This MAY work, then again it may not... I know on my old MSI Socket754 motherboard I had, had a neat little trick. I believe that if you turned off the system, held down a certain key combination, turned on the system, if there were any low-level BIOS left in the system, it would scan the floppy drive and/or CD drive for a BIOS image, and automatically apply it. You'd hear the PC Speaker beep after it was done. This might not apply to your board, but if you perhaps poke around the manufacturer's forums, you might find something like that.
I thought the key combination was F4+Delete, but it's been three years since I had to do that last and I couldn't tell you if it'd work or not. Besides, mine was an MSI, might be different for a DFI board.
