That won't help him.
He still has to short pins 6 and 7..
Then he has to be able to somehow make it far enough to manually download and flash the primary bios. He must have been overclocked far (maybe with PLL overvoltage enabled) for it to reboot during an auto recovery...

This is why it's essential to alt f12 to copy the main to the backup bios before you do any overclocking. You don't want to get stuck in a boot loop at the same time the bios gets "falsely" corrupted during a failed OC (which on those old bios revisions, constantly tries to flash the backup back to the main).
