That doesn't work when you corrupt the bios with a bad flash. If your board was super cheap it wont have a socket-ed bios chip.
That board, does in fact, have a socketed BIOS chip. It's along the front edge of the board, in front of the *cough cough* ISA slots. I'm curious though, why are you flashing the BIOS on a Socket 7 motherboard?
You might be able to restore the original BIOS if you saved it as is often the case before installing a new BIOS.
