Hi

the problem is not that they don't want to share their secrets but that most don't want searching.

You can tell me you've already tried, maybe maybe not, but the question is how could they succeed if they were not searching before ?

I don't know if that can help you, but you can base on this topic : http://www.insanelym...howtopic=275546


Good luck

Hmm, please keep in mind not every 6870 is the same and different manufactures will make minor changes to the port layout that can change what you may need to do compared to someone else with a 6870. That said, most likely config you will need is Gibba, Graphics Enabler=Yes and AtiPorts=5
I saw from another post you were able to restore a working version of the ATI6000Controller.kext, did you add your device ID to it's info.plist if it's not there already yet?

I got mine to work by going into my lion partition before my first boot on my mountain lion partition and removed
ATI6000Controller.kext. Then booted into 10.8 and went
through the first boot process and that was done i installed back ATI6000Controller.kext using kext wizard. Repair permisions and reboot. GFX is working perfect.

Install this kext with kext wizard or similar on S/L/E in your installer.
works for me.

Hi.

I am suffering from a white screen+cursor with my 6870. I tried adding those kexts to my installer's /S/L/E but I only get corrupted graphics. I have tried both GE on and off, Duckweed and Gibba, no success.

Any suggestions?

I don't have a 6870, but my understanding is you have to remove from installer, add back after installed. Should just need t remove the ATI6000 controller during install.

I am in the same boat! If I remove the ATI6000 controller from the S/L/E on installer USB. The installation doesnt even start! it gets stuck at the spining wheel below the apple logo.

I've got a 6850 and I get to the same grey screen and black arrow. I've not been able to get past it since.

Just a quick update for you guys, the AMD*.kexts are not included in the BaseSystem.dmg but are actually part of the Essentials.pkg. Not having the ATI6000 controller loaded during install will probably prevent these from being installed during installation as well. After install and once you've added it back and rebooted to your installed OS, just rerun the Essentials.pkg from within OSX or extract and install them using Pacifist.

holy {censored} i have so much more to learn.....

{censored} me I've tried every which way to get it to install. I actually got it to install once, but I forgot what method I used because I tried booting into it and couldn't get it, so by that time I'd forgotten what I'd done.

So I'm going to go back to the very first vanilla install and do that step by step.
Then I need to remove the ati6xxx kext from the installer drive.
Then I need to reboot and install.
Then I need to boot back into Lion, and install the kext on ML via the kext wizard.

Do I have that right?
