After you Flash the Modified Bios you can use the loaders Advanced Options to install the cretficate and Serial Key. If you use the Loader v1.7.9 click on Advanced Options ... Activation Setup and use Gigabyte Certificate and any Serial Key you want (Acer, Dell, or Whatever) then click on More Options and click on Install Certificate and serial under Bios Mod. Then reboot just to be safe and you should be done.
There is any way to install the registration/certification (automated) without use a loader? Making a DVD with 7 instalation plus some files?
