Disclaimer: Author bears full responsibility for contents of this article I have been trying to do some graphics programming with a VGA card, but I cannot find any documentation on changing the graphics palette at the level of the BIOS. It should be simple enough, but the usual information I have on BIOS interrupts was written before the advent of RGB palettes. I would much appreciate it if someone familiar with low-level programming could give me a reference. Thanks... Graham Denham
