I'm looking at a new custom build with the Asrock Z97E-ITX/ac mobo and the Intel i7-4790K, and that processor is not supported without a bios update. In the past I've used Asus BIOS flashback with a physical button that lets you flash the BIOS without posting or turning the PC on, will I be able to flash the BIOS on this CPU installed, or will I need to find another CPU to do the BIOS flash?
