[comp.os.msdos.programmer] Super VGA detection

I would like to use the 800 x 600 16 color mode reliably on Super VGA
cards. From the Brady book on Super VGAs it appears that the memory is
organized the same way for all these modes (just as in the 640 x 480 x
16 colors VGA), and the only card-specific difference is the mode number,
with an emerging standard of 6AH, but lots of variation on the cards 
currently on the market. 

There is code in the book to recognize most of these cards, and I am
entering and testing it. But really this is ridiculous. Is there any
commercial or shareware program that achieves this? I.e. test the type
of the Super VGA card and either tells me the manufacturer or the capa-
bilities, in particular what mode number to use for 800 x 600 x 16 colors?

Please email any info, I'll post a summary.

Thanx!
