GeForce 7, 8, 9 & 200 Series cards

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)

Mavke is the bomb! I've been visiting MVKtech for awhile now. You can find some really interesting modded gpu bios there if you hunt around. He has written so many bios flashing tools, he should get an award or something

I've used this process on several 7800 series cards. Lots of potential (as long as you don't fry the card or corrupt the bios)

Yep Mavke knows video card BIOS like the back of his hand

If you have Windows 2000, which has no built-in ability to create bootable floppies, you can use drdflash instead.

Just stick a floppy in the drive, and it'll unpack its image onto the disk. You then add whatever files you need to it.

Cool thx,
You can also use a USB stick to flash your BIOS, I don't know how it's done though.

To use a ThumbDrive images you will need to use this tool, made by HP, Drive Key Boot Utility. First download this and then follow the below instructions.
HP Drive Key Boot Utility v7.41.3790.0
Plug in your ThumbDrive/USB Memory Stick
Install and Open the HP Drive Key Boot Utility
Choose the Drive Letter of your ThumbDrive
Create New or Replace existing Configuration
Next you Change to Floppy Disk
Select Image from File, and Point to the Image
The Utility should ask you to Remove your USB Stick
Take it out, and Plug it back in and Check the Files
Leave the USB Stick in, Reboot into the BIOS
Goto the Boot Order and Select Removeable USB Drive
Select it as First Boot Device, Save and Reboot
After Bootup, it will Automatically Flash the BIOS

In my case it set it from stock to the KO overclocked card

what can I do?
(I have a usb romba? or a cd writer?)

killerfromsky · 01-28-07

You can flash it through CD, but you will need to make it bootable. I've done it before, however I never tried flashing through USB.

And yes, you can unlock pipelines if those can be unlocked, however you will need to know how to opereate with hexadecimal code, which I doubt you do (I dont either beside some noob voltage editing). Use Riva Tunder to unlock if possible.
