Adding features to BIOS?

[Sabertooth Python]

I've got an OEM board that really makes me cry, but can't replace it for now. I've figured out unlocking all the hidden features, and was rather quite disappointed when I learned that voltage control isn't included in there.

It's an H57M01 motherboard with the P01-B2 BIOS. I'm rather new to this area, but I'm not entirely green to programming (however, high level, not low)

What information could you guys give me about adding voltage control to an existing BIOS? (Please no "buy a better motherboard" as that's just not an option as a college student--I'd also need a new CPU if I did that, and I won't cheap out)
