I was talking about the BIOS files from the official ASUS website (the BIOS section, not BIOS Update (Windows)). For example, if you extract the latest RC71LAS342.zip, you’ll get an RC71LAS.342 file with an 800h header that needs to be removed.
Also, for the settings unlock, I suggest starting a seperate new thread with a clear title like “BIOS hidden settings unlock.” Idk, It appears to me that users might think it’s ONLY a password request, which could be why you’re not getting help on the other issue.
