NVIDIA NVFlash is used to flash the graphics card BIOS on Turing, Pascal and all older NVIDIA cards.
NVFlash supports BIOS flashing on NVIDIA Graphics cards:
GeForce RTX 2080 Ti, RTX 2080, RTX 2070, RTX 2060, GTX 1660, GTX 1650
GeForce GTX 1080 Ti, GTX 1080, GTX 1070, GTX 1060, GTX 1050
and many more, including BIOS flashing on older NVIDIA GPUs.
Before flashing, backup the current graphics card BIOS with: nvflash --save backup.rom
To update the graphics card BIOS, use: nvflash bios.rom
If you want to flash a RTX Founders Edition board with a non-FE BIOS, use this modded version of NVFlash.
