OK.  Wow -- I can get 1024x768 x 16 million colors.  I've set:

set GRX20DRV=vesa gw 640 gh 480 nc 256

but I still get 1024x768 and 16million colors.  I'm using GR_custom_graphics
mode.  Actually, I'd like to cut it down about 800x600 and about say 16bpp
giving 32k or 64k colors.

Little bit too hi-res for my 15" monitor.

Maybe I have to set GRX20DRV and mention bpp, and use GR_custom_bpp_graphics
instead?

Also, with 640x480x256 the pictures look real splotchy.  Maybe it's in palette
mode?

Thanks for the help,

   Donn
