SCO XENIX on a Priam ID-100 hard disk?

[sadler at ddnvx1.afwl.af.mil]

Okay, I give up.  I am having an awful time trying to reinstall SCO XENIX
ver. 2.3.1 on a Priam ID100-RC RLL hard disk drive.  It's a 386 based 20 MHz
system I inherited, and I decided to increase the swap space.  Bad Idea.

I can get all the way through the install process to the point of making the 
filesystems and entering the activation codes, but I invariably get the error 
message below when trying to boot from the hard disk to finish the process:

not a directory
/boot not found
Stage 1 boot failure: error loading /boot

Does anybody know what's wrong?  Aside from the small swap space, the system 
worked fine before I started my "improvements", so it's not a basic 
compatibility problem (though XENIX is not fooled by Priam's cylinder/head 
remapping like MS-DOS is.  I have to give the disk's true characteristics to 
XENIX, i.e. 1156 cylinders/7 heads and _not_ 581 cylinders/14 heads, or the 
bad tracking gets really screwed up.  If you have a Priam disk you know what 
I mean.)  I suspected hardware trouble but I can get MS-DOS (bleck! :^) to 
work fine.  Unfortunately, the hard disk manufacturer seems to have bitten 
the dust.

What hand-waving is required here (aside from getting another hard disk)?
Anybody with the proper formula?  Please respond by e-mail.

Thanks,
