P8Z68-V PRO/GEN3 DSDT for BIOS v3402 (modified - 1155 repo)

I have been beating my head in on this. I have tried to follow Samisnake's tut for building your own, because that's the only advice I can seem to find to others' posts if anyone bothers to reply at all.

Problem is that there is no patch files for this it seems. I get a TON of errors when trying to compile using the the DSDT for the non-GEN3 version of this board. I will make a point of posting a request for the patch files on olarila, but I know that this motherboard is not that uncommon around here.

Shoot, I'd go back to older versions of DSDTs but they've all been pulled for my mobo with no clue as to when they'll return.

Please, please, please... If anyone's got any suggestions, throw them at me. My OS X install's been wonky at best and I'm wanting to completely redo it from scratch (scorched earth approach) and I'd appreciate any love given my way. Thanks.

Please upload the vanilla DSDT so that we can take a look at it.

Forgive my ignorance. I've extracted the DSDT but dont see how to save it as an AML file.The only option I have is to compile (this is without adding anything, which doing so provides a great deal less errors but there's still some.) I've tried copying the text and pasting into text edit but that doesn't seem to be working either.

Going to boot into windows to see if it can be done over there.

Thanks for your reply.

EDIT: Okay I believe I've got the vanilla file. I saw it pop up in the directory when I extracted, so I'm assuming it's it.

You can also save it as a .dsl file after you have extracted the DSDT so that there is no need to compile it first.

Ok, I have corrected the errors and applied the P8 (generic) BIOS 3xxx patch.

did you apply the alc892 patch

I changed layout-id to 0x37C but I didn't apply toleda's HD3000 HDMI patches because I don't know if this is needed too.

Thank you. I really don't care about the HDMI patch at all. It's not a critical thing to me really. I'll be back to report my results with a fresh install.

Amazing, and Samisnake, thank you for elaborating on that detail, I had no clue.

Alright, I'm back but not sure if the DSDT was completely successful or not.

I placed the aml file on the desktop before firing up multibeast. I selected the user DSDT option as well as the Nvidia 4xx/5xx kext installation option.

(I didn't select any audio or ethernet options as I wasn't sure if they were necessary at all.)

After running, I restarted the pc without the unibeast installer stick and it started up fine, first with the apple screen with black borders all around, then it going to full screen, so obviously the DSDT is working to some extent and the graphics are working as well!

However there is no audio output to choose from, nor any ethernet detected.

The second time around I've only selected hnak's e1000 kext as it's always worked for me and in the audio I tried using ALC8xxHDA.

Ethernet works without a reboot, still no sound output to choose from.

Third go on the audio, I've tried the ALC892 kext list under the Patched AppleHDA drop down.

Obviously I'm doing something wrong or I've missed something entirely.

Let me know what you suggest.

EDIT: Cancel all of that, I've gotten it sorted by a touch of searching here and found my answer!

At first I wasn't sure it took, but a restart sorted it right out.

Now the only thing I can tell that I am in need of is sorting out the bluetooth issue. I've already updated the BT firmware by installing the latest BT suite for Windows, so I'm assuming some other sort of trickery is in order here?

Again, thank you guys for your help and your efforts with the DSDT.

First check /var/log/kernel.log for sound assertions. To see the last 200 lines open Terminal and type:
Use to find out which kernel extensions have been loaded.

Next take a look at IORegistry with IORegistryExplorer and examine device HDEF. There's a lot of information available in the forum how to track down audio related issues. Especially toleda's threads about AppleHDA are very unseful.

With the DSDT installed you don't need ALC8xx.kext any more.
