Bios Mods -The Best BIOS Update and Modification Source

Hello, I'm new here and I'd like to know how can I unlock my BIOS:

> Clevo P370EM || SAGER NP9370
> American Megatrends Inc.
> Version: 4.6.5
> Aptio Setup Utility 2.15.1226
> Release Date: 11/13/2012
> System: Windows 8 Enterprise x64

I activated UEFI and Secure Boot. Know I want to unlock and active Trusted Platform Module (TPM). Please help this newbie...

Thanks!

Hi,

Anyone that would be able to get a modded bios for me with the hidden options unlocked + the options to overclock?

Specifications:
i7 3740QM
16GB DDR3
AMD HD 7970M x2 (only one of the mxm gpu is working for the moment)
