What are the standards most video cards follow from a programming stand point, ie. setting the video mode? Where can I find out more info on how to use these standards? I know DirectX will work with Windows programming, but I'm also interested in knowing this. Choose a path: path one or path two Edited by - Densun on 11/24/00 7:21:18 PM

They''re aren''t any, or at least what ''standards'' existed in the DOS days, changed constantly and varied from card manufactor to manufactor (because they all felt they had the dominating product and felt they should get to decide the standards)

mode 0x13 (19d) is good ole'' VGA mode, 320x200x256, Tricks of the Game Programming Gurus probably covers all this stuff.


Eventually something called VESA came out (and it has at least 2 revisions) that provided some standards, but not every card complied to all the VESA requirements.

Sooo you more or less needed to write a blitter for each type of video card.
