Asus DSBF-DE

Hey guys I was wondering if anyone could help me with getting the bios on this board unlocked. I know its old tech and kinda odd being a duel socket 771 server board but it would be nice to be able to do some light OCing.

Specs
e5450 x2
12gb-ddr2 FB-dimm
gtx 750ti
kingston 60gb ssd



Any help would be much appreciated
