That's what I thought as well, since it *works* (yeah, and under the 2.2.3
I'm typing at as well) but that's simply not true.  Somewhere earlier along
this thread someone commented that this was because messdoss/xenix
coexistence couldn't be supported in such a case, so sco decided not to
support *any* use of >1024 cyls. Agh.  Note: *support*.  Doesn't mean
it don't work: just make sure that 1) you don't put messdos on the
same disc, 2) change back down to a <= 1024 cyl disc before calling
sco support.  Arrgghh.

Yep, Go look at your release notes

	"Some hard disks have more than 1024 cylinders.  At this time,
	 XENIX supports a maximum of 1024 cylinders."

Sigh.

Oi, Rosso, whatcha gonna do about this ? :-)
