Does anyone have any useful information on defining alternate characters
on the EGA by using the higher resoultion graphics mode? I have seen
this done on the color graphics adapter while in graphic mode. I have
also seen a demonstration of this on an EGA by a program called CHARGENI.

The end result of the information which I receive will be used to create
a "replacement rom" for the WordMarc program. These folks' program will
not operate properly on an IBM fitted with an EGA and monochrome moniter.
If I am able to redifine what the characters look like, then I may be
able to get WordMarc to properly display the scientific character set.

Does anyone have a copy of CHARGENI in source form or some other human
readable form (disassembled(?)) where I may be able to get some information
on they technique that was used? Specifically I am wanting to know what
registers need to be set up and what parameters need to be passed to
INT 10H to get this sucker to fly...

Thanx for any and all information which comes my way in advance.
