More
and more people are now building systems without a discrete graphics
card or mixing on-board and discrete. As of version 2.2 of Chimera, I
added a few new boot keys in order to accommodate these alternate
graphics device configurations and port layouts.
IGPEnabler
Usage: IGPEnabler=Yes/No
Usage: IGPEnabler=Yes/No

IGPEnabler enables Intel HD Graphics regardless of GraphicsEnabler configuration. For example if you have a GeForce "Kepler" (6xx or 7xx) graphics card, and you want to enable QE/CI for it and the onboard controller, you would use GraphicsEnabler=No together with IGPEnabler=Yes. Thus having both graphics controllers fully supported.
IGPlatformID
Usage: IGPlatformID=[value]

IGPlatformID=[value] overrides the Chimera default snb-platform-id or ig-platform-id IORegistry key values for the Intel HD Graphics 2500, 3000, 4000, 4000 Mobile, 4600, 4600 Mobile and 5000 GPUs to allow for the use of an alternate port layout. The [value] must be 8 hexadecimal digits that correspond to a valid framebuffer platform-id recognized by the driver.
IGPDeviceID
Usage: IGPDeviceID=[value]

Version 3.0 of Chimera adds IGPDeviceID. Not all Intel HD graphics
device-ids are supported out-of-the-box. For these devices, we've
injected a device id that is close to or similar to achieve basic
default resolution. If you want to inject a different device id from the
ones we've used, you can use IGPDeviceID. Usage: IGPDeviceID=[value]

To view what settings you've booted using, collect your boot log by typing bdmesg in your Terminal window.
1. Open /Applications/Utilities/Terminal
2. Type bdmesg
3. Inspect output
Example:
Code:
------------ INTEL DEVICE INFO ----------------------------------------------------------- Class code: [0300] Intel HD Graphics 4000 [8086:0166] (rev 09) Subsystem: [1458:d000] :: PciRoot(0x0)/Pci(0x2,0x0) Using default ig-platform-id of 01660003 ---------------------------------------------
