Win2K and funky IRQ assignments...
This is a discussion about Win2K and funky IRQ assignments... in the Windows Hardware category; Hi. . . Hoping someone might know something about a peculiar little phenomenon I've seen at work. With certain hardware configurations (probably the motherboards, but not sure), Win2K hands out IRQs beyond 15, such as IRQ 23, IRQ 28, and IRQ 30.

I'm thinking it has something to do with virtual IRQ assignments, but I don't know... it happens whether or not ACPI is disabled, too.
Any thoughts?
Thanks,
Kevin

If its not causing problems, its best to leave it alone.
MPS Uni/Multi/Acpi Uni/Multi assign higher IRQ's like that. Also ACPI assigns IRQ's for devices on the same IRQ. This is the way it should be. Also if your installing Windows 2000 on a new machine update your mobo to the latest bios, it's likely that the bios has been updated with ACPI support.
