my information here just comes from the fact that I am offered only three choices of resolutions after installing the CD drivers 640 x 480 x 256 800 x 600 x 256 640 x 480 x 65536 this may just be a driver problem, after all 800 x 600 x 65536 requires 800 x 600 x 2 = 960000 < 1 megabyte of video RAM so it seems like the higher resolution at 65536 colors should be possble
