For those still rocking (ha!) the ASRock 4CoreDual boards and experiencing the MAC address problem after POST, I can confirm that the fix works and that the above "wiki.nothing.sh/" link works as of the date of this reply. The megaupload link does not work. If the wiki link stops working, PM me and I will send you the MACtool folder. You need to copy the whole folder to your boot disk, not just the mac.exe tool. Necro!
