What about a carputer which need to be able to display graphics (X or DirectFB)? can I skip the VGA bios in such setup altogether? I'm talking about VIA EPIA M-II so I am not sure if two LB "drivers" you mention below (RageXL and GeoDE) can work? > > > > > Linux kernel to use framebuffer but I guess that original VGA BIOS is > > > not really needed for that, just to be able to "control" LB/FILO from > > > the local console, right? > > Depends.
