Glad it worked out asustech.
They do tend to take some time on Bios updates to the site, I can understand why as I've had problems with Bios updates in the past. Mine was originally an overclocking problem that was never resolved and of course they said as long as the default settings work, then that was all they are concerned with. I also had a Lan problem with an earlier Bios for this MB but didn't find out until the router had been switched off and back on. It suddenly clicked some time later that it could be the BIOS update and it was. They did sort it out though.
So if you do come across any problems later, then remember it could possibly be a BIOS update, especially if it's not yet released like FHm, the lower case last letter denotes that it is still being tested I think. I'm sure someone will put me right on that.
Anyway, fingers crossed it's problem free.
