Switching display cards for xenix 2.2.3

[Mark Jeske]

I installed xenix 2.2.3 on a machine with an ega display card.  The monitor
seems to have died, so I put in a monochrome card and display and reset
the dip switch on the motherboard.  After the 'boot:' prompt the
system simply beeps.  The drive seems to be going so I assume xenix
is loading, but nothing appears on the display.  I can boot the dos
partition ok.  Any ideas?  How can I get back to xenix?

Thanks, Mark Jeske
