amd athlon64 3000+
i bought the second 6600gt card last week,its bios is newer than my old one,
so i tried using nvflash to flash the bios of my old card.
i made a copy of the new card bios in .bin format and try to flash it in the old card using nvflash in dos
i erase the old card's bios and now the card wouldnt work.
can anyone help me out on how to flash the new bios in the old card in sli?
the old card isnt working and i dnt have an agp+pci-e mobo.
can i do it with 2 pci-e cards in sli?

I think it would be recomended to use te boards separately for the flash (not in SLI mode).
Try using the command "nvflash -4 -5 -6 new_bios.rom" in MS-DOS mode. ("new_bios" must be max 8 chars).
Good luck with the flash !
