just received a message from Gigabyte recommending l update to bios version: F14b
will sort this once lm back home in a few days.. l just hope l can use @bios and that sorting it out is simple, not had good experiences updating the bios in the past, l dont want to end up with an unbootable PC.. but lm hoping if something does go wrong l can restore the backup bios (myboard had dual uefi bios from what l could tell from the manual).
