You copy the font to plane 2 of the video card memory (mapped at A0000h) and set the font offset to 0 (or where ever you've stored the font in video memory). VGA cards work the pretty much same way so it's not too hard to find documentation on the WWW on how to do this. Use Ralf Brown's PORTS.LIST to figure out what applies to both EGA and VGA and what only applies to VGA.
