Bad BIOS flash

I have an unidentified brand nVidia GF6600 card that I decided to flash BIOS, in attempt to fix an issue with crashing as soon as VGA drivers are installed.

I saved original BIOS using SaveBios. Flashed card with a newer nVidia file,using NVFlash, but card didn't boot. OK, no big. The problem is, when I re-flash the card with original BIOS, it still won't boot!! I've even tried flashing the card with a few other BIOS's (from MVKTECH), but none of them boot either.

I've flashed BIOS on tons of hardware, of all sorts. This is the first I've seen that won't work after reloading the original saved code. BTW, if I open the saved BIOS in NiBiTor, it looks funny... but I'm not very familiar with BIOS editors or editing.

Any ideas?
 
If it was not working as soon as you installed drivers... I hate to say it, but no great loss, right? Try finding another BIOS to test, sure, as there's a chance the original saved file is bad, but if you can't get it to work pretty quick I'd stop wasting time on it.
 
LOL, one thing I'm known for is wasting "too much time" on stuff that "isn't worth it"... :p

But it's fun, I like the challenge. Wish I could at least identify the make of the board.

scan the card and post a pic or upload the original bios.

I'm having an ignorant moment...
--scan the card and post a pic? huh?

--I have the original bios saved as .bin, but I'd need an external upload site that could then be linked in post, right?
 
stick the card into a scanner or take apicture of it so we can identify it... or post the bios so we can see who made it and get you a copy that isn't corrupted or whatever. rename the bios.bin file as .jpg or .gif and upload it anywhere.
 
OK, here's the pics: (good luck, this thing is as generic as they come!)

I renamed the BIOS, but photobucket was smart enough to realize that it wasn't a proper JPG and refused to upload it. Still looking for another upload option.

Here's are screen shots of NiBiTor with the saved original bios.

Obviously, the 2D clocks look wrong... as do the BootUp clocks.
Voltages - Vid Mode yields an error, but I can't read German.
Voltages - Exact Mode was clear in all entries.
Timings was clear in all entries.

Is there any BIOS translator that could be used to read the BIN or ROM files? (Something that works like opening other codes in notepad?...)
