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...
