[comp.os.msdos.programmer] VGA font programming

reid@iris.ucdavis.edu (Christopher M. Reid) (03/14/91)

I need help in using a standard VGA graphics adapter to redefine the
fonts that are used to display to the screen.  I want to define a
second character set and define some special characters.  I am
currently using BIOS calls (fn 10 hex) to load defined characters in
Borland C++.  The main problem is that the screen flashes on every
font load call, and I need to be able to define the new characters one
at a time.

Can this be done by direct memory manipuation?  If so, what addresses?
Or am I using incorrect BIOS routines?

Please HELP!

Thanks very much,
Chris Reid
