You are probably out of luck on this one...proprietary bios, setup and software is what is holding you back. The only other way is to re-write the bios (afaik)..but there plenty of caveats to doing this, and I'm sure you can understand what you are up against in changing the fundamental bootstrap loader. I can't remember where to get the software to re-write the bios...but if you want to take the chance, somebody here should have a link.
good luck...personaly, I wouldn't attempt it.
