- The problem is not in writing the driver but in setting the dot clock
- values on the card. Diamond uses a custom clock synthetizer. What
- this means is that other than the 640x480 you can't set the clock
- values for higher resolution, unless you sign a non-disclosure
- agreement with Diamond. As for being a VESA driver under
- Unix we write directly to the vga registers we don't use the BIOS.
