I got my new laptop a week ago and have been struggling with its HD 4000 Graphics Card after Mountain Lion was installed. I use clover as bootloader and have been able to fix most of the problems at this point. Yet I still cannot turn on the QE/CI with my graphics card. I tried the "magic code", EDID Injection, also followed some DSDT modification methods in the forum, but still with no luck. So frustrated at this point. Can anyone help me with this? The dsdt file is attached. I made some patches on it (like Audio fix, DTGP etc.), but left the graphics part untouched. Along with it, I also put my Clover config file and my Display rom file in there.
Hardware information is as follows:
Wireless：Intel Centrino Wireless-N 2230 (substituted with a USB Wireless Adapter)
Touchpad：Elan (Multi-touch is malfunctional)
