100% certified mainboard for AMD64

[l l]

Hi,

I am using amd 64 x2 4800+ (60nm), my mainboard is from biostar.
http://www.biostar.com.tw/app/en-us/index.php

My guess: This mainboard seems doens't work with coreboot.

So i would like to have mainboard which is 100% safe works with my amd64 system.
I don't care about price, i want buy it now.

Any information that would be very appreciated!

TIA
