Howdy Hackers,

I tried using the built in vesa driver for the djgpp graphics package.
It seems to not switch to graphics mode, but rather randomizes the
colors on my dos screen (so badly that I sometimes have to reboot to see
anything).

GO32=gw 1024 gh 768 nc 256 

I have loaded the bios into ram, and have set the vprmode to vesa with
their tsr program. Also, fractint 18.2 can use it at 1024 X 768 X 256
with it's supervga/vesa driver.

I am wary about randomly trying the drivers that came with the program.
I have settled (tentatively) upon the vga driver, but it seems to ignore
the gh 640 gw 480 autoexec driver options, and maxx and maxy are
reported to be 320 and 200 at run time (at least I have 256 colors).

My card will allegedly do 1280 X 1024 X 256, and I seem to be able to
harness only 1/20 th of it. Does anybody out there have a Diamond Viper
(Weitek P9000) card, and how do you get it to work?

If anybody is interrested, I have obtained 400+ pages of technical specs
from Weitek in hopes of one day performing high/true color direct video
memory writes for ultimate speed as I have done on a comparatively
simple Boca VGA/X2 card. If anybody is aching to write a driver for this
beast, I have the technical scoop.


Thanks,

        Brian
