I have to disagree with that; installed untouched HP OEM Win 7 x86 Professional and it did not activate.
AWDFlash is a DOS Flash Utility. You can NOT Flash it from within Windows. You need to Make a BOOTABLE USB as shown in the Link in my Post and ReBoot and Flash from DOS. If you Really have this MB: EVGA X58 SLI LE you can go look at the EVGA BIOS Download Page and see that this is the Last Bios (released Before v6.4) for your MB. If you don't know how to determine if this BIOS is for your MB, DON'T FLASH IT , Use The Windows 7 Loader by Daz or BUY a Legitimate Copy !
