Stuck at Black Screen After Booting Up?

[Anthonyx82x]

I'll take a screen shot, I tried uploading what I saved and it said it couldn't upload it for who knows what reasons?

Ok lets see if these Screen shots work and if the IOReg will upload after Zip'ing it.

I have always used the DSDT from this site for my board, it never gave me any problems until I updated to 10.7.4. I've tried PCIrootUID 0 and 1 and that never does anything.

Now I did not install those Nvidia Drivers from the website. I did install them earlier but with a combination of that DSDT I made and all this other mess. I had like 4 things going on at once. I was presented with a KP after that, oh and my graphics changed to 256Mb?

Well, what usually works for me is to start from a point that I know definitely works, and change one thing at a time. You said you were able to boot from rBoot. That is key. You need to figure out what is different between rBoot and your current setup, and work backwards from there, ONE THING AT A TIME. You can pursue this course if your DSDT edits do not work out for you.

org.chameleon.Boot.plist from rBoot Preboot.dmg:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<key>Legacy Logo</key>
<string>Yes</string>
<key>SMBIOS</key>
<string>rd(0,0)/Extra/smbios.plist</string>
</dict>
</plist>

Also rBoot does not use a patched DSDT.

Alternatively, you can try using the following EFI string in your org.chameleon.boot.plist:

<key>device-properties</key>
<string>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</string>

Use this with GraphicsEnabler=no, and a standard DSDT from the database with no graphics edits.

The DSDT edit was added to the wrong device, therefore it was actually not doing anything. You had it added to the PEGP device just as the guide showed, but your ioreg shows that the card is installed in the PEX4 device. In fact, you actually added the PEGP device that actually doesn't exist in your DSDT. Anyway, here is the properly edited DSDT for your configuration.

Edit: Make sure to set GraphicsEnabler=No because you no longer need it with this DSDT injection.

Also, keep in mind that the DSDT edit I made above will only work with your Graphics Card when it's installed in the same PCIe slot that it was in when you extracted your IOREG for me to look at. If you move the card to a different PCIe slot, you must look in IORegistryExplorer again and move the DSDT edit to the new device location.

Awesome, thank you very much. I'll have to practice with these DSDT edits. Actually. I'm going to need to get sound working again. Is there a easy edit for my Onboard sound? I had it originally working with using this AppleHDA and HDAenabler that was for Snow Leo and it worked. Now I can't get it to work. Maybe because I was using rBoot? But anyway. I'll try this out when I get home and see if it works. Just to be clear. I go to my multibeast, to then run the system utilities and my own DSDT and make sure I have in my plist Graphics enabler set to No, And then all should be working when I restart?

Yes it "should be" working. For the audio, the Gigabyte website shows that the GA-P55A-UD3 rev 1.0 has ALC888 audio. Your DSDT already has the HDEF audio infromation added, so you can use MultiBeast 5.0.2 and select Drivers & Bootloaders > Drivers > Audio > Realtek ALC8xx > With DSDT > ALC888 > v100302 Current. If that version doesn't work try the Legacy version.

For some reason those drivers never worked for me. The only way I could get sound working was to install that SL version that someone else patched. I'll have to look around more. I think I found them in the osx86 website.

Yeah I have this install on another drive right now, and I'm going to use this drive to test out everything until I get it all working, and then I'll see if I can fix the other one. I"m going to try this edited DSDT, see if my graphics work now, and then on to the sound issues once again.

 

[Anthonyx82x]

Well I added the edited DSDT in and still black screen. Now it wont even get past the Grey Apple screen, Just keeps spinning on both of my drives. I'm pretty much stuck now. Don't know what else to do. I can try a few more little things if I can even get back in. Might have to go to my Windows partiton and copy and paste original DSDT and see if that works.
