Okay 10.6 is not playing nice. I edited the dsdt.aml to inject the audio and recomplied. I also followed the directions to port the AppleHDA.kext but after installing and rebooting the system hangs at the blue screen.

Decided to start over. Installed Ideneb 10.5.8. Working perfectly including the BMC9431 wireless pci-e card + ethernet + sound + full graphics support (i think).

I'd like to see if we can get a dedicated thread regarding the P-6860X, 6831 7805 as they're pretty much all the same.

So here's my set up.
Windows 7 on 320gb scorpio black.
Snow Leopard on 1st partition of 320gb scorpio blue. Leopard on 2nd partition of 320gb scorpio blue. Formatted to GUI.

I followed the guide from here (vanilla install for snow leopard).

Installed perfectly. Boot up from USB and then select my snow leopard drive. Start the 3.macloader. Finish and restart.

I boot up perfectly using -v arch=i386 (64-bit should work but if you read that thread there are a few problems regarding the macloader but it still works on 32bit)

Download efistudio and inject the string to com.apple.plist

Restart and mostly everything works.
External monitor with 1920x1200 resolution HDMI
External keyboard
External Mouse
Ethernet
Wireless (bcm9431 wireless)

What doesn't work
Sound
Laptop keyboard and touchpad
Bluetooth
Webcam


I am getting the restarting problem. I restart and it hangs up (forgot the exact thing it says) and takes a while (upto a minute) for it to completely restart and load the bootloader. I have not tried shutting down completely. Will do and let you know.

I will also attach my DSDT.aml if you guys like. Something to compare and see if everything is correct. I think my dsdt is causing no sound. Don't have it properly edited. Am trying again now
