In addition you will
void your warranty
. Please do
NOT
email your manufacturer if this goes wrong!
For that reason, I would advise
everyone
to make a backup of their original BIOS file before they flash their
BIOS. You can use a DOS program called SaveBIOS to do this - just run the program and it will create a
VIDBIOS.BIN file. Put this file somewhere safe, and if you ever need to revert back to the old version just use
NVFlash with your backup file.
You can download SaveBIOS here:

If you were silly and didn't take a backup, try the following page:

See the 'Where can I get and how do I use NVFlash?' question for information on using the NVFlash program
that actually flashes the Video BIOS.

Q. Where can I get and how do I use NVFlash?
NVFlash does not work under Windows 2000. If you want to flash your Video BIOS under Windows 2000,
you will need to make a bootdisc on a computer running Windows 9x and boot from that disc to run NVFlash.
If you are using NTFS you will have to put all the relevant files that you need to access onto the boot disc
before you start as you will be unable to access your hard drive while you are using the boot disc.
If you want to use NVFlash under Windows ME, make sure you install the Real DOS-Mode Patch for
Windows Millennium first - available here:

Be warned that flashing your Video BIOS could quite possibly permanently damage your card, and it is
unlikely that any company would be willing to replace the card for free. Having said that, so long as you follow
these instructions you should not have any problems. This is NOT for beginners.
You can download the NVIDIA Flash program at the following website:
http://www.x-bios.3dgames.ru/
or here:

You will also need a copy of DOS4GW - download it here:

1. Extract both files to an empty directory, along with the Flash BIOS file that you are going to use (see
'Where can I get the latest NVIDIA Flash BIOS and which should I use?' question).
2. Reboot your PC and when it says 'Starting Windows 9x/ME...' press F8. Select 'Safe Mode Command
Prompt'.
3. Switch to the directory where you extracted the files and type: NVFLASH -f
FILENAME
where
FILENAME
is the name of the Flash BIOS file you downloaded.
4. Now wait. The screen may go black, but watch the keyboard lights - they will make a pretty pattern to
assure you that the system is still working ;)
