I suppose it's always possible that Seagate will come across with
an SCO Xenix SCSI driver for your 286 that will actually work, but I
wouldn't want to bet my bottom dollar on it.

Unless you're adept at writing your own device drivers I'd suggest that
you will need a 386, an Adaptec 1542 (methinks is the #) SCSI controller,
and a suitable SCSI hard drive (I know that the 330 meg Priam works, and
I'll be trying a miniscribe 9380S soon), as well as SCO Xenix 2.3.1GT
or later.  Note the "GT" version.  Non-GT versions do not have SCSI
support.  There are also reportedly other SCSI controllers out there
(notably a new Western Digital) with Xenix drivers, but they're not
yet on SCO's supported list.

Your Xenix release notes are your best reference.

See above.  I am not aware of a 286"GT" version of the SCO Xenix o/s.
