OK, here's the situation: I have two monitor (VGA and mono) and want to write
a TSR that will display text on the mono monitor without disturbing the
VGA screen.

I have tried using BIOS interrupt 10, function 00 (set video mode).  This will
work when changing modes to anything but 7 - the one I need.  It switches to
mode 0 when I try this.

I need to be able to do three things: clear the mono screen, write text to
it, and scroll up one line.  As usual, I would like the easiest and most
efficient method - other than writing directly to video memory.

Any suggestions?  Do I need to do something else to change video modes with
the above listed BIOS call?

Please e-mail me...

Thanks!
