Hi Rupesh. Just for completeness, there's a good documentation regarding
the initialization of graphic cards here . Unfortunately FreeVGA
relies on the VGA BIOS to initialize the card -- which I know is not
your goal -- but in the other hand does not require any knowledge of
proprietary hardware information.
BTW, anyone here already had some success with FreeVGA lately? (sorry
for hijack your thread, Rupesh :)
