If the video-bios does support only the VGA modes (13 or how much they are in the standard) then one can pre-generate the video controller binary & store diffs for various modes. This might be less, than a mode table + algoritm to generate the binary in runtime. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
