GeForce 7 & 8 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 it should look like this,
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 backup1.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 backup1.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 backup.rom" (Normal BIOS Flash)
"nvflash -4 -5 -6 backup.rom" (Forced BIOS Flash)
