I recently tried to install OS 10.4 on this old iBook I found. The iBook had OS 10.2 and ran fine however, I tried to install OS 10.4 and I keep getting a kernel panic. I can't eject the disk either.
At what point are you getting the kernel panic? My guess would be a fault CD drive, or a damaged CD. Although RAM could also be the issue. How much RAM do you have?
Hmm. Well, I think that's enough to run Tiger. Try an archive and install with the Tiger install disk. If that doesn't work, it might be a hardware problem. (I'm not very good with hardware problems, I'm a software guy 🙂 )
