Needless to say I am pretty confused since the OP flashed this BIOS and got extra menus. Could someone please explain this? I'd like to follow donovan6000's guide and do my own mod myself to gain experience, and would like to use the already modified file as a check vs my attempt to make sure I don't brick the laptop.

Lol I guess aricart is so good that he can mod bios without even touching them

Turns out he didn't mod the Windows 8 bios at all. I guess he accidentally uploaded to original one. However he did mod the Winodws 7 rom, which is located in the os2012381b_610.exe executable stored in the skbqv610.exe executable. You'll find that the changs he made were in the SetupUtility module, fe3542fe-c1d3-4ef8-7c65-xxxxxx.

No two bios versions hide the tabs in the exact same way. The tutorial on my blog mentions this, and it's not meant to be a sure fire way of unlocking the tabs on every bios. The bios aricart modded contained a blacklist that prevented certain modules from being initialized. You'll see what I'm talking about when you compare the differences

Cool thanks for the tip. It'll probably be a few says until I try this. Just an FYI the laptop I'm doing this to is a win8 L875D. Hopefully the win7 version is similar enough to follow.
