Trying to "roll my own" DSDT for ASRock H77M-ITX: HELP! :-)

[krahim786]

1. H77MITX-patched-layout-id-392 Dsdt doesn't enable audio over hdmi on hd 4000. I tried. It works fine on hd3000
2. I used efi string and hdmi worked (video only)
3. I'm going to try editing the above Dsdt using the new Dsdt edit script you posted on your other thread. If successful, I'll post that Dsdt here.

OK. i have a working DSDT for ML with HD 4000 Graphics and HDMI OUT WORKING!!!! Thanks Meize for direction, BoomR for inspiration, and Toleda for HDMI out instuctions.

Attached here.

what else did you do in multibeast to get it running Krahim?
Did you install chimera 1.11?
Ik have the h77m ITX with 3570k and can not get it to work properly.
It will boot with graphics enabler = No and also with yes since im using your DSDT but i get not kexts loaded for hd4000 graphics.
So no QE/CI or native resolutions yet.
Do you use NullCPUPowermanagement and FakeSMC?

I installed everything, with easybeast everything seemed to work fine using all the specs in multibeast by BoomR so Thanks again! the problem comes with the bootloader which stucks at boot0 gpt but I searched and founded how to solve that, which is a problem of my hard drive, and the other problem is I can't figure out how to make sleep work. Tried sleepenabler and got kernel panic... Any ideas?

By the way, I Tried to use krahims dsdt and I had issues with the graphic card, so I finally decided not going after the hdmi audio, something which isn't important for me,

Again thanks in advance.

If you don't have a modified BIOS then you'll have to install the patched AppleIntelCPUPowerManagement.kext and remove NullCPUPowerManagement.kext in order to get speedstep and sleep.

ok it seems people with hd 4000 are still having issues so I'll try to explain my steps in more detail.


prelude - flash the modified h77m-itx UEFI *bios* (attached) you need to figure out how to do this. also, make sure to set your graphics card memory to 64mb in UEFI.

1. install ml using Unibeast method - no boot flags required (a few minutes into install, screen will go white, don't worry, let it restart on it's own)
2. after install, boot using unibeast drive into the newly installed OS.
3. run multibeast. use the dsdt file I attached for HD4000 audio/hdmi all working. checkmark everything you see in the attached image.
4. Open your Mountain Lion drive, go to /System/Library/Extension and delete the NullCPUPowerManagement.kext, AppleIntelCPUPowerManagement.kext.
5. Put the patched AppleIntelCPUPowerManagement.kext on your Desktop and install it using KextBeast.
6. Open multibeast, and reapply system utilities
7. add following key and string to /Extra/org.chameleon.Boot.plist
<key>Graphics Mode</key>

<string>1920x1080x32</string>
<string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000005006201140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string>

8. Run Chimera 1.11.0
9. Reboot and enjoy.

Thank you very very much Krahim, that helped a lot.

Everything is working, I just didn't used the key and string in the chameleon.boot.plist, because it was giving me some problems, as I'm not actually using FullHD resolution.
Also waking from sleep takes about 60 to 90 sec, anyone has figured out how to solve that?

Thank you again

I have a simular board but the Z77 version. THe Z77E-ITX.

Would this DSDT work for my board?

[samisnake]

for your chesty cough.

the answer to your question is generally no

 

[Digikid]

Had to say something. It is hard as hell to get any help around here.

However I digress....you said generally and that tells me otherwise. Possible then....
