Thank you, let me clarify why I (thought) needed to get this to work again. When I rolled back to F6 the problem was that the LAN card stopped working, but apparently it wasn't the BIOS update itself, but that I have had the computer unplugged for a while.
I read around on the internet and noticed that some people had problems with their onboard LAN after unplugging the computer. So when I unplugged and plugged in the computer again, the LAN started working again.
Not sure of the reason why I installed the F7A in the first place, but it's working anyhow.
And I'm also quite curious of the "A" in F7A BIOS.
Reason behind the two threads is that I thought the problems weren't connected, and therefor would be easier to keep the threads separated.
Anyhow, the problem is solved, and it wasn't a BIOS problem. Now the only odd problem I have is the slow Windows and Ubuntu loading times, which seems to decrease A LOT when only using two sticks of RAM, although I didn't have the problem before. I could try flashing back to F6 again.
