Please read other threads on how to backup your original BIOS and how to flash BIOS'es. I did a lot of reading/research before I attempted this procedure. This is my very first time I actually did this kind of thing to my video card. In other words, I'm a n00b when it comes to this.

I found the Jaton Corp. FX5700NU BIOS in the following website:

http://www.station-drivers.com/page/vgabios.htm

Look under NVIDIA Geforce 5700 4.36.20.35.15 Jaton

Note that this is a zip file of an executable. The executable actually makes a boot disk for you; so you need an empty floppy disk. I did not use the boot disk, however. All I did was just copy the file p191-0n.rom and saved it to my own boot disk. I mentioned this earlier but I will say it again anyway: make a backup copy of your original BIOS first, then try to flash the Jaton BIOS (please don't take this advise as an insult, I just don't want you to damage your video if something goes wrong with the flashing procedure. I've read in other threads and in other forums where others did not backup their BIOS and the BIOS procedure went wrong!!!). I used nvflash ver. 4.42 using the followng parameters in DOS mode:

nvflash -b backup.rom - to back up the original BIOS

nvflash -p -u -f p191-0n.rom - to flash my card with the Jaton BIOS

I hope this helps....
