In the release notes (if I remember correctly; they're not handy right
now) it explained that some hard disk controller boards have the
ability to work on other interrupts.  It went on to say that hardware
mods to the board may be required.

The second controller can also be SCSI.  This is probably a better
move, because you don't have to fiddle as much with crufty hardware
mods.

I think Tandy has done some hacks to get SCSI boot devices.
