Going on a hunch and not wanting to some day spend a week or so waiting to get my NF7-S back on the air, nor wishing to pay ~$30 for a bios savior, I tried an experiment last night.
I had a recent vintage motherboard laying around, collecting dust and upon looking up its bios flash prom 49FL040-33, I discovered it was the same capacity (4Mb), pin and level compatible with the PMC PM79FL004-33 on my NF7-S.
Before embarking upon this venture, you need to have FlashMenu installed and functional. That's what I always use for updating my bios, so I was all set. I took the flash prom out of the ASUS motherboard, set my NF7-S bios for System BIOS Cacheable and rebooted. I then did a Shutdown/Stanby and once the PC settled down, I pulled out the flash prom on the NF7-S. I then seated the flash prom from my ASUS board in its place and woke it up from Standby, holding my breath. Sure enough, it woke up fine and after it settled down into the desktop, I launched Flashmenu and programmed it from the file I already had in the FlashMenu directory. When it finished verifying, I rebooted and it worked perfectly. I rebooted several times, changing this parameter and that, just to make sure it was repeatable. Once satisfied, I shut down and swapped the Abit flash prom back in. Now, I have a backup flash prom.
Unfortunately, if I ever want to put the ASUS board back into service, I'll have to reprogram its flash prom back to the appropriate bios for that particular model.
For now, it's nice to be able to play with odd overclocks and not have to be concerned about possibly screwing up the flash.
Look around, you may have a similar situation.
