This would be a start. Although adding a video mode is not just a matter of giving h and v resolution. You must provide some sort of parameter string and I found no documentation for that. > I hoped that the other files in this "vbios*.zip" file are the necessary > modifications for the implementation of a 1400x1050 video mode. As far as I figured out they are "plug-ins" for additional hardware (TV-out etc.) and configuration files for use with BMP. Problem is, not all configuration parameters are documented.

Anyway, I want to try the bios > replacement. If you really want to try: Yes, you can load the new BIOS at 0xC0000. But you have to make this area writable first. Documentation for that can be found in the 855GM datasheet from Intel. And probably you'll have to initialize the new BIOS by calling 0xC0003 in real mode. This call crashed for me so I had to patch some bytes of the BIOS image. You see: It's not really easy and I think the bytes to patch are different in every version.
