This is a ZIPped ATR that is suitable for use with
Atari800Win PLus, SIO2PC, or APE.  It unzips out to a
16 megabyte ATR file.  It is set up to boot
x33a.dos which is best for use with the emulator.  If you
are using APE or SIO2PC you will have to perform the following
two steps before booting this image:

Step #1  At the command prompt type "BOOT X32GX.DOS"
Step #2  Edit the STARTUP.BAT file and change the
         entry that says "SHELL33A" to "SHELLGX".

Additional configurations instructions can be found in
the ATOS web pages and WWW board.
