Connecting drive to PowerPC Mac

From AwkwardTV

[edit] No Longer Booting

**MINE WAS FINE: Just so people with PPC Mac's know -- I have connected the Apple TV drive to my Power PC (Dual G5) and re-installed that into my Apple TV. Boots and plays files fine, ssh working as well (used openssh since I don't have an intel mac) Other should post some successes in the Discussion section as well since this is one occurrence and seems to be a anomaly

After hooking up the drive to a PowerPC based mac, the AppleTV can no longer boot (just get a flashing appleTV logo with a question mark over it). IF anyone has any ideas, or a solution to at least restore the drive, please post here. I think what happens is the disk is set to no longer be bootable. Does anyone know a command line command to set a partition to bootable?

[edit] Fix

I did not have this problem and I connected the drive to my PowerPC, but from the diskutility dump that you pasted it does not look like you have a Media partition created. You can't create this through DiskUtility though as it will break. You can use iPartition, or you can go add it with gpt:

# gpt add -s 309849759 -i 4 /dev/disk2

(you will want to change 309849759 to the # of blocks available on the drive. That # is the amount of free blocks I had on the 160 GB drive I upgraded to)
