Video mode setup function tries to use all available video drivers to initialize video mode. It uses first it founds working. So if someone writes VGA driver then you can add it to queue and if VBE2+ is not available then it would try next driver, in this case it would be VGA driver. You can specify video mode to be 800x600 without color depth so it will use most colorful mode it finds. But if first adapter has 800x600x16 and second would have 800x600x32 then it would take first as there was valid mode. Other option would be to probe for modes and then select one. But this should be in script or in custom module code. Or gfxmode would be extended to allow multiple selections like 1024x768;800x600;640x480. Also there are starting to be lots of wide screen LCD's that should be somehow supported too. I think that Video API do not have any limitation on this regard. _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
