I have verified that OS X Lion breaks support for Nvidia's 8800 GTS 612 (G92). The startup freezes on the grey screen but the OS continues to boot, you just cannot see it. One fix recommends flashing the GPU's ROM. I have a ROM created by someone and they say it fixes the issue. However, I am having trouble finding the program. It's called Zeus and I need to find version 1.3. I have 2.5 and it does not work. Does someone have a copy of Zeus 1.3 they can email me?
