Well, someone else can fill in the specifics since I don't remember the
BIOS call functions off hand but if you're using an EGA,VGA video card you
can call the INT ??h (10h?) that normally initializes the screen mode with
a value that tells it not to clear the screen.  Pick up any Assembly guide
for the BIOS calls and look it up.  Unfortunately, CGA and I believe MCGA
modes always clear the screen and cannot be avoided.  In these cases you
have to either already be in graphics mode, or reprint the text.

Hope I was of some help, you can mail me for more info and I'll take the
time to look up the actual values.  Although someone will probably post them
