There should be no performance hit when in "Standard PC" vs "ACPI PC". The only thing that driver really does is tell the OS who controls the resources of the machine; the OS or the BIOS. The only slow down that could be a result of switching drivers would be with having two major devices in your machine sharing the same IRQ. Say your video card is sharing the same IRQ as your sound card or NIC. THAT would cause a few slowdowns/problems.

I have been using the "Standard PC" driver ever since I moved to Win2K because I HATED the fact that with the system would automatically install and use the "ACPI PC" driver, ALL my devices would share the same IRQ. It must be an issue of whether or not the BIOS supports MPU V1.4 becuase my new Epox 8DRA+ does support it and will allow the "ACPI Uniprocessor" driver to work where the last 3 MB I had did not (all ABIT). I have been wanting to use the "ACPI Uniprocessor driver for quite some time.

One other thing that you will notice between the "Standard PC" and "ACPI PC" drivers is that when you shutdown the system, you have to manually power off the machine while in "Standard PC"

BTW you can FORCE Win2K to install a specific "PC" type driver during the install process. At the screen where you see "Hit F6 to specify a special hardware driver", you can hit either F5 or F7 and it will ask you what driver type to install. Works great.

Anything else?
