i have flashed my SAPPHIRE HD4670 1GB DDR Ram and i have changed the max overclock signatur file and now my card would not be recognized under windows.

ATI HD4670 CODE 43 Error

I think i destroyed the signature key and now the card wont be recognised from the ati catalyst driver.

Has anyone a original bios file for this card ??

If not can i throw the card away?? Or what ??
