SCO XENIX will support the following video configurations:
1. No video adaptor (COM 1 as serial console)
2. One video adaptor
3. Two DIFFERENT supported video adaptors
If two supported video adaptors are used, one MUST be a monochrome
card and the other MUST be a color card (either CGA, EGA, or VGA).
The adaptor configured as primary (determined by hardware settings)
will display all the bootup messages. Prior to SCO XENIX 386
Operating System Release 2.3.0, the primary adaptor will also
control the first half of the total multiscreens allocated in the
NSCREENS kernel parameter. The second video adaptor will control
the last half of the allocated multiscreens.
In SCO XENIX 386 Operating System Release 2.3.0 and later all
configured multiscreens will go to primary video by default. To
allocate multiscreens to the secondary card, use the command
vidi(c). For example, if you are using a monochrome card as your
secondary video card and want tty07 associated with that card, you
would use the following command:
vidi mono < /dev/tty07 > /dev/tty07
It is necessary to activate the new screen by typing <alt> F7
before any output will go to this screen. Placing this line in
the file /etc/rc.d/8/userdef will cause the command to be executed
every time the system enters multi-user mode.
Repeat this process for each multiscreen you want associated with
the second video card.
Beginning with SCO XENIX Operating System Release 2.2.0, kernel
error messages are directed to the current multiscreen (or serial
console if no video adaptor is present), regardless of whether
the active screen is controlled by the primary or secondary video
