Flashing OEM board to Retail or?

[Detailed]

Hey guys, is there any way I can flash a retail bios to an OEM Board? The OEM Board is an Asus F2a55-m/m11bb/dp_m. I've attempted to flash the original Asus F2A55-M bios on it with no luck as it ends up with a verification error using Asus EZ flash (Not the F2A55-M LK and all those other ones, just the plain F2A55-M). The main differences I've spotted between the OEM and Retail is that the OEM has a removed PCI Slot (You can see the holes for where it should be placed) and the GPU Boost switch has been removed. This is the PC with the OEM board http://www.microcenter.com/product/41636...p_Computer (You can click one of the pictures to see a high quality picture of the insides) and this is the retail. http://content.hwigroup.net/images/produ...162542.jpg
Any help is appreciated, thanks.
