Hi, All,

 

Need some advice here.

Following this guide trying to get QE/CI working on a Lenovo X201i. 

 

Spec: CPU i3 380M, 1280x800 resolution internal LCD (Lenovo 4011), Mountain Lion 10.8.5.

          Boot Loader: USB key prepared using ##### (Chimera).
          MacBookPro 8.1 SMBIOS

 

          DSDT Injection for "AAPL,os-info" and "EDID".

         The following keys are added into org.chameleon.Boot.plist
         <key>GraphicsEnabler</key>
         <string>yes</string>
         <key>Graphics Mode</key>
         <string>1280x800x32</string>

 

After all the above work, I can boot OSX up and running in the native resolution(1280x800), but QE/CI are not enabled.

Check using ioreg -l and os-info and EDID are correct.

 

If I use the original kext (AppleIntelHDGraphics.kext) come with OSX, the extensions are not loaded.

 

but if I try to use the kext provided by GhostRaider in his "1st gen intel HD graphics" guide, the screen will be scrambled.

 

Install only the modified "AppleIntelHDGraphics.kext" would scramble the screen, install the patched "AppleIntelHDGraphicsFB.kext" doesn't help

the situation. It seems like giving the screen the wrong resolution data, horizontal lines on the screen are mismatched.

 

Using VNC to connect to the OSX, will get the same scrambled screen. So I think this would still be a driver problem.

 

Can anyone give some advice here?

My machine is 3680P3T, Core i5 M540.

 

I had been tring iATKOS L2; official 10.8; official 10.9 .... the installers fail to boot up.

 

 

Note:- here the screen from 10.9 installer boot up
