Acer AM3450-UR30P Bios Unlocking??

Hello, I was wondering if someone could help me with unlocking the bios in my computer? It's an Acer AM3450-UR30P running an AMI bios (AMI P01-A4 4/20/2012). I have tried flashing it multiple different times , and it tells me that the bios is Write-Protected... I was just wondering if there is any way around this? because at this point I am clueless and it wont allow me to use either of my graphics cards.
