- 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!
