 NVIDIA Video BIOS Update Utility. Suitable for most video cards that use PCB reference design and some brand-name video cards. The DOS version only works from "pure" DOS, in the absence of extended memory managers such as HIMEM/EMM386/QEMM.


This is the official program from Nvidia for flashing the BIOS of video cards. Works from under the DOS environment.
Create a bootable floppy disk with DOS or a CD-RW with a DOS image, write the program and the new BIOS in the same place.
After booting into the command line, type:
nvflash <BIOS file name>
And follow the instructions that appear.

For persuasiveness and so that there are no unnecessary questions, I type:
nvflash -4 -5 -6 <Bios file name>

What should I do if the video card does not boot after flashing?
1. Don't panic. The problem is easily solved.
2. There are two ways out: insert a second video card, for example, PCI and boot from it to flash a non-working video card with an old biosome pre-recorded on disk. Or work "blindly". Often the system boots up, and if you type in the blind after loading the operating system:
nvflash -4 -5 -6 <name of the old BIOS file>
and press "Enter" you will return everything to normal without any problems.

For flashing BIOSes, there are programs for Windows as well. They come with Leadtek video cards, for example. But working through them is more dangerous and, of course, more convenient.
