On the website https://rog.asus.com/motherboards/ro ...helpdesk_bios/ for my ASUS ROG Crosshair VIII Hero in the BIOS firmware section there are BIOS versions 4006, BIOS 4402 here is 4304, which is described in post No. 5 is not in the list at all. How to explain it?
I have the same problem with my Crosshair VIII Dark Hero and Bios 4402. I can not boot into the BIOS by hitting DEL or F2. I ended up booting into Windows Recovery mode and entering the BIOS from there. I disabled Fast Boot but it did not make any difference. I have not seen many other reports of this problem. I asked on Overclock.net and everyone who responded said they were not having this problem.
