I have a E6400, P8400 cpu, 2gb ram, 200gb sata hdd, using a 65w universal adapter, there is no lcd hooked to it (just a LCD w/ displayport to DVI adapter). No battery either.. nvidia quadro graphics as well. I have followed all directions and when i try to use the usb to install ml to the e6400 it KPs on the screen w/ the cog wheel (with the apple). Also kernel backtrace says IOACPIFamily.. I have BIOS version 34 (latest), also when i used my hack to create the usb, i used a 10.8.4 image, does this matter? I did add the extra in with the installer usb as posted in this thread. Also set the BIOS to defaults and changed the IRRT setting to AHCI. I do not know what i am doing wrong. Any thoughts?
