Npci=0x2000/0x3000: Use it ì you're stuck at PCI Configuration begins. iBoot is the application that you have able to run Mac OS on. Any Linux or Windows operating system cannot beat Mac operating system. MAC OS best operating system of still available. Because MAC OS PC too much expensive than Intel processor-based PCs. Changing the value will help fixing the problem. Most of the people used Intel processors based PCs. PCIRootUID=0/1: Some PCs set the default UID in the DSDT as “ Name (UID, ) ” which can cause black screen when booting ( especially PCs use discrete GPU ). It's required to get some AMD card working. Use No for 1366x768 resolution use Yes for 1600x900 resolution or higher.ĪtiConfig=xxxxxx: Set the personality for your AMD card. IntelCapriFB=x: x ranged from 0 to 11, inject available ig-platform-id from Chameleon for HD 4000.ĮnableDualLink=Yes/No: Use to inject Dual Link information for Intel’s iGPU. IntelAzulFB=x: x ranged from 0 to 15, inject available ig-platform-id from Chameleon for HD4400/4600/5000/Iris.
InjectIntel-ig=x: x is the id of Intel’s iGPU, use to inject ig-platform-id for HD 4000/4400/4600/5000/Iris. GraphicsEnabler=Yes/No: If Yes, Chameleon will auto-detect the GPU and inject the needed information into OS X in order to load the right kexts if No, Chameleon will inject the GPU’s original information, use this when Yes isn’t working. Most Dell laptops need this.Ĭpus=1: Avoid lapic kernel panic which causes auto restart. x: Boot into safe mode, won’t load graphics kexts, can overcome the GPU related error on some PC.ĭart=0: Avoid conflict when vt-d is enabled in BIOS. v: Show verbose screen when booting or shutting down, useful for debugging errors. Remove this flag after you have installed all the additional kexts needed. f: Ignore all cache and force OS X to reload the kexts inside System/Library/Extensions and Extra/Extensions.
