Re: BIOS upgrade
Most manufactuers lock the BIOS to prevent you from oc'ing, well, ones like HP, gateway, dell, etc. Acer, too, evidently. You would have to flash your BIOS using a disc from the manufacturer. Doing it manually could damage your mobo. I don't want to take responsibility, so I would suggest you contact Acer and see what they have to say.
Macbook Pro and Logitech z5500s. All you really need.
