------------ flashing nvidia bios ---------------------
1. Making an Nvidia BIOS flash boot disk
All video BIOS flash operations need to be performed in DOS, so we will need to make a DOS boot disk first.
You can create a boot disk from within Windows XP by inserting a floppy and opening 'my computer' then right clicking
on the 'A:\' drive and choosing 'format.' From the format window, check the 'create an MS-DOS startup disk' option and
click 'ok.' Now that you have a DOS boot disk, copy the BIOS file you downloaded and the NVFLASH.exe file onto the disk.
2. Making a backup of your Nvidia video card BIOS
Before you flash your video card with the new BIOS version you downloaded, you should always make a backup of the current
BIOS, in case you run into trouble later on. To do this boot your computer with the BIOS flash disk we just created.
At the 'A:\' prompt, type 'nvflash.exe -b backup.rom' and press ENTER. The FLASHROM utility will create a backup of your
video card's BIOS (backup.rom) on the BIOS flash disk. We can use this to restore your card's original BIOS if necessary.
3. Flashing the BIOS on your Nvidia card
Once you have made the backup file of the old BIOS, it's time to overwrite it with the new value we downloaded. Here's what
to do:
From the 'A:\' prompt, type 'nvflash <name of the new BIOS file including the file extension>' and press ENTER.
To override the vendor/device- or subsystem ID warnings, use the -p and -u flags (for nvflash 4.42 and older) or
the -5 and -6 flags (for nvflash 4.46 and newer).
NVFLASH will now overwrite your old BIOS information with the new values. If you see any error messages or odd results,
do not restart your system. Consult the troubleshooting section below for further instructions.
If everything seemed to work correctly, restart your system and watch the video card information as it flashes on screen
during the POST process (it will be the first thing on the screen after you power on). Make sure it is correct and that
your operating system loads correctly. You may need to install drivers if you have changed the BIOS to that of a different
type of video card.
4. How to recover from a bad BIOS flash
You made your backup right? Good. If you saw an error message during the video card BIOS flashing process, the worst thing
you can do is restart your system, so DO NOT RESTART the computer. If incorrect or corrupted information has been written
over your video card's BIOS, you will likely get garbled video, no picture at all, or even a dead card for your troubles.
Instead, reflash the card right away with the backup you made.
Assuming you called the backup 'backup.rom' type this from the 'A:\' prompt: 'nvflash backup.rom' for Nvidia video
cards using NVFLASH and press ENTER.
Your old BIOS information will be reprogrammed onto the card, and hopefully will put everything right. If you see no errors
during this process, restart and hunt for a different BIOS file to try.
If for some reason you restarted the system after an error, or you lost video for some other reason, you can still salvage
things, but it's going to take a little hardware.
You will need a PCI video card installed in your system before you can attempt the rescue.
Note that if you are using an Nvidia AGP card, trying to use an Nvidia PCI card to repair it may cause problems with NVFLASH.
It's better to use a different brand of PCI card for this operation.
Use an old PCI card to boot your system while your AGP card with the corrupted BIOS is still installed.
Your system should initialize the PCI card first. If this does not happen, remove the AGP card and turn the
computer on with only the PCI card, go to your BIOS Setup and change the "Init Display First" option to "PCI".
Now reinstall the AGP card. Your system should boot normally with the PCI card as primary display adapter.
You can now re-flash the corrupted BIOS or use another one.
