No luck for me, "Still waiting for root device", hehehehe. I know it may be of my Nforce 560 chipsets. I so tire with editting the AppleNForceATA.kext and inject again to iso image and burn, boot again because the latest kext was issue a message is does not support for my device 0x56010de.
Solution: WAIT FOR A NEW RELEASE OF SUPPORTING KEXT/S. I know that hihihihi
Good luck for those still trying to make it work.
