I'm needing to update to the latest BIOS on my ASUS Maximus II Formula. Right now it's 0901 and the latest BIOS REV. is 2302, 5 or 6 revisions latter. My question is, can I update it to the latest BIOS rev. in one step, or do I need to go in steps by step and do each update in order? I would rather only flash the BIOS one time, even thought the board has dual BIOS.
