There is a problem with this. Although the original (IBM) VGA hardware was totally documented right down to individual register bits, the VGA BIOS calls are fully documented, and the VESA video BIOS extension (and other VESA stuff) are fully documented there is, AFAIK, no free implementation of either the VGA hardware or the video BIOS.
How to write a BIOS is well-enough documented, and I've done it before (as has Andy). Also, Patrick helped identify most of what we need to know about VGA in order to implement it correctly. The text mode will come first, and that's much more straightforward than the graphics mode. -- Timothy Normand Miller http://www.cse.ohio-state.edu/~millerti Favorite book: The Design of Everyday Things, Donald A.
