Help understanding bios mods

[codeman848]

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
