Bios Mods -The Best BIOS Update and Modification Source

I have a mcp61p-narra-00 mobo, codenamed Narra. It's out of a HP a600n, here. Now this mobo supports raid, chipset and all. The problem is HP gives only the most basic features in the bios. I was wondering if you guys could unlock the RAID options in the bios for me? Just let me know what you would need from be. And by the way, I have been up and down google looking for modded bios.

Thanks in advance,
