Finally, could you please put your source to the FreeBIOS CVS ??Usually we are unsure if our version matches yours, you know, things like this make a lot of trouble.
Let me know if any SIS engineers need CVS commit permissions. Ronald and Johan (original STPC BIOS author) already have CVS commit permission.
Please put me (ollie@sis.com.tw) and K.M. (kmliu@sis.com.tw) on the list.
P.S. Jeff, could you review the sisfb for us ?? What are we missing from the driver for this special purpose ??
I'm not sure about the oops yet, but with respect to VGA BIOS init: I've been looking through it already to see if I can get the 6326 card going with sisfb.
The main thing that appears to be missing is memory configuration. Just like linuxbios and DRAM init, the video card's memory timings must be setup, and video memory sized. There are many parallels between what a VGA BIOS does to initialize a video card, and what a PC BIOS does to initialize a PC.
For intergated VGA in SiS 630:
dram timming of VGA == dram timming of System dram sizing of VGS == How much you want, you get it.
Beyond that, there may be other differences which are not immediately apparent from my reading of the specs. For example VGA emulation mode may need to be initialized before VGA registers/functions work at all.
What ?? Could you be more specific ??
