Here are the cards that work: Leadtek's 5900 series including the slower LX model, Gainward's 5900 series, Elsa 5900 series, Insight 5900 XQ series and Rex Technology 5900 series.
BIOSs used: Leadtek A380 5950U and Gainward's 1800Ultra "Golden Sample" *Note: NO YOUR CARD DOES NOT HAVE TO BE FROM Leadtek or Gainward to use their BIOSs*
1.) Make a MS-DOS bootdisk. Copy the contents of the zipped bios onto that bootdisk.
2.) Reboot the computer and boot off of the above mentioned disk.
3.) Type "A:\nvflash -b original.rom" but w/o the quotes. This will back up your original BIOS
4.) Type "A:\nvflash -f n5950u.rom -u -p" but w/o the quotes. This will flash your card's BIOS and make it work like a 5950.
5.) Restart your computer and voila!
The reason this works and why you can have a 128 MB 5950 is because the memory buffer is not stored in the BIOS in nVidia cards like it is in ATIs. Do not be suprised to see either a Leadtek or Gainward logo whenever you start up your computer even if your card is not from them. IT IS OKAY! Watch card tempuratures though because it can bring it fairly close to 50 degrees C. Hope you found this helpful!
