I think that it is the other way around. PC MotherBoards are going to request a VGA mode that needs to be supported. This VGA mode is only used until the OS loads a graphics driver. Linux uses VGA/VESA for text mode console so that is going to be needed unless we have a Kernel driver for console mode. OTOH, an embedded system that didn't boot with a VGA mode is going to need to contain the code needed to load the driver to start up the graphics card. Such systems probably wouldn't even have a VGA/VESA Video BIOS.
Sooner or later, we're going to have to get back onto our VGA implementation. I'm envisioning a system that does not directly convert text to graphics in the video controller. Rather, we emulate that by converting to graphics either as the text is written to memory or converted in bulk on a periodic basis (at least 10Hz would work very nicely, but we could do a lot better very easily). What the video controller scans out, then, is raw graphics. We can make that resolution anything we want. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
