Okay, I've lost an IRQ line. I changed the IRQ setting on the AHA1542CF
to 9, and it works. Clearly, IRQ 11 is dead for some reason. It isn't
due to a device conflict -- there were no other devices in the bus which
could conflict. (Just the AHA1542 and a PCI video board). The BIOS has
no IRQ assignment functionality. (This is an old P133 Micron board).
At some point in the near future, I'll test the motherboard by putting a
different CPU in it, and test the CPU by putting it in to a different
motherboard, to determine whether it is a trace on the motherboard vs a
part of the CPU that failed.
Thanks for all of the suggestions from everyone -- unfortunately, it
really has turned out to be a hardware failure.
A last question that comes to mind: At this point, what would you do?
Use the board and avoid IRQ 11? Replace it? (I'm assuming here that the
motherboard, not the CPU, failed. If the CPU is going bad, I want to dump
it before it corrupts data).
