If your BIOS works for you, you should consider keeping it. 

Porting coreboot to a new mainboard is a significant effort and you will
have to make sure you have ways to recover from failure (i.e. get your
external flash writer and/or soldering iron ready)

However, in some cases you can get to sub second firmware boot times
with coreboot. And it is open source, so you can add or remove whatever
feature you require or not.

The Wiki is generally a great source of information.

So is the Super I/O
