Hi, I'm using Chromebook Pixel (specs: i5-3427U、HD4000、4G DDR3 1600) with onboard graphic HD 4000, i use clover r3270 to fresh install 10.11.

with setting ig-platform-id 0x01660002 and InjectIntel, i can successful boot with QE/CI:

but screen usually glitch, especially mouse move or click, like this:

i try other ig-platform-id 01660000 1 3 4 8 9 a b with InjectIntel, but all of them give me same result, can't boot. if i uncheck InjectIntel, can boot but no QE/CI.

i use verbose mode, when ig-platform-id 01660002, i can see PPGTT is enabled, with other ig-platform-id values, can't see that.

check and uncheck InjectEDID, nothing different.

i try yosemite, same result.

Please help me, thanks a lot !

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

Mobo: manufacturer/model + bootloader(Clover/Chameleon/Chimera)
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
Mobo: HP ProBook 4540s (Clover)
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.

What is the DVMT-prealloc in BIOS set to? 0x01660002 requires 64mb.

This laptop use SeaBIOS/Coreboot, unlike legacy BIOS/UEFI, seems there is no setting for the DVMT :(
 
And if I check injectintel only, without any IG-platform-id, will stuck at boot where it show a message on top of the screening saying:

Debugger called: </SourceCache/GPUDriversIntel/GPUDriversIntel/Common/IONDRV/Intel/IVB/AppleIntelFramebuffer/AppleIntelController.cpp: Assertion failed: (0 == i) || ((pfbInfo->rangeStolen.physBase - pfbInfoPrev->rangeSt

Debugger not configured. Hanging

Default ig-platform-id for HD4000 mobile is 0x01660009.
 
Hello,
I have a Fujitsu Lifebook A512
CPU : I3 3110
GPU : HD 4000 1366 x 768

and with Clover bootloader and with ig-platform-id 0x01660003 i have the problem explained up,
i thinks it is a ports problem, with other ig-platform no ket are loaded, so no qe/qi, but if qe/qi loaded terrible glitches...

it's a eDP-DP port problem??
any idea?

thanks
