I have no clue what to say, or how to put kexts wherever they need to go, if I need to put them somewhere.

I pop in the Kalyway DVD, it loads up, takes a while

Get a bunch of error messages saying
"AppleNForceATA: warning: phy connection failed. status 0x00000000"

and then later on

SAM Multimedia: READ or WRITE failed, SENSE_KEY = 0x03, ASC = 0x11, ASCQ = 0x00"

that repeats a bunch.

Anyway, eventually it loads Mac OS X, but there it doesn't detect any storage devices to install onto.

Seems that SATA driver or kext or something needs to be put in a place somewhere.

bizzumpppp?
