Note:
The latest BIOS Update 1603 was release way back in 2014/09/19. So if you buy this board now, there is a possibility of you receiving a new shipment of ASUS MAXIMUS VI HERO that comes with either 1504 or 1603 BIOS pre-installed.
" If this is the case, then you don't have to do any of the methods I've mention above. Just buy, install the processor on the motherboard and you will be good to go. So you better talk to your seller and find out about this."
I purchased it on 12/1/14 from Newegg so it sounds like I should be in good shape for the 1603 BIOS and excellent shape for the 1504 BIOS. Thank you very much for your help.
