Fresh Build, Can't Bios

[Psymonx]

I just built my new PC. It is as follows

Asus Rampage Formula
E8400
MSI 8800 GTS
4gig Corsair dominator 1066
WD Raptor
Tuniq 120
PcP&C 750

It runs fine, and befor any OC I got a FutureMark06 Score of 12.5k.
The ONLY hitch is, I cannot get into my Bios. My keyboard doesn't respond
Anyone got any ideas?

If you are using a USB keyboard, try it with a PS2.
Some BIOS version don't default to allow USB keyboard support.
