There are two controller address available.  I would think the problem
would be that most IDE controllers don't give you a choice about the
IRQ.

UP to four disks can be supported with ease in NetBSD/386bsd/FreeBSD.
RIght now, the SCSI and ISA hard drive controllers are separate and all
can have multiple drives.  SCSI controllers CAN (maybe not well or
reliably, but theoretically) have six drives...  DOS can only see the
first two.
