8800GT Bios Flashing Guides

[MajorBuzzon]

I can't seem to find a good guide or how-to for bios flashing my 8800GT.Haveing not flashed in years,and never with a flash drive.Got the flash drive formated to MS-DOS startup disk,have nvflash v5.57 loaded and new bios made in NiBitOR v3.7 but every time it go's to load new bios get I\O error.Tryed bios i made with NiBitor and downloaded bios and get same error,think i may be missing a step in process.Does any one know of a good online guide for flashing 8800GT bios,i use XP.

Why would you want to flash? You'd lose your warranty. Flashing to a new bios does not improve performance in any way. Correct me if I'm wrong here.

Well i want to flash so i can set my overclocks in bios,so i don't have to use RivaTuner or like program.I have had my 8800GT's long enough to know there best clocks,and they are XFX cards,they are fine with almost anything LOL,and double life time warranty too.Did this with my last three cards before 8800GT's(6600gt,6800xt,7900gt) but with 8800GT i get error ,my be because of vista having problems with nvflash

Maybe I'm thinking of something entirely different, but I thought NVFlash was a boot program, not an OS-program.
