Bios Mods -The Best BIOS Update and Modification Source

Hey guys,

Model: HP Spectre XT 15-4000EG

Screenshot of BIOS:

since I'm currently planning to make a hackintosh out of my notebook, I desperately need to set the Shared Video RAM for my Intel HD 4000, one of the billion settings my BIOS is lacking -.-'

Therefore I would like to ask you to unlock this BIOS for me:

Thanks a lot for your effort and help, love this forum and come back here every few weeks for your great work!

Sincerely,
LilaQ

So, pretty please, help me out on this!

Thanks in advance,
