Actually, I don't know if vfont ALSO works on the EGA, but then I have never
tested it on an EGA.

Anyway, if you want your character sets to work on both EGA and VGA you 
will have to suffer with the EGA charater sizes. Since I haven't typed in
any of the listings I have I can't include then with this file but I can
give you an excellent reference for this sort of thing.  Try
    "Programmer's Guide to PC & PS/2 Video Systems" by Richard Wilton.
     published by Microsoft Press ISBN 1-55615-103-9
Be forwarned though, this book is for people that are at least slightly
familiar with assembly language, but even if you aren't the code that is
included is in the form to be included with Microsoft C (I suppose TC also)
as subroutines.

For those that are interested this book give some wonderful tricks to do
with the display and goes in depth into programming at the hardware level
and is a great technical reference.
