VGA256.BGI a reverse-engineered BGI driver for Designer VGA
This is an update to my BGI driver ORCHVGA.OBJ. I now fully support
the BGI file format. This means that a programmer can choose either
a dynamically loaded BGI driver or a linked-in OBJ driver.
I separated the autodetect component of my driver from the BGI file.
It is found in VGAEXTRA.OBJ. This allows you to write your own autodetect
function to replace mine (mine can't determine if you have a Designer card).
P.S. If I can ever find the time I would like to try this driver on
Turbo Prolog. If anyone succeeds let me know......
