this motherboard is locked down. flashrom does not support unlocking it yet. (it will hopefully be my job to change this, if i am accepted for gsoc: http://flashrom.org/pipermail/flashrom/2011-March/006016.html).
flashrom will (probably) bail out when you try to write to the first region, or read from the third, but i would not try it if i would be you.
