Hello.

I would like to use 256 grayscale colors with djgpp.
Is it possible? and are there any libraries to do so?

I tried allegro2.2 with GFX_ET4000 gfx_mode, but I could only
obtain 64 grayscale colors.
e.g.
set_gfx_mode(GFX_ET4000,640,480,0,0);
for(c=0;c<256;c++){
  pallete[c].r=c;
  pallete[c].g=c;
  pallete[c].b=c;
}
These palletes seem to repeat 64 grayscale colors for 4 times
with my video card, ET-4000/W32 2Mram.

Thanks.
