Subject: Using your Zip drive as a floppy drive

If you don't have the external floppy drive but you have a Zip drive, you
can use it as one. All you need is a $15 utility called ZppA. It allows you
to boot from a Zip disk. It's especially useful when you install SOFTPAQs or
if you want to install a new operating system, like Windows 95 OSR2.

This is an extract of http://www.blueskyinnovations.com/zppa.html:

What is The ZppA?

The ZppA allows you to use your Iomega Parallel Port Zip Drive as if it 
were a high-capacity floppy drive.

It will even allow you to boot from a Zip disk!

The ZppA is installed in the Master Boot Record (MBR) of Drive C. It is 
loaded before the Operating System and will automatically detect a 
Parallel Port Zip drive that is connected. If a Zip drive is not 
connected, The ZppA will still be installed so that you can connect up a 
drive later.

The ZppA will then configure the Zip drive detected as either Drive A or 
Drive B.

If the Zip drive is configured as Drive A, you will be able to boot from 
it as if it were any normal diskette. We have even successfully 
installed full Windows 95 on a Zip disk configured as A: and boot from 
it.

The ZppA will occupy between 4 to 5 KBytes of main memory when it is 
loaded.
