Intro:
With today's expensive graphic cards and equally graphics demanding games, everyone is looking for a cheap alternative to play their favorite games on high settings with AA and AF!

In late 2004, eVGA released a Limited Edition of a 6800 Non-Ultra which had gDDR3 memory and 16 pipelines and 6 vertex shaders with the PCB and core of a ULTRA 6800, basically the 6800 Ultra with a bios of a 6800 non-ultra. Soon after everyone learned this, the community of hardware enthusiatics at BleedingEdge.com (or specifically Thugsrook) released his custom modded bios' to flash the eVGA LE 6800 to 6800 GT or Ultra, and later Aonic released a boot disk with the modded bios' and a fancy menu to make the whole procedure easy.

Hacking Instructions:
1. Make sure you have a eVGA Limited Edition 6800 ( http://www.evga.com/products/pdf/N347.pdf )
2. Download one of the following bios flash disk kits:
-(rev 4.0) CD-Image for eVGA 6800 LE Modded Bios Kit
-(rev 4.0) Self Installing Floppy Image for eVGA 6800 LE Modded Bios Kit

3. Burn or use the self-installing exe to make a floppy and boot from the cd or floppy
4. Use the menu's to flash to the bios of your choice
5. Boot up your OS and install the drivers again
6. Enjoy your games :D
