Quoth Release Notes for Xenix 2.3.1, page A-14, "Some hard
disks have more than 1024 cylinders.  At this time, XENIX
supports a maximum of 1024 cylinders."

Uh--oh.

Call SCO and ask them why they didn't tell you that in the first
place (there may be a reasonable explanation, like you set it up
with 612 logical cylinders with twice the sectors per track or
some such... I've seen that, but I think the controller has to
support that somehow).
