The newer round of bios' have to be flashed with @bios. (or efi)
The problem is, if you don't like it or it causes problems like it did for me you have to take steps to get rid of it. For some reason after a while I was unable to boot into Windows on the new bios so I could not use @bios to change it.
I had flashed the new F9 to the main bios on my UD5H, and I left F8 on my backup. So what I did was boot up with the backup bios and hit Ctrl + F10, and this "swapped" the main and backup bios. Then all I had to do was throw the bios switch back to the main bios, boot up, and hit Alt + F10 and this overwrote the "bad" F9 bios with a copy of the F8 bios. Now if the system needs a fresh copy of a known good bios the F9 will no longer be there.
Make sense? lol.
It's strange that the F9 worked well for a few days but suddenly it went south. Oh well, F8 works fine for me. Edited by mandrix - 3/30/14 at 4:04pm
