I don't know of one that does this but the one that I have looks for extended
drivres (which I don't have) so there must be drivers someplace, also the gif
viewer that I have allows one to use a "BIOS mode" so what you need to do
is find the mode number of extended nodes of your card (On my ATI VGA wonder
65hex is 1024x768x16 so I type m [for mode] 12 [for BIOS mode] then 101
[101dex=65hex] and give the program the dimentions.  That's how I do it),
the only problem is this is very slow, but its the only way I know how.

GIve it a try.
