SCO Xenix 2.2.3 boot problem for HP Vectra ES/12 286 (with HP EGA)

[mjoshi at hpldsla.HP.COM]

I have a problem with booting SCO Xenix 2.2.3 on an HP Vectra 
ES/12 286 AT box. The problem occurs when booting from floppy
for the filesystem (N2) part of the OS. The screen blanks out
and the Vectra just dies. 

The SCO people claim that the problem is with the HP EGA 
monitor that I am using. They support the IBM EGA
card in the strict sense, although I do think they should be
compatible. I don't suppose the drivers are incompatible 
either, since the VGA card when used in the EGA mode does work.

I did try the fix floppies and they too did not work. Any one
tried this before and came across such a problem? I would 
appreciate it if someone has a solution.
