I have a 1.25ghz eMac that was JUST running Leopard. It was running it over 5 years no problem. I had to reformat it though so I put the Leopard disc in.

It automatically ejects it because it cannot read DVD RW.

So I got an external USB 2.0 DVD RW drive and I saw the disc on the desktop. I restart and hold C... Computer boots normally. I restart and old option for startup manager. Disc does not show up.

So I reformat with the Panther disc. No problem. Now the DVD is not even recognized on the desktop. Try the other 2 options, same problem.

So why can I not install Leopard yet I had it on here less than 25 minutes ago.

I tried the Apple Superdrive and that only works with the new iMac's or Macbook Air. Fail on Apple.

Holding C at boot only works for the internal optical drive as long at it is still configured as it was when it left the factory. Your eMac can read Leopard, just only the authentic Apple disc, not a pirated or backup version.

You could also try to... I dunno... use a non RW DVD?

Is your leopard install disk original? I keep my originals and restored it on a DVD +RW discs. OSX is picky on DVD +RW discs some other brands work some other don't even with the branded ones.

It's a copy of the original disc and it does work. I used it on a Powerbook G4 and it installed no problem. It too, was running Leopard. I wanted to do a fresh install.

I did not have to use an external drive though because the Powerbook could read RW. The eMac cannot.

It should work with the eMac on an external drive...

I'm having somewhat the same issue. I've been looking for a solution for 3 days now and no one seems to know why it's not working, but I'll tell you what I've learned so far. Targeting Disk Mode is the best way to do it, but you need another Mac running leopard to do it, ipods seem to be the 2nd, FireWire external HD 3rd, then USB thumb drive (may be trickier, and most eMacs won't boot off USB).
I'm using the 3rd option and stuck on the last step. For some reason the hard drive's not showing up on the Startup Disk menu, or when I hold the option (Alt) key when it boots.
Did you format it to APM under the options button in the partition tab?

Put the disk in your PowerBook and start it in Target Disk Mode. Hold OPT at boot on the eMac and select the FireWire Target Disk in your PowerBook.
