Using nvflash

So far nvflash v4.46 has been most reliable for me with GeForce 3 and 4 era cards.

For sanity in DOS name the ROM(s) using 8 characters or fewer.

Always reboot fully into actual DOS mode before using:

• Reboot
• Mash F8
• Command prompt only

Backing up a ROM

Always back up the existing ROM first!

nvflash -b backup.rom

Flashing a new ROM

Try the basic command first:

nvflash -f new.rom

If you get ERROR: PCI subsystem ID mismatch, use -6 to bypass the error:

nvflash -6 -f new.rom

That’s it really, if something goes wrong just re-flash the card with the backup you made first.
