My understanding is that you can usually flash the BIOS from the BMC even if the BIOS is fucked, though it's a paid feature upgrade (though I think someone might have cracked the algorithm on older boards).
At least, it has been the case on several boards of mine, including an X10SDV which bricked itself, as far as I can tell, just from bad luck somehow.
