Wow great guide. I have my d630 running ML now. I have a 1395 card which i got to work with a kext in another thread. I do not have sound though. It shows no sound devices in settings. I tried to use voodoo 2.7.3 from multifail but that fails to install then i get a KP about audio after that.
Also how are booting off the hdd after install. I get boot error unless i install a bootloader.
Got it to work, typing on it now.
Installed chameleon alone not using multifail and that made the sound not go away.
thanks!
