Xenix/386 2.3.1 on Monolithic motherboard

[Chip Salzenberg]

We recently have had occasion to install Xenix/386 2.3.1 on a 386AT system
based on a Monolithic System Corporation motherboard.

Or to try, anyway.

When booting the N1 floppy, everything works fine until the kernel is
loaded. :-) Seriously: at the boot prompt the keyboard works, and during the
kernel load from floppy the Caps Lock and Num Lock lights toggle correctly.
But once the kernel load completes, Caps Lock and Num Lock -- along with the
rest of the keyboard -- do nothing at all.

The system has 1.5M of memory and an Adaptec ESDI disk controller; and it
worked fine with Xenix/386 2.2.3.  We've tried two keyboards -- one of which
is a gen-u-ine IBM AT keyboard.  We even got a replacement BIOS from
Monolithic.  Nothing has helped.

Is there anyone who has Xenix 2.3 and a Monolithic motherboard living in
harmony?  What's the deal?  Please, help us out.

(Post replies if you like; other people may have Monolithics.)
