Is there a way for linuxbios to initialize the graphics hardware directly? besides making linux use the framebuffer directly on bootup. and maybe making filo use the framebuffer too.
If the hardware was standard then yes but each graphics mfg does it differently and its hidden by the VGA bios. Think of each graphics card as a graphics northbridge. You have to eanble all the right bits, turn on the video ram, etc. On 99% of graphics cards the info on how to do this is not known. So you have to run the vga bios to do it.

ugh!!!
and the vga bios is running at 16 bit mode? and its slow with all its timing loops and other stuff.
which graphic cards are in the other 1%?
hah! this is another argument for ogp. i have to start studying fpgas now. i need an open graphics card that boots at a fraction of the speed of current cards and boots straight into framebuffer mode.
