I am still looking for any information on setting SVGA modes, mainly 256 color, with out using the BIOS. This is by definition chip-set specific, and is often video card specifuc. I was also wondering how OS/2 handles this (do they load the video BIOS?) I've had better luck with the chip-set technical manuals than unassembling the BIOS, but there has to be a better way.

An answer:
Have you ever seen John Bridges' VGAKIT? It contains code to detect and
bank switch many (all?) of the VGA chip sets.
A question:
Where did you get chip-set technical manuals? If you got them from the
manufacturers, could you post the names and addresses?
