Bios Mods -The Best BIOS Update and Modification Source

okay so since i have been researching on how to mod my bios, i have gotten to a point where i have my bios file and am able to view it using mmtool. My problem is i dont know what to look for to add a bclk option to my bios. i understand that i have to extract a file using mmtool and modify that file. than inject it back in. the file i extract literally is only numbers, so how would i find out where to tweak this option.

thanks in advance for any help

Better to use PMT259 for any modify or UEFITool !

Find on MDL forum them !
Regards

okay now i have found the file i need to modify i have extracted the section it is in but am unsure how to modify it. could you direct me to somewhere on how to start editing the hex values of the sections i extract. thanks
