I had an eMac that wouldn't take the Tiger DVD, so I've found this alternative (and rather simple) method to install Tiger on it...
Turn your iPod into a bootable Tiger installation disk. Here's how:
- Make a backup copy of your iPod if necessary (it will be erased in the next step!)
- Using Disk Utility, format (Erase) the iPod.
- Use the Restore feature in Disk Utility to create an image of the Tiger DVD on your iPod (drag the DVD into the source textbox; drag your iPod into the destination textbox).
- You can then plug your iPod in any Mac and launch the Install Tiger software, let it reboot, and follow the instructions to install it!
[robg adds: This tip could help those without a DVD drive in their machines, nor access to a traditional FireWire drive, install Tiger without sending back their media for CD versions.]
