Never got it to install using it's own DVD always got stuck or had SBBOD.
Had to connect to another G5 and place it in firewire target disk mode to install from "good" G5 dvd.
I have a dual 2ghz G5 that i wanted to clean off and start fresh. I wiped the drive with disk utility and tried to install os from tiger install dvd. G5 keeps hanging at install and also at disk utility. I've swapped both the osX install dvd disk and the entire dvd drive, but still hangs at os load or utility.
