I'm not sure what you mean by "DOS video mode". Mode 13h? Pretty chunky. Problem is, when we get beyond the VGA modes, the cards aren't standardized, and the manufacturers aren't too free with the information. If your OS is capable of using BIOS, look into the vesa specs.

What I'd do for a "toy OS" is put the card in a 640 x 480 mode (easy to draw characters) - probably "linear frame buffer", if I could get it - *before* switching to protected mode, using the bios. I don't know if that would fit in with your plans, though...

If you plan to write your own drivers, taking advantage of "hardware acceleration" where available and all - Whew! Big job! But it *can* be done, of course, and Nasm should be a suitable tool...

Best,
Frank

320x200,8bpp,indexed ;-)

Very true :-(

Indeed ... VESA is the solution. It's support is not perfect but
works acceptably on most cards. VESA 2.0 is the probably most useful
version for the beginning. Just make sure to call INT 10 from REAL
MODE only ;-) LFB can be written from PM then.

VESA offers 640x480 LFB modes ... VGA only 640x480 with the great "planes" technology ... enjoy :-D
