1.) use Windows get geforce bios ROM
2.)download NVCAP generator and use ROM and get NVCAP
3.)install video drivers (NVinject, Natit, NVkush) (MUST DO IT PROPERLY)
4.)download plist editor
5.) open up info.plist from the video drivers (in the extensions folder)
6.)Add NVCAP from your generator.
7.)then restart with -F on darwin..

and if it doesnt work, just change the NVCAP to different values, until you get one that works... or try changing video drivers with different NVCAPs too.
