I see in the source file, nvidia.c that it list the nVidia GeForce 200 as a supported card. MIne is by EVGA with 512MB DDR3.
If I boot using GraphicsEnabler=yes I get a black screen. If I boot with GraphicsEnabler=No I get a boot inot OSX Snow Leopard with a normal screen but no acceleration.
So it looks like the card is not supported even though its in the list?
I have read around that I could run nvflash.exe and get a Boot.rom then use Nvcap Maker and Osx86Tools to get an EFI string. You would think though that Chameleon would already have this script in place?
