of Windows (optional) to run Windows applications (the "for Windows" or
"without Win-OS/2" package).

(1.3) DOS and Windows Compatibility

 How good is OS/2 Warp's DOS and Windows compatibility?

OS/2 1.x [see (1.2) Differences Between Versions] justifiably earned a
reputation for poor DOS compatibility.  Since it was hampered by the 80286, it
could not run more than one DOS application at a time.

The situation changed dramatically with OS/2 2.0, and OS/2 Warp adds further
refinements.  OS/2 Warp Version 3 preemptively multitasks DOS and Windows
(standard and enhanced mode, including Win32s) applications in separate,
protected sessions.

OS/2 Warp provides a complete DOS emulation equivalent to DOS 5.0 or later.
The operating system can provide each DOS application with up to 32 MB of EMS
4.0 (expanded memory), 16 MB of XMS 2.0 (extended memory), and/or 512 MB of
DPMI 0.95 (DOS Protected Mode Interface extended memory), all from its pool of
physical and/or virtual memory (meaning you do not have to have as much RAM in
your system as your applications request).  These limits are in addition to
the up to 730K free conventional memory supplied to each DOS application, even
after mouse and network drivers [see (3.8) Networking Products] are loaded.
As in DOS 5.0 or later, DOS code and device drivers may be loaded into high
memory.  A 386 memory manager like QEMM is not needed -- these features are
provided by OS/2 Warp directly.

The DOS emulation allows customization of device driver sets -- each DOS
application shares a systemwide CONFIG.SYS and the equivalent of its own
CONFIG.SYS.  Also, there is a systemwide AUTOEXEC.BAT file; however, batch
commands particular to each DOS application can be invoked using separate,
application-specific AUTOEXEC.BAT files.  And many DOS Settings are provided
to fine tune [see (5.6) Performance Tuning] each DOS/Windows application's
behavior (e.g.  IDLE_SENSITIVITY and SESSION_PRIORITY).  Most of the popular
DOS/Windows applications on your hard disk will be migrated automatically when
you install OS/2 Warp, so that program icons will be set up for them.
Applications which are automatically recognized include over 250 of the most
popular DOS, Windows, and OS/2 games.

In addition, OS/2 Warp will boot one or more specific versions of DOS in
separate sessions, to assist in running particularly difficult applications
(e.g.  DOS networks, MSCDEX and CD-ROM drivers).  So, for example, it is
possible to multitask DOS 3.3, DOS 4.0, DOS 5.0, DOS 6.0, DOS 6.2, PC-DOS 6.3,
DR-DOS, OS/2 Warp's DOS, and Desqview running atop DOS, all in separate
sessions, either windowed or full screen, all with the same and/or separate
device drivers, TSRs, environment variables, etc.  DOS boot images may be
stored on a hard disk.  These procedures are described in the online Command
Reference (under VMDISK), Master Help Index, and in the printed manual.  [See
also (5.9) Specific DOS Sessions.]

Standard graphics modes [generally up to VGA resolutions; see (2.2) SuperVGA
Support] are supported in DOS windows, as are selectable text mode fonts.
Cut/paste to/from windowed DOS applications is supported (to/from other DOS,
OS/2, and Windows applications), including graphics cut/paste.  Theoretically,
OS/2 Warp can run up to 240 simultaneous DOS/Windows sessions; the practical
maximum depends on your PC's performance.

OS/2 Warp will, in fact, run virtually all DOS applications in existence,
including notorious ones such as Microsoft Flight Simulator, Wing Commander,
Maple, MatLab (Version 3.5k or later), AutoCAD (Release 12 requires
maintenance version C2 or later), and others.  Those that do not run generally
fall into the following categories:

1. Programs that use Virtual Control Program Interface (VCPI) memory extenders
or other extenders which require direct access to 80386 control registers.
Since such applications are also all but incompatible with Windows, most
vendors have updates for DPMI compatibility;

2. Applications which attempt to directly address the physical sectors of an
OS/2 managed nonremoveable hard disk drive.  Such programs include UnErase in
Norton Utilities [see (3.4) Disk Utilities].  Fortunately OS/2 Warp has a
built-in UnDelete feature which is more robust than Norton's approach.
(Consult the online Command Reference for information on how to enable

3. Timing sensitive DOS applications.  Certain DOS programs that generate
digitized sound through the PC's internal speaker may have distorted sound.
High speed, real time data collection may be compromised.  These problems can
often be minimized or even eliminated using OS/2 Warp's DOS Settings,
including the SESSION_PRIORITY setting.

4. Certain DOS programming debuggers.  DOS applications running under OS/2
Warp are not permitted to access debug registers DR0-DR7 from a DOS session.
Also, DOS debuggers will not be able to set hardware breakpoints, and all
read/write operations to debug registers in virtual 8086 mode will be ignored.

See (3.12) Backup Software for information on OS/2 backup issues.

DOS-based disk caching software is not required since OS/2 Warp includes a
built-in, highly configurable, efficient disk cache (available even for
CD-ROMs).  See the online Command Reference for details.

DOS programs running under OS/2 Warp are extremely fast.  A single DOS
application (no other applications open) running full screen under OS/2 Warp
typically achieves 95-97% of the performance it would have under native DOS.
If the DOS application accesses the hard disk frequently, such as with
database software, it can actually operate up to several times faster than it
would if running under native DOS.

If pure DOS is absolutely required, OS/2 Warp includes a utility called the
Boot Manager.  The Boot Manager can provide a listing of all the operating
systems available on the system and will allow selection of any one at
startup, with a default after timeout.  The OS/2 DualBoot method (to switch
between DOS and OS/2 only) is still available as well.  Consult the printed
OS/2 Warp manual for instructions on how to use Boot Manager or DualBoot.
Note that OS/2 Warp need not be installed on Drive C -- it can reside on other
volumes [see (4.3) Hard Disk Partitioning].

Compatibility with Windows, a popular DOS extender, is provided by either
Win-OS/2, an environment based on Microsoft's Windows source code, or by an
actual copy of Windows 3.1, Windows 3.11, Windows for Workgroups 3.1, or
Windows for Workgroups 3.11.  See (1.2) Differences Between Versions for
details.  OS/2 Warp supports Windows 3.x enhanced mode (including Win32s) and
standard mode applications, either on a full screen Windows desktop (with the
familiar Program Manager and one or more Windows applications) or
"seamlessly," alongside OS/2 applications on the Workplace Shell desktop.
"Seamless" operation is available with all video drivers that ship with OS/2
Warp (VGA or better).  [See (2.2) SuperVGA Support.]

Several icon conversion utilities can convert Windows icons for use by the
OS/2 Icon Editor and/or OS/2-specific programs [see (3.2) Shareware and
Freeware Sources].  (No conversion is necessary if the icons are to be used
with Windows programs running under OS/2 Warp.)

OS/2 Warp directly provides all Windows enhanced mode features save one:
support for Windows virtual drivers (VxD).  Services provided by WINMEM32.DLL
and Win32s are supported.  See (0.4) Special Report on OS/2 Warp for more

Windows applications are well integrated into the overall OS/2 Workplace Shell
environment with DDE and Clipboard hooks, and OLE (Object Linking and
Embedding) is supported among Windows applications.  Adobe Type Manager [see
(5.5) Adobe Type Manager] comes with OS/2 Warp (for both OS/2 and Windows
applications), and TrueType fonts still work fine with Windows applications.
Windows screen (for a full screen desktop) and printer device drivers will
work under Win-OS/2 [see (2.2) SuperVGA Support].  Such notorious Windows
applications as Word, Norton Desktop (save portions described above),
Toolbook, and After Dark work fine under Win-OS/2.  Even applications which
rely on the Windows Multimedia Extensions ( supplied as part of Windows and
Win-OS/2) operate without trouble.  [See (3.6) Multimedia for information on
the OS/2 multimedia extensions, MMPM/2.] Even the Windows applets run just

OS/2 Warp's Windows support (called Win-OS/2) departs from plain Microsoft
Windows in that it allows more than one Windows desktop and can preemptively
(rather than cooperatively) multitask Windows applications in separate,
robust, protected sessions, at the user's option.  Also, both DOS and OS/2
applications can be started from the Win-OS/2 Program Manager.

In short, OS/2 Warp is generally regarded as the most DOS and Windows
compatible among the new crop of 32-bit operating systems (NT included).  It
is also generally regarded as a better DOS multitasker than Desqview.

(1.4) Availability and Cost of OS/2 Warp

 Where can I buy OS/2 Warp, and how much does it cost?

In the United States IBM OS/2 Warp Version 3 is available directly from IBM by
calling 800-3-IBM-OS2.  Call for the latest information on pricing --
promotional pricing may be in effect.  Both diskette (3.5 inch media) and
CD-ROM versions are available.  The CD-ROM version contains diskette images
(so you can create a set of installation diskettes from the CD-ROM) as well as
extra multimedia and Kodak Photo CD files.  Express shipping is provided with
all orders placed through this toll free number.

IBM part numbers are as follows:

  83G8710        OS/2 Warp with Win-OS/2 Upgrade (ALC)

Upgrade packages are designed to upgrade OS/2 2.1 or 2.11.  "ALC" means
Additional License Certificate, in other words simply a license card (without
manuals or media) representing the right to use OS/2 Warp on an additional PC.

OS/2 Warp is now available from almost any software dealer (including
Corporate Software, Egghead, Software Etc., and many others).  Software dealer
pricing is lower than that available directly from IBM -- often $10 or $20

OS/2 Warp costs about the same as Microsoft Windows for DOS and roughly one
fifth to one third as much as the base (not to mention server) versions of
Windows NT, NeXTStep, Solaris, and UnixWare.

In Canada phone 800-465-1234 to order.  In the U.K.  phone the OS/2 Solution
Centre at 0285-655888 or IBM at 0256-841818 or 0800-919-929.  In all
countries, any IBM software dealer or office can fulfill your OS/2 Warp order.
Pricing varies from country to country.

IBM is trying to make OS/2 Warp available everywhere DOS is purchased.  If
your dealer does not stock OS/2 Warp, take your business elsewhere (and
explain why).  IBM bundles OS/2 Warp with most new PCs, and several other
vendors, including AST, Compaq, Everex, Northgate, ALR, Unisys, Dell, Ariel
Design, Vobis, Escom, Toshiba, Osbourne, and Tangent, will either preload OS/2
Warp automatically or by request.

IBM offers two money back guarantees in the U.S.:  a 30-day, no questions
asked, money back guarantee, and a 90-day compatibility guarantee [see (2.1)
Hardware Requirements].

If you intend to purchase many copies (usually over 100) of any IBM software
product (including OS/2 Warp), be sure to ask your software dealer or IBM
representative about VALU agreements.  Using VALU, you can save significant
amounts of money on your software purchases and benefit from special

In many countries outside the United States, a fully functioning 45-day trial
version of OS/2 Warp on CD-ROM is available through PC oriented magazines,
computer shows, dealers, and other outlets.

(1.5) High Performance File System (HPFS)

 Why should I use HPFS?  What does it offer me?  Does it work with DOS?

HPFS is an installable file system (IFS) provided with OS/2 Warp which may
optionally be used instead of (or alongside) the standard DOS-style FAT (File
Allocation Table) file system.  HPFS offers long file names (up to 254
characters including the path, greatly exceeding the "8 dot 3" limit in DOS's
FAT file system), contiguous storage of extended attributes (without the EA
DATA.  SF file used by FAT), resistance to file fragmentation, improved media
error handling, smaller cluster size, support for larger file storage devices
(up to 512 GB), and speedier disk operation, particularly on large hard disks,
on systems with more than 6 MB of RAM.  HPFS is not case sensitive, although
it does preserve case in file names.

However, HPFS is not currently supported on removeable media, although some
programs (e.g.  BACKUP) preserve long file names on such FAT disks.  Also,
native DOS cannot access a HPFS partition without a special utility.  However,
DOS/Windows sessions running under OS/2 can use all files that conform to the
"8 dot 3" naming conventions, even if they are stored on HPFS volumes.  (FAT
is not required for compatibility with DOS and Windows applications running
under OS/2 Warp.)

Note that PowerQuest has released Partition Magic, a utility which can convert
the DOS FAT file system to OS/2 HPFS on-the-fly, leaving all your files
intact.  Partition Magic also allows you (free space permitting) to
repartition your hard disk without destroying any files.  This utility can
save an enormous amount of time in managing your hard disks.  Contact your
favorite OS/2 Warp software dealer to order Partition Magic.

(1.6) Why Choose OS/2 Warp?

 Why should I choose OS/2 Warp over its competitors?

There are many products which compete with OS/2 Warp, at least to some extent.
Before comparing OS/2 Warp with those products, it is important to understand
what strengths OS/2 Warp brings to the table.

OS/2 Warp requires a PC with a 386SX (or better) and preferably 6 MB of RAM
(or more).  If you do not have the hardware required to run OS/2 Warp (and
cannot conveniently upgrade), other choices should be considered.  However,
OS/2 Warp is considered by far the "lightest" (in terms of resource
requirements) of all the new crop of 32-bit operating systems (which includes
Microsoft NT, NeXTStep, Novell UnixWare, and Solaris).  Furthermore, IBM has
made great strides in reducing the amount of memory required by OS/2 Warp.  A
PC which is well-equipped to run Windows for DOS is also well-equipped to run
OS/2 Warp.

OS/2 Warp is based on a stable, proven design (which started with OS/2 1.0,
introduced in 1987).  Today's OS/2 Warp barely resembles Version 1.0, yet
applications written for that version still run under OS/2 Warp, unmodified.
OS/2 1.x found ready markets in so-called "mission critical" applications,
including automatic teller machines for banking, point-of-sale systems,
process control and factory automation, network software, and more.  Other
operating systems (particularly NT) have not had the benefit of a long period
of testing and reliable operation.

As noted in (1.3) DOS and Windows Compatibility, OS/2 Warp is generally
acknowledged to be the most DOS and Windows compatible 32-bit operating system
on the market.  OS/2 Warp users have access to the broad range of software
written for these environments (in addition to the growing library of native
OS/2 Warp software) without sacrificing compatibility or performance.  Again,
this ability stands in contrast to the mediocre DOS and Windows compatibility
(and performance) found in such operating systems as NT, NeXTStep, Solaris,
UnixWare, Linux, and others.  NT, for example, cannot tolerate most DOS device
drivers, has no specific DOS session features, and will not run DOS graphics
applications in windows on the desktop.  (NT also does not include any support
for PCMCIA cards or Advanced Power Management, so common in notebook
computers.)  IBM calls OS/2 Warp "the integrating platform" because it
actually lends functionality to all applications, even if you only run DOS and
Windows programs.

Currently DOS (with or without Windows) is the most common operating
environment on PCs (with OS/2 Warp in second place and closing the gap).  OS/2
Warp provides several advantages over plain DOS/Windows, such as:

Preemptive multitasking.  OS/2 Warp can run more than one application at the
same time, and no application can ever take all the CPU attention away from
the other tasks.  Downloading files, formatting diskettes, printing,
mathematically intensive tasks, and other computer-hogging jobs can run
reliably, in the background, freeing your computer so you can work more
effectively and save time.

Multithreading.  OS/2 Warp applications can be written to use threads (also
known as subtasks).  Threads also run in the background so that an application
never stops responding to your input.  For example, with the DeScribe word
processor's multithreaded printing, you can tell the application to print the
file then immediately make another revision, without waiting for the document
to even spool to the print queue.

Enhanced Configurability.  Your DOS applications, for example, can have
individually tailored CONFIG.SYS settings -- no rebooting required.  So, if
you want to play that game of Wing Commander, you do not have to get rid of
your TSRs and network drivers beforehand.

Crash Protection.  Every application running under OS/2 Warp is isolated from
all the other applications.  If one application decides to write to random
areas of memory, OS/2 Warp will promptly notify you of the offense.  All your
other applications continue to run, unharmed.  Neither DOS nor Windows offer
such complete protection.  For example, if you have a Windows application
which likes to crash (cause a GPF error), OS/2 Warp can run it in a separate
Win-OS/2 session.  If the application self destructs, all your other DOS,
Windows, and OS/2 Warp applications which may be running never miss a beat.
No operating system is totally crash proof, but OS/2 Warp is widely considered
to be extremely reliable, both because of its design and because of its

Workplace Shell.  Literally millions of dollars are spent on Windows desktop
replacements and accessories (such as Norton Desktop, PC Tools, and so on).
If you do not like the Windows Program Manager and File Manager (still
available under OS/2 Warp), OS/2 Warp's Workplace Shell is worthy of your
attention.  Folders can be nested.  Objects (including files) can have long
names (so you don't have to remember what "Y6EDGQTR.ILK" means).  Your desktop
is almost infinitely customizable:  every folder can have a different color or
background, for example.  And consistency is maintained throughout the
Workplace Shell.  Want to print a file?  Drag it to the printer object.  Fax
it?  Drag it to the Fax object.  Open it?  Drag it to an application program
object.  Delete it?  Drag it to the Shredder.

Access to OS/2 Warp Applications.  There's only one way to add OS/2 Warp
applications to your PC:  add OS/2 Warp.  Many of these applications are not
available for any other operating system.  For example, Watcom's VX-REXX and
HockWare's VisPro/REXX let you create fully graphical applications in no time
flat.  (VX-REXX recently won PC Magazine's Editor's Choice award.)  Lotus
cc:Mail for OS/2, which takes full advantage of the Workplace Shell, makes
e-mail simple.  IBM's Ultimedia Builder/2, Workplace/2, and Manager/2 are the
best multimedia authoring tools available anywhere, better than anything for
Windows, says PC Magazine.  And you can only play Galactic Civilizations for
OS/2, the Number 1 PC game according to a recent Internet list, when you're
running OS/2.  OS/2 Warp allows you to run the largest library of 32-bit
applications available for the PC.

OS/2 Warp costs less (much less) than its competitors.  OS/2 Warp is a best
seller and continues to gain ground on plain DOS/Windows, meaning application
developers and hardware manufacturers take notice (most recently Corel Systems
and Toshiba).  OS/2 Warp is likely to be the most popular operating system on
PowerPC systems.  OS/2 Warp coexists peacefully with your existing DOS/Windows
setup (using either DualBoot or Boot Manager), so you can make the switch at
your own pace.  OS/2 Warp continues to capture industry awards.  Most
recently, Windows Magazine named OS/2 to its Top 100 list.  And, for the
second straight year, OS/2 won Overall Product of the Year from the readers of
Infoworld.  (OS/2 also earned Infoworld's Software Product of the Year and the
Interoperability Award.  In fact, OS/2, with three of the highest awards all
to itself, was the only product to win more than one award.)  As an OS/2 Warp
user, you'll be joining the over eight million OS/2ers around the world who
are experiencing a new level of performance when they use their PCs.

But shouldn't I wait for Windows95 ("Chicago")?

Most industry observers believe that Chicago (Windows95) will not be available
until far into 1995.  In other words, Microsoft is promising a product which
will offer some of OS/2 Warp's features at some point in the future.  Even if
you think you are interested in Chicago, OS/2 Warp will not suddenly render
your PC unable to run it.  So why not upgrade to OS/2 Warp in the meantime?

Yet there are several good reasons why you may not be making that upgrade.
First, like most first releases, Chicago will suffer from its share of bugs.
It will take a considerable amount of time (and expense) to solve these
problems.  Second, OS/2 Warp is by no means standing still.  By the time
Chicago is released, OS/2 Warp could possibly enjoy another upgrade.  (The
time between new releases of OS/2 has been averaging about 14 months.  The
last major Windows update, Version 3.1, was introduced in April, 1992.)  In
other words, it will have features (such as support for Symmetric
Multiprocessing and the PowerPC) that are not even contemplated for Chicago.
Or, in still other words, vaporware (software which does not yet exist) always
sounds more appealing than real software on the surface, because software
vendors can make whatever claims they like.

Chicago will not support any OS/2 Warp applications (whose number is only
growing with time).  On the other hand, OS/2 Warp now supports the Win32s
programming interface for 32-bit Windows applications.  The resource
requirements for Chicago will increase over Windows 3.1 (at the same time IBM
has fine tuned OS/2 Warp to use less memory and perform better) -- at best
Chicago will demand a PC no less powerful than that demanded by OS/2 Warp.

Byte and Windows Sources have pointed to some architectural problems with
Chicago.  These publications have cited Chicago's pervasive use of 16-bit
subsystems (which will cause "thunking," i.e.  a performance hit for calls
made by 32-bit applications), failure to protect 16-bit Windows applications
from crashing the entire system (which OS/2 Warp already prevents), and the
16-bit locking mechanism (which means that 16-bit Windows applications will
not be preempted by Chicago, possibly resulting in hung background file
transfers, poor multimedia performance, and other problems, even for 32-bit
applications).  Moreover, reportedly all video and network device drivers for
Windows 3.1 must be rewritten to work with Chicago.  A recently published
book, "Undocumented Windows95," even suggests that new 32-bit Windows
applications may still depend on real mode vestiges from ordinary DOS.

Finally, Microsoft made similar promises (on the overwhelming success to be
achieved by NT and Windows for Workgroups, most recently).  These promises
have not come to pass.  It is far from certain whether Chicago will satisfy
the marketplace.

For a concise, researched, official view of OS/2 Warp when compared to the
as-yet-unreleased Windows95, IBM has published a whitepaper which is available
from online services such as CompuServe and the Internet.

(2.0) Hardware

 The following questions are addressed in this section:

 (2.1)  What hardware do I need to run IBM OS/2 Warp?  Do I need a PS/2?

 (2.2)  Will OS/2 Warp work with my SuperVGA adapter?

 (2.3)  Will OS/2 Warp work with my printer?

 (2.4)  Can I use COM3 and COM4 in OS/2 Warp?

 (2.5)  Are there any specific hardware recommendations?

 (2.6)  Can I use more than 16 MB of RAM?

 (2.7)  What device drivers are available that aren't included with OS/2 Warp?

(2.1) Hardware Requirements

 What hardware do I need to run IBM OS/2 Warp?  Do I need a PS/2?

You need any ISA (AT bus), EISA, VESA LocalBus, PCI, or Microchannel PC
compatible with at least an 80386SX CPU, 4 MB (6 MB or more strongly
recommended) of RAM, an 80 MB or larger hard disk (with 20-70 MB free,
depending on which features you wish to install), a supported video adapter
(CGA, EGA, VGA, SuperVGA, 8514/A, XGA, or third party driver) with appropriate
display (VGA or better strongly recommended), and a high density 3.5 inch
diskette drive for installation.  A mouse or other pointing device is strongly
recommended.  Allow extra RAM and hard disk space for OS/2-based networking
[see (3.8) Networking Products], Extended Services [see (3.10) Extended
Services], and/or extra system loads (i.e.  an extraordinary number of large
applications running simultaneously).  When calculating hard disk space
requirements, subtract space occupied by files already on the hard disk which
are functionally included in OS/2 Warp and may be deleted, e.g.  DOS, a 386
memory manager, Adobe Type Manager [see (5.5) Adobe Type Manager] with base
typefaces, etc.

The performance of OS/2 Warp itself will not be increased appreciably with the
addition of a math coprocessor.  However, certain applications may benefit.

The Workplace Shell (WPS) will not operate with the Monochrome Display Adapter
or the Hercules Monochrome Graphics Adapter.  Usually the WPS will fail to
work with monochrome EGA.  However, some EGA adapters (e.g.  Paradise
Monochrome EGA Card, ATI EGA Wonder) will emulate all color EGA modes on TTL
monochrome monitors and, thus, will work with the WPS.

The following dual monitor configurations are supported:  VGA (or most
SuperVGA) with Monochrome Display Adapter (not Hercules), 8514/A with VGA, XGA
with VGA, and XGA with one or more other XGA.  A secondary monitor is most
often used with code debuggers that explicitly support such configurations.
The Workplace Shell desktop is currently shown only on the primary display
(except for the STB MVP-2 and MVP-4 ISA and Microchannel display adapters
which do support the Workplace Shell desktop spanning multiple monitors --
contact STB at 214-234-8750 or FAX 214-234-1306 for more information; and the
Double Edge video card from Nth Graphics, phone 800-624-7552).

OS/2 Warp specifically supports hard drive adapters which conform to the
Western Digital chipset interface standard (nearly all MFM, RLL, IDE, and ESDI
adapters) and Adaptec, Future Domain, DPT, BusLogic, MediaVision/Trantor, and
IBM SCSI adapters.  [True OS/2 Warp drivers for most SCSI adapters, e.g.
Always, Trantor, Rancho, Procomp, Corel Systems, Seagate, Mylex, CE Infosys,
Ciprico, NCR, and others are available directly from the adapter manufacturers
or from (3.2) Shareware and Freeware Sources.] In addition, "generic" INT13
support is provided for all other hard disk adapters.  This "generic" support
even embraces such devices as Iomega's Bernoulli and SyQuest's removeable
media products (but for best results contact Iomega or SyQuest for an OS/2
Warp driver).

OS/2 Warp driver support is available for nearly all CD-ROM drives.  The list
below describes the drivers included with OS/2 Warp.  If your CD-ROM drive is
not on the list, it is in all likelihood a close cousin (or follow-on model)
to one of the CD-ROM drives on the list, and OS/2 Warp will automatically
recognize it using the closest match.  Be sure to ask the manufacturer of your
CD-ROM drive for advice if OS/2 Warp is not recognizing it.

Most IDE CD-ROM drives are also supported.  For CD-ROM drives that use their
own adapter cards (that are not attached to SCSI adapters), you may need to
know which interrupt (IRQ), DMA channel (if any), and port addresses are used
by the CD-ROM adapter in order to correctly configure OS/2 Warp.  Please
consult the printed OS/2 Warp manual for guidance.

OS/2 Warp's CD-ROM support includes audio, ISO 9660/High Sierra, CD-ROM/XA,
and Kodak Photo CD (including multisession) compatibility for those CD-ROM
drives which support these standards.  An OS/2 Warp CD-ROM device driver
automatically provides CD-ROM services to DOS and Windows applications running
under OS/2 Warp.  In other words, you do not need to load DOS CD-ROM device
drivers when you are running OS/2 Warp.  However, in the unlikely event you
cannot locate an OS/2 Warp driver for your CD-ROM drive, you may use the DOS
CD-ROM device drivers in a specific DOS session [see (5.9) Specific DOS
Sessions for details].

OS/2 Warp drivers for some non-SCSI Hitachi CD-ROM models are available by
calling either Laser Resources (800-535-2737) or Proline (415-692-5262); ask
for CDREXT5D.  Storage Devices offers OS/2 drivers for its parallel port
attached peripherals, including its CD-ROM drive.

See (2.3) Printer Support for information on OS/2 printer and plotter

OS/2 Warp is explicitly supported on non-IBM PC compatibles.  IBM is offering
a money back compatibility guarantee in the U.S.  Should OS/2 Warp fail to
work on your compatible within the first 90 days of use, and should IBM be
unable to fix the problem, your purchase price will be refunded.  To date over
2000 non-IBM models have been tested in IBM's own labs.

     - 90C31
     - 90C33
     - 90C11
     - 90C30

These chipsets are used in the vast majority of SuperVGA adapters.  OS/2 Warp
also supplies "generic" SuperVGA support for other chipsets (such as Chips &
Technologies and Realtek) which allows full screen DOS and Windows
applications to run in SuperVGA modes, but OS/2's Workplace Shell runs in VGA
resolution.  If a high resolution driver for your SuperVGA card is not
included with OS/2 Warp, contact the video card manufacturer for the correct
driver.  Many drivers included with OS/2 Warp support HiColor (65,536 colors)
and even TrueColor (16 million colors) modes if you have enough video memory.

Some SuperVGA adapters (notably ATI's Vantage and Ultra lines) are 8514/A
hardware compatible and will function in 1024x768 256 color mode with OS/2's
built-in 8514/A driver.

Regular Windows 3.1 display drivers may be used for the full screen Win-OS/2
desktop.  To install a Windows 3.1 display driver under Win-OS/2, simply
replace the fdisplay= entry in the SYSTEM.INI file with the name of the
Windows .DRV file supplied by the vendor, and copy the .DRV file to the
Win-OS/2 SYSTEM directory.  Note that you may have to use the EXPAND program
supplied with Windows or Win-OS/2 to decompress the vendor's .DRV file.

Settings for your SuperVGA display are controlled from the System object in
your System Setup folder (which is located inside the OS/2 System folder).
There you can change video modes and even set the refresh rates for those
modes according to your monitor's capabilities.

The above list is abbreviated; certain models are not listed.  If your printer
is not listed, consult both the OS/2 Warp printed manual and your printer's
manual to see if your printer emulates one of the above models.  For example,
the Canon BubbleJet Model BJ-10e printer works well with the IBM 4070 IJ

IBM, NEC, Canon, and other printer manufacturers have OS/2 Warp drivers for
their printers available for download from BBSes.  Contact your printer's
manufacturer for assistance.  These downloadable drivers include older IBM
models (such as the IBM 5152 Graphics Printer and 5201 Quietwriter I), NEC dot
matrix printers, and Canon laser and BubbleJet printers.  The IBM/Lexmark BBS
can be reached at 606-232-5653.

DOS and Windows printer drivers continue to work for DOS and Windows
applications.  Use the Win-OS/2 Control Panel to install Windows printer
drivers for use with OS/2 Warp.

  Printer Troubleshooting for OS/2 Warp

If you are experiencing trouble printing, be sure to consult the "Printing in
OS/2" online document (located in your Information folder) and the OS/2 Warp
printed manual for assistance.  Common problems are usually solved using one
of the following methods:

1. If you are using a Postscript printer, and you are having difficulty
printing with Windows applications, particularly over a network, try adding
the following line to the Postscript section of your WIN.INI file:


2. If you experience slow printing, or if you see a long series of repeated
characters (or garbage) appearing in your printed documents, try editing your
CONFIG.SYS file using any text editor (such as the OS/2 System Editor or
Enhanced Editor).  Locate the line BASEDEV=PRINT01.SYS and add the parameter
/IRQ so that the line reads BASEDEV=PRINT01.SYS /IRQ.  Shutdown and restart
your system for the change to take effect.  This change will not affect
printing over a network and it does not apply to Microchannel systems.

3. Make sure that your printer port is properly configured, at the correct
port address for LPT1 (or LPT2, if used), and that your printer port is
generating the correct interrupt (IRQ), and that no other adapter in your PC
is using the same port address or interrupt.  See (4.1) Installation for

4. Make sure that the cable to your printer is properly shielded, grounded,
has all 25 pins wired, and that it does not extend more than 15 feet or 5
meters.  Ideally the cable should be no more than 6 feet or 2 meters in

5. To improve performance when printing from DOS or Windows applications,
configure your application to print to LPT1.OS2 (or LPT2.OS2 for printer port
2).  (WordPerfect for DOS benefits greatly after making this change.)  Use the
application's "print to file" feature, if necessary.  For Windows
applications, use the Win-OS/2 Control Panel to route printer output to

(2.4) COM3 and COM4 Support

 Can I use COM3 and COM4 in OS/2 Warp?

COM3 and COM4 are supported on most PS/2s without any additional effort.  On
ISA, EISA, PCI, and VESA LocalBus machines, some additions are required to
CONFIG.SYS.  Using a text editor, include "(port number, base address,
interrupt number)" parameters next to the COM.SYS filename.  One example:

 DEVICE=C:\OS2\BOOT\COM.SYS (3,3E8,5) (4,2E8,10)

Parameters for COM1 and COM2 need not be included (unless they are somehow
nonstandard).  OS/2 Warp must end up with sequentially numbered logical COM
ports, if possible.  For example, if (physical) port two is not installed but
port three or port four is installed, start numbering using (2,...)  in the
DEVICE lines.  See the OS/2 Warp printed manual and the online Command
Reference for more information.  If these efforts fail, try the SIO drivers
[available from (3.2) Shareware and Freeware Sources].  Note that IRQ 2 is
actually redirected to IRQ 9 on the AT bus, so use (...,...,9) in the above
COM.SYS settings if your serial port is set to use IRQ 2.

AT bus COM ports cannot be used at the same time if they share interrupts
because of bus design limitations (cf.  "Under the Hood:  How Interrupts
Work," Byte, February, 1992).  An adapter which provides more flexibility in
interrupt selection [e.g.  the 16-bit model from STB; see (2.5) Specific
Hardware Recommendations] may prove helpful.  Also, PolyCom, a replacement
driver available from (3.2) Shareware and Freeware Sources, supports up to
eight ports with the right hardware (Xenix-compatible multiport adapters).

"Smart" (coprocessor controlled) multiport communication adapters should be
used when installing more than four ports.  Such an adapter will work with
OS/2 if the manufacturer has written an appropriate driver.  Examples include:

(2.5) Specific Hardware Recommendations

 Are there any specific hardware recommendations?

Here are some of the peripherals and adapters that are particularly well
suited to OS/2 Warp.  Use these recommendations as general guidelines for
adding peripherals to your OS/2 Warp PC.  When you buy a new PC, remember to
ask for OS/2 Warp preloaded.  When you purchase a new add-on for your PC,
remember to ask about OS/2 Warp drivers and compatibility.

o Sound cards.  There are many excellent sound cards on the market for OS/2
Warp.  Two of the best are the IBM Audiovation (available for both AT bus and
Microchannel) and the Creative Labs SoundBlaster 16 SCSI-2.  This model
SoundBlaster includes a built-in SCSI port for CD-ROM drives, tape backup
devices, etc., and OS/2 Warp's built-in Adaptec 152x SCSI driver will work
with the card.  OS/2 Warp also includes the correct SoundBlaster audio driver.
An OS/2 Warp driver diskette for the Audiovation adapter is available either
with the card or from the IBM PC Company BBS at 919-517-0001.

o 16550AFN Buffered UART Serial Port Adapters.  Improves high speed serial
communications performance.  Price:  $35 for a two port adapter from Zero-One
Networking (phone 800-255-4101 or 714-693-0808).  Ask about adapters with
parallel ports.

o Four Port 16550AFN Buffered UART Serial Adapter.  The STB 4-COM adapter is
available for $110 delivered by calling 800-735-5266 Ext.  64 (or 919-286-1502
Ext.  40).  The 16-bit STB adapter provides four buffered serial ports, each
with an independently selectable interrupt and address.  IRQs above 7 are
supported for each port.  Up to two of these adapters may be installed in the
same system (for up to eight buffered serial ports).  Four six inch 8-pin DIN
to DB9 male converter cables are supplied.  Fifteen month manufacturer's
warranty and free technical support from STB.

o CD-ROM Drives.  True SCSI-2 CD-ROM drives (double speed or better) are
preferred over other CD-ROM drives.  They are easier to configure, perform
better, and can be easily transferred to another PC (particularly portable,
external drives).  They can also be more easily attached to many notebook
computers.  The SoundBlaster 16 SCSI-2 adapter, mentioned above, can provide
the SCSI port for a CD-ROM drive.

o SuperVGA cards.  A wide variety of SuperVGA cards work well with OS/2 Warp.
Many users find that cards based on the S3 chipsets are among the most
compatible and represent the best values.

o RAM (Memory).  Your first choice when you wish to upgrade your PC to enhance
the performance of OS/2 Warp.  Choose good quality, name brand memory, and
make sure that parity checking is included.  (Some new PCs are attempting to
get by with non-parity RAM.  To ensure that all your memory is operating
correctly, parity checked RAM is preferred.  In fact, many higher end systems,
especially servers, use error correcting memory for reliability.)

o Hard Disk Drives.  For a PC with one or two hard disks, each 512 MB or less
in size, IDE hard disks represent the best value.  They are inexpensive, and
they perform well.  However, SCSI hard disks with a good quality OS/2 Warp
compatible SCSI adapter are generally a better choice when you have more than
one hard disk in your PC and/or you wish to use hard disks larger than about
512 MB in size.  SCSI also provides the opportunity to add tape backup,
CD-ROM, and other devices.  Caching hard disk adapters are generally useful
only after you have added main memory (RAM) to the PC itself.

o Tape Backup Devices.  Cheap tape drives (which attach to your PC's diskette
controller quite often) are quite tempting, and they work well under OS/2 Warp
with backup software such as IBM's DualStor and MSR's BackMaster.  However, a
SCSI tape drive (such as a 4 mm DAT drive) is now only a little more
expensive.  Each 4 mm cartridge can hold 2 GB of data (uncompressed) or more.
With hard disks growing larger and larger, you may wish to invest in a high
capacity tape drive.

o Processor/Motherboard.  If you need to save money, save it by getting a
system with a less powerful processor.  OS/2 Warp will benefit most from
adding main memory (RAM), and generally least from upgrading the processor.
Since OS/2 Warp multitasks so well, the need for raw speed is usually less.
(If you use another operating system, where you spend time waiting for tasks
to complete, and where you cannot put tasks in the background and still get
other work done, you can imagine that a faster processor would be of greater
benefit.)  However, make sure that your PC's motherboard contains an OverDrive
socket, and preferably one that supports symmetric multiprocessing (SMP) and
the Intel MPS 1.1 standard.  That is, a system into which you can place a
second processor chip and have both processors run at the same time.  If you
then run OS/2 for SMP, which supports two or more processors, you have a much
more powerful system should you choose to upgrade.  Also, the more processor
cache memory you can afford in your PC, the better.  However, if you can find
a system which also uses so-called interleaved memory, OS/2 Warp will benefit
tremendously.  Many systems designed as servers use faster interleaved memory.

o Notebook Computers.  The critical factor when choosing a notebook computer
for OS/2 Warp is support for PCMCIA card slots.  Most notebooks are now
supported, but be sure to check ahead of time.  If your notebook computer is
not listed in OS/2 Warp's list of PCMCIA drivers, choose either the closest
match (in terms of manufacturer) or try each, one by one, in turn.  Midwestern
Micro notebooks, for example, appear to work well with OS/2 Warp's AST
PowerExec PCMCIA driver.  Toshiba now preloads OS/2 Warp on its notebooks, on
request, and all IBM Thinkpads will ship with OS/2 Warp preloaded.

o Network Adapters.  Any network adapter with an "IBM LAN Server" or "IBM OS/2
NDIS" driver (usually supplied on a diskette with the card) will work fine
with OS/2 Warp.  Ethernet (especially 10BaseT) is a popular choice for PC
networking.  IBM, 3Com, Cabletron, Intel, and SMC are some of the most popular
brands.  However, many large companies have upgraded their Token Ring networks
to 16 Mbps, so if you are looking for a good value for a small network, 4 Mbps
IBM Token Ring adapters for both AT bus and Microchannel are inexpensive and
thoroughly standardized.  Setting up a small OS/2 Warp network with Artisoft's
LANtastic for OS/2?  Try an IBM MAU (Multistation Access Unit), as many Token
Ring cards as you need (used 4 Mbps cards are under $50), and cables.  Look in
the back pages of LAN Times, The Processor, PC Week, and other publications
which are read by larger corporate computer users, and you'll see great
bargains on good quality networking products.  See (3.8) Networking Products
for some more advice.

(2.6) More Than 16 MB RAM

 Can I use more than 16 MB of RAM?

OS/2 Warp will address all the RAM in your system.  If the BIOS recognizes the
memory, OS/2 Warp will find it and use it.

However, on certain systems the RAM beyond the 16 MB boundary may be used as a
fast swap area.  OS/2 Warp relies on its swap file, SWAPPER.DAT, to hold code
and data which cannot fit into real memory (i.e.  to provide virtual memory).
If the swap file (and applications) can only be accessed via a hard disk
adapter which uses 24-bit DMA for disk access (e.g.  the Adaptec 154x series),
then the system must move code and data below the 16 MB boundary before it can
write it to disk.  This "double move" is costly (in terms of performance), and
often OS/2 Warp will merely use all the RAM above the 16 MB boundary as a fast
swap area (before writing to disk) to avoid the problem.  It is up to the hard
disk adapter driver, however, to decide how to handle this situation.

Only AT bus adapters are limited to 24-bit DMA.  Microchannel, EISA, VESA
LocalBus, and other 32-bit adapters are not so limited.  Moreover, only a
select few AT bus hard disk adapters utilize DMA.  Nearly all MFM, RLL, ESDI,
and IDE adapters, and most SCSI adapters, do not use DMA for disk access.

Suffice it to say that, regardless of your present hardware, OS/2 Warp will
take advantage of it as best it can.  However, if you are planning new
hardware purchases, you may wish to take this particular hardware design
limitation into account.  Specifically, if you plan to install more than 16 MB
of RAM in your system, either choose a 32-bit hard disk adapter (Microchannel
or PCI, for example) or choose an AT bus adapter which does not utilize DMA
for disk access (a standard IDE adapter, an Adaptec 152x series SCSI adapter,
or a Future Domain SCSI adapter, for example).  The performance trade-off is
highly system dependent, however.  You may find that even DMA adapters such as
the Adaptec 154x series outperform the alternatives in certain cases.

(2.7) Device Driver List

 What device drivers are available that aren't included with OS/2 Warp?

Here is a list of a few of the device drivers (and their common filenames)
available from (3.2) Shareware and Freeware Sources.  New and updated OS/2
Warp device drivers are being released almost every day, so use this list only
as a rough guide.  If you do not see the driver you need listed, you may be
able to use one of OS/2 Warp's built-in drivers or a "generic" driver.  If you
develop PC hardware, and wish to create an OS/2 Warp driver, contact the IBM
Developer Connection (800-6-DEVCON in the United States, for example) to
obtain the OS/2 Device Driver Development Kit.

(3.4) Disk Utilities

 Is there a Norton Utilities for OS/2 Warp?

Not yet, although Norton Desktop, Norton Utilities, and Norton Commander all
work under OS/2 Warp's DOS/Windows sessions [with limitations; see (1.3) DOS
and Windows Compatibility].  Also, Norton Commander is now available for OS/2

However, there are at least three sets of system utilities just for OS/2 Warp:
GammaTech Utilities, JFS Utilities, and Graham Utilities.  All are available
from dealers specializing in OS/2 Warp software.  Note that OS/2 Warp has a
built-in UNDELETE command (see the online Command Reference for instructions
on how to enable UNDELETE), and HPFS is resistant to fragmentation [see (1.5)
High Performance File System].

(3.5) Running a BBS Under OS/2 Warp

 I would like to set up an OS/2 Warp BBS.  What is available?

OS/2 Warp is an excellent environment for BBS operation (even using
DOS/Windows software), including large multiline facilities.  Related software
will enable FidoNet capabilities, gateways to Usenet/UUCP, nodelist
processing, additional file transfer protocols, and more.

Six popular OS/2 Warp BBSes are Maximus, Lora, and Simplex [available from
(3.2) Shareware and Freeware Sources), Omega Point/2 (BBS 404-564-1961),
Magnum (phone 818-706-9800, BBS 818-706-9805), and Multi-Net (phone
503-883-8099, BBS 503-883-8197).

For more information on operating a BBS under OS/2 Warp (with conferences
devoted to the subject) log on to one of the OS/2 Warp BBSes listed in (4.11)
OS/2 Warp BBSes.

(3.6) Multimedia (MMPM/2)

 What do I need for OS/2 Warp multimedia applications?

OS/2 Warp includes support for both the Windows multimedia extensions and
MMPM/2, the OS/2 Warp multimedia extensions, at no extra charge.  OS/2 Warp's
MMPM/2 includes software motion video support for IBM Ultimotion, Intel Indeo,
and Autodesk FLI/FLC files.  Software motion video provides playback of video
clips in a window under OS/2 Warp.  (Video for Windows will operate correctly
under Win-OS/2, but Ultimotion is far more capable than Video for Windows.
Ultimotion supports higher frame rates, larger image sizes, better
synchronization of video and audio, stretching, and, often, simultaneous
playback of two or more video clips, even with background tasks running.)  An
accelerated display adapter and a fast processor can help improve the quality
of software motion video.

Drivers for the following multimedia adapters (audio, video capture, video
display, MPEG, etc.)  are included with OS/2 Warp:

  o AITech WaveWatcher
  o AudioDrive (ESS 688)
  o Business Audio (AD1848)
  o CEI Video Clipper
  o Compaq Business Audio
  o Creative Labs SoundBlaster
  o Creative Labs SoundBlaster 16
  o Creative Labs SoundBlaster AWE32
  o Creative Labs SoundBlaster Pro
  o Creative Labs VideoBlaster
  o Hauppauge Win/TV
  o IBM M-Audio
  o IBM Thinkpad Audio (Crystal)
  o MediaVision Jazz 16
  o MediaVision ProAudio Spectrum 16
  o New Media Graphics Super VideoWindows
  o OmniComp M&M Basic
  o Samsung VideoMagic
  o Sigma Designs Reel Magic
  o Sound Galaxy NOVA 16 Extra
  o Toshiba 4700C
  o Toshiba 6600C

If you have an audio card that is not on this list, it may still work with a
similar driver.  For example, the MediaVision ProAudio Studio and ProAudio
Spectrum Plus (see below) sound cards will work with the ProAudio Spectrum 16
driver.  Also, many ATI sound cards work with the Creative Labs SoundBlaster
or SoundBlaster Pro driver.  Some ATI sound cards, however, require a BIOS

Other drivers (including one for the popular Gravis Ultrasound) are available
either from the manufacturer of your sound card or from (3.2) Shareware and
Freeware Sources.

If you do not have a sound card, there is a MMPM/2 driver for the standard PC
speaker, also available from OS/2 Warp shareware and freeware sources.
However, this driver demands a huge amount of processor attention and does not
provide sound quality that even approaches the simplest sound card.

Note that the MediaVision ProAudio Spectrum Plus operates correctly when using
the built-in MMPM/2 ProAudio Spectrum 16 driver.  However, to obtain full
functionality you must change the PARAMSTRING line in the [ibmwavepas1601]
section of the file \MMOS2\MMPM2.INI after installation of MMPM/2.  Using a
text editor (like the OS/2 System Editor), change the line so that BPS=8
instead of BPS=16.  This change causes MMPM/2 to default to 8-bit audio (since
the ProAudio Spectrum Plus does not support 16-bit audio).

REXX programs [see (5.11) REXX] can be used to play, record, and manipulate
MMPM/2 audio and video files.  For more information on REXX and MMPM/2,
consult the online Multimedia with REXX document (located in the Multimedia

More information on IBM's OS/2 Warp multimedia extensions (MMPM/2) and tools,
Ultimotion, multimedia hardware, and IBM multimedia titles (e.g.  Illuminated
Manuscript) is available through IBM's Multimedia Office (phone 800-426-9402
ext.  150).

Support for DOS and Windows applications which require access to a sound card
will depend on which sound card you have.  Generally such applications will
work fine.  At the worst you may have to turn off MMPM/2 support and/or run
only one DOS or Windows application which requires use of the sound card at a
time.  At best you can run DOS, Windows, and OS/2 applications which use the
sound card at the same time.  For advice on setting up DOS, Windows, and OS/2
multimedia applications, consult the Multimedia online document, located in
your Information folder.

(3.7) Viruses

 Should I worry about viruses when running OS/2 Warp?

At present there are no viruses specific to OS/2 Warp.  However, DOS/Windows
viruses can conceivably infect an OS/2 Warp system.  DOS/Windows antivirus
tools are just as useful in preventing such infection.  Also, IBM has an
antivirus package (AntiVirus/2) which runs under OS/2 Warp directly (without
using a DOS or Windows session).  To order AntiVirus/2, call 800-551-3579
(800-465-7999 in Canada).  Other antivirus packages for OS/2 Warp include
Central Point's AntiVirus, McAfee's SCAN and CLEAN, and Dr.  Solomon's
Antivirus Toolkit, Dr.  Cohen, and F-PROT.

But OS/2 Warp is likely to be much more resistant to viruses because of its
design.  Viruses running in one virtual DOS/Windows session are likely to be
confined to that session.  Low level disk access is curtailed under OS/2 Warp,
thus preventing most virus infection at that level.  And when a DOS/Windows
virus does trigger, it is far less likely to disrupt the entire system.  In
fact, OS/2 Warp is most vulnerable when it isn't in charge (i.e.  when native
DOS is being used).  A DOS virus then has free reign to write to the hard disk
and possibly disable OS/2 Warp.  The greater risk comes from leaving OS/2

OS/2 Warp is by no means virus proof -- no system is.  But it should prove
more resistant to virus infection.

(3.8) Networking Products

 What networking products are available for OS/2 Warp?

Unfortunately, PC networking can be a complicated subject.  The simple act of
connecting two PCs can be easy, though, if you understand a little bit about
how networks operate (and how they relate to OS/2 Warp).  With that caveat in
mind, here is a plain English introduction to networking with OS/2 Warp.

 Drivers for Network Adapters

OS/2 Warp drivers are available for nearly all network adapters because of
OS/2's dominant position as the software of choice for PC networking.  There
are two types of OS/2 Warp network drivers in general use:  NDIS and ODI.  ODI
is only used by the Novell Netware Client Kit for OS/2.  NDIS drivers are used
for all other OS/2 networking software in common use.

If you only wish to connect your OS/2 Warp PC to Novell Netware servers using
the Novell Netware Client Kit for OS/2, then you should use an OS/2 ODI
network card driver.  The driver will likely be supplied with the Novell
Netware Client Kit for OS/2 (see below).

If you do not plan to run the Novell Netware Client Kit for OS/2, or you plan
to run it in combination with other OS/2 networking or communications
software, you should plan on using the OS/2 NDIS (also sometimes known as the
IBM LAN Server) driver for your network card.  The OS/2 NDIS driver is almost
always found on a diskette accompanying your network card or can be obtained
directly from the manufacturer.  It may also be included in the OS/2
networking software you purchase (for example, IBM LAN Server 4 or Artisoft's
LANtastic for OS/2).  OS/2 NDIS drivers for many network adapters are also
available from (3.2) Shareware and Freeware Sources, as well as
via Internet anonymous ftp.  Drivers for 3Com adapters are available via
anonymous ftp from, from the 3Com Support BBS, or from CompuServe
(GO THREECOM).  Drivers for Cabletron adapters are available via anonymous ftp

Make sure you request the driver intended for OS/2 Version 2.0 or later.  OS/2
NDIS drivers written for earlier releases of OS/2 can be used, but they will
require that you edit the accompanying .NIF file so that more recent
installation programs will recognize it.

The Novell Netware Client Kit for OS/2 can use OS/2 NDIS drivers if you
install an ODI to NDIS converter.  This converter (or "shim") is supplied as
part of either IBM's Network Transport Services/2 (LAPS) or the replacement
product, IBM Multiprotocol Transport Services (MPTS/LAPS).  (NTS/2 should be
considered an earlier version of MPTS.)  MPTS forms the core of all OS/2 Warp
networking software.  It provides the installation and configuration utility
for matching network card drivers with networking protocols.  IBM licenses
MPTS to many vendors, and it is included with most OS/2 networking products.
MPTS is almost always the first software you should install (after OS/2 Warp)
to allow your PC to access a network.  Using MPTS, you simply select your
network card(s), then select which networking protocol(s) you wish to run with
your network card(s), and MPTS takes care of the rest.

 What Networking Protocols are Available?

There are few (if any) networking protocols which are not available for OS/2
Warp.  A networking protocol is simply the language used for communicating
with other systems across the network.  OS/2 Warp allows you to use multiple
networking protocols, at the same time, over the same network card, should you
need to, so you can mix and match as need be (without taking away precious
memory from your DOS applications).  Sometimes networking protocols are
available by themselves ( packaged without any client software to take
advantage of the protocol).  For example, the IBM LAN Server 4 requester
(client) software includes all the programs you need to access a server (or
peer) running IBM LAN Server 4. It also includes MPTS with NetBIOS (the
primary protocol used for communicating with systems running LAN Server,
Windows for Workgroups, and NT, among others).  However, the same MPTS
includes other protocol support, including TCP/IP, 802.2 (SNA/APPN), and the
ODI to NDIS converter (used to run the Novell NetWare Client Kit for OS/2).
Other times OS/2 networking software comes with everything you need in one
box.  Still other times the software which uses a particular networking
protocol is packaged separate from MPTS and the protocol support.  For
example, the Internet Connection, part of OS/2 Warp's BonusPak, works only
with a modem using a dial-up connection to the Internet unless you add MPTS
(which provides TCP/IP protocol support for network cards).

There are four primary networking protocols for PCs in use today.  If you are
just starting to venture into the world of PC networking, you need not
understand everything about these protocols, but you should know what popular
OS/2 Warp networking software uses each.

  o TCP/IP (Transmission Control Protocol/Internet Protocol)

As the name suggests, TCP/IP is the predominant protocol used for connecting
systems into the Internet.  Due to the popularity of the Internet, and due to
the fact that TCP/IP is available for a larger variety of systems than any
other networking protocol, TCP/IP use is growing rapidly.  TCP/IP is designed
to be routed over wide area networks, so it is well suited for campus
environments and for connecting many remote locations.  However, TCP/IP has
several disadvantages.  It can be difficult to configure (although OS/2 Warp's
TCP/IP support is the easiest yet devised).  It treats all network traffic the
same, regardless of its importance.  It is not very efficient handling
exceptionally busy network links.  It cannot guarantee delivery of real time
information (and thus doesn't work particularly well with audio and video).
Finally, NFS (Network File System), the software used to share disks over a
TCP/IP-based network, lacks features and performance.

The following software packages for OS/2 Warp provide TCP/IP protocol support
for network adapters (in other words, they include MPTS):

     - IBM DCE Client Kit for OS/2
     - IBM LAN Server 4
     - IBM LAN Server 4 Requester (Client) for OS/2 (comes with LAN Server 4)
     - IBM AnyNet/2
     - Most other products with MPTS

The following software packages for OS/2 Warp provide TCP/IP protocol support
plus TCP/IP access software beyond that included with OS/2 Warp:

     - IBM TCP/IP Version 2 for OS/2 Base Services Kit (requires latest Service

Includes both client and server software, including telnetd, ftpd, rshd,
rexecd, and more.

     - IBM TCP/IP Version 2 for OS/2 Accessory Kits (require latest Service Paks)

Add-on kits are available for NFS (server and client), X Window Server, Domain
Name Server, X.25 Extended Networking, and more.

Other protocols (such as NetBIOS) can be encapsulated and routed over TCP/IP.
(MPTS provides the support to do so.)  WinSock support is provided with OS/2
Warp's Internet Connection software, so you can run any TCP/IP or Internet
software designed for Windows under OS/2 Warp.  See (0.4) Special Report on
OS/2 Warp for additional information on TCP/IP, the Internet, and OS/2 Warp.


NetBIOS is the "native" protocol used by IBM LAN Server, Artisoft's LANtastic
(Version 5 and later, including LANtastic for OS/2), Windows for Workgroups,
Microsoft Windows NT, Microsoft LAN Manager, and several other PC-based
network software packages.  The protocol is fairly well standardized, and all
these systems can "talk" to one another.  NetBIOS is the highest performance
networking protocol available for PCs (or, more precisely, IBM LAN Server 4
Advanced has been rated the fastest PC network server by LANQuest Labs when
compared with Microsoft NT Advanced Server, which uses NetBIOS, and Novell
Netware, which uses the IPX protocol).  However, its major disadvantage is
that it cannot be easily routed over wide area networks (see above).

The following software packages for OS/2 Warp provide NetBIOS protocol support
for network adapters:

     - IBM LAN Distance
     - IBM Network Transport Services/2
     - IBM Communications Manager (Version 1.1 or later)
     - Most other products with LAPS
     - IBM DCE Client Kit for OS/2
     - IBM AnyNet/2
     - Most other products with MPTS

The following software packages for OS/2 Warp provide NetBIOS protocol support
for your network card plus access software for sharing disks, printers, etc.,
over a NetBIOS-based network:

     - Artisoft's LANtastic for OS/2

The premier peer-to-peer networking package for OS/2 Warp.  Quickly, easily,
and inexpensively connects you to other OS/2 Warp PCs with LANtastic or IBM
LAN Server, and Microsoft Windows for Workgroups and NT PCs.  LAN Times raves
that LANtastic for OS/2 is much easier to use than any other version.

     - IBM LAN Server 4

Rated the fastest network operating system by LANQuest Labs.  Available in
both Entry and Advanced versions, and second only to Novell Netware in
marketshare, IBM LAN Server 4 now includes both TCP/IP and NetBIOS protocol
support, drag-and-drop administration, better documentation, and a host of
other enhancements.  Winner of "Best of Show" at Networld+Interop.

     - IBM LAN Server 4 Requester (Client) for OS/2

Offers connection to any NetBIOS-based server, even using NetBIOS over TCP/IP.
Also offers limited peer-to-peer networking.  Diskettes containing this
software are included with IBM LAN Server 4 only.

In short, for small peer-to-peer networks, Artisoft's LANtastic for OS/2 is an
excellent choice.  When your needs grow, IBM LAN Server 4 Entry Edition fits
the bill.  And, when your needs require the fastest PC server you can get, IBM
LAN Server 4 Advanced Edition is the wise move.


IPX is a protocol which was designed by Novell.  It is used to connect to
Novell Netware servers and to PCs running Personal Netware.

The following software packages for OS/2 Warp provide IPX protocol support and
Netware access software for your network card:

     - Novell Netware Client Kit for OS/2

Updated regularly (the latest version is Release 2.11), the Netware Kit for
OS/2 is freely available from Compuserve, OS/2 Warp BBSes, and many other
electronic sources.  (Novell collects revenue from higher priced servers and
provides free or nearly free client software.)  To use the Netware Kit with
OS/2 NDIS drivers (and other OS/2 Warp networking software), be sure to select
Netware support when you configure your network card using MPTS.  If you only
plan to use your network card to access Novell Netware servers, you can use an
OS/2 ODI driver (if available).

     - Novell Netware for OS/2 (from IBM)

A kit which allows you to install the regular Novell Netware 4.01 server
software on an OS/2 PC.  Your complete Netware server can then run alongside
any other DOS, Windows, or OS/2 applications, even IBM LAN Server 4, on the
same PC.

  o 802.2/SNA

IBM's enterprise networking protocols are collectively referred to as SNA
(Systems Networking Architecture).  These are the protocols used to connect
PCs to other PCs, midrange systems (such as the AS/400), and mainframe systems
(such as the ES/9000).  SNA protocols are similar to TCP/IP in that they are
being used to connect a variety of different systems together.  However, SNA
protocols offer features such as rollback/commit options (for keeping
databases in sync), priority markers (for giving more important traffic
preference), and better utilization over busy networks.

Communications Manager/2 is a comprehensive package designed for enterprise
networking with SNA protocols using dial-up, ISDN, coax, or network links.
Terminal emulation (IBM 3270, IBM 5250), file transfer (IND$FILE), APPC/APPN,
SDLC, LU 8.2, and more are all included.  In other words, all the access
software you need for taking advantage of IBM's enterprise networking is in
one integrated package.  Communications Manager/2 Version 1.1 (or later)
includes NTS/2 (LAPS).

  What Other Networking Packages are Available for OS/2 Warp?

The four primary protocols are not the only protocols in use today (and they
are not the only protocols which are available for OS/2 Warp).  Other packages

  o DEC Pathworks (DECnet)

  o Banyan Vines Requester (Client) for OS/2

  o AppleTalk (included with Lotus Notes for OS/2)

  o IBM LAN Server for Macintosh

Designed to run alongside a PC running IBM LAN Server 4, LAN Server for
Macintosh allows the same server to be accessed by Apple Macintoshes on the
network.  It makes an IBM LAN Server 4 system look like an AppleShare server.

In addition, there are many other software packages designed for networks
which are also designed for OS/2 Warp.  Some are servers (Lotus Notes, cc:Mail
Post Office for OS/2, and database servers such as IBM DB2 for OS/2 and Sybase
System 10 SQL Server).  Some are gateways and middleware (for example, IBM LAN
Distance, which provides secure dial-up access to your office network; your
modem behaves just like a network card, up to the speed of your modem).  Some
help manage networks (like IBM Netview for OS/2, IBM NetFinity, and
CA-Unicenter from Computer Associates).  Some let you control a PC over the
network (IBM DCAF, Hilgraeve's KopyKat, and SCA's Poly/PM, for example).  Some
automate backups over a network (IBM ADSM).  Some check for viruses (IBM
Antivirus/2, McAfee ViruScan for OS/2).  Some help you install software over a
network (IBM LAD/2, IBM NetView Distribution Manager).  And some just simply
don't fit into any neat category (including Global Village's Faxworks LAN, IBM
DCE, IBM SOM Toolkit, and IBM Time and Place/2).  By no means is this a
comprehensive list.  And these software packages aren't reinventing the wheel;
they all use one (or more) of the above mentioned networking protocols to
communicate.  So, for example, you might choose Artisoft's LANtastic for OS/2
and the Lotus Smartsuite for OS/2 (which includes cc:Mail for OS/2) to set up
a small PC network with electronic mail, since cc:Mail works fine with

Suffice it to say that OS/2 Warp is the most connected PC operating system,
and it connects with style.  Infoworld, in fact, calls OS/2 the best network
client (and awarded it the "Interoperability Award").

(3.9) Peer-to-Peer Networking

 How do I connect an OS/2 Warp machine into a peer-to-peer network?

There are three preferred packages for connecting your OS/2 Warp PC into a
peer-to-peer network:

  o Artisoft's LANtastic for OS/2

Simplest, easiest, and least expensive.  Rated 4.5 (out of a possible 5
points) by LAN Times.  Connects with other LANtastic PCs (DOS, Windows, and
OS/2), IBM LAN Server, Microsoft LAN Manager, Windows for Workgroups, and
Windows NT.

  o IBM TCP/IP Version 2 for OS/2 with NFS Kit

NFS (Network File System) is the standard way to share disks with other
systems across a TCP/IP network (including the Internet).  The IBM NFS Kit
turns any OS/2 Warp PC into an NFS client and server.  If you want to
participate in a peer-to-peer network with many Unix-based workstations
(including IBM's RS/6000s), this choice is best.  If you have TCP/IP protocol
support from some other networking product (such as one which includes MPTS),
the IBM TCP/IP Version 2 for OS/2 Base Services Kit is not absolutely

  o IBM Communications Manager/2

APPN/APPC protocols for peer-to-peer networking are provided in this
comprehensive package for IBM enterprise networking with SNA.  Your OS/2 Warp
PC is a full peer with midrange systems (such as the IBM AS/400) and
mainframes (such as the IBM ES/9000).  If these acronyms are foreign to you,
try LANtastic for OS/2.

(3.10) Extended Services

 What is Extended Services?

Prior to Version 2.0, IBM offered two separate packages with each release of
OS/2:  Standard Edition and Extended Edition.  Extended Edition included
extra, bundled software products:  the Communications Manager (for
communication with IBM mainframes, minicomputers, and other hosts), Database
Manager (a full, network aware, relational database), and LAN Requester.

Later, IBM unbundled the Extended Edition features, dropped LAN Requester from
the package (now available separately, with IBM's LAN Server), updated it for
OS/2 2.x, and renamed it Extended Services 1.0.  ES, by itself, did not
include the base operating system as Extended Edition once did.

Most recently, IBM has stopped selling Extended Services, splitting it up into
DB2 for OS/2 (a full 32-bit relational database) and Communications Manager/2.
With each component available "a la carte," you can configure your OS/2 Warp
system to your exact specifications (almost always at a lower cost), and you
are free to substitute similar products from other vendors (so you aren't
locked into IBM's offerings).

To install the now obsolete Extended Services 1.0 under OS/2 2.1 or later, you
must replace the ESSTART.CMD file on ES Diskette 1 with the ESSTART.BAK file
found in the \OS2\INSTALL directory.  Remember to keep a backup of the old

(3.11) Internet Connection

 How do I connect my OS/2 Warp PC to the Internet?

The following information is adapted from a chapter appearing in the
forthcoming book Internet Secrets from IDG Books, a comprehensive guide to the

IBM's flagship software for PCs, OS/2 Warp, ships with a BonusPak of full
fledged 32-bit applications, including a suite of Internet access
applications.  This section describes those capabilities, why you might choose
OS/2 Warp to connect to the Internet, and how to configure and customize some
of the special features found in the OS/2 Warp Internet Connection.

 What is OS/2 Warp's Internet Connection?

The Internet Connection supplied with the basic OS/2 Warp package provides
everything you need to access the Internet using a direct dial-up SLIP or PPP
connection.  There are two modem dialers supplied with the package.  One
registers you with the IBM Global Network (currently the only worldwide
dial-up Internet service provider) and the other lets you sign onto any third
party provider of your choice.  Three free hours of Internet access on the IBM
Global Network are provided with every copy of OS/2 Warp.

OS/2 Warp's BonusPak also includes Person to Person, Video IN, Multimedia
Viewer, and other applications which enhance the capabilities of the Internet
Connection software.  Person to Person allows you to engage in "conference
calls" on your PC, where you can exchange information using a shared
chalkboard and even broadcast video signals if you have a high speed
connection and the necessary hardware.  Whatever you copy into your chalkboard
(such as a Lotus 1-2-3 spreadsheet) is seen by others in your Person to Person
conference.  Participants can draw lines, add text, point to items, and
annotate inside the shared chalkboard window.  Person to Person works over
many types of networks, including the Internet Connection.  Video IN allows
you to record video clips from a VCR, laserdisc player, or other video signal
using any of several video capture adapters for your PC.  However, even if you
do not have a video capture card, you can use OS/2 Warp's Video IN to create
animated weather sequences, for example, like those you see on television as
part of the weather forecast.  You can use the Internet Connection to download
weather maps of your favorite part of the world, then assemble those weather
maps into a movie using Video IN.  Multimedia Viewer extends OS/2 Warp's
multimedia capabilities so that you can view and collect several image types
(such as Kodak Photo CD, TIFF, GIF, Targa, and others) as well as play back
audio files from other systems (such as the Sun .AU format), file types which
are common on the Internet.

OS/2 Warp has several key benefits, all by itself, which make it a powerful
platform for accessing the Internet.  One of OS/2's key strengths for years
has been its ability to reliably handle communications (including modem
traffic) in the background along with other tasks.  OS/2 Warp provides true
preemptive multitasking and multithreading (often called "real multitasking").
Other operating environments, including Microsoft Windows and Macintosh System
7, provide cooperative multitasking.  The difference is that OS/2 Warp, and
not individual applications, is in charge of your PC's processor.  In a
cooperative multitasking system, if one programmer writes one application
which does not yield control of your PC's processor back to the operating
system in timely fashion, everything else stops running.  Unfortunately that
failure happens all too often.  With OS/2 Warp, you can reliably and
confidently download a file from the Internet using ftp, browse the World Wide
Web using the IBM Web Explorer, format a diskette, print a document using your
favorite word processor, and still run other DOS, Windows, and OS/2
applications.  File transfers will not abort, and connections won't be
dropped, simply because you try to go do something else.

With OS/2 Warp, you are encouraged to go spend your time doing other things
while receiving information from the Internet (or doing anything else, for
that matter).  That capability allows you to save a lot of online time (and
charges), because you can have several tasks running at once.  (Many OS/2 Warp
users, for example, run two or more copies of the IBM Web Explorer
simultaneously.  While one is retrieving a page from the World Wide Web, the
other can be read, without in any way disturbing any other task.)  Preemptive
multitasking also means that OS/2 Warp can be used just as easily as a server,
delivering information over the Internet as requested.  OS/2 Warp systems are
used as ftp, gopher, and even World Wide Web servers, for example.

Finally, many "Internet in a Box" packages are sold in software dealerships,
often for $100 or more.  The entire OS/2 Warp package, including the BonusPak
with the Internet Connection, is typically priced at $79 or less.  The user
community for OS/2 Warp is active, enthusiastic, and fast growing, and you can
get help, advice, and assistance from members of that community through the
Internet, even on a real time basis.


The Internet Connection (and other BonusPak applications) comes on a separate
set of diskettes (or CD-ROM) in the OS/2 Warp package.  Inside the BonusPak
box you'll find a brief manual explaining each of the BonusPak applications
and how to install them.  A common installation program is provided
(INSTALL.CMD) which you should ordinarily use.  Select those applications you
wish to install, one-by-one, from the common installation program.

If you have the CD-ROM version of the OS/2 Warp BonusPak, be sure to select
the correct version for the country where you live.  The BonusPak CD-ROM
contains directories (such as US for United States and NO for Norway) for the
various countries of the world.  Run INSTALL.CMD from the correct directory.

Note that you do not have to shutdown and reboot your PC until after you have
installed all the BonusPak applications you wish to use, after you have exited
the common installation program.  You do not need to reboot after installing
each single application.

To shutdown your OS/2 Warp PC, either:

1. Move the mouse pointer so that it is pointing anywhere on the desktop
background.  Tap the right (second) mouse button.  Select Shutdown.  Or,

2. Click on the Shutdown button (can also be a little picture of a PC with a
moon on the screen) located on the LaunchPad.

A proper shutdown will assure that all the changes you have made to your
desktop will be saved.

  Registering with the IBM Global Network

Even if you plan to use a third party Internet provider, you should register
with the IBM Global Network to use your three hours of free time.  The
Internet Connection software is designed to be upgraded over a modem, and the
IBM Global Network will automatically update your OS/2 Warp Internet
Connection to the latest version when you first sign on.  Plus, you can
download the IBM Web Explorer (a free World Wide Web browser for OS/2 Warp) by
double clicking on the Retrieve Software Updates icon, located in your IBM
Internet Connection for OS/2 folder.  If for some reason you do not wish to
sign onto the IBM Global Network, you can retrieve the latest version of the
Internet Connection software and the Web Explorer via anonymous ftp from

The latest rate information for your country is provided when you sign on to
the IBM Global Network.  When the rates are displayed, you are given the
opportunity to then proceed with sign on or abort.  Generally speaking, IBM
Global Network's rates are attractive if you either travel from place to place
(and need local access to the Internet from two or more cities, especially
abroad) or if you must dial long distance (and incur extra charges) to dial
another Internet service provider.  If you live in a major metropolitan area,
well served by other Internet service providers, and you rarely (if ever) need
access to the Internet from other cities, you might want to investigate other
providers (which may be less expensive).

After you have installed the Internet Connection and restarted your OS/2 Warp
PC, you should see a folder called IBM Information Superhighway on your
desktop.  Double click on this folder to open it, then double click on the IBM
Internet Connection for OS/2 folder.  Inside you will see a folder called IBM
Internet Customer Services.  Double click on this folder, then double click on
the Registration icon located inside.  Follow the instructions provided to
sign on.  Make sure your modem is turned on and working.  If you do not know
which type of modem you have, just choose Default.  Make sure you select the
correct speed for your modem.  A V.32bis modem, for example, usually will work
best set to 19,200 bps.

If you ever need help accessing the IBM Global Network, double click on the
Customer Assistance icon (located inside the IBM Internet Customer Services
folder), and click on the Ask for help button.  Telephone numbers and other
ways of reaching IBM Global Network support worldwide are provided.

Be sure to write down your account information (especially your password).
You will need your password every time you wish to sign on to the IBM Global
Network to access the Internet.  You can sign on to the IBM Global Network
using the IBM Internet Dialer program (in your IBM Internet Connection for
OS/2 folder) or by double clicking on any of the available applications (such
as Gopher).

You can modify the settings for your modem, local access number, and other
settings from the Dialer.  Start the Internet Dialer, then click on the Cancel
button to prevent your modem from dialing.  A second window, which provides
information on the commands send to your modem, will pop up.  Just click on
the settings button, and an OS/2 settings notebook for the Dialer will then
appear.  This settings notebook is a common fixture in OS/2 Warp, and it is
used for altering the properties of virtually any object.  Click on the tabs
of the notebook to switch among categories of settings, and click on the
arrows in the lower right of the notebook to flip pages back and forth.

  Internet Connection Applications

The key Internet applications are included with OS/2 Warp's Internet
Connection.  They include Gopher, NewsReader/2, Ultimedia Mail/2 Lite, telnet,
telnet 3270, and ftp.  (The IBM Web Explorer is available for download using
the Retrieve Software Updates program.)  These applications are
straightforward counterparts to versions for other platforms.  However, there
are some special features unique to OS/2 Warp.


The Internet Connection's NewsReader/2 is a graphical application to access
NNTP (Network News Transport Protocol) Internet news servers.  This
application communicates with the news server over your connection with the
Internet provider to receive messages contained in the 7,000 plus forums found
on the Internet.  Facilities are provided for reading messages, posting or
mailing replies, using your favorite text editor, and even decoding so-called
Rot13 messages, which is an encoding method often used by people who wish to
provide mild protection against accidental reading of a message.  For example,
Rot13 can be used to encode messages which contain information about the plot
in a new movie, including its conclusion, and you as a reader have to go
through the task of directing NewsReader/2 to decode the Rot13 text if you
want the information.

Note:  NewsReader/2 is not a "threaded" newsreader, meaning that it does not
provide total flexibility over following "chains" of messages by subject.
However, you can achieve nearly the same effect by changing NewsReader/2's
settings to sort newsgroups by subject.

Note:  Many Internet messages are intended to be viewed on dumb terminals,
where the characters on a given line can line up exactly with characters
located on lines below.  People often construct elaborate (or not so
elaborate) text "drawings," using vertical bars, dashes, and other characters
to create boxes and other shapes, lines, and pictures.  These features will
not display correctly unless you are using a monospaced (as opposed to
proportionally spaced) typeface.  In NewsReader/2, you can select either the
System VIO or System Monospaced screen fonts (in your choice of sizes) to get
better results when viewing messages that contain these features.

The first time you start NewsReader/2, you will be prompted to obtain the full
list of available newsgroups.  Allow NewsReader/2 to fetch this list, but go
ahead and use some of the other Internet Connection applications while the
list is downloading.

  Ultimedia Mail/2 Lite

This mailer is POP compliant, so you can use it with any Internet service
provider which provides a POP mail server.  It also supports MIME mail, so you
can easily send and receive binary attachments to e-mail (including multimedia
files, Kodak Photo CD images, etc).

The Ultimedia Mail/2 Lite folder contains the various parts of this e-mail
application.  To check whether you have received any electronic mail, simply
double click on the In-basket icon.  After Ultimedia Mail has connected to the
server, any e-mail in your in-box will be displayed with some basic
information (subject, author, etc).  The icon to the left of each piece of
mail may contain a number inside.  If so, it indicates that the message has
not only a text part, but also attachments (such as binary files).  The number
indicates the total number of parts contained in that piece of e-mail (the
main text counts as one part).  Simply double click on a piece of e-mail to
open and read it.  A menu is available for each piece of e-mail.  Simply point
to the piece of e-mail and tap the right (second) mouse button.  You can use
this menu to delete e-mail that you do not wish to read, for example.

Note:  Use the sample e-mail that the IBM Global Network sends you to practice
reading, editing, and deleting Internet electronic mail.

You can save e-mail in folders, collecting related pieces of mail in any
chosen categories.  Mail that you send is automatically saved in its own
folder so that you have a record of correspondence with other people.  To
draft a new piece of e-mail (and send it to someone else), double click on the
New Letter icon.  The main window for composing e-mail will then appear.

Note:  Every time you connect to your Internet service provider, be sure to
check your In-basket.  You will not be automatically notified that you have
e-mail waiting.  However, most POP mail servers will hold your e-mail for long
periods of time, so if you do not remember to check, your mail won't be lost
just because you hang up.

Note:  Ultimedia Mail Lite supports drag-and-drop extensively.  To attach a
file or picture to a new letter, for example, simply drag the file or picture
to the rectangular area to the left of the message entry area.  To save a file
attached to received e-mail, drag out of the rectangular area to the desktop
or a folder.

When you use the IBM Global Network to access the Internet, your e-mail
address is, where "username" is whatever name IBM assigned to
you when you registered.  You can give this Internet address out to other
people, and they can send e-mail to you from anywhere in the world.

  telnet and telnet 3270

The templates for these applications are located in the Application Templates
folder (located in the IBM Internet Connection for OS/2 folder).  To create a
telnet session, for example, simply "tear off" one of the telnet templates and
drag it to any other folder (or to the desktop).  Remember that OS/2 Warp, by
default, uses the second (right) mouse button to drag and drop.  Then fill in
the host information with the name of the system you wish to reach using
telnet.  The telnet 3270 (for accessing mainframe computers across the
Internet) and ftp templates work similarly.  If you don't want to create an
icon for every system you log onto, use the telnet, telnet 3270, and ftp icons
located in the Internet Utilities folder.

You can cut and paste using the Internet Connection's telnet and telnet 3270
applications.  (The telnet 3270 icon is used for accessing IBM mainframe
systems over the Internet.  For example, you can reach the IBM OS/2 BBS
subscription service and other IBMLink services by using telnet 3270 to
connect to  Command line (character mode) versions of
these applications are available as well (from any OS/2 command line, full
screen or windowed).

Note:  The telnet and telnet 3270 applications do not include built-in file
transfer capabilities.  If the system you wish to connect to supports it,
simply open another window and use ftp to transfer files.  However, some
systems will not allow ftp for sending and receiving files (CompuServe, for
example, which is reachable by using telnet to connect to  If
so, you may wish to use the freely available C-Kermit for OS/2 as a
replacement for telnet.  C-Kermit, and many other OS/2 Warp Internet packages,
are available from the ftp sites listed below.


The OS/2 Warp Internet Connection comes with both command line (character
mode) and graphical versions of ftp (file transfer program) for sending and
receiving files from various servers on the Internet.  (Popular ftp servers
for OS/2 software are listed below.)

The graphical version (FTPPM) first presents a window which prompts you for
login information (such as user name and password).  Many servers are
so-called "anonymous" servers (meaning that a user name of "anonymous" will
allow you to log on and retrieve any files located in public directories).
You should, however, still enter your e-mail address as a password.  (Some
anonymous ftp servers even require it.)  Ordinarily you can leave the Account
entry blank; some systems (primarily IBM mainframes) may require it, but most
do not.

The main FTPPM window has two primary sections.  At the top you will see a
view of your own PC's hard disk, and you can navigate through directories and
select files just as you would with most other applications.  In the section
below, you will see a directory listing from the remote ftp server, and you
can navigate through its directories very similarly.

There are two common pitfalls encountered by first time users of FTPPM.  The
most common is forgetting to select the correct file type before transferring
a file.  There are two file types available:  ASCII (plain text) and binary.
The default is ASCII, but the default may not be appropriate depending on the
type of file you are trying to send or receive.  Also, you should remember
that most remote ftp servers are case sensitive (so if you have to type a file
name, be sure the case you type matches its directory listing, letter for
letter).  Finally, be sure that you have indicated where you want files to go
when you download files from remote servers.  Otherwise, FTPPM is likely to
place them in the root directory on your PC's hard disk, and you may not want
them there.


Gopher is supplied with OS/2 Warp and provides the ability to navigate through
a set of servers on the Internet which are all interconnected.  You can double
click on menus and files listed in your Gopher window to navigate across
various Internet servers.  Weather maps, software, library catalogs, and much
more are available.

OS/2's Gopher is quite straightfoward.  You can readily distinguish between
files and submenus by looking at the icons to the left of each menu item.
Submenus are indicated by gopher icons.  If you double click on a submenu, you
will get a window with a new set of options displayed.

Note:  Gopher will, by default, create a new window when your menu selection
takes you to another server.  You can use this fact to speed up your searches,
because you can go back to the original window and select another menu option
to branch off in a different direction.  In fact, as with other applications
on OS/2 Warp, you can use other Gopher windows while one is still downloading
information from a server.  To get a list of all the open Gopher windows,
simply bring up the OS/2 Warp Window List by pressing CTRL-ESC.

  IBM Web Explorer

The IBM Web Explorer is a free, downloadable addition to your Internet
Connection.  You can install it on your system by double clicking on the
Retrieve Software Updates icon.

The Web Explorer, like Mosaic and other browsers, is designed to access the
Internet's World Wide Web.  It is a fully multithreaded browser, meaning that
it can receive multiple incoming streams of information simultaneously.  This
multithreaded design speeds up retrieval of WWW pages.

You can configure the Web Explorer to use practically any external program for
viewing various file types (audio, video, pictures, etc).  However, by default
the Web Explorer will use both internal viewers and (if installed) the
BonusPak's Multimedia Viewer, to handle the wide variety of file types stored
in WWW pages.  Many of these file types are not native to the PC, and the
Multimedia Viewer can convert such files to PC readable formats.  (For
example, Sun .AU audio files are very common, and the Multimedia Viewer
includes support for listening to these audio files.)

Because the World Wide Web is highly graphical, you will get best results by
using the Web Explorer on a display with 256 colors or more.  Also, WWW pages
can be large (and take lots of time to download).  However, there are many
ways you can make your time on the World Wide Web much more efficient using
the Web Explorer.  These tips include:

1. Use two (or more) copies of the Web Explorer simultaneously.  While one is
downloading a page, you can be reading and selecting a link in another.  By
default, OS/2 Warp will not start multiple copies of any object simply by
double clicking on its icon again.  To change this default behavior, simply
point the mouse pointer at the Web Explorer program object, tap the right
(second) mouse button, then select Settings.  The familiar OS/2 settings
notebook will appear.  Click on the Window tab, and change the object open
behavior to open another window.  Close the settings notebook, then double
click on the Web Explorer icon to launch another copy.

2. Use the QuickList feature to save favorite pages you have visited.  The Web
Map feature can help you track where you've been.

3. Save pictures and even entire WWW pages using OS/2 Warp's drag-and-drop
features.  The pictures and other elements in a WWW page, as viewed by the IBM
Web Explorer, are objects.  Using the right (second) mouse button, you can
drag and drop a picture of Barney the Dinosaur, for example, to your OS/2 Warp
desktop or any folder to save it.  You can use this method to rapidly create
an animated weather sequence from weather maps (in tandem with the BonusPak's
Video IN application).  Be careful, though, that you do not violate any
copyright restrictions.

  Resources on the Internet for OS/2 Warp Users

You can receive help, information, tips and techniques, and other assistance
using OS/2 Warp through the Internet.  The OS/2 Warp community on the Internet
is large and friendly.  Here are just some of the places to visit:



  anonymous ftp


  World Wide Web

  Internet Relay Chat (IRC)


  Popular Additions to the Internet Connection

You can retrieve free and low cost software to add to your OS/2 Warp system
from the anonymous ftp sites listed above.  Here are some of the most popular:

  Name           Description

  C-Kermit       Used as a replacement for telnet, providing Kermit file transfer
  NetSuite       A collection of popular Internet applications (ftp, gopher, news
  IRC/2          Internet Relay Chat for OS/2 Warp
  GoServe        An IBM-written Gopher server for OS/2 Warp; takes advantage of
  OS2HTTPD       A World Wide Web server for OS/2 Warp
  P2P-FT         A file transfer capability for OS/2 Warp's Person to Person

More applications are being written and released with each passing month, so
consult the OS/2 newsgroups and ftp sites for the latest.

You can also use any Windows Internet software with OS/2 Warp's Internet
Connection.  The Internet Connection includes WinSock support (using the
WINSOCK.DLL file).  Please be sure, though, that the WINSOCK.DLL file supplied
by the Internet Connection is the only file by that name on your PC's hard

  Using Third Party Dial-Up Internet Providers

You need not use the IBM Global Network to access the Internet with OS/2 Warp.
(However, three hours of free access is free time, and you should use it at
least to get the latest versions of Internet software.)  The Internet
Connection (after using the Retrieve Software Updates program) supports
connections to almost any third party Internet service provider using the
standard SLIP or PPP protocols.  The dialer even supports scripting using
OS/2's built-in REXX programming language, so it can respond to any given
login procedure used by your preferred Internet provider.  (A sample script,
ANNEX.CMD, is provided with the Internet Connection to get you started.
Consult the online help for complete information on how to create such a
script.  In most cases, though, either you will not need a special script or
your Internet service provider of choice has the necessary information you
need to get connected.  Be sure to ask your provider for instructions using
OS/2 Warp to connect.)

The Dial Other Internet Providers icon is located in the Internet Utilities
folder and is the application used (instead of the IBM Internet Dialer) to
access third party providers.  You can place several different providers (and
dial-up access numbers) in the Dial Other...  directory.  Be sure to select
SLIP, CSLIP (SLIP with VJ compression), or PPP protocol, as appropriate.  Once
connected to your Internet provider, all the Internet Connection applications
will operate exactly the same way, provided the numeric Internet addresses for
the various servers required (nameserver, POP mail server, etc.)  are
correctly configured.

  Using OS/2 Warp's Internet Connection with a Network Card

See (0.4) Special Report on OS/2 Warp.

At the time of this writing, IBM has started testing a release of OS/2 Warp
with additional bundled applications (including full support for ethernet,
Token Ring, and other network cards) formerly sold separately.  This so-called
"OS/2 Warp for Networks" is scheduled for release sometime in the first half
of 1995.  The larger BonusPak, with the extra networking software, will be
available as an upgrade for base OS/2 Warp as well.

(3.12) Backup Software

 What backup software is available?

Generally DOS backup programs will work under OS/2 Warp, but they may not
capture some OS/2 data (especially extended attributes) on the hard disk
without the assistance of utilities such as EABackup [see (3.2) Shareware and
Freeware Sources].

OS/2 Warp backup tools are available, notably:

Note that BackMaster now supports portable tape drives designed to attach to a
parallel port, including those made by Colorado/HP, as well as other tape
drives (SCSI and non-SCSI).

Keeping your data and applications safe and secure means that you have a well
rehearsed backup and restore strategy.  This strategy should be tested,
because your backup is only useful if it can be restored.  Make sure that the
OS/2 Warp backup software you choose has the features you need for your backup
strategy and that it supports a wide variety of tape backup systems (including

(3.14) Disk Compression

 What on-the-fly disk compression software is available?

Stacker 4 for OS/2 and DOS (Stac Electronics, phone 619-431-7474), DCF/2
(Proportional Software, phone 303-484-2665), and ZipStream (shareware, Carbon
Based Software) are available for OS/2 Warp.

Stacker provides on-the-fly disk compression for FAT drives only.  The product
provides compression for both DOS and OS/2 in the same package, and it will
convert MS-DOS DoubleSpace, DriveSpace, and PC-DOS 6.x SuperStor/DS disk
compression into Stacker format.

DCF/2 compresses both FAT and HPFS drives.  The DCF/2 container file can even
be located on other devices besides hard disks.

ZipStream is available from (3.2) Shareware and Freeware Sources.  It works
with both FAT and HPFS, and it compresses files individually (without using a
large container file).

(3.16) Image Scanners

 How can I use my scanner with OS/2 Warp?

There are three basic approaches to using your image scanner with OS/2 Warp.
In decreasing order of attractiveness:

1. Buy Native OS/2 Warp Software.  Real 32-bit OS/2 software gives you the
best results, integrates well with other OS/2 applications, and works
reliably.  OS/2 software packages for scanners are now available, including
Applause from Solution Technology (407-241-3210 or FAX 407-997-6518) and
ImpOS2.  (Applause is available in versions for Logitech and HP scanners.)

2. Use Existing DOS/Windows Software (SCSI-based Scanner).  Many scanners for
PCs are attached to SCSI adapters (like those from Adaptec) for which there
are OS/2 .ADD device drivers.  You can use your existing DOS or Windows
scanner software if you follow these steps:

a. Load the OS/2 .ADD driver for your SCSI adapter.  OS/2 Warp will do so
automatically for Adaptec, BusLogic, DPT, IBM, and MediaVision/Trantor SCSI
adapters.  You need a BASEDEV=XYZ.ADD line in your CONFIG.SYS file in order to
load the correct driver, where XYZ.ADD is the name of the OS/2 driver file for
your SCSI adapter.

b. Configure OS/2 Warp for ASPI support.  Make sure that the following two
lines are in your CONFIG.SYS file:


where X is replaced with the drive where OS/2 is installed.

c. Load TWAIN device drivers in a DOS/Windows session and run the software.
Your scanner or scanning software probably came with a device driver for
so-called TWAIN support which is designed to work with ASPI (Adaptec SCSI
Programming Interface).  Since you have just configured OS/2 Warp to provide
ASPI services to your DOS and Windows sessions, you can now load device
drivers (such as TWAIN drivers) and software which uses ASPI.  (Since OS/2
Warp is providing ASPI services, do not attempt to load DOS or Windows SCSI or
ASPI drivers.)  Consult the documentation accompanying your scanner and/or
scanning software for additional advice.

3. Use Existing DOS/Windows Software (non-SCSI Scanner).  If your scanner is
attached to a proprietary adapter (often not a SCSI adapter), you may use a
specific DOS session under OS/2 Warp to load the necessary device drivers
(including a driver for the proprietary adapter) and run your scanning

 I am having trouble installing OS/2 Warp.  What should I do?

First consult the printed manual and other materials accompanying OS/2 Warp.
Make sure your PC meets the system requirements in (2.1) Hardware
Requirements.  And if the following instructions do not help, fall back on
IBM's free technical support (phone 800-992-4777 in the United States).  You
can also use the (4.10) Problem Report Form.  For help with printing, see
(2.3) Printer Support.

 Configuring PC Devices

The most common problems in installing and configuring OS/2 Warp occur because
two or more devices in your PC are sharing interrupts (IRQs), port I/O
addresses, memory address space, or DMA (Direct Memory Access) channels.  Any
system with AT bus slots (even systems with only EISA or PCMCIA slots) can
exhibit configuration problems to at least some degree if the various devices
are not configured properly.  (Microchannel systems are designed to be Plug
and Play and are the only systems which avoid these problems.  OS/2 Warp
supports Plug and Play for PCMCIA, which prevents potential configuration
problems unless you add a docking station with AT bus and/or VESA Localbus
slots.)  Such configuration problems are actually not related to OS/2 Warp in
particular; they are due to the way PC hardware is designed and can affect all
software (see below).

More precisely, if your PC is using any AT bus or VESA Localbus adapters, you
must be extremely careful to configure these cards properly so that no system
resources (including IRQs) are used by more than one device.  Unfortunately
so-called Plug and Play (for AT bus) will not be the answer to configuration
problems, since any AT bus adapter which does not support the Plug and Play
specification (very few do today) can (and often will) come into conflict with
other devices, and even a Plug and Play PC probably will not be able to
determine what resources that "old" card is using.  In short, be careful.

How to configure the devices in your PC will depend on both the device and the
PC.  With Microchannel PCs (designed to be Plug and Play ever since their
introduction), configuration is done entirely in software, automatically,
using a Reference Diskette.  With AT bus cards, DIP (Dual Inline Package)
switches and jumpers are the norm.  However, devices which are built into PCs
with AT bus and/or VESA Localbus slots are sometimes configured using
software, either on diskette or built into the PC's ROM BIOS setup program.

If you do have a PC with AT bus and/or VESA Localbus slots, you should write
down the names of all the devices in your system and the IRQs, I/O addresses,
memory space, and DMA channels that they use.  Create a chart with this
information, and keep it with your PC.  Every time you add or remove a device
(or change a device's configuration), you should record these changes on your
PC's chart.  Use the information below as a guide to get you started, bearing
in mind that PCs do vary, and you will need to confirm each piece of
information.  In OS/2 Warp you can use the RMVIEW command to explore your PC's
use of resources (as seen by OS/2 Warp).  At any OS/2 Warp command line, type
RMVIEW /?  for an explanation of the command's options.

As stated above, there are four kinds of resources which any device in your PC
can use:

o Interrupts (IRQs).  When an event occurs which your PC needs to respond to
(such as clicking a mouse button), a signal (called an interrupt) is sent to
your PC's processor by the interrupt controller.  The interrupt controllers
(there are two) are responsible for monitoring sixteen IRQ lines, numbered 0
to 15.  The first controller responds to IRQs 0 to 7. The second controller
handles 8 to 15.  Only the first controller is actually allowed to "talk" to
your computer's processor.  If the second controller receives an interrupt
(for example, as a result of a network card signalling incoming information),
it signals this event to the first controller by triggering IRQ number 2 and
passing the true IRQ number (8 to 15) to the first controller.

This design is called a "cascade," and it is important to understand because
many adapters which you can install inside your PC claim to use IRQ 2. In
fact, they are actually using IRQ 9. When the AT bus was created (as an
upgrade from the 8-bit slots found in the original IBM PC and PC/XT), this
cascade design was adopted so that IRQs 8 to 15 could be added without a
radical redesign.  Since IRQ 2 was needed so that the first controller could
"listen" to the second, the original IRQ 2 was rewired to IRQ 9. Therefore,
8-bit cards are able to use IRQs 0 to 7 (except 2) and 9. Any 16-bit AT bus
cards are able to use IRQs 0 to 15 (except 2), for a total of 15 possible
interrupts.  Still, the documentation accompanying many adapters suggests that
IRQ 2 can be used when, in fact, IRQ 2 was rewired (as part of the card slot)
to trigger IRQ 9 long ago.

No devices in your PC should ever share IRQs (unless you have a Microchannel
PC, where sharing of these fifteen available IRQs is allowed.)  Most PCs use
the following default IRQ assignments:

     IRQ     Common Use

      0      Timer (Real Time Clock)
      1      Keyboard
      2      Cascade
      3      COM2 (Communications Port 2)
      4      COM1 (Communications Port 1)
      5      LPT2 (Printer Port 2)
      6      Diskette Controller
      7      LPT1 (Printer Port 1)
      8      Math Coprocessor
      9      Available
     10      Available
     11      Available
     12      PS/2 Style Mouse
     13      Available
     14      Hard Disk Controller
     15      Available

"Available" simply means that typically (not always) these IRQs are not
prereserved for particular devices and, if not already taken, may be used by
other adapters.

o Port I/O Addresses.  Most devices in your PC require a range of memory
addresses (usually 8 bytes) located low in the range of possible addresses.
These are called port I/O addreses, and, for shorthand, they are typically
recorded using just one number three digits in length.  For example, COM2
(communications port 2) normally uses the port I/O addresses 02F8 through 02FF
(hexadecimal), but often the documentation for a device which can use a COM2
assignment simply refers to the address range required as 2F8 (sometimes
called a base address, or base I/O address).

Port I/O addresses are locations in memory where your PC's processor can place
information (to be received by a device) or read information (to be retrieved
from a device).  So, for example, one of the available eight port I/O
addresses used by COM2 is used for receiving information from, for example, a
modem.  A second location is used to pass information on to the modem, to be
sent out.  Each device which requires port I/O addresses may not use all eight
available, but, nonetheless, port I/O addresses are reserved in blocks of
eight.  No other device in your PC can share another device's port I/O

Fortunately, conflicts involving port I/O addresses are rare.  To avoid
conflicts, make sure that you record any port I/O address blocks used by any
of the add-in cards inside your PC.  Devices which are built into your PC
(such as your PC's keyboard controller) use standard port I/O addresses which
are well understood by manufacturers of add-in cards, and so add-in cards
cannot be set to use these blocks.  Still, one adapter can conflict with
another if your PC's chart is not recorded carefully.  COM ports use the
following port I/O addresses by default:

     Device      Port I/O Address Block

     COM1        3F8 to 3FF
     COM2        2F8 to 2FF
     COM3        3E8 to 3EF
     COM4        2E8 to 2EF

Some 8514/A compatible video cards (notably those made by ATI) may use port
I/O addresses which are ordinarily reserved for COM3 or COM4.  Reconfigure
COM3 and/or COM4 (if present) to avoid conflicts.  Common add-in devices which
use port I/O addresses include network, SCSI, and sound cards.

o Memory Address Space.  In the PC design, a range of memory addresses
(typically from hexadecimal A000:00 to DFFF:FF) was set aside for the use of
add-in adapters (including video).  Adapters can use banks of memory (of
varying sizes) in this range to allow your PC's processor to run programs from
ROM (Read Only Memory) located on the adapter and to communicate with the
adapter (for example, by placing information into video memory for display on
your PC's screen).  Video cards, SCSI adapters, video capture cards, network
cards, and even sound cards are common users of memory address space in this

o DMA Channels.  DMA (Direct Memory Access) channels are used by devices which
need to access your PC's main memory (RAM) directly, without requiring
attention from your PC's processor.  Using DMA can help increase the
responsiveness of your system, freeing your PC's processor to do other things.
Like IRQs, DMA channels are numbered 0 to 15, but all sixteen are available
(none are cascaded).  DMA channel 2 is normally reserved for the diskette
controller.  Most others are available for use by some SCSI adapters, network
cards, sound cards, video capture cards, tape backup controllers, some CD-ROM
adapters, and other devices.  As with any other PC resource, DMA channels
cannot be shared.  Conflicts can cause your system to stop working.

If you think configuring PCs with AT bus and/or Localbus slots is harder than
it should be, and requires more expertise than should be necessary, you are
probably right.  However, there are solutions (both current and proposed) to
these hardware configuration nightmares.  One has been on the market since
1987, namely Microchannel.  The PCI bus is also configured through software,
automatically, providing Plug and Play.  And OS/2 Warp supports Plug and Play
for PCMCIA.  Some manufacturers and vendors are working on Plug and Play for
the AT bus.  However, these technologies for the older AT bus (and for VESA
Localbus) don't address the core problem, namely systems which have the
capability to accept adapters which are not designed for any Plug and Play
scheme.  Nearly all the AT bus and VESA Localbus adapters on the market today,
not to mention all such adapters purchased over the years, do not support Plug
and Play.  Drop such a card into even the best Plug and Play PC, and suddenly
you are back trying to figure out which devices are using which resources in
order to resolve conflicts.

IBM recommends that, as a consumer, regardless of the software you choose to
run, you purchase a PC with a full understanding of these issues.  If you
choose a PC with Microchannel, PCI, and/or PCMCIA slots exclusively, you will
be buying a system which is much easier to configure, saving you time and
money.  (If these designs mean the PC is more expensive, it may be worth the
higher initial expense to save time and money over the life of the system.)
If you purchase a system with EISA, AT bus, and/or Localbus slots, in order to
make such a system easy to configure with Plug and Play you should demand from
the manufacturer both Plug and Play BIOS (in the system itself) and all Plug
and Play adapters.  The moment an adapter which is not Plug and Play ready is
added to such a system is the moment when your configuration work might begin.

  Other Installation Issues

o Be sure your CMOS setup parameters are set correctly, especially those
relating to floppy drives.  RAM should be given sufficient wait states and
precharge cycles.  Test with cache memory and/or shadow RAM disabled if
necessary.  The AT bus should run at 8 MHz.  For best performance, make sure
all your RAM is set to be cacheable.

o Older Adaptec SCSI adapters may require a free BIOS upgrade to recognize
hard disks larger than 1 GB.  Adaptec can be reached at 800-442-7274 or
408-945-8600.  Some Quantum LPS105AT IDE hard disks require a free ROM update
(to Version 2.6) from the manufacturer to work with OS/2.

o If your AMI keyboard BIOS is below Revision F you may need an update.
Contact Washburn & Assoc.  (phone 716-248-3627) for an inexpensive

o Check to make sure keyboard DIP switches are set correctly.  For example, if
the keyboard is attached to a system with an AT bus it should typically be
switched to "AT" mode.

o "Autoswitching" on non-IBM EGA adapters should be disabled (usually with a
DIP switch or jumper setting).  In rare cases it may be necessary to switch
third party VGA/SuperVGA adapters into 8-bit mode and/or disable "autosense."
See (2.2) SuperVGA Support.

o OS/2 Warp is particularly sensitive to bad RAM or cache memory (often
reflected in TRAP 0002 error messages).  Use a thorough RAM testing utility,
and try not to mix 9-chip and 3-chip SIMM/SIPP memory modules.  When
upgrading, avoid adding RAM which is not rated (in nanoseconds) at least as
fast (i.e.  with an equal or lower number) as the RAM already in the system.

o Allow several minutes for OS/2 Warp to build your desktop (and display
icons) at the end of installation -- take the Tutorial offered to you in the
meantime.  Be sure to take a look at the documents found in the Information
folder, too.

o Try disconnecting any tape backup device if "Cannot find COUNTRY.SYS"
messages are encountered when booting OS/2 Warp.  This error message may also
indicate that OS/2 Warp cannot find its boot drive, usually because of an
improperly loaded or omitted hard disk .ADD device driver.

o An Always IN-2000 SCSI adapter with BIOS 3.06A or 3.20 requires an updated
version from the manufacturer.  A companion 8-pin serial PROM chip may also
need to be updated.  Contact Always at 818-597-9595.  Also ask about
non-IBMINT13.I13 driver support.

o The TI TM4000 notebook may require a BIOS update to run OS/2 Warp; phone
817-771-5856 for help.  Also ask about an OS/2 Warp driver for the QuickPort
trackball.  Before installing OS/2 Warp on this machine, be sure to set
Advanced OS Power off and HDD Motor Timeout Always On in the second page of
the machine's setup screen.

o For the technically advanced user, the following list of TRAP error codes
may help you in addressing OS/2 Warp problems.  Report any such TRAPs to IBM
using the (4.10) Problem Report Form.

(4.2) Installing from Drive B

 I can't install OS/2 Warp from Drive B.  What's wrong?

IBM OS/2 Warp can only be installed starting from Drive A, like DOS (unless
your BIOS supports booting from Drive B).  After booting from Drive A, OS/2
Warp can then be copied from CD-ROM or across a network.  (For more
information on installation across a network, see Remote Installation and
Maintenance, IBM Publication No.  GG24-3780.  Related publications include
Automated Installation for CID Enabled OS/2, IBM Pub.  No.  GG24-3783, and
Automated Installation for CID Enabled Extended Services, LAN Server and
Network Transport Services/2, IBM Pub.  No.  GG24-3781.)  You could open your
machine and swap floppy drive cable connectors, use your system's setup
utility to set the new CMOS parameters, and then install OS/2 Warp from the
"new" Drive A. Sometimes the floppy drive cable connectors will not be the
same.  If so you can obtain an adapter plug.

You may also use IBM's twin "bootstrap" diskette images [see (3.2) Shareware
and Freeware Sources] to boot from a 5.25 inch Drive A and install using 3.5
inch OS/2 diskettes inserted into Drive B. These two diskettes are also
available free of charge from IBM OS/2 Warp Technical Support.  However, this
procedure should only be used if absolutely necessary.

Since an ever increasing number of PC software packages is only available on
3.5 inch diskettes (or CD-ROM), IBM recommends that you take the time now, if
at all possible, to reconfigure your PC so that you have a 3.5 inch Drive A.

(4.3) Hard Disk Partitioning

 What is the best way to partition my hard disk for OS/2 Warp?

There is no single best way to partition your hard disk for OS/2 Warp.  For
some advice on the subject you should consult the printed documentation
accompanying OS/2 Warp.  Opinions vary, even among experts.

 What is partitioning?

Your PC's hard disk is organized into sections called partitions, much like an
apartment building is split into separate units.  Each section or unit can be
used for a different purpose, with different furniture (files) contained
inside.  Like an apartment building, the partition walls can be torn down,
moved, and rebuilt, but usually at great expense and with a lot of disruption.
The furniture (files) must be moved out of the unit (partition) and saved
before remodeling (repartitioning).  When you run out of space inside a
partition, you can either split your furniture (files) among two or more
units, or you can remodel.

With DOS (and with OS/2 Warp) partitioning may not even be a concern because
it may have been done already, automatically.  Quite often your PC arrives
with one hard disk containing just one partition -- the simplest
configuration.  When you install OS/2 Warp, by default it will be copied
alongside DOS (if it exists) to this one partition (Drive C), and you will be
able to switch between plain DOS and OS/2 Warp using DualBoot.  (An icon is
placed in your OS/2 Warp Command Prompts folder which lets you switch to plain
DOS, and the BOOT /OS2 command lets you switch back to OS/2 Warp.  Note that
the BOOT program is located in the \OS2 directory, so you may have to use the
command C:\OS2\BOOT /OS2 so that DOS can find the program.)

However, there are reasons why you may wish to set up separate partitions
and/or repartition your hard disk(s).  In OS/2 Warp, the FDISK utility (or the
Advanced installation program) allows you to repartition.  First some

  Term                          Definition

  Primary Partition             Primary partitions have the following
                                restrictions: (1) DOS can only boot (start)
                                from the first primary partition with a
                                logical drive (Drive C) on the first hard disk
                                in a PC; (2) A maximum of four primary
                                partitions are allowed on each hard disk; (3)
                                Every PC must have at least one primary
                                partition somewhere; (4) A primary partition
                                can contain only zero or one logical drive.

  Extended Partition            The other partition type for DOS and OS/2 Warp,
                                which has none of the restrictions noted

  Logical Drives                Both DOS and OS/2 Warp use drive letters (Drive
                                C, Drive D, etc.) to refer to logical drives.
                                A primary partition contains either none or
                                one logical drive, while extended partitions
                                can contain many logical drives.

  Boot Manager                  A special primary partition, one megabyte in
                                size, which comes with OS/2 Warp and which can
                                be installed by OS/2 Warp. If installed and
                                active, Boot Manager presents a menu when you
                                start up your PC, listing all the available
                                operating systems you have placed on the menu.
                                You can then select any one (such as DOS or
                                OS/2 Warp) from the menu. Boot Manager also
                                features an optional timeout.  Boot Manager
                                is required if you wish to start OS/2 Warp
                                from any drive other than the first primary
                                partition (logical Drive C), and it allows
                                OS/2 Warp to be started from a logical drive
                                in an extended partition.

  Installable Drive             During partitioning, one logical drive must be
                                set as installable (to indicate to the OS/2
                                Warp installation program where OS/2 Warp
                                should be placed).

  Startable Partition           A startable partition is one that should be
                                looked at by your PC as it starts.  If an
                                operating system (or Boot Manager) is found,
                                it will be started and run.  At least one
                                partition must be startable.

These definitions hint at some complexity should you decide you wish to
partition your hard disk(s) in some way other than single, large primary
partition(s).  Remember that repartitioning involves backing up all your
files, partitioning your hard disk as desired, reformatting each logical
drive, and restoring files.  (See below for an exception to this procedure.)
Consequently, because of the work involved, you may opt to avoid
repartitioning anyway.  (It also means that you should think carefully about
how to organize your hard disk(s) so that you avoid work later on.)

  Some Advice

To simplify these decisions, you should keep in mind that, in general,
partitions are meant to be used to separate that which must be separated of
necessity.  The partitioning system was invented to allow your PC to store
multiple operating systems which had different types of file systems (in other
words, different ways of storing files on your hard disk).  DOS uses the
so-called FAT (File Allocation Table) file system, for example.  Unix might
use a Berkeley file system, a completely different way of storing the
information required to manage directories of files.  Because these file
systems might be incompatible, separate areas of the hard disk (partitions)
must be set aside, with one operating system never touching the other's

OS/2 Warp (in its basic package) supports two file systems:  the DOS FAT
scheme and HPFS.  So, as you might expect, if you want both DOS and OS/2 Warp,
and you wish to use HPFS on the same (physical) hard disk, you need two
partitions (one for DOS and its FAT file system, one for HPFS), even though
OS/2 Warp itself could be located on the FAT logical drive.  You want to
choose partition sizes so that each logical drive can handle expected growth
in the number and sizes of new files that are added to each.

That advice suggests (correctly) that you should not impose separate
partitions for other reasons, generally speaking.  For example, never create a
separate logical drive for your OS/2 Warp swap file or print spool files.
Also, it rarely makes sense to create a separate drive to divide application
or program files from data files (for backup purposes, for example).  With
both DOS and OS/2 Warp's file systems, subdirectories should be used for that


There are reasons why you might be forced to create separate partitions
despite tendencies not to.  For example, the DOS FAT file system grows less
and less efficient (from both a performance and storage standpoint) as the
size of a logical drive grows.  Moreover, the FAT file system can only cope
with a maximum partition size of two gigabytes.  Hard disks larger than 2 GB
using the DOS FAT file system must be divided.  Also, on many PCs, because of
BIOS restrictions, your startable (primary) partition must be physically
located entirely below the 1024th cylinder on your hard disk (or, roughly
speaking, it must be no larger than about 511 MB).  When the original IBM PC
was designed and first sold in 1981, hard disks were small, (usually 10 MB or
less in size), expensive (in the thousands of dollars), slow, and relatively
uncommon, so the BIOS built into the system was never designed to boot from
such "enormous" hard disks.  While your first, startable partition (the one
containing DOS and/or OS/2 Warp) must often be located entirely below the
1024th cylinder, another partition can be created which spans this cylinder
and occupies the remainder of the hard disk (HPFS recommended).

  "Ideal" Arrangements

What does all this boil down to?  In a perfect world, starting from scratch,
there are probably two common, "ideal" configurations.  If you wish to use
both DOS and OS/2 Warp on the same PC, and switch between plain DOS and OS/2
Warp easily, you should partition your hard disk as follows:

1. Boot Manager (1 MB);

2. Primary Partition with Drive C, FAT file system, containing DOS (large
enough to contain DOS itself plus all the files which you expect you will need
to get access to when running plain DOS);

3. Extended Partition with one logical Drive D, HPFS, containing OS/2 Warp
(remainder of the hard disk).

If you wish to use OS/2 Warp exclusively, there's probably nothing better

1. Primary Partition with Drive C, HPFS, containing OS/2 Warp (entire hard

Of course, we do not live in a perfect world, and you are probably not
starting from scratch, so, for sheer convenience (or other reasons), your
chosen partitioning scheme will vary.  If you find that the partitioning you
choose does not suit you, the worst that can happen is that you will need to
create a complete backup of all your files and restore those files after
reorganizing your hard disk.  A new software package called Partition Magic
from PowerQuest can ease even this procedure, because it allows both
on-the-fly conversion of FAT to HPFS (keeping files intact, where they are)
and, as long as free space permits, movement of the partition lines (a bit
like a sliding wall in an apartment building).  Regardless, you should have a
backup strategy that preserves all your important information.

  How are drive letters assigned?

A common source of confusion arises with the assignment of drive letters.
Both DOS and OS/2 Warp use drive letters (C, D, etc.)  to refer to logical
drives.  Some applications (including Windows and OS/2 Warp itself) depend on
these drive letters to a great degree, so that if you repartition, and the
drive letter changes (so that the application believes it is located on a
different drive, because a different drive letter was assigned to its drive),
the application may not run correctly (or at all).

OS/2 Warp assigns drive letters in the following order (with some
oversimplification here):

1. A and B are reserved for the first and second diskette drives in the PC,
regardless of whether or not they are actually installed and available.

2. C is assigned to the first logical drive found in an active primary
partition.  In practice, C is assigned to the logical drive containing DOS or,
if installed to a primary partition, the logical drive containing OS/2 Warp.
If C is not assigned to a primary partition's logical drive, and that primary
partition is physically located ahead (in front) of the logical drive which
was assigned C, that primary partition will be totally skipped.  In other
words, if the partitions are as follows:

      a. Boot Manager

      b. Primary Partition (DOS, FAT)

      c. Primary Partition (OS/2 Warp, FAT)

then, when OS/2 Warp is started, the primary partition containing DOS will not
be assigned a drive letter, and the drive containing OS/2 Warp will be
assigned C. When DOS is started from the Boot Manager menu, the drive
containing OS/2 Warp will be assigned D. (This "shift" in drive letters argues
for having only one primary partition when using Boot Manager, or for making
the OS/2 Warp primary partition HPFS, which is skipped by DOS.)

3. The next drive letter(s) (D, E, etc.)  is(are) assigned to the remaining
primary partitions' logical drive(s), in sequence, located on all the hard
disks in the system.

4. The next drive letter(s) is(are) assigned to logical drive(s), in sequence,
in the extended partitions located on all the hard disks in the system.

5. The next drive letter(s) is(are) assigned to other devices connected to the
PC (such as CD-ROM drives).

6. Drive letter(s) can then be assigned (not necessarily in sequence) to
remaining drives, such as network drives.

(4.4) Starting OS/2 Warp from Diskette (and CHKDSK)

 How do I access HPFS partitions on my hard drive without booting from the hard
 drive?  I'm getting error messages now -- how do I "repair" my hard disk?

With IBM OS/2 Warp, insert the Installation Diskette, Shutdown (if necessary),
and reboot.  When prompted insert Diskette 1 and press ENTER.  When prompted,
press the F3 key.  You will be given an OS/2 Warp command line prompt.  From
there you can make necessary changes to your hard disk -- an OS/2 Warp
character mode text editor called TEDIT is provided on the OS/2 Warp
Installation Diskette for such changes.  (Make sure you backup CONFIG.SYS
before making any changes so that you can easily revert to the old version
should things go wrong.)

You may use this diskette boot method to run CHKDSK on your FAT or HPFS
volumes.  After you reach the command line, insert Diskette 2. Do not log to
another drive.  Type CHKDSK X:  /F to repair most kinds of damage to your hard
disk, replacing X with the appropriate drive letter.  OS/2 Warp CHKDSK will
also mark your hard disk as accessible, if possible, should OS/2 Warp "lock it
out" for some reason.  It will also allow Workplace Shell drive objects to
open properly if they are not functioning correctly.  Repeat for each drive
letter you wish to check and/or correct.

"Errors" may be reported by CHKDSK if OS/2 Warp was booted from the hard disk.
These "errors" are normal.  Since the hard drive is in use by OS/2 Warp itself
(and files are open) CHKDSK is unable to accurately report errors.

The best way to avoid the need to perform CHKDSK is to always select Shutdown
before turning off your PC.  Click on the Workplace Shell desktop background
using mouse button two to bring up the appropriate menu.  Also, avoid
manipulating OS/2-related files when using native DOS.  Finally, enable
autochecking for all your hard disk volumes.  For HPFS volumes use the
/AUTOCHECK parameter in the IFS=...HPFS line in your CONFIG.SYS.  For FAT
volumes use the AC parameter in the DISKCACHE line of your CONFIG.SYS.  See
the online Command Reference for details.

The Create Utility Diskettes program, located in the OS/2 Warp System Setup
folder, is designed to create a set of three diskettes which can be used to
get to an OS/2 Warp command line prompt (and to provide the essential
utilities often used when booting OS/2 Warp from diskette, including FDISK and
TEDIT).  If for some reason you cannot boot OS/2 Warp from the hard disk,
these diskettes are handy for conducting emergency repairs.

(4.6) Corrective Service Diskettes

 What are CSDs, how do I tell which I have, and where do I get them?

CSDs are Corrective Service Diskettes, or bug fixes (Service Paks),
periodically issued by IBM.  The OS/2 Warp CSD level number may be obtained
using the command SYSLEVEL from an OS/2 Warp command line prompt.  CSDs are
cumulative, i.e.  only the most recent CSD is required to bring a system up
from any previous CSD level.  However, CSDs only apply within a major version
number.  For example, an upgrade, not a CSD, would bring OS/2 Version 2.1 up
to Version 3. Note also that each national language (e.g.  French, U.K.
English) uses a distinct CSD.

CSDs may be ordered by phoning 800-494-3044.  Customers with IBM customer
numbers (usually large sites) should order through IBMLink.  Outside the
United States, ask an authorized IBM dealer or representative for the CSD.
CSDs may also be downloaded from the IBM PC Co.  BBS (modem 919-517-0001),
CompuServe (GO IBMOS2), or from (3.2) Shareware and Freeware Sources.  And
CSDs may be ordered through IBM's OS/2 Warp BBS.

The latest, current OS/2 Warp CSD level will be listed in this List and in the
PS Assistant files.  At present there is no Service Pak for OS/2 Warp.  The
latest Service Pak for OS/2 Version 2.1 and OS/2 for Windows is Level 06300.

IBM maintains an unofficial presence on many other networks, including the
Internet.  (You can use OS/2 Warp's Internet Connection to access the full
range of Internet services.)  For general information on the Internet consult
one of the many books describing the network.  One example:  The Whole
Internet by Ed Krol, O'Reilly & Associates (phone 707-829-0515), ISBN
1-56592-025-2.  Once you start using the Internet you should peruse the
information files posted to the news.answers newsgroup to familiarize yourself
with Internet resources.

The OS/2 Warp Roundtable (Page 1400, Keyword OS2) has opened on GEnie.  To
subscribe to GEnie, set your communications software to half duplex and either
1200 or 2400 bps then have your modem dial 800-638-8369 (800-387-8330 in
Canada).  Upon connection, type HHH and press RETURN.  At the U#= prompt type
SIGNUP and press RETURN, then follow the directions given.

Delphi not only provides full access to the Internet (GO INT), but there is
also a dedicated OS/2 Warp forum (GO CUS 41) available on the service.  The
base rate is only $20 for 20 hours of access per month.  To sign up for
Delphi's five hour free trial and save the $19 signup fee (if you end up
joining permanently), (1) call 800-695-4002 with your modem; (2) at the
CONNECT message press ENTER a couple times; (3) at the USERNAME prompt type
JOINDELPHI and press ENTER; (4) at the PASSWORD prompt type CUSTOM41 and press
ENTER; (5) follow the instructions to sign up for the service.  (Your five
free hours expire at the end of the calendar month you sign up for Delphi, so
you probably will not want to sign up at the end of the month unless you use
the free time right away.)

(4.9) Books and Magazines

 What OS/2 Warp books and magazines are available?

OS/2 Warp has its own magazines:  OS/2 Developer Magazine (phone 800-WANT-OS2
or 708-647-5960, FAX 708-647-0537), Inside OS/2 (phone 502-491-1900), OS/2
Professional (phone 301-770-7302), and OS/2 Magazine (Miller-Freeman; phone
800-765-1291 or 415-905-2200, or FAX 415-905-2499).

Many OS/2 Warp books can be ordered by calling the IBM OS/2 Warp Hotline at
800-342-6672.  Or you may obtain OS/2 Warp books through most computer book
sellers.  The most popular, general user guides to OS/2 Warp include OS/2 Warp
Unleashed (by Moskowitz and Kerr), Inside OS/2 Warp (published by Que), and
Your OS/2 Warp Consultant (by Herb Tyson).  Other books (both new and updates
to existing OS/2 titles) are also available.

Several publishers specialize in OS/2 Warp.  For example, Van
Nostrand-Reinhold publishes perhaps the largest selection of books
(particularly on programming topics) relating to OS/2 Warp.  If you cannot
find a good selection of OS/2 Warp books at your favorite computer book
vendor, ask your dealer to order the titles that interest you or contact one
of the (3.15) Dealers Specializing in OS/2 Warp.

IBM publishes technical guides on various OS/2 Warp topics called "redbooks."
To order these and other IBM publications phone your local IBM office and ask
for the Librarian or phone 800-765-4IBM.  Many IBM publications are available
in both printed and CD-ROM formats.  Some IBM publications are also available
by calling IBM Technical Books at 800-IBM-PCTB.

(4.10) Problem Report Form

 How do I report an OS/2 Warp problem to IBM?

If you would like to send an OS/2 Warp bug report to IBM, you may phone IBM at
800-992-4777 (in the U.S.)  or you may fill in the OS/2 Warp Problem Report
Form and mail it to IBM via CompuServe or the Internet.

The Problem Report Form helps IBM solve your problem more quickly, especially
if you include all the relevant details.  IBM then has to ask fewer questions
in order to determine the problem.

To use the Problem Report Form, follow these steps:

1. If you are reading the INF version of this List, press CTRL-F.  This panel
will then be saved to a file named TEXT.TMP.

2. Using a text editor (like the OS/2 Warp System Editor), open either
TEXT.TMP or the plain text version of this List.

3. Delete all the extra lines in the file so that only the OS/2 Warp Problem
Report Form remains.

4. Fill in all the requested information using your text editor.

5. Save the Form to disk (as file name OS2PROB.TXT for example).

6. Upload the file to CompuServe Mail or the Internet, and send the Form to
IBM.  (The exact procedure will depend on the service and the software you

You may use the Problem Report Form as many times as you need to, but please
include only one problem per copy.

  ------  Submit an OS/2 Warp Problem Report  ------

  This support is eligible for U.S. customers only.

  Customers should use this form to report a suspected OS/2 Warp defect to
  IBM support.  IBM employees should refer to the OS2DFECT FORUM in IBMPC
  for instructions on how to report an OS/2 Warp defect.

  If you have how-to or other questions about OS/2 Warp, please refer to these

  - The OS/2 Warp on-line documentation and README file.
  - If you have a CompuServe ID, you may submit an item to the
    appropriate section within the forums under IBMOS2 (GO IBMOS2).
  - Many bulletin board systems contain user forums where OS/2 Warp users
    share information and ideas on OS/2 Warp.

  Please provide as much information as possible on your problem.  Feel free to
  add additional space, or remove sections of the form that are not relevant to
  your problem.

(5.1) Making OS/2 Warp Resemble Unix

 I'm a Unix wizard.  How do I make OS/2 Warp resemble Unix?

A great number of GNU and Unix utilities have been ported to OS/2 Warp native
mode and are available from (3.2) Shareware and Freeware Sources.  A uucp
package, UUPC/Extended, is available via anonymous ftp from,
directory /pub/uupc; mail with questions.

In addition, the Hamilton C Shell is available from Hamilton Labs (phone
508-358-5715 or mail  The Thompson Toolkit, a
Bourne-like shell, and awk are published by Thompson Automation (phone
206-224-1639).  MKS (phone 519-884-2251 or mail publishes a
number of standard Unix utilities for OS/2 Warp.  An OS/2 Warp version of lint
is available from Gimpel Software (phone 215-584-4261).  OS/2 Warp comes with
full featured Internet access software called the Internet Connection.  For
OS/2 Warp-specific X Windows server support, IBM provides an optional package
available with its TCP/IP Version 2 for OS/2.  (Hummingbird and AESoft also
sell X-Window server kits for OS/2 Warp.)

DOS and Windows based utilities and aids still work fine under OS/2 Warp.

(5.2) Making OS/2 Warp Resemble Windows

 I prefer Windows.  How do I make OS/2 Warp resemble Windows?

Spend some time with the Workplace Shell first.  Browse the online Tutorial,
Master Help Index, and Information folder.  Once you are used to the Workplace
Shell, you may find that you will never want to go back.

If you still prefer Windows-like behavior, follow the instructions in your
OS/2 Warp printed manual (or consult the online Command Reference) to use the
MAKEINI utility with the WIN_30.RC configuration file.

Note that you can run the Win-OS/2 Program Manager "seamlessly" on your OS/2
Warp desktop, and you can use it to launch DOS, Windows, and even OS/2 Warp
applications.  Using the Program Manager in this way can make even hard core
Windows users more comfortable.

(5.3) Recovering from Crashed Sessions

 Sometimes OS/2 Warp will freeze when I run an application.  What do I do?

Before rebooting with CTRL-ALT-DEL, try CTRL-ESC.  Do not hit additional keys,
do not move the mouse.  Wait up to a minute.  Either the Window List or an
error message should pop up.  You may close the offending application at that
point; allow some time for it to close.  (Try ALT-ESC if you have disabled
CTRL-ESC in that application's DOS Settings.  If you do not get any response,
press CTRL-ESC or ALT-ESC repeatedly until the dialog appears.)  Note that the
Workplace Shell can recycle, independent of running applications, if it

If the system is badly disabled, sometimes pressing CTRL-ALT-NUMLOCK twice
will result in a prompt to create a dump diskette.  You may do so (the online
Command Reference describes dump diskettes), or at that point you may reboot

To prevent applications from automatically restarting see (5.10) Clever
Tricks.  To restore the desktop to "factory defaults," and for other system
recovery options, use ALT-F1 when OS/2 Warp starts (when you see the white
rectangle as OS/2 Warp boots).

(5.4) Starting Background Processes

 How do I start a background process from the OS/2 Warp command line?

Look up the START and DETACH commands in the online Command Reference.

If you wish to start a DOS session with nondefault settings, use a utility
such as STARTD.  If you wish to start an OS/2 Warp session from a DOS session,
try OS2EXEC.  Both (and several others) are available from (3.2) Shareware and
Freeware Sources.

(5.5) Adobe Type Manager

 How do I add new Adobe Type Manager typefaces?

OS/2 Warp comes with built-in Adobe Type Manager (ATM) for OS/2 Warp and
Win-OS/2.  A basic set of typefaces (Courier, Helvetica, and Times New Roman)
comes with OS/2 Warp and is installed (if selected) for use under both OS/2
Warp's and Win-OS/2's ATM.

Each typeface you install under OS/2 Warp and/or Win-OS/2 should come with at
least two separate files with PFB and AFM extensions.  To install a typeface
for use under Win-OS/2, use the ATM Control Panel.  The Win-OS/2 ATM Control
Panel will then build a PFM file from the AFM file if a PFM file is not
already included.  To install a typeface for use with OS/2 Warp-specific
applications, select OS/2 System -> System Setup -> Font Palette -> Edit Font
-> Add.

PFM files may converted to AFM files using the PFM2AFM utility, available from
(3.2) Shareware and Freeware Sources.  (However, these converted AFM files
sometimes produce unusual results.)  AFM files for Adobe commercial typefaces
are available via Internet anonymous ftp from; the PFB
files are available for purchase from Adobe.  Many public domain typefaces for
OS/2 Warp's ATM are available from (3.2) Shareware and Freeware Sources.
AllType (Atech Software, phone 800-786-FONT), FontMonger (Ares Software, phone
415-578-9090), and Fontographer convert between TrueType and Adobe Type 1

Typeface files may be shared by OS/2 Warp ATM and Win-OS/2 ATM.  To do so,
install the typefaces using both the Font Palette and Win-OS/2 ATM Control
Panel, specifying the same target path each time (most conveniently \PSFONTS).

Note that in some releases of OS/2 IOPL=YES should appear in CONFIG.SYS for
proper operation of ATM.  This setting is the default.

(5.6) Performance Tuning

 How do I tweak OS/2 Warp for maximum performance?

For advice on tuning OS/2 Warp (including information on running games) please
consult the documents located in the Information folder.  Also, several tools
have been developed to help tune OS/2 Warp for performance, notably:

Here are some basic steps you can take to improve the performance of your OS/2
Warp PC:

o Use FastLoad so that Windows applications start faster.  Start the Win-OS/2
Setup program, located in your System Setup folder.  There is a checkbox
marked "FastLoad."  Check this box to enable the FastLoad feature.  When you
start OS/2 Warp, a DOS session with Win-OS/2 will be started automatically and
preloaded so that Windows applications will start faster.  However, enabling
FastLoad will increase the amount of time required to start OS/2 Warp.

FastLoad will not provide any benefit if (a) you have enabled the "Separate
session" feature for your Windows application(s); (b) your FastLoad session is
set for a different mode than your Windows application(s).  In other words, if
your FastLoad session is set for Enhanced mode, the Windows applications you
start from the OS/2 Warp desktop must also be set to Enhanced mode.  You can
adjust the FastLoad mode setting by using the Win-OS/2 settings button in the
Win-OS/2 Setup notebook.  The mode setting for a Windows application is
controlled from the settings notebook for that application.  If the mode
settings are not identical, FastLoad can actually hamper performance.

o Adjust the disk cache size.  Generally, OS/2 Warp can make better use of
your PC's memory for applications, so you will usually want to keep the size
of your disk cache modest.  There are at least three types of disk caches
available:  FAT, HPFS, and CD-ROM.  All are controlled by the CONFIG.SYS file.
Normally OS/2 Warp will set the disk cache sizes correctly for your PC's
amount of memory.  However, you may wish to make changes, especially if you
have added or removed memory from your PC.

As a rule of thumb, the total size of your disk caches (combined) should be
about 10% of your PC's available memory.  For example, if you have a system
with 12 MB of memory, then you can spare a little over a megabyte (1024K) for
disk cache.  The cache sizes for the three most popular OS/2 Warp file systems
are controlled using the following lines in CONFIG.SYS:

    IFS=[...]HPFS.IFS /CACHE:yyyy [...]
    IFS=[...]CDFS.IFS /C:zz [...]

(for FAT, HPFS, and CD-ROM, respectively).  The "[...]" notation above
indicates that additional, optional parameters are available for these lines.
Replace "xxxx" or "yyyy" with the size of the cache you would like (in
Kilobytes).  For example, to set a cache size of 1 MB for the FAT file system:


Replace "zz" with the size of the CD-ROM cache you wish to set, in 64K
segments.  For example, to set a cache size of 128K for the CD-ROM file
system, use:

    IFS=[...]CDFS.IFS /C:2

For more information on setting disk cache sizes, please refer to the online
Command Reference.

o Relocate the OS/2 Warp swap file.  For maximum performance, the swap file
(controlled by the SWAPPATH line in CONFIG.SYS) should be located on the most
used drive on the least used hard disk on your PC.  Also, preallocating a
larger swap file (8, 12, or even 16 MB) can increase performance.  See your
online Command Reference for details on SWAPPATH.

o Speed printing by dedicating IRQ 7. With OS/2 Warp, the default printing
method is to poll the printer port (much like DOS).  This method is compatible
with a wide variety of PCs and printers, but sometimes printing speed suffers.
For faster results, enable interrupt-driven printing.  See (2.3) Printer
Support for details.

  (5.7) Measuring Performance and Memory Usage

(5.7) Measuring Performance and Memory Usage

 How do I measure OS/2 Warp performance and memory usage?

OS/2 Warp does not treat system resources like DOS.  Memory is treated as a
virtual resource, used intelligently.  For example, OS/2 Warp will retain
unused, "dormant" code in memory if that memory is not otherwise required, on
the assumption that that code may be used again.  Also, all but a small
portion of OS/2 Warp (and most applications, no matter how many are running)
may be paged to disk should a large amount of physical memory be required.
Utilities which display "free" memory, then, are only useful for rough,
relative measurements.  (Such utilities also often fail for another reason:
many only report the largest contiguous block of free physical RAM.  And a few
will never report more than 16 MB of RAM because they were designed for OS/2

Similarly, utilities which purport to measure system load (e.g.  Pulse) should
not be relied upon for definitive performance measurement.  Subjective
assessments are often much more reliable.  Pulse (and similar utilities) rely
on a measurement of processor time allocated to a thread running at OS/2
Warp's lowest priority.  This method is sometimes subject to erroneous

That said, more rigorous system performance optimization and monitoring tools
include IBM's System Performance Monitor/2, BenchTech (Synetik, phone
303-241-1718), OR/SysMon (International OS/2 User Group, phone +44-285-641175
or FAX +44-285-640181), CPU Monitor (BonAmi), and Performance 3.0 (Clear &
Simple, phone 203-658-1204).

Note that OS/2 Warp's swap file is designed to behave with hysteresis.  It
will not shrink in size as easily as it grows, under the assumption that swap
space needed once may be needed again.  It should shrink given enough time and
continued, less intense system loads.

(5.8) Displaying Background Bitmaps

 My background bitmap does not display correctly.  What's wrong?

Color bitmap images used for the Workplace Shell screen or folder backgrounds
may not display correctly (may have distorted or missing colors) due to
incorrect matching with OS/2 Warp's default palette.  Unlike Windows, by
default OS/2 Warp does not adjust the palette to accommodate background
bitmaps (to keep the rest of the desktop from experiencing color distortions).
Applications, though, can always control the palette selection when they are
in the foreground.

If you would like OS/2 Warp's Workplace Shell to change palettes, when
possible, to make your background bitmap(s) look better, check the "Workplace
shell palette aware" checkbox, located on the first page of the System object
(which is located in your OS/2 Warp System Setup folder).  Alternatively, you
may use the numerous background images which have been specifically prepared
for the Workplace Shell [available from (3.2) Shareware and Freeware Sources]
or you may use an image editing/conversion utility which can create a proper,
system palette-matched bitmap file.  For example, JoeView [available from
(3.2) Shareware and Freeware Sources] may be used to import noninterlaced GIF,
Windows BMP, and PCX files and save them as palette-matched OS/2 Warp BMP

Note that background bitmap images impose some additional overhead, taking up
RAM and disk resources.  You should probably use them sparingly.  Also, if you
have set a Win-OS/2 background bitmap you may experience desktop color
distortions when running Windows programs "seamlessly."  Disable the Win-OS/2
background bitmap to remedy the problem.

(5.9) Specific DOS Sessions

 How do I boot a real version of DOS from within OS/2 Warp?

Booting a real version of DOS under OS/2 Warp provides certain features that
the OS/2 Warp emulated DOS sessions cannot.  For example, a specific DOS
session can provide access to devices (like CD-ROM drives) and networks for
which there are only DOS device drivers.  A specific DOS session can also help
get DOS applications which generate spurious "divide by zero" errors running

You may be able to run only one such session per hardware device (if that
device is not under OS/2 Warp's direct control).  So, for example, if you have
your DOS networking software loaded in one specific DOS session, you may not
start another, similar session which also accesses the same network card.

Specific DOS sessions are discussed in the online Command Reference (under
VMDISK), the Master Help Index, and the printed OS/2 Warp manual.  You should
consult those resources first.  However, if you are still unsure how to
configure your system to run specific DOS sessions, follow these steps:

1. Create a bootable DOS diskette.  Insert your DOS system diskette into Drive
A and reboot.  When you arrive at the "A>" prompt, type FORMAT A:  /S and
press ENTER.  (Note that you may wish to format the diskette for the smallest
capacity possible, to save hard disk space later on.  For example, a 5.25 inch
double density -- not high density -- diskette may be formatted to just 160K
by adding the /1 /N:8 parameters to the FORMAT command.)  When prompted,
insert a blank diskette into Drive A and press ENTER.  When the FORMAT
operation is complete, remove the diskette and restart OS/2 Warp.

2. Copy FSFILTER.SYS to the diskette.  Double click on OS/2 System -> Command
Prompts -> OS/2 Window.  Insert the diskette you just formatted into Drive A.
Copy the following file to your startable diskette:  \OS2\MDOS\FSFILTER.SYS.

3. Set up CONFIG.SYS.  Using a text editor (like the OS/2 System Editor)
create the file A:\CONFIG.SYS with the following lines at the top:


Change the "C:"  drive letter if OS/2 Warp is installed on another drive.  Add
any other lines as required for your application (like CD-ROM or networking),
but do not include any XMS, EMS, mouse, or memory management device drivers.
Make sure that everything is referenced with a drive letter and path, as

4. Set up AUTOEXEC.BAT.  Likewise, create a file named A:\AUTOEXEC.BAT and
make sure that the first line reads:


changing "C:"  if necessary.  Add any additional lines (like PATH, SET PROMPT,
and so on) as required by your application.  Make sure that \OS2\MDOS is
referenced in the PATH.

5. Test your DOS diskette.  Once you have configured the CONFIG.SYS and
AUTOEXEC.BAT files as you wish, double click on OS/2 System -> Command Prompts
-> DOS from Drive A:.  A DOS session should start.  Test for the functionality
you need (like access to your CD-ROM reader or network).  If the session is
not working properly, press CTRL-ESC and shut down the session, edit
CONFIG.SYS and/or AUTOEXEC.BAT as required, and repeat the test.

6. Create the diskette image.  When you are satisfied that your specific DOS
session diskette functions properly, go back to the OS/2 Window and type
VMDISK A:  C:\DOS.IMG to create a diskette image file.  (If you want the file
to be located on another drive or in another directory, change "C:\"

7. Create a program object for your specific DOS session.  Drag a program
object from your Templates folder to any target folder.  When the notebook
opens, enter a single asterisk (*) in the Program Name field, then click on
the right arrow in the lower right.  Select either DOS Window or DOS Full
Screen for the session type, as desired.  Click on the DOS Settings button,
click OK, and scroll down until you find the DOS_STARTUP_DRIVE property.
Enter C:\DOS.IMG in the field at the upper right.  (If your image file is not
located on Drive C in the root directory, make the necessary changes.)  Change
any other DOS Settings if necessary.  Click on the Save button, then click on
the General tab.  Give your program object a name.  Then close up the

You should now be able to double click on your new program object to start
your specific DOS session.  If you require access to your diskette drive
(Drive A), use the FSACCESS command.  See the online Command Reference for

When formatting your bootable DOS diskette, you may wish to use additional
command line parameters to create a diskette with a reduced capacity.  The
"smaller" the diskette, the less room the diskette image file created by
VMDISK will take on your hard disk.  See your DOS manual for details, or use
the example given above.

(5.10) Clever Tricks

 Are there any clever tricks that apply to OS/2 Warp?

o To force DIR to display your directories in alphabetical order, with the
subdirectories listed first, add the line


to CONFIG.SYS; and, if you wish the same for your DOS command line sessions,
add the same line to AUTOEXEC.BAT.  You may also wish to run DOSKEY to enable
the command history feature.  (Shutdown and reboot for changes to CONFIG.SYS
to take effect.)

o Hold down SHIFT while resizing text windows to make size changes permanent.

o If you want to configure your printer port(s) for shared access (so that DOS
programs like LapLink, for example, can use them directly), go to your printer
object, click on it with mouse button two, select Open -> Settings, select the
Output tab, then double click on the port you wish to share.  Check the
appropriate box.

o While running a DOS graphics program in a window, use the graphics cut and
paste feature to clip a picture and paste it into the Icon Editor.  You can
then quickly and easily create custom icons for your applications.

o To disable the automatic application restart feature, add the line


to your CONFIG.SYS.  To manually disable automatic application restart when
booting OS/2, hold down the left CTRL, left SHIFT, and F1 keys simultaneously
from the time the mouse pointer appears until icons are displayed on the

o If you wish to dispense with the Workplace Shell (and its overhead),
particularly on low memory systems, change the line SET RUNWORKPLACE...  in
CONFIG.SYS to read SET RUNWORKPLACE=C:\OS2\CMD.EXE (replacing C, if necessary,
with a different drive letter).  In fact any program with job control (e.g.
Enhanced Editor, HyperAccess/5) can be used as the shell.  [Character mode
alternatives to the Workplace Shell are now available from (3.2) Shareware and
Freeware Sources.]

o To implement a small scroll back buffer for your OS/2 Warp command line
windows, use the command MODE CO80,102.  This procedure may be automated by
adding /K MODE CO80,102 in the Optional Parameters section of the OS/2 Window
program object settings.

o If you do not want any command line parameters passed to a program object
that you start (for example, if you customize the desktop menu so that it has
an additional option which starts a command line prompt) place a lone % in the
Optional Parameters section of the program object settings.  If you do wish to
pass parameters, but you want the extraneous information that the Workplace
Shell passes to the object to be ignored, try putting && REM % in the Optional
Parameters section after the parameters you wish passed.

o If you want to move an icon a small distance, "grab" it from the edge
nearest the direction you want to move the icon.

o A clever way to manipulate files that are locked when the Workplace Shell is
running (e.g.  display drivers) is to add the line CALL=CMD.EXE at the end of
CONFIG.SYS.  Then Shutdown and reboot.  The system will restart with an OS/2
Warp command line prompt.  Type EXIT to proceed into the Workplace Shell.
Using CALL is also a convenient way to configure OS/2 Warp's serial ports
using the MODE command.  For example:


configures COM2 for high speed RTS handshaking and buffered I/O.  [Moreover,
the MODE command can be used to determine whether your system has a buffered
UART (National Semiconductor 16550A or equivalent), nearly essential for high
speed communications.  Use the command:


(where x is the communications port number) from an OS/2 Warp command line.
If you see anything but "BUFFER = N/A" then you have a buffered UART for that

You can use either CDDBOC or SHIFTRUN instead of CALL; both utilities are
available from (3.2) Shareware and Freeware Sources.

Another way, which works well with display drivers, is to copy the new DLL(s)
to its(their) own directory (say, C:\NEW), then place that directory name
first in LIBPATH in CONFIG.SYS.  Shutdown and reboot.  OS/2 Warp will use
that(those) DLL(s) before it attempts to use the one(s) located in \OS2\DLL.
To switch back to the old driver, edit CONFIG.SYS and remove C:\NEW from
LIBPATH, then Shutdown and reboot.

o To shutdown without a mouse, press CTRL-ESC, select the Desktop, then press
the spacebar (to deselect any icons, if necessary), SHIFT-F10, and select

o Selective Install/Uninstall should be used with caution when changing mouse,
multimedia, or display drivers.  Verify that proper changes have been made to

o If your settings notebooks do not display but are listed in the Window List,
click on the name of the settings notebook in the Window List (brought up with
CTRL-ESC) with mouse button two and select Cascade.

o If your \OS2\*.INI files have grown large, use the CopyINI or WPSBackup
utilities to shrink them.  Both are available from (3.2) Shareware and
Freeware Sources.

o To restart the Workplace Shell (without saving desktop settings, perhaps
after an accidental Sort), use a utility such as psPM [available from (3.2)
Shareware and Freeware Sources] to terminate PMSHELL.

o To get rid of a WPS object that cannot be deleted, try one of the following:

- Insert a blank diskette in Drive A, click on the stubborn object with mouse
button two, select Move, select the Path page, enter A:\, press ENTER, then
format the diskette;

- Use the WPSTools or Black Hole, available from (3.2) Shareware and Freeware
Sources.  (The WPSTools can also recreate desktop objects that have been

o To load a device driver into high memory in a particular DOS session change
the DOS_DEVICE setting for the session and add SIZE=0 before the path and
filename for the device driver.  For example, the following DOS_DEVICE entry:


loads the ANSI.SYS device driver into high memory in that particular session.

o To reboot the machine from the command line, use:


Change the last letter (C) if you want to boot from another drive.  Disk
buffers will be flushed, but Workplace Shell settings will not be saved.

o The settings notebooks now support drag and drop operations for assigning
icons and for changing menus.

To change the icon for an object, first open the settings notebook (click on
the object with the secondary mouse button, then select Open -> Settings).
Click on the General tab.  Then drag any other object to the icon located on
the General page of the settings notebook.  The object's icon will change to
match.  If you want to restore it to its former state, click on the Undo

To assign actions to menus, open the settings notebook, then click on the Menu
tab.  Click on any of the items in the Available menus section (or Create
another).  To add an Action, drag the desired program object to the Actions on
menu section.

o To quickly maximize a window, double click on its title bar.  To restore the
window to its former size, double click on the title bar again.

o If you have UNDELETE enabled, but you want to delete an occasional file
without the overhead incurred by having UNDELETE capability, use the /F
parameter with the DEL command.  Using this parameter (in either a DOS or OS/2
Window) will bypass the routine which moves the file(s) to the directory
specified by the DELDIR environment variable.  The file(s) is(are) deleted
faster, but you will not be able to undelete it(them).  The /N parameter will
prevent prompting ("Are you sure?").

o OS/2 Warp includes the ability to set a power on password.  However, if you
have forgotten your password, and you cannot unlock your desktop when you turn
your machine on, try the following.  Start OS/2 Warp from a diskette boot [see
(4.4) Starting OS/2 Warp from Diskette] to get a command line prompt.  At the
prompt, enter the following commands:


(assuming OS/2 Warp is installed on Drive C; change if necessary)


o If you are using a 1024x768 display driver (such as 8514/A), but you do not
want the icons scaled up in size from 32x32 to 40x40, patch the display driver
file (e.g.  \OS2\DLL\8514_32.DLL) using DEBUG or a similar utility.  Search
for the hexadecimal byte sequence 28 00 28 00 20 00 20 00 and replace the two
28 values with 20.  Reboot for the change to take effect, and be sure to keep
a backup copy of the original file.

o To hide your entire desktop, single click on any icon on the desktop, press
CTRL-ESC, then press CTRL-SHIFT-ESC.  To return the desktop to normal, press
CTRL-ESC then double click on Desktop.

o If you would like to have a Presentation Manager application start up
minimized, first set up a program object for it by dragging a Program template
from the Templates folder.  Then, on the first page of the notebook, enter the
full path and filename of the PM program, but deliberately misspell it.  Click
on the arrow in the lower right to turn the page, then check the Start
minimized checkbox.  Click on the left arrow to turn the page back, then
correct the misspelling.  Fill in any other information, as desired, then
close up the notebook.  The program object is now ready to start your PM
application minimized.

o To get approximately 730K free in your DOS sessions, change
VIDEO_MODE_RESTRICTION in the session's settings to CGA (unless your
application requires more than CGA graphics capabilities).

o In a full screen, character mode OS/2 Warp session it is normally impossible
to copy text from the screen to the Clipboard.  To get around the problem, try
setting your printer object to hold all print jobs, press the PrintScreen key
while the full screen OS/2 Warp session is active, return to the printer
object and double click on the print job icon for the PrintScreen, then cut
and paste from the editor.

(5.11) REXX

 How do I use REXX?  What does it do?

REXX is built into every copy of OS/2 Warp (where it is also known as
Procedures Language/2).  It is a general purpose, interpreted programming
language which was first released on IBM mainframes over a decade ago.  REXX
is extremely easy to learn and use.  It is particularly strong at string
manipulation, and it has features which are difficult to implement in compiled
languages (like the ability to read its own source code or execute a string as
a command).

OS/2 Warp applications can use REXX as a common scripting language, which
means that users need not learn separate macro or script languages for each
application.  For example, the OS/2 Warp versions of Lotus 1-2-3 and Borland
ObjectVision will interface with REXX.  OS/2 Warp's multimedia extensions
(MMPM/2) contain a REXX interface, so REXX programs can play, record, and
manipulate sound and video files.  And REXX can be used to create complex
batch files (with interactive prompting), since it is integrated so tightly
into OS/2 Warp's command processor.  Moreover, a trio of REXX visual builders
(programming tools which help create even complex REXX applications quickly
and easily using simple, drag and drop manipulation of on screen objects),
HockWare's VisPro/REXX, Watcom's VX REXX, and Gpf REXX, are now available.

For more information on OS/2 Warp's REXX interpreter, see the REXX Information
online documentation located in the Information folder.  For more information
on REXX generally, consult the REXX Frequently Asked Questions List [available
from (3.2) Shareware and Freeware Sources].  Or consult one of the many books
available on REXX under OS/2 Warp, including OS/2 REXX:  From Bark to Byte
(IBM Publication No.  GG24-4199) and REXX Under OS/2 by G.F.  Gargiulo (Wiley,
ISBN 0471-519-014).

Here are some REXX hints and tips:

o If you wish to place program output in the REXX queue (for processing by a
REXX program), try


as an example.  (In other words, pipe the program output to RXQUEUE.)  To use
this program output in your REXX program, try

    /* Sample */
    WHILE QUEUED() > 0
    SAY X

o To execute REXX commands interactively from the command line, use the
REXXTRY command.  For example:

(5.12) ANSI Escape Sequences

 What ANSI escape sequences can be used?

ANSI escape sequences provide cursor and screen control in OS/2 Warp character
mode sessions.  By default ANSI support is turned ON (although it may be
turned off with the command ANSI OFF).  ANSI support is also available in DOS
sessions if the device driver ANSI.SYS is loaded.  See the online Command
Reference for details.

The following ANSI escape sequences are available:

  ESC       Refers to ASCII code 27 (i.e. the Escape key)
  #         Replace with the appropriate number
  ....      Replace with additional attributes, if desired

  Escape Code Sequence          Function
  Cursor Controls
  ESC[#;#H or ESC[#;#f          Moves cursor to line #, column #
  ESC[#A                        Moves cursor up # lines
  ESC[#B                        Moves cursor down # lines
  ESC[#C                        Moves cursor forward # spaces
  ESC[#D                        Moves cursor back # spaces
  ESC[#;#R                      Reports current cursor line and column
  ESC[s                         Saves cursor position for recall later
  ESC[u                         Return to saved cursor position

                                DIR command.
                                The 0;68 portion is the extended ASCII code for
                                the F10 key and 13 is the ASCII code for a
                                carriage return.  Other function key codes:
                                F1=59, F2=60, F3=61, ... F10=68.

You can use ANSI escape sequences in the PROMPT environment variable to create
complex command line prompts.  See the online Command Reference (under PROMPT)
for details.

For example, if you have a color monitor, try editing your CONFIG.SYS file so

  SET PROMPT=$e[32;40m$e[1m[$P]$e[0m

to obtain a more colorful OS/2 Warp command line prompt.  (Case is significant
in the example given.)  You can do the same for your DOS sessions if you edit
PROMPT in AUTOEXEC.BAT, assuming you have ANSI.SYS loaded.  Note that the $i
portion of your PROMPT will enable the help line at the top of the window or
screen.  It is not included in the example above.

 (6.3)  What is IBM?

 (6.4)  What is the MIDI file IBMRALLY that I get with OS/2 Warp's multimedia?

(6.1) Promoting OS/2 Warp

 What can I do to promote OS/2 Warp?

OS/2 Warp is selling well, but there are steps you can take to assure that
hardware devices and software will be available for OS/2 Warp in the future.
Customer requests do matter.

o Politely, firmly, and repeatedly request driver support from printer, video
adapter, and other hardware manufacturers.

o When you receive a mailing for DOS/Windows software with a postpaid
envelope, return the order form marked "Please send information on your native
OS/2 Warp version."

o Start a user group at your location.  Contact Gene Barlow or Richard Woolsey
at IBM (phone 214-402-6456) or mail for assistance.
Think about how you can publicize your user group.  For instance, most local
newspapers and television stations will print/broadcast meeting announcements
for free.  Your local cable television company will be happy to broadcast a
videotape of your meeting on the public access channel.

o Correspond with members of the computer trade press.  Ask for reviews of
OS/2 Warp software, hardware compatibility testing with OS/2 Warp, OS/2 Warp
benchmarking, etc.  Respond politely but forcefully to press you think unfair;
praise good reporting.

o When you purchase a new system, ask the vendor to install OS/2 Warp, and to
offer credit for dropping DOS and Windows.  If the vendor refuses, you may
wish to take your business elsewhere.  Compaq, Everex, AST, Northgate,
Toshiba, Vobis, Escom, Osbourne, Patriot, CompuAdd, ALR, Unisys, Dell,
Tangent, IBM, Ariel Design, and others all offer systems with OS/2 Warp

o Make sure your company (or yourself) specifies OS/2 Warp compatibility when
purchasing new products.

o Demonstrate OS/2 Warp to friends, relatives, and associates.

o Ask your computer store to stock OS/2 Warp software titles, have OS/2 Warp
demonstration machines, etc.

o Pass along useful OS/2 Warp shareware and freeware to your local BBS.  Be
sure to register OS/2 Warp shareware.

o Write an outstanding piece of shareware or freeware [see (4.5) Technical
Support for details on joining DAP].  IBM has been known to recognize such
work with rewards.  Also, ask authors of DOS/Windows shareware and freeware if
they would port to OS/2 Warp, or volunteer.

o Recommend products that work well under OS/2 Warp; dissuade people from
purchasing products that do not.

o Wear OS/2 Warp pins, shirts, buttons, and other souvenirs.  Contact the
Lees/Keystone OS/2 Warp Merchandise Center (phone 914-273-6755 or FAX
914-273-9187) or the IBM OS/2 Warp Hotline (phone 800-3-IBM-OS2) to order such

o Join Team OS/2, an international organization of volunteers who are OS/2
Warp enthusiasts and are actively sharing their knowledge and enthusiasm with
others.  These activities include supporting OS/2 Warp user groups, running
OS/2 Warp BBSes and online conferences, demonstrating OS/2 Warp at retail
stores and other public places, encouraging and helping others to install OS/2
Warp, answering OS/2 Warp questions, and much more.  Membership is not limited
to IBM employees.  For information on Team OS/2 events you should monitor the
TEAMOS2 echomail conference on your local FidoNet BBS.  If your local BBS does
not carry TEAMOS2, ask your system operator to get it.  See (4.11) OS/2 Warp
BBSes for the names and numbers of several BBSes which carry TEAMOS2.  To join
Team OS/2, send your name, address(es), and telephone number to Vicci Conway
(netmail or FAX 407-982-1229).  Include information
on your activities to date and a one line description of yourself for the
public Team OS/2 list.

(6.2) Creating INF Files

 How can I create INF files?

Creating INF files (like the OS/2 Warp Frequently Asked Questions List you are
reading now) is remarkably straightforward.  All you need is the Information
Presentation Facility Compiler (IPFC), part of the IBM Developer's Toolkit for
OS/2 Warp Version 3 (available separately or as part of many development
environments such as Borland C++ for OS/2, IBM C Set ++/2 and First Step, and
CA-Realizer), and a text editor (like the Enhanced Editor included with OS/2
Warp).  You can also purchase and/or download tools specifically designed to
create OS/2 Warp help/INF files, including IBM Hyperwise, IPFE, and many more.

Online IPFC documentation is included with the Toolkit, but you may also wish
to order the printed Information Presentation Facility Guide and Reference,
IBM Publication No.  S10G-6262.  See (4.9) Books and Magazines for ordering
instructions.  Note that the Toolkit is part of the low cost OS/2 Developer's
Connection CD-ROM.  See (4.5) Technical Support for details.

If you wish to include illustrations in your INF file you can use any graphics
software which can generate OS/2 Warp bitmaps and/or metafiles.  (For example,
you may create your illustration in IBM Works, paste the illustration into
Picture Viewer, then save the illustration as a metafile.  Both IBM Works and
Picture Viewer are included with OS/2 Warp.)  A screen capture utility [like
PM Camera or Galleria, available from (3.2) Shareware and Freeware Sources]
can also prove useful.

The May, 1994, issue of OS/2 Magazine contains an article written by Timothy
F. Sipples on writing OS/2 help files.  You may wish to consult this article
for an introduction to the IPFC tag language.

(6.3) What is IBM?

 What is IBM?

IBM (International Business Machines Corp.)  is the world's largest provider
of computing solutions.  The company's software operations make IBM the
largest software company in the world, with approximately $12 billion in
annual revenue.  IBM Corp.  provides direct employment to approximately
220,000 people worldwide.  Its stock is traded on the New York Stock Exchange
(symbol:  IBM), and it is one of the Dow Jones 30 Industrials.

IBM was founded in the early part of the 20th century when its business
primarily consisted of the manufacture and sale of scales, tabulating
machinery, and other instruments for government and industry.  During World
War II, IBM was invaluable to the war effort.  Its scientists designed and
built the first electronic computer (the Mark I).  Beginning in the 1950s, IBM
manufactured and sold computer systems to large numbers of other companies,
revolutionizing the conduct of business worldwide.  The company achieved
dominance (and remains preeminent) in many areas in the computer and software
industries.  IBM is the world's largest holder of patents relating to
computing (including software) technologies, for example.  The company has
engaged in basic research for decades, resulting in such products as the
diskette drive.  Its scientists have most recently pioneered such areas as
superconductors, perpendicular recording techniques, and manipulation of
individual atoms to record information.

Today IBM manufactures, markets, and services a wide range of computing
products.  Hardware products include the ES/9000 family of mainframe
computers, AS/400 line of midrange computers, RS/6000 workstations, Thinkpad
notebook computers, Aptiva home/small business PCs, and IBM brand PCs for
government and business.  Software products include operating systems (OS/2
Warp, MVS, VM, OS/400, AIX, PC-DOS, and many others), databases,
communications, networking, multimedia, CAD/CAM, programming, and much more.
IBM also competes in areas such as banking systems (automatic teller machines,
check processing equipment, etc.), point-of-sale systems (cash registers,
barcode scanners, etc.), factory floor systems (computer controlled production
equipment, robotics, monitoring), and much more.  IBM also produces computers
and software designed so that persons with disabilities can enjoy life to the
fullest.  Products such as Screen Reader/2, Screen Magnifier/2, and many more
are available through IBM's Special Needs Division.

Through its joint ventures, subsidiaries, and partnerships, IBM is engaged in
a wide variety of other lines of business.  For example, Sears and IBM are
co-founders of Prodigy Services Company.  Sears and IBM also jointly own
Advantis (part of the IBM Global Network), a company providing network
connections (including connections to the Internet) to individuals, companies,
and institutions around the world.  IBM, Apple, and Hewlett-Packard each hold
stakes in Taligent, a software company producing object-oriented technologies
for inclusion in several operating systems, including OS/2 Warp.  Apple and
IBM each own half of Kaleida, the company producing ScriptX, a standard
architecture for producing multimedia presentations.  IBM's EduQuest designs
and markets PCs and software for K-12 education, including "Columbus" and
"Illuminated Books and Manuscripts" (multimedia software titles for OS/2).

A complete history of IBM, as well as a full report on IBM's current and
future endeavors, would occupy volumes.  However, the few paragraphs included
here should give you an idea of the scope of IBM's business activities.

Mr.  Louis Gerstner is the Chairman and Chief Executive Officer of IBM Corp.,
headquartered in Armonk, New York, U.S.A.  Mr.  John Thompson is head of IBM
Software, the worldwide organization responsible for developing and marketing
all of IBM's software products.  Mr.  Leland ("Lee") Reiswig ("The Blue
Ninja") is the President of the Personal Software Products Division at IBM,
the division which develops OS/2 Warp and many of IBM's software products for
PCs.  The bulk of the Personal Software Products Division workforce is based
in Boca Raton, Florida, and Austin, Texas.

 What is the MIDI file IBMRALLY that I get with OS/2 Warp's multimedia?

If you have a sound card which can play back MIDI files, you can use the MIDI
Player (in your Multimedia folder) to listen to any of the sample MIDI files
provided with OS/2 Warp.  IBMRALLY.MID is an instrumental recording of IBM's
theme song, "Ever Onward IBM."

Here are the words so that you can sing along.  Bear in mind that the lyrics
date back decades, when women were not routinely employed in most industries
(especially engineering and computing).

 There's a feel-ing ev'ry where of big-ger things in store,
 Of new hor-i-zons com-ing in-to view.
 Our aim is clear: to make each year ex-ceed the one be-fore,
 Stay-ing in the lead in ev'ry-thing we do.
 The will to win is built right in,
 It will not be de-nied,
 And we will go a-head we know by work-ing side by side.
 Ev-er On-ward, Ev-er On-ward,
 That's the spir-it that has brought us fame.
 We're big but big-ger we will be.
 We can't fail for all can see
 That to serve hu-man-i-ty has been our aim.
 Our pro-ducts now are known in ev'ry zone.
 Our rep-u-ta-tion spark-les like a gem.
 We've fought our way thru and new
 Fields we're sure to con-quer too
 For the Ev-er On-ward I-B-M.
 Ev-er On-ward, Ev-er On-ward,
 We're bound for the top to nev-er fall.
 Right here and now we thank-ful-ly
 Pledge sin-cer-est loy-al-ty
 To the cor-por-a-tion that's the best of all.
 Our lead-ers we re-vere,
 And while we're here,
 Let's show the world just what we think of them!
 So let us sing men, sing men,
 Once or twice then sing a-gain
 For the Ev-er On-ward I-B-M!

(7.0) Glossary

The following terms are often used in conjunction with OS/2 Warp:


A bug fix which has been (or will be) created by IBM to address a very
specific problem.  (Example:  "Please send me APAR 09761.")


Adaptec SCSI Programming Interface:  a standard set of services used by
backup, scanning, and other types of software which require access to a SCSI
adapter.  OS/2 Warp comes with ASPI support for DOS, Windows, and OS/2


Free, full fledged applications included with OS/2 Warp at no extra charge.
The BonusPak includes HyperAccess, Faxworks, Person to Person, the Internet
Connection, Compuserve Information Manager, Video IN, IBM Works, and other
applications.  These applications not only demonstrate how powerful and
easy-to-use OS/2 Warp really is, but they also let you get to work (or play!)
right out-of-the-box.


"Configuration/Installation/Distribution":  a term usually used to refer to
the ability to install an operating system or application remotely, over a
network.  (Example:  "IBM TCP/IP 2.0 for OS/2 is now CID-enabled.") See (4.2)
Installing from Drive B.


"Corrective Service Diskette(s)":  see (4.6) Corrective Service Diskettes.


"Direct Access Storage Device":  disk space (most commonly a hard disk drive).
(Example:  "I do not have enough DASD for this new application.")


"Distributed Computing Environment":  an open software standard, created by
the Open Software Foundation and backed by IBM and other vendors, which allows
for applications to operate across a network and distribute the workload
without a significant investment in programming.  DCE supports common
directory services (for accessing resources on a network), security (for
preventing unauthorized or runaway applications from wreaking havoc on a
network), and other management features.  OS/2 Warp is a key platform for DCE,
and IBM produces the most advanced implementations of DCE available on the


"Direct Memory Access":  circuitry provided on all PCs to allow peripherals
(such as disk controllers) to transfer data to memory directly, without the
assistance of the computer's processor.  Appropriate use of DMA can often help
to improve overall system performance.


"DOS Protected Mode Interface:  a method used by some DOS applications
(including Windows) to access memory beyond 640K on 80286 (or later)
processors.  OS/2 Warp can provide DPMI memory to DOS and Windows
applications.  See EMS and XMS.


"Extended Attribute":  up to 64K of assorted data stored with any file under
OS/2.  Such data may include file type (e.g.  "Plain Text"), icons, comments,
and other information which is best left outside the file itself.  Only OS/2
applications can create and modify extended attributes.


"Expanded Memory Specification":  one of several types of memory (beyond 640K)
that can be used by certain DOS applications.  OS/2 Warp can provide EMS
memory to DOS applications.  See DPMI and XMS.


"Extended Services":  see (3.10) Extended Services.


"File Allocation Table":  the disk format introduced by DOS.  See HPFS.


"General Availability":  available for purchase as a shrinkwrapped product
from IBM and its dealers.


"High Performance File System":  see (1.5) High Performance File System.


"Installable File System":  refers to an OS/2 driver used to manage a file
system type.  Available IFSes include NFS (used with TCP/IP networks), CD-ROM,
HPFS, and HPFS386 (supplied with IBM LAN Server Advanced).


"Initial Program Load":  starting a PC's operating system (i.e.  booting or
rebooting).  (Example:  "Please IPL your system now.") See also RIPL.


"Independent Software Vendor":  a software developer, other than the provider
of the operating system (such as IBM and OS/2), which produces applications
for that operating system (e.g.  Borland is an OS/2 ISV, producing Borland C++
for OS/2).


"Limited Availability":  available only from IBM to certain customers.


Running two or more applications "simultaneously," dividing the computer
processor's attention among them.  (In fact, the two or more applications only
appear to run simultaneously because the processor switches between them
rapidly.)  Cooperative multitasking, such as that found in Microsoft Windows
and Macintosh System 7, requires that each application be written so as to
"surrender" the computer's processor at regular intervals so that it can
devote attention to other running applications.  If one application for some
reason refuses to yield the processor, all other applications stop running.
Preemptive multitasking, as found in OS/2 and Unix, for example, leaves the
operating system in charge of delegating processor time to each running
application.  The amount of attention given depends on the operating system's
scheduler, the logic which assesses (and perhaps adjusts) the priorities of
various tasks and assigns processor attention accordingly.


An operating system's ability to manage what are sometimes called lightweight
processes, namely subtasks which are spawned by applications.  For example, a
word processor may be written so that any printing operation is put in a
separate thread.  This thread is then run alongside the word processor itself,
in the background, so that control returns immediately to the user of the word
processor.  OS/2 1.0 was the first major operating system to support threads.
See multitasking.


The basic unit of interaction in OS/2 Warp.  In some environments, such as
Windows, users work only with files.  In other environments, such as the
Macintosh, users work with documents and applications.  In OS/2 Warp, users
work with objects (of which files and documents are but two types).  OS/2 is
easy to use because objects are generally not restricted in the ways they can
be used based on computer-oriented restrictions (such as the length of names
for objects).  Rather, objects can be treated in very similar ways when using
OS/2, with differences related to more human ideas of how things behave.  For
example, in OS/2 Warp every object (including the desktop itself, which is a
folder-type object) has a pop-up menu, brought up with a click of the second
mouse button.  Printer objects have unique menu options (such as Change Status
and Set Default).  Likewise, document objects have other possible menu
selections (such as Print).  Disk objects have Format.  But the whole point is
that the user, not the computer, dictates how objects can be used and
manipulated, insofar as possible.


A set of technologies (slated for inclusion in OS/2 Warp in 1995) which,
together, will deliver unprecendented flexibility in the way applications and
objects can be combined, manipulated, and transformed by people using
computers.  OpenDoc recognizes that people are creating more and more complex
documents, including documents which contain embedded runnable code (such as
multimedia sound and video clips which activate with a mouse click), and they
need a way to store, manage, link, and revise such documents, without
unnecessary complexity.  OpenDoc is a standard supported by members of the
Component Integration Laboratories, including IBM, Apple, WordPerfect, Lotus,
Novell/Wordperfect, and many other vendors.  SOM is a key technology found in
OpenDoc (and the Workplace Shell and its applications, including IBM Works,
demonstrate several aspects of OpenDoc technology today).


"Presentation Manager":  the underlying services used by programmers and the
Workplace Shell (see WPS) to provide windows, scroll bars, dialog boxes, and
other essential interface elements.


"Problem Management Record":  a number assigned by IBM to track a
customer-reported problem.  (Example:  "I have opened PMR Number 9X534; please
reference this number if you call again.")


"Point-to-Point Protocol":  a standard communications method used to carry
network protocols (especially TCP/IP) over a modem, ISDN, or other serial
connection.  Although PPP requires more overhead than SLIP, it is considered
its successor.  PPP is available, free of charge, for OS/2 Warp's Internet


"Remote Initial Program Load":  the capability to boot (start) a PC (load its
operating system) over a network.  See IPL.


Refers to the ability to run Windows applications alongside OS/2 and DOS
applications on the Workplace Shell (see WPS) desktop as opposed to the full
screen Win-OS/2 desktop.  (Example:  "Will this video driver support seamless


"Serial Line Internet Protocol":  or a means of sending TCP/IP network traffic
over a modem or ISDN connection.  SLIP is used when connecting to an Internet
provider (such as the IBM Global Network) using OS/2 Warp's Internet


"Symmetric Multiprocessing":  a set of technologies in which two or more
computer processors (CPUs) are managed by one operating system to provide
greater computing power to applications.  With SMP, processors are treated
more or less equally (with applications able to run on any or perhaps all
processors in the system, interchangeably, at the operating system's
discretion).  Simple MP usually involves assigning each processor to a fixed
task (such as managing the file system), reserving the single main CPU for
general tasks.  OS/2 for SMP provides true SMP capabilities on a variety of
systems, including those which are compatible with the Intel MPS
(Multiprocessing Specification) 1.1 standard.


"System Object Model":  the underlying design which allows applications
running on OS/2 Warp to be so tightly integrated, able to share data and,
indeed, runnable objects quickly and easily.  The Workplace Shell is the
largest and most complex OS/2 application based on SOM, but there are many
other applications which use SOM extensively (such as IBM Works, cc:Mail for
OS/2, Chipchat Wireless Communicator, IBM Workframe 2.1, DeScribe Version 5,
Mesa for OS/2, and more).  For programmers, SOM is fully compliant with CORBA
standards, fully distributable (over a network) without any programming
changes, and is true object technology, with inheritance, encapsulation, and
polymorphism.  SOM objects running on OS/2 Warp are fully protected from one
another and do not share the same address space.  SOM is one of the key
technologies in OpenDoc, is available on many other platforms, and has been
declared a U.S.  Federal Government open software standard.


"Service Pak":  see CSD.  Sometimes numbered (e.g.  "SP 2") to refer to a
particular Service Pak.


A company founded by IBM and Apple (with Hewlett-Packard also a major
shareholder) with a mission to create a set of object-oriented software
technologies, including the Taligent frameworks, for use by its parent
companies in their products (including OS/2 Warp).


"Transmission Control Protocol/Internet Protocol":  a protocol, widely
available and implemented across a huge range of systems, which allows
information to be transmitted across a network.  TCP/IP is the protocol used
by the Internet, and it is used over a SLIP connection in OS/2 Warp's built-in
Internet Connection.


"Universal Resource Locator":  standard notation for locating and accessing
information on the Internet which is used with a World Wide Web browser (such
as the IBM Web Explorer).


IBM's customized version of Windows, based on Microsoft's own source code,
which provides compatibility with Windows applications under OS/2.  Windows is
not emulated when it runs under OS/2; a real copy of Windows, only slightly
modified, is used.  OS/2 Warp is available both with and without Win-OS/2.
The version of OS/2 Warp without Win-OS/2 is designed to use an existing copy
of Windows or Windows for Workgroups (if present) to run Windows applications
under OS/2 Warp.  When running this way, that copy of Windows or Windows for
Workgroups is also often called Win-OS/2.

  Workplace OS

A set of technologies (not a product itself) which IBM is using to create
future versions of OS/2 Warp (such as OS/2 Warp for PowerPC) and other
operating systems.  Key to this set of technologies is the IBM Microkernel
(based on the Carnegie-Mellon Mach microkernel) and the ability to support
multiple "personalities."  Workplace OS technology allows IBM (and, in fact,
other vendors) to create portable, reliable operating systems which are easily
reconfigured to meet the needs of any buyer.


"Workplace Shell":  OS/2 Warp's most commonly used user interface which
provides icons, folders, drag-and-drop configuration, settings notebooks, and
other features necessary for user interaction with the operating system and
its applications.


"Extended Memory Specification":  a method used by some DOS applications for
accessing extended memory (beyond 640K) on 80286 (or better) processors.  OS/2
Warp can provide XMS memory to DOS applications.  See DPMI and EMS.
