VGA Problem about 440bx chipset

umm. that part was unfortunatelly a bit of black magic.

make sure you have mouse on your ps2 port. win2k would freak out for some
reason if it did not.

also you may want to edit the win2k config files not to display that
prompt but go straight to win2k and see if it helps.

then you may want to play with timings in the IDE driver in bochs..
