UPDATE-Leopard 10.6 on Old ATV
I was able to run the Bliss Command. When I reconnected the ATV to my TV, it looked like it started up with OSX. I saw the apple logo and pin wheel. After a few seconds the system seemed to reboot. It cycled through this 6 times and then reverted to starting up the ATV OS.
I have two drive partitions. One called "Media" (OSX installed on this one). The second called "OSBoot".
When I have this drive plugged into my MacBook, and restart, I boot successfully off this connected drive.
So now, I'm wondering if I don't have all the files in the correct directories. I feel like I'm really close to having this solved.
Thanks for any help!
