I believe only from an external firewire drive, not from an external USB drive, although someone will correct me if I'm mistaken.
Is it possible to install Tiger and boot from it from my Iomega external HD.
Don't have any real need to do it, just messing around.
Could not get it to work. When I boot from the Tiger install disk there is an exclamation mark on the external drive and it says "can not install OSX on this drive" or words to that effect.
