Most vendors have technical reference manuals that give you this sort of information. I have paid from $0.00 (Hercules last week) to $50.00 (Video 7 VEGA VGA 2 years ago). You might also want to contact VESA (Video Electronics Standards Association). They have standardized many of the "Super VGA" (more common than "tweaked") modes and how to access the pixels in these modes. Ask for their spec on SUPER VGA BIOS EXTENSION. Many of the older boards will not support the VESA standard without a ROM upgrade or a TSR program but nearly all the new ones support at least one of the VESA modes (800 x 600 x 16 colors). Another possibility is to purchase a graphics library that supports those modes. I wrote the graphics library that comes with the Zortech C/C++ library and it currently supports the VESA 800 x 600 x 16 color mode. Some of the other modes are planned for the future (some time after I get the UNIX port done).
