Check out my new video on Upgrading to UEFI BIOS for Gigabyte Motherboards http://youtu.be/D-FcRUp2A-E This is a supplemental guide to building a hackintosh but is also a general guide for updating the BIOS for future compatibility and system stability. For the most part, this should also work for most Gigabyte motherboards but it is important that you download the correct BIOS update for your model.
