This solution fixed a similar problem on an old win2k pc I had. The
_solution_ kind of sucked because APM stopped working. You got _it's now
safe to turn off your PC_ instead of a clean shutdown, I couldn't suspsend
(not that windows ever suspends and recovers well enough to be trusted),
etc. If you are booting into windows just to play a game, and then
rebooting, these problems probably won't bother you, and for whatever
reason I can't describe, you'll get a better IRQ distribution.

This didn't break anything in my case. You just right click my computer,
got to properties, go to hardware, then to device manager, right click on
computer and go to properties, do reinstall driver, pick from list,
and then choose standard PC.
One time, when messing with my mom's older P-II ibm, I tried to go the
other way with win2k (from standard pc to acpi ready something pc)
it never again reboot until i reinstalled everything. wacky.

I don't know where you would define this option during install; I don't
remember seeing that.
