OK so here's the story. Im going to upgrade my amd fm2+ system to and intel lga 1151 system. I'm on a tight budget so i was going to get the pentium g4560. The b150 motherboards are cheaper than b250 and I know the pentium wont work with a b150 mb w/out a bios update. So I want to know if i could download a kabylake bios update and update the bios through a usb drive.
