[revised by svl7, 01/22/12] Here are some unlocked versions of the M18x BIOS, this means all the hidden BIOS menus are now available. This allows you to further tweak and overclock your machine, but some settings are very advanced and not meant to be touched by the average user, so use it with care and common sense. Unfortunately quite some of the links which were previously posted here are now invalid due to what happened with megaupload. I will try to recollect all the files and get fresh link
