It should be just an ISA IRQ... I'm 99% certain the IDE on the multia
is NOT implemented in the SIO, but rather in the SMC super-i/o chip that
also has the serial, parallel, and floppy controllers (just like the chip
found in many PCs).

Even if the interrupts didn't work, we should be able to communicate
with the drive in polling mode, which is what autoconfiguration uses
