Just for the information of owners of this board; there are 10 beta F5 BIOS updates, from 'f' to q & there are 4 beta F6 BIOS updates from F6b to F6e. The current F5 BIOS update is F5o, which I think is corrupt at Gigabyte download webpage? This needs to be verified with technical support, as it would not work on my board

It was a matter of trial and error in my case to get one of those BIOS to work, as some of the updates did not work. Just for the information of -UD9 owners/users looking to update their boards
