Subject: High res modes with djgpp.

Hi,

I have loaded the latest version of djgpp from oak.oakland.edu and
am having problems getting it to go into any video mode other than
320x200.

I have set go32=driver c:\djgpp\drivers\vga.grd gw=640  gh=480 nc=256.
The driver physically exists at that path. I have also noticed that in
the DJ doc's that some times the driver path uses slashes '/' and that
at others, it uses backslashes '\'. Which is right?

I have tried to GrSetMode to GR_default_graphics, GR_biggest_graphics,
GR_height_width_graphics and every other mode listed in graphics.h 
with the result always being 320x200.

I have tried every hardware specific driver (paradise, genoa...) and
gotten crashes on all but vga.

I have tried to remove the set go32=driver to rely on the built in
driver. It destroys my color palet, complains about a graphics mode
error, and forces me to reboot to see my screen again.

I have tried to load my viper vesa driver with vprmode vesa or not
and it makes no difference.

I have tried to load msdos 6.22 emm386 with +-noems, +-novcpi, on, off,
auto, +-ram, +-v, +-frame=none and practically every combination of 
these switches.

I had it working on the release that was current 6 months ago, and
can't get it to work now.

Additionally, I have tried to figure out how to use djgpp/contrib/libgrx,
but can find no documentation on it. It has a vesa driver which seems
to be just what I need. I have also run DJ's vesa test program (I think
from go32 directory) and it lists 101 vesa modes that my hardware
supports. Viper diags report good working hardware, and fractint
works at all vesa resolutions up to 1024.

Can someone post a copy of a working config.sys, autoexec.bat, and a
skeletal C program that actually works with any high res mode.

Thanks 1E6,
