Do you guys think I need a different Kernel for my Mach Kernel? Sometimes command -legacy busratio=17 UsekernelCache=No npci=0x3000 PCIRootUID=0 Graphics Enabler=Yes does not work! I'm using Mach Kernel v4 with a Amd Phenom II x4 965 3.4ghz and gigabyte gtx 570 card with 4 gigs of ddr3 ram. Motherboard is Asus M4A79XTD EVO. That or maybe I need a different command. My Hackintosh Lion acts very strange. I have to shut my computer down like 3 times before the command finally works, why the heck would that be?
