It was able to erase the BIOS without problems, but failed to write the new BIOS.
i knew that when i next rebooted the computer: it would be a brick. But before i rebooted i transferred the bios backup, the new bios, and Asus DOS-based flash utility to another computer. This Asus motherboard has a fail-safe bios recovery called This Asus motherboard has a fail-safe bios recovery called Crash Free BIOS, where you put in a floppy or USB stick containing a file called p5and it will restore the bios from that file. It doesn’t do it automatically (it would be ludicrous to have the floppy drive read on every boot).
The cable consists of a parallel connector wired to something you can plug into the pins that also has a 2.7V-3.6V input to power the chip while reflashing it.
I made a really bad attempt at using a chopped up parallel cable and the ends from a USB header port thing.
To run the built-in BIOS flashing tool, you have press WARNING: Never use the ASUS Windows based bios flash utility.
This didn't work out well so I found at the local electronics store a parallel connector with a ribbon cable on it.
I took it apart and re-soldered the ribbon to the correct pins.
It wiped it clean, loaded the new one, and then it couldn't verify.
At this point your only two options are quit or retry.
So I retry, now it won't even try to write the bios. The motherboard is supposed to have a built in bios recovery mode, but it seems that was wiped out as well by the Windows flash utility.
Having no other choice I rebooted the machine and hoped for the best. It was time to send it back to ASUS so they could reflash it.
