Run nvflash -r to strip register protections, followed by nvflash -w to disable software write protection. If it still fails, check the physics card for a physical jumper labeled WP or BIOS_EN and move its position.

If a Windows-based flash failed, or if an experimental VBIOS caused a black screen, booting blindly into DOS with a secondary PCI graphics card allowed users to force-flash the original working VBIOS back onto the primary AGP/PCIe card.

The situation became more complex with the release of NVIDIA's Maxwell architecture , which includes the GeForce 900 series and GTX 750/750 Ti.
