Got it sorted, almost.
Hammer was for removing the BIOS chip.
Since my game box's BIOS was corrupt, I had to find a way to reprogram it, so I decided to do a hot-swap with a BIOS chip from one of my other machines. This involves taking out the bad chip, boot up the good machine and then pop out its BIOS chip and replace it with the bad chip and then reprogram the bad chip with the correct BIOS. Yes, this is all while the machine is turned on. Potentially very stupid, blah blah blah

.
But since the two motherboards are different and use different versions of BIOS, awdflash didn't want to force the update, no matter how many different ways I tried to convince it.
Headaches and stress at 2am!. If I didn't get this to work, I'd have to send away for a new chip.
So I had to track down copy of aflash that would force it, which I
eventually found.
Anyway, bad chip is now good and I've installed the new cpu. By 4am there's just a few problems with windows not being too happy with the hardware being changed, but that's another nights work.
