From the DJGPP FAQ list (available as faqNNN.zip from the same place you
get DJGPP; NNN is the version number):
10.4 Q: I looked into cbgrx103.zip, but couldn't find the driver for my
Mucho Extra Perfectum SVGA card.
Q: The driver for my SVGA doesn't seem to work.
A: Most current SVGA adapters are VESA-compatible, so try the VESA
driver built into go32 first. Do not define any driver in the
GO32 environment variable (so that go32 will use its internal
driver) and try to run some graphics program. (You might want to
run it first with the VGA.GRD standard VGA driver, so you will
know how the ``correct'' display should look like.)
For some cards the updated versions of their drivers are in
grx103m1.zip maintenance release of GRX, so if the above doesn't
work, download that file and look for a driver suitable for your
card.
If the driver you need cannot be found neither in cbgrdXXX.zip
nor in its maintenance releases, or don't work right, try
anonymous ftp to omnigate.clarkson.edu, directory
/pub/msdos/djgpp/pub. There are some contributed drivers there.
There is also a program called DISPLAY which includes some
additional graphics drivers. DISPLAY is available as
dispNNN.zip on SimTel mirrors in the graphics/ directory.
10.5 Q: I've heard that the built-in graphics driver is a VESA driver,
but it doesn't seem to work on my Acme SVGA/DeLuxe with on-board
VESA BIOS Extensions.
A: With some SVGAs, the built-in VESA driver in DJGPP 1.12 will work
reliably only if you explicitly set the number of colors to 256,
like this:
set GO32=nc 256
If you want non-default resolution, you can set it too, like this:
set GO32=gw 1024 gh 768 nc 256
If this still doesn't work, then maybe your card isn't as
VESA-compatible as it claims to be. You can make it compatible
by installing the UNIVBE TSR program. It supports many of SVGAs
currently on the market and has a very good record of VESA
compatibility. You can find UNIVBE as univbeXX.zip on any SimTel
mirror in msdos/graphics directory.
