   The guy was wrong.  I run a stock Unix port on my Deskpro 286 (which uses
the same interrupts as the portable 286), and it runs just fine.  Doesn't
use the BIOS, so the interrupts must be the same.  In fact, the behaviour
of the controller board must be identical to that in the AT, also.

   By the way, I forgot to ask the original poster why he needs another
hard disk controller for the 286:  the one that's in there will support
two hard disks.  I built a new daisy chain control cable and outboarded
a Toshiba 72 Mb. drive; works great.
