I am back Dr.Hurt.
I tried both DSDT with both RAM option. Neither worked for me.
Is there anything I need to do extra ?
Here is process I am following to.
Created boot USB from 10.8.4 Mac App store App.
Boot from it.
Installed on one partition.
Booted with USB and selected fresh partition on which we installed ML.
Installed Chameleon with Chameleon Wizard App. I Installed Boot0hfs, 2255 revision.
Made some change to boot.plist file. I am attaching this boot.plist file.
Set SMBios to Mac Min 6,2
Placed your DSDT to Extra folder and also put SMBios.plist and boot.plist in Extra folder.
Reboot. Nothing difference. It is same checkers screen as with device-properties way. I am attaching screenshot of that also.
Please let me know whether it is supported or not. Also I found that i3 3220 has device id 0152 but you set 0166 in DSDT. Is that ok ?
Edit: First, delete AppleIntelGraphicsPowerManagement.kext and try again (boot with -f) with the same DSDTs from the previous post. If not, try with this DSDT attached below.
The id is normal. Its the HD4000 id which is also present in the kexts.
Give this last DSDT a test. I have set the id of the HD3000 IGPU as a last desperate attempt.
Tell me how it goes.
