That's the problem. I have plenty of free IRQ's...but, AFAICR, this old
bios doesn't let me say anything about what to do with them. I can't
assign IRQ's to PCI or ISA.

I still think the above is my only chance, other than retiring these
boards. They're dual capable P90 boards with built in (never used)
AIC7870's.
