No. Unless you have a second flash chip with a backup of your BIOS or you can reburn your flash chip in another board.
Ah, I wouldn't want to do this then, as I use my machine regularly. It does have a Dual BIOS, so not sure if it means I can recover if something goes wrong. If I wasn't using it, then I'd be happy to do it until we got something supported on it.
