Poopdepoop, use my Natit. Your ROM file is *exactly* the same as the one from zvon and everyone else, that's included with Cindori's lovely tool.
Also, please let me know if you get it successfully flashed.
Cindori, I don't have my original ROM file - hindsight is 20/20, but I figured if several people have the exact same card as me and it works for them, it should work for me too. I didn't know about those different revisions, and I don't have access to a Windows machine - so I couldn't save the ROM before I started, and I can't test the card on Windows now. However, it's working perfectly with Natit, which only uses the first half of the ROM (which is what I understand is the BIOS, used by Windows), which leads me to believe that it would also work fine with Windows.
I wonder if there might be something else going on, though, because Poopdepoop bought the same card from the same place (newegg.com) a few days after I did, and zvon et al. bought the same card a few days before I did. And they all have exactly the same ROM. Seems weird (but possible, I admit!) that I would have a different version in between them.
Poopdepoop, could you please do me a favor and check what the stickers on your card say? There's one on the side of the fan assembly that on mine says "P/N: FC00125-R0" and then "2B932C1" on the next line. These are the only numbers that other people haven't reported. Mine matches everyone else's in every other way.
Thanks all! Poop, I hope my Natit helps you!
