How do you revert a M92p to the factory BIOS?

A while back my ASUS GT 640 stopped working after a BIOS-update. A year has passed, and I've seen several others with the same issues.

 

Still, there's no BIOS-updates that mention a fix, and I still can't get any of the three PCI-e cards I've tried to work.

 

So, I wanted to try flashing my BIOS back to the factory default one, as that worked just fine for 6-7 months.

 

However, where do I download these old BIOS packages? And is there any information on how to flash them manually? That is, unless I can download an ISO image.

All the downloaded BIOS updates should still be on your hard drive in separate directories named for the BIOS version. Running the Setup file should install that BIOS into flash.   It won't get you back to the original one, but oldest will get you to the next update.

Re: How do you revert a M92p to the factory BIOS?

I'm no longer running the factory Windows 7 that shipped with the computer, as I've bought an OEM version of Windows 8 since then.

 

I can't seem to find any trace of previous BIOS-update files on my computer, even though I've gone through half a dusin of them the past year and a half.

 

Is there really no way to download older BIOS-versions for the M92p?
