the latest I've read this working on is 10.4.5 (but that may need to be updated anyways).

I'll keep looking but I suggest you read up on it too. do a search over at hackintosh.org and insanelymac.com as these are the only places I've seen this chipset referred to. Sorry mate.

Thanks for the help!!

appreciate the insightful and extremely quick responses!

I'm having trouble locating that version anywhere on the net. Any suggestions as to where I can look for older distributions/project files?

This forum neither condones nor promotes these sites so we can't specify here. Personally I wouldn't know right off the top of my head. I'm at work right now so I can't check it. PM me and I'll get back to you when I get home.

SO, I was able to get my hands on 10.4.5 (Universal Install AMD/INTEL)

When I boot, using the command: "rd=disk0s1 -f -x -v"

I get the following:
