N卡刷bios （NVIDIA GPU VBIOS Flashing ）

1. nvidia-nvflash 已经在系统中，路径: /root/utils/nvflash
2 . 暂时停止挖矿 .
5.查看 Nvidia 驱动版本.
dkms status | grep nvidia
你会看到:
nvidia, 390.25, 4.10.17, x86_64: installed
6 卸载驱动.
dkms remove -m nvidia -v 390.25 --all
7. 结束进程 Xorg.
pkill Xorg
验证:
ps -ef | grep Xorgorpgrep Xorg
8. 按顺序卸载模块:
rmmod -f nvidia_uvmrmmod -f nvidia_drmrmmod -f nvidia_modesetrmmod -f nvidia
验证:
lsmod | grep nvidia
9.查看显卡.
./nvflash_linux --list
10.查看VBIOS
./nvflash_linux -v
11. 备份 VBIOS.
./nvflash_linux -b 86.06.68.00.6B.rom
The information after the -b is the name of the file you are backing up. Make sure to give it a descriptive name. Also, the file has to end in the .rom extension.
If the version is different across multiple cards, use this command:
./nvflash_linux -i0 -b 86.06.68.00.6B.rom
The number after the -i is the card number identified in steps 9 and 10.
12. 刷bios.
If you want to flash all the cards with the same VBIOS version, use the following command:
./nvflash_linux 86.06.68.00.6B.rom
If you get an error message that there is a subsystem id mismatch, you can use the following command:
./nvflash_linux -6 86.06.68.00.6B.rom
Note: This could cause more problems than it is worth
If you want to flash a specific card in the rig, use the following command:
./nvflash_linux -i0 86.06.68.00.6B.rom
The number after the -i is the GPU id that was identified in steps 9 and 10.
If you get an error message that there is a subsystem id mismatch, you can use the following command:
./nvflash_linux -i0 -6 86.06.68.00.6B.rom
13: 安装之前卸载的驱动.
dkms install -m nvidia -v 390.25
14: 重启
sudo reboot
15: 验证是否成功:
nvidia-smi -q | grep -E 'VBIOS|GPU [0-9]'
