More on Everex EVGA card in Xenix 2.2.3 (386/AT)

[David Schachter]

I set the EVGA card to connect to a CGA monitor I have lying around.  Told it to
boot in CGA mode.  Machine boots ok.  Xenix boot gives me ":" prompt.  I hit
return (this is using the 2.2.3 installation floppy, of course.)  Control is
transferred to Xenix (presumably).  CGA monitor loses horizontal sync; NEC
Multisync +, which was wierded out by the 15 kHz CGA, syncs up, with same bogus
screen as before: accented e's where blanks ought to be, wierd characters where
installation script outputs normal stuff, bottom line of screen contains upper
half of accented e's, lower half cut off.  Made copy of installation floppy and
added "stty C80x25" in /etc/rc.  Didn't help.  Xenix is running but it is
printing the wrong characters (or, more properly, it has set the EVGA into a
funny mode.)

Note: there is no way to tell the card to be a plain-vanilla CGA.  However, I
have disabled its "autoswitch" circuit.

Question: why is Xenix 2.2.3 ignoring the switch settings on the EVGA card? 
Don't those get translated by the ROM BIOS into data around 0:400, which Xenix
should look at?  

Question 2: Xenix 2.2.3 is apparently insisting I have a Compaq VGA, even when
the EVGA is strapped to be an EGA with a CGA monitor.  This causes the monitor
to lose sync when Xenix switches the card to VGA mode.  Can this damage the
monitor if left this way?
