Hopefully this is the one. APPLEHDA.kext attached. AppleHDA.kext.zip

File below. From my \extra folder DSDT.zip

I am an amateur on this as well. I had a lot of assistance getting my machine running. That said, I would make sure you do the following if you haven't already: 1. Set your internal graphics memory to 64mb in your bios 2. Do not install your graphics card until you are able to boot off your hard drive into OSX. With the assistance I received from PMDSP I had a DSDT modified for my system. If you would like I could export mine out and post it here.

PMDSP, Per our conversation, what post installation files do I need to post here?

I had an hdaenabler898.kext. I deleted that along with the other applehda and reinstalled the one you gave me. It is now working. I hope it was o.k. to delete the hdaenabler898. I kept a copy of it just in case.

O.K. some followup on my journey: With the awesome assistance of Pmdsp I was able to get OSX up and running. Ended up having one bad memory stick (1 of 4 gb). Removed all but one, hoping to not use the offending one and the install went pretty smooth with pmdsp's help. When I updated to 10.8.2 lost audio. Again with pmdsp's suggestion, reinstalled applehda.kext and all was well with both my external speakers and youtube videos not playing. Last night I was running Mem86+ to find the offending stick. I found it and only placed the 3 good ones in the motherboard. Now unfortunately I lost audio again and youtube videos are not playing. Most say unavailable and the ones that are available play for 11 seconds and stop. Audio settings say no output device available. I removed one stick just to keep it even but that doesn't make a difference. Thought I would give it a shot though. Ran kextbeast with the applehda and appleacpiplatform on my desktop but this doesn't fix the problem this time.

I can't get the system to boot. I wanted to start over and reinstall the OS of the usb but I can't even get that to work. When I select USB on boot up it too doesn't get me to the install screen. It seems to be looking to the drive on boot up and I want it to only look at the USB stick. I don't know what is going on. Please don't tell me another corrupted usb stick. I didn't copy or move anything from it.

Use the unpatched DSDT file correct? Since their are compiler errors otherwise.

extracted DSDT file attached. extracted_dsdt.zip

I receive two errors and one warning when I try and compile the dsdt with the patch. When I hit "fix errors", the same message comes up, 2 errors and 1 warning. Errors are: 6906 Error Name already exists in scope (BUS0) 6909 Error Name already exists in scope (_ADR) 9654 Warning Statement is unreachable Tried extracting my own dsdt file and running the patch and I get three errors of which the fix errors does not fix them. Problem with brackets is one message.

O.k. I found it (DSDT Editor).

How do you apply the patch on the dsdt file?

Can you elaborate on how to delete that file?

O.K. Since posting this I did try running multishit with the no-DSDT option along with installing my Lan and Audio drivers, but upon rebooting the OS doesn't run. See attached for a similar image to what I receive upon rebooting. Additional reading on this topic appears to indicate that I need to do something with kext or other in order to get the system to boot up. This is where I am lost. Any explanation that I have read so far is not descriptive enough to assist a newbie like myself.

I didn't see a patch for this MB. If no other patch is compatible with this MB can someone create a patch for it?
