The problem with the ATI bus mouse is that it is not a Microsoft INPort Bus
Mouse. ISC's driver does a signature check to make sure it is talking to an
honest to GOD INPort chip. This fails of course with the ATI bus mouse. It
took me two weeks of digging to find this nasty. Another problem with the 
ATI Video Wonder and a Micronics 20Mhz cacheing motherboard is that neither
a warm boot nor a hardware reset will work. You get a machine that won't
reboot. The ONLY way to reboot this combination is the big red switch. I
never did solve this one. Thankfully, GOD stepped in at this point and
rebooted my system with a few mega-amps of lightning and my insurance company
bought me some nice new 33Mhz hardware.-)-)
