Bios Mods -The Best BIOS Update and Modification Source

Can somebody mod the bios of my ASUS K55VD? On another forum i've heard there are no hidden menus so unlocking is not the case i think. I would like to have CPU settings, turbo mode etc. Is this possible? I can flash older bios versions if needed.

-Bios Type: AMI

Seems like nobody did a reply.
Hello guys, I'm new here, anyway I also need this modded bios.
I tried to mod the bios by myself following instructions on some other forum using some AMI tool but I always get "BIOS size not valid" warning and can not proceed further with this tool because of that.
Currently my BIOS is K55VD.408 but I can flash any other if needed just as the guy above me said.
For the download link I put several BIOS versions just in case.
