From: Jeff Hurlburt (in II Alive, 1996 plus updates)

001- What does error #___ mean?

Error Codes

     Codes are in hexadecimal and are listed in numerical order. Except for a few IIgs System Failure codes, the system or sub-system reporting the error is shown along with the error description.

     Most IIgs tool set error 'descriptions'-- like divByZeroErr-- consist of just the error name as published in the Toolbox References. When such an error is reported, the first two digits identify the Tool Set; the last two identify the error# (sometimes this identifies the individual Tool involved in the error). The name and number of each Tool Set which reports errors is identified in the listing by labeling the first error in each Tool Set group.

     Many of the descriptions for 00xx codes refer to GS/OS errors. Usually, these codes have the same (or a very similar) meaning as ProDOS 16 (P16) codes, SmartPort codes, and 8-bit ProDOS 8 (P8) Machine Language Interface (MLI) codes. When there is a significant difference, other meanings are shown.

Note 1: Thanks to information supplied by David Empson several early System Failure Code messages (e.g. "File map destroyed") are now considered to be suspect as to accuracy. Yes, some kind of error has occurred; but, as David points out, the messages seem to have been incorrectly copied from Mac with no particular regard to relevance on the IIgs:

     For example, all the errors referring to "Can't load a package" make no sense - the IIgs doesn't have any such thing as a package (but early Macintosh system software does). Here is another big clue: error $30 is allegedly "Please insert disk (File Manager alert)".  There is no such thing as the "File Manager" on the IIgs, but there is on the Mac."-- David Empson

Basically, it appears that the faulty messages function as defaults (place holders) when more accurate third-party messages are not supplied. The suspect messages may appear; so, they remain in this listing; but, now they are marked.

Error messages marked ** indicate a System Failure message considered to be suspect.

Note 2: Error messages marked ****  indicate that a more detailed discussion is available in Question 004.

002- How do I activate the IIgs Diagnostic Self-Test; and,
     what does Self-Test Error Code ___ mean?

     The IIgs self-test is activated by holding down Open-Apple and Option and turning ON the computer. Or, with the computer ON, you can hold down the Open-Apple and Option keys and do a Reset (press Control and Reset). 

     During the test, the test number (in hexadecimal) is visible on the bottom of the screen followed by six zeros. After all tests are complete, a continuous 6 KHz one-second beep sounds and the screen displays a System Good message.

     If a test fails, the screen immediately displays a message "System Bad:" followed by an eight-digit code (in hexadecimal) on the lower left hand side. The code is also displayed staggered in the upper left hand area to help you read it in the event of a display RAM failure. In case there is a video failure, the code is also sent to the printer port.

Example 1: You get the message "System Bad: 05020000"

This indicates failure of Test #05, the Fast Processor Interface Speed Test. The "02" says that the FPI got stuck in Fast mode (i.e. it could not switch to "Normal" Slow speed when asked to). Test #05 does not use the last four digits.

Note: If a ZipGS accelerator card is installed and not disabled
and DIP Switch 1-4 (Defeat Counter Delay) is not set OFF (the
default setting), your GS will bomb on Test 05. John Link reports
that a TransWarp GS with the v1.5 ROM will fail the Speed Test.
In neither case does failure indicate any actual malfunction.

Example 2: You get the message "System Bad:  080200D4"

This indicates failure of Test #08, the Battery RAM Test. The "02" says that there was a problem reading and writing a test value to some address. Next, the "00" says that the test value was $00. "D4" says that the problem occurred with address $D4 in the Bat RAM.

IIgs Diagnostic Self-Test Error Codes

From: a list by Jeff Tarr, Jr., Apple IIgs Technical Reference
      by M. Fischer, and IIgs TechNote #095 by Dan Strnad

Error Codes are eight hexadecimal digits in the format 'AABBCCDD'. The first two digits (the "AA" part) always show the test number. The meaning of the remaining six digits depends upon the particular test. (There may be a few differences in the GS diagnostic self-test depending upon ROM version. For example, earlier GS's may not include Test #0C (AA= 0C).)

ROM Test:G
AA= 01   BB= Failed checksum      DD= 01: RAM error

Note: A ROM failure will also be denoted by "RM" in the top left
hand corner of the screen.

RAM 1 Test:H
AA= 02   BB= __: Bank number      CC= Bit(s) failed
             FF: ADB Tool error

Soft Switches:M
AA= 03   BB= State Register bit   CC= Read addr. Low Byte

Address Test:K
AA= 04   BB= __: Bank number    CCDD= Failed RAM Address
             FF: ADB Tool error

Speed Test (FPI):
AA= 05   BB= 01: Stuck slow
             02: Stuck fast

Note: If a ZipGS accelerator card is installed and not disabled
and DIP Switch 1-4 (Defeat Counter Delay) is not set OFF (the
default setting), your GS will bomb on Test 05. John Link reports
that a TransWarp GS with the v1.5 ROM will fail the Speed Test.
In neither case does failure indicate any actual malfunction.

Serial Test:1
AA= 06   BB= 01: Register R/W
             04: Tx Buffer empty status
             05: Tx Buffer empty failure
             06: All Sent Status fail
             07: Rx Char available
             08: Bad data

Clock Test:H
AA= 07   DD= 01: Fatal error occurred - test aborted

Bat RAM Test:F
AA= 08   BB= 01: Addr. unique    CC= bad addr
             02: NV RAM pattern  CC= bad patt DD= bad addr

ADB Test:J
AA= 09   BBCC= Bad checksum      DD= 01: Fatal error

Shadow Register:
AA= 0A   BB= 01: Text page 1 fail
             02: Text page 2 fail
             03: ADB Tool call error
             04: Power on Clear bit error

Interrupts Test (Mega II and Video Graphics Controller):
AA= 0B   BB= 01: VBL interrupt time-out
             02: VBL IRQ status full
             03: 1/4 sec interrupt
             04: 1/4 sec interrupt
             06: VGC IRQ
             07: Scan line

Note: There are reports that if a ZipGS accelerator card is installed
and not disabled, then, your GS may fail parts of this test depending
upon DIP Switch settings. Such a failure does not necessarily indicate
a hardware fault.

Sound Test:3
AA= 0C   DD= 01: RAM data error
             02: RAM address error
             03: Data register failed
             04: Control register failed
             05: Oscillator interrupt timeout

Note: If a ZipGS accelerator card is installed and not disabled,
then, depending upon DIP Switch settings, your GS may fail parts
of this test-- such as the Oscillator interrupt timeout check.
Such a failure does not necessarily indicate a hardware fault.

AA= FF (test number= $FF)  According to M. Fischer this shows a likely
problem with the Mega II chip because that test number is used only
during manufacturing testing.

0027 (ProDOS Error $27, ...)- In trying to access an apple SCSI hard drive hooked up to a GS I keep getting a $27 error!?

     This is an I/O error (input/ouput error).  It may indicate that there is a problem on the SCSI chain, such as a loose connector, SCSI ID# conflict, absence of termination at the end of the chain, or absence of termination power. Another possibility is that one or more hard disk files have become corrupted. Replacing a few files may fix things; or, you may need to repartition or, even, low-level re-format the hard disk. --Rubywand


0047 (ProDOS Error $47, ...)-  A "Duplicate pathname" error indicates that an attempt has been made to create a file which already exists or to rename a file to one which already exists-- i.e. the full pathname of a new or renamed file equals the full pathname of a file which already exists.

     Note that it is okay to have a file or folder named, say, "PICS" inside a folder named "PICS"; and, you can have files named "PICS" in different folders. Also, ProDOS will permit overwriting a file with a file with the same name so long as the original and replacement file have the same filetype.

     What ProDOS does not like is an operation which tries to _create_ a file or folder whose _full_ _ pathname_ is the same as an existing file or folder. For example, you cannot create a "GAMES" folder on /RAM5 (i.e. /RAM5/GAMES) if there is already a file or folder there named "GAMES"-- i.e. one whose pathname is /RAM5/GAMES.

     This error might easily occur when running a self-extracting file if the self-extracing file has a name which matches the name of a contained file-- a solution for this problem would be to rename the self-extracting file. A more general solution for duplicate name creation is to create a new folder and use the extraction utility (e.g. ShrinkIt-GS), instead of doing a self-extraction, to extract files from the source file to the folder. --Rubywand


0048 or 0049 (e.g. ProDOS Error $48, ...)-  Error $48, of course, means "volume full"-- you are out of space on the target volume.  Unfortunately, "volume full" is, sometimes, incorrectly reported when the actual problem is too many entries in the volume's main directory. (see below)

     A $49 "volume directory full" error means the main or "root" directory of the target volume has 51 entries and that an attempt has been made to create a 52nd entry. When it is incorrectly reported as "volume full" it can be very confusing to a user who CATALOGs the volume and discovers plenty of free blocks. The solution is to move some of the files in the main directory to folders. Only a volume's main directory has this low limit on number of entries. You can have many more than 51 files in a folder
. --Rubywand


004B (ProDOS Error $4B, ...)-  is an "unsupported (or incorrect) storage type" error. I suspect you are on the GS and that the game or whatever you are trying to run is supposed to have a forked file and now the program can not find it. This has happend to me when Dragging files around.  I recommend you recopy the game from your original disk, or re-unShrinkIt to the location you wish it be. If you believe a file may have a resource fork, avoid copying it with Copy-II Plus or moving it around on the GS des
ktop under an old operating system-- either process could result in losing the resource part of the file. --thedm


0051 (ProDOS Error $51, ...)- My 3.5 copy of AppleWorks 3 said "Error loading ATINIT" (on my //c, no less), so I tried using Copy ][+ 9.1 to copy ProDOS 2.0.3 over the top of the apparently broken copy of ProDOS 1.7 on the AppleWorks disk. It then ran the drive, cleared the screen, and informed me so: Error $51.  Does anybody know what the heck this means?

     The error indicates the directory is damaged.  You MIGHT be able to salvage stuff by doing a FILE copy, rather than a disk copy. --Jim Lowe


005A (ProDOS Error $5A ...)- Today, I discovered that one of my  Appleworks files had been overwritten by nulls. Luckily, I have a backup copy of that file. When I tried to delete the bad file and rename the backup I got ProDOS error $5A. Any insight into what this error message means and what I can do about it?

     Error $5A "block number out of range" (sometimes known as "baked bit- map") means there's a bit set in the bit map which corresponds to a nonexistent block on that volume. You could try taking a block editor and writing zeroes to the upper bit map blocks on the volume to cure it. --Randy Shackelford


0088 "network error"- Can anyone enlighten me as to why Copy-II Plus and ProSel-8 are unable to work with a network volume that the Apple utility (and plain-old Basic) has no trouble with?

     Simple answer. Copy-II Plus and ProSel-8 bypass the file system and do direct block I/O to disk volumes. This is verboten with server volumes, and you get error $88 for your trouble when you try. You'll have to use network friendly apps whenever you access the server volume. --Randy Shackelford


0201 "could not allocate memory" error- After using the installer to install the basic Sys6 over Sys 5.04 on my hard drive, I couldnt run a ProDOS-8 program. Before the ProDOS 2.0.1 sign comes up, it says "Error $201". I have more than 4MB! What's wrong?

     A $0201 error when switching to ProDOS-8 usually means some utility has left part of bank 0 or bank 1 allocated. You have enough memory free, but some particular memory that ProDOS 8 needs is not available.

     I have seen occasional $0201's after using Find File 1.0 (included with 6.0) before switching to ProDOS-8. --Dave Lyons


O512 (FATAL SYSTEM ERROR 0512) "badNdaTitleString"-- comes from FixAppleMenu (in the Desk Manager).  It means that one of your installed New Desk Accessories does not have a well-formed menu title string.  In particular, the required backslash (\) character was not found (make sure bit seven is off). --IIgs TechNotes


0681 and 0682 "bad event que" and "bad que handler"-- What do these error codes mean? How does the GS determine if an error is FATAL (as in FATAL SYSTEM ERROR)???

     The errors are 'Event Manager errors'. A key press and mouse button press are examples of "events". The errors indicate a record of events was messed up. One of many places this might occur is while you are typing-in text. "FATAL" usually means that System believes that things are so messed up in memory that restarting is necessary. Sometimes, "FATAL" means that System suspects that there may be a hardware failure. --Rubywand


0682 "bad que handler"-- My IIgs crashes with a Fatal Error $0682 whenever I have my expansion memory card plugged in and try to access the Control Panel. Also the Alternate Display mode seems to be missing and stuff won't boot. What's wrong?

     Error $0682 indicates a data structure maintained by the Event Manager is corrupted.  It is either the Event Queue itself, or something related to it. The most common cause for this is buggy software which has overwritten memory.

     The second most common cause is a faulty or incorrectly configured memory expansion card (or bad RAM on that card).  The event queue normally lives near the top of "fast" memory, so it is always located in the memory expansion card if you have one.

     Similarly, the list of items in the Desk Accessories menu is in RAM, so lack of Alternate Display Mode points to memory corruption of some kind. -- David Empson


08FF "UNCLAIMED SOUND INTERRUPT"-- A sound interrupt has occurred but none of the available interrupt handlers were willing to deal with it. The Sound tool set thinks this is pretty serious; so, it notifies the System Failure Manager and you get the error message. A possible cause is that the table of interrupt vectors or the pointer to the table has been messed up in memory. --Rubywand


0911 and 09010001 (FATAL SYSTEM ERROR 0911); was error number 0400 on ROM-00 machines. Fatal System Error 0911 and Diagnostic Self-Test error code 09010001 mean the same thing: You are experiencing an ADB "can't sync" problem which, usually, seems to relate to a hardware malfunction.

     See Csa2HDWHACK.txt for more discussion and possible fixes.

0C000003 GS Diagnostic Self-Test error/ Sound Test: Data register failed

There is one possible reason for this failure code being reported by the self- test: do you have a ZIP GS accelerator in the machine?  The ZIP GS, if enabled, causes the IIgs to fail some of its self-tests (only because the tests are relying on the speed at which the processor normally operates, and get confused because the CPU is running faster than expected).  If this is the case, you must turn off the computer and disable the ZIP GS by setting switch 1-6 OFF before you can run the self-test properly. --
David Empson


1102 "OMF version error"- When trying to launch some GS programs I am encountering the following error message:

Sorry, system error $1102 occurred while trying to run the next application. Return to launching application or restart system.

So, whats wrong with my IIgs and how do I fix it?

     Probably, there is nothing wrong with your IIgs. The "incompatible Object Module Format" error appears to indicate that your versions of the problem programs are, in some ways, not compatible with your operating system. Try launching the program from an earlier version of System or after booting an old "ProDOS-16" diskette. --Rubywand


1104 "file is not a load file"- I downloaded some GS Desk Accessories fine; but, when I try to use them I get this error. How come?

     Error $1104 is reported by tool $0B11 LoadSegNum (tool $0B in toolset $11). The error is reported if a check of a file's directory entry shows that the file is not file type $B3-$BE.

     If an NDA or CDA were downloaded and its file type were not preserved, then the file might be okay, but it would not be recognized as a load file. Try changing the file type ($B9 for a CDA; $B8 for an NDA).  An NDA named "File.Manager" by Jeff Hartkopf and Glen Bredon's ProSel-16 are two utilities that allow changing file type. --Rubywand


1301 "Unknown error $1301"- When I tried to open a file in Platinum Paint, I got this error message. What's wrong?

     I got the same error message when I tried to run Platinum Paint with Bernie ][ The Rescue on a G3 Power Mac. The error code refers to a missing driver; but, even if the correct printer driver is present, what Platinum Paint really wants is for the D C Printer Control Panel settings to be correct. --Jim Pittman


IIe Self-Test RAM error display: RAM   0 1 0 0 0 0 0 0- I get this  error message when doing a selftest on my //e enhanced boot up. What's it mean?

     The indication is a bad or loose RAM chip in the Bit 6 position. The RAM chips are in Row F at the front of the motherboard starting with Bit 0 and running to the right when viewed from the front of the computer.

 | Row

                   Front of Apple IIe

     If your RAM chips are in sockets, try removing and re-socketing the second chip from the right. If this does not work or if your chips are soldered in place, the chip is probably bad and will need to be replaced. -- Rubywand


RAMFAST-SCSI FATAL MEMORY FAULT CODE=08- Could it be a problem with my SSCI card?

     It looks like RamFAST thinks there is a problem with the on-board memory. Before calling Alltech, you might try pulling the board from the Slot-- do this only with GS power turned OFF-- and wedging-up and re-seating each memory IC. (This assumes the mem IC's are socketed.)  If you're not sure which IC's are memory chips, do them all. Re-seating the IC's may reestablish a pin- to-socket contact which has been broken due to oxidation coating on an IC pin or due to the IC working loose over time. --Rubyw


RamFAST MLI Error!
Command: 04-03 86 00 60 05 00 00 00 00
Status: 2F

     I have a new 530MB hard drive, and a ROM 03 GS with a RamFAST (ROM F, I think).  From the Ramfast utilities, I could do a low-level format on the drive with no problem. However, when I attempted to partition it, I saw the error message listed above.

     As it turns out, this drive has a place for a jumper documented to "Disable TI Negotiation." Before giving up all hope, I put a jumper in there. This apparently made it possible to partition the disk, and things look good now. -- John David Duncan


RamFAST: RAMFAST.SYSTEM "Incompatible configure.dat"- My 10 year old came to me this weekend upset because of something that's happened to his GS.  When he boots it up, he is getting a message about an incompatible configure.dat file, then ends up in the ramfast scsi utility!?

     If the GS ends up displaying the RamFAST.System screen, and "Incompatible ..." message, click on the error message to clear it and then click Options. Set these according to your system-- mainly, click TransWarp to "No" if you do not have a TransWarp installed. Probably, you will want Password, RomDISK, HD Backup, and Short Timeout set to "No", as well. (You can experiment with Short Timeout and DMA; but, for now, set them to "No".) The other options should be "Yes".

     Click Save, then Quit. If you get the <<BOOT>> prompt, click it. If you end up looking at a BASIC prompt, try entering PR#7 (assuming your SCSI interface is in Slot 7)  to see if the hard disk will boot.

     If either of the above gets you into the Finder where you can copy files, then you will have a way to make backups.

     To check that the config has been correctly written to hard disk you will need to turn OFF the machine. (i.e. from the Finder, do a Shutdown and then turn OFF the GS.)

     After 10-20 seconds, turn ON the computer and see if it boots correctly. If it does, fine. If it does not, you may have to reformat the hard disk. -- Rubywand


"CHECK STARTUP DEVICE" - Why do I get this message when I try to boot a disk?

     This error message usually means that there is no diskette in the boot drive, the drive door is not closed, or that the disk is not bootable. On a system which has several drives-- e.g. 3.5" and 5.25" drives and/or a hard disk-- the message indicates that no bootable disk was found on any of the drives tried.

     If you know that a bootable disk is present, the indication is a problem with the drive (see Q&A above) or with the drive controller (which may be a card plugged into a Slot) or with a cable connecting the drive or with settings which affect recognition of the drive with a bootable disk.

     The problem may be that the bootable disk is not detected because the IIgs Control Panel is not set correctly-- e.g. the Startup Slot is set below the number of the Slot associated with the drive and/or the Slot with an interface card is not set to "Your Card". Note: After changing a Slot setting in the Control Panel, especially for a SCSI interface, it may be necessary to turn Off the computer and do a fresh power-up for the new setting to be in effect.

     If the expectation is to boot from /RAM5 RAM disk, make sure that /RAM5 is initialized before copying files to it. (/RAM5 is normally automatically formatted as a ProDOS volume when you first power up; but, it will not have the required boot block unless it is initialized or unless you do a whole-disk copy to /RAM5 of a bootable disk.) --Rubywand


"NO BUFFERS AVAILABLE" error message.  What does this mean?

     This message often indicates that there has been an attempt to load into an area protected by ProDOS. For example, many old DOS 3.3 programs like to directly load a text message or lo-res pic into Text Page 1 ($400-$7FF), an area protected by ProDOS.  Running such a program under ProDOS would be likely to produce the "NO BUFFERS AVAILABLE" message. You can recover from the error via a CALL48888. --Rubywand


"UNABLE TO EXECUTE BASIC.SYSTEM" - Why do I get this message when I boot a ProDOS disk?

     BASIC.SYSTEM has been loaded; but, startup code has detected one of two conditions:

o- It did not find a $4C at $E000 (which it takes to mean Integer BASIC
   may be installed).

o- It did not find at least 64K of RAM.

     The usual reason for getting this error message is that ProDOS with BASIC.SYSTEM has been booted on a 48K or smaller Apple II; or, the Apple II has a faulty Language Card (try re-seating IC's on the card). --Sandy Mossberg, Rubywand


"UNABLE TO LOAD PRODOS" - Why do I get this message when I try to boot a ProDOS diskette?

     For a ProDOS disk to boot properly, you need a good copy of the PRODOS file. It can be copied from any bootable ProDOS diskette. Or, from IIgs System, copy the file named "P8" (in the SYSTEM/ folder) to your diskette and rename it to "PRODOS". --Adam Myrow

     The error message means that enough of boot track (e.g. Track 0) was read to tell that the disk is formatted for ProDOS; but, for some reason, the system file named "PRODOS" is failing to load. Possibly, PRODOS is not present on the disk or the file is corrupted or there is a problem with the drive which prevents reading the file. 

     If the disk boots okay from a different drive, this usually indicates that your original drive has dirty heads, may be poorly connected, has a problem with head alignment, or (5.25") needs a speed adjustment. If the disk is a 5.25" diskette created on a newer model 5.25" ("40-track") drive, it may be an HD (high-density) diskette. Standard Apple 5.25" drives cannot reliably read HD diskettes-- see the Diskettes FAQs page. --Rubywand
