I'm interested in defining fonts (for foreign alphabets) that can
be displayed by the Video Bios on my IBM-PC-compatible.  I understand
that IBM created a hook for substituting a user-defined font in
place of the defaults associated with ASCII 128-255: i.e. some pointer
in the BIOS that you just redirect at your own font bit maps.

Does anyone know (or know how to find out) how this is performed,
and know how the fonts are formatted? Any successes out there?
(My copy of the Duke Language Toolkit didn't work out of the box,
but I haven't given up on it yet!)

I actually own a Corona PC-400 which has a higher res (400l) display,
so I may have to jigger things anyway, but my tech manual says almost
nothing on the subject.
