HOWTO: nVidia BIOS Flashing

GeForce 7, 8, 9 & 200 Series cards
This works for 4xx cards also but you have to use nvflash 5.95 LINK...
First some cards have 256mb and 512mb make sure get the correct BIOS, you can cross flash cards like using a BFG BIOS on a eVGA it works some people do it As long as both cards are the same like 8800GTS & 8800GTS, but I prefer to use eVGA BIOS on a eVGA card ECT.

I've only ever had one bad flash when flashing a FX5900GS to a FX5950ULTRA but I had a backup and flashed it back.

1. Download the correct BIO's file you need here NVIDIA BIOS LINK

2. After it's downloaded Rename this file to 1.rom

3. Download this program nvFlash v5.38 nvFlash LINK

4. Unzip nvFlash v5.38 create a folder on your desktop paste all of it in the folder.

5. Install a floppy in my computer right click it format and reformat it for MSDOS then open it.

6. open the folder with the nvFlash,cwsdpmi and the new bios 1.rom copy and paste them to the floppy, now the floppy should look like this,



7. Restart the computer with the floppy in.

8. Making a backup once you get to MSDOS and see the {A:\\} prompt next to the prompt type, nvflash -b backup01.rom (This Backs up your stock BIOS, just in case you have to flash it back)
IT' ALWAYS A GOOD IDEA TO CHECK THE FLOPPY TO MAKE SURE THE BACKUP TOOK



9. Normal BIOS Flash, next to the {A:\\} prompt type, nvflash -5 -6 1.rom This should flash it if it doesn't you force flash it.

10. Force flashing, next to the {A:\\} prompt type, nvflash -4 -5 -6 1.rom
That's it remove the floppy and restart, DONE


Now if for any reason something went wrong you have the backup on the floppy so you just do step 9. again with nvflash -5 -6 backup.01R flashes it back to stock.

nvFlash v5.38 Commands...
"nvflash -b backup.rom" (Backup your BIOS)
"nvflash -5 -6 1.rom" (Normal BIOS Flash)
"nvflash -4 -5 -6 1.rom" (Forced BIOS Flash)



I've never done a USB Flash but for anyone that needs info on it this might help,

So all I have to do is use Nvflash -i2 -4 -5 -6 name.rom? I want to flash the second card so in this case I need to do it separately. Why do you need USB? (sorry I really appreciate if you can explain the process a bit).

Flashing a GTX 480 using a USB flash drive

Update GTX 670-680 uses Nvflash 5.117.0.1

nvflash -4 -5 -6 name.rom works fine

Process, using nvflash found on the internet
Using a USB flash drive you need HP USB storage format tool and win98boot found on the internet.
1st you use HP format and create a DOS startup on the USB drive then put win98boot files on it and let it format like so then hit start,


Once it's done you put the Nvflash and CWSDPMI files along with the BIOS.rom you want to flash on the USB and restart you computer and bootup on the USB, then type the commands.

EDIT: Here are a few commands,
nvflash --list (lists your cards position)

Card should be under 1 if it's SLI card 1, and card 2 or what ever the number is if anything else shows up you like your SLI controler you have to flash like this.
nvflash -i1 -4 -5 -6 name.rom that flashes card 1, If you have SLI you have to flash card nvflash -i2 -4 -5 -6 name.rom also with a seprate flash.

nvflash -b backup.rom (Backup your BIOS)
nvflash -5 -6 name.rom (Normal BIOS Flash)
nvflash -4 -5 -6 name.rom (Forced BIOS Flash)
