Mountain Lion: HD3000/HD4000 with AMD or Nvidia, Working Together

[toleda]

It just shows NVIDIA GK106 and Display.

Post #1, see Integrated Graphics dsdt Injection (if Chimera HD3000/HD4000 injection is not working with GE=No)

Actually I've got the issue solved and my computer is back to the way it was using the GTX 480 and has Airplay available. I forgot to carry over a string for the HD4000 in my org.chameleon.Boot.plist.

Bios:
Init IGFX first

org.chameleon.Boot.plist:
GraphicsEnabler=YES (I know that toleda instructed to set it to No but if I do that my monitors sleep on boot, good thing I kept experiementing)
<key>device-properties</key>
<string>7f0000000100000001000000730000000200000002 010c00d041030a000000000101060000027fff04002c000000 4100410050004c002c00690067002d0070006c006100740066 006f0072006d002d0069006400000008000000000066011400 00006800640061002d0067006600780000000d0000006f6e62 6f6172642d31</string>

Im thinking of trying this out on my hack, however im abit confused about how to do it.

im on GA-H77N-WiFi with i7 3770 + a Geforce 660GTX

OS X is 10.8.3 and to get the hd4000 to run with GE=No i need a dsdt injection right?

question is just how do i make it / compile it?

Yes. See Post#1, Integrated Graphics dsdt Injection (if Chimera HD3000/HD4000 injection is not working with GE=No)
1. HDMI audio (Use Audio ID: 3, see [Easy Guide] ML: HDMI Audio/HD4000/7 Series MB)

wohoo it works now / semi

i just have one problem en clean boot my dock and menu line is on the wrong screen :/

anyway to fix

i should add nvidia uses dvi to vga and hd4000 uses hdmi

 

[mosser]

Hmm apparently today on boot it worked fine, going to monitor if it stays this way

 

[Zachwest]

Can I use VGA with the integrated graphics, and DVI with the GPU? Or the other way around?

 

[Zachwest]

i need help
when i try and boot it spins at the apple logo for ever
this is it booting verbose

 

[toleda]

this is it booting verbose

Not enough information in the -v screenshot. Verify BIOS and org.chameleon.Boot.plist are set correctly (post #1).

Hi, i've edited my DSDT with "hdmi_audio_ami_efi_hd4000.txt" and both HDMI Audio output (HD6870 + HD4000) just works fine, but when i install audio driver for ALC898 with Multibeast 5.3.1 (Drivers/Realtek ALC8xx/with DSDT/ALC898) the output of HD4000 doesn't show up in SystemPreferences, only the HD6870 HDMI audio works.
Is there any solution to get both HDMI outputs and my Realtek ALC898 together working?
