Hi I have P67A-UD3-B3 mother board with the F9 bios right now and I would like to update to the latest UEFI bios.  I guess I need help in getting started in this update process.   do I need to make a usb stick bootable ?  if so how? Do I use Qflash for this update?    when I download the uefi bios from gigabyte there is only 2 files and I have read there is supposed to be 3 files.   
thanks for your help.
