Just to clarify something, F14 revision made my network card (onboard) ... "invisible". Not detected by BIOS or windows anymore. Revert to good ol` F13 everything come back... Exchanged a couple of `mails with Gigabyte tech support they asked me to use F13 as per instructions F14 is still beta. Their response below:
"Answer : Hi,
There are two ways to check the problem.
One is to update bios to the latest beta F14m, however, it may not work as solution and fail as F14k.
The F14k and F14m are beta bioses, not a formal release, so that there may be some unknown issue to be checked.
The other way is return to F13 after testing F14m fail or not test it at all.
It is suggested to keep F13 until F14 formally released."
