Actually got around to putting the new board in this weekend. Seems to be working fine (did a lot of testing in windows), so I started working on OS X. I basically started from scratch, a clean install. But I'm using the exact same boot setup as I was before the breakdown. Same package installer of chameleon, same boot plist and smbios, same extensions. For some reason now I'm having trouble booting, though. It's not panicing or giving me kext errors, no errors at all. Right after I choose the volume to boot, it starts loading for less than half a second and then the computer pretty much turns off. Video goes away and all the fans start running at full speed. Any ideas what could cause that? Never seen a bad kext do it.
