Hello.
I was recently given an old G4 iMac (Sunflower design) which the previous owner declared was faulty. I plugged in the machine and indeed, it didn't boot. The machine makes the usual chime and the screen lights up with the usual grey background and then it just hangs.
I suspected a HD fault, so connected it up to my Powermac G5 (2 x 2 Ghz) in target disk mode and the disk mounted no problem. Everything has now been deleted from the iMac drive (do I need to re-format, and if so, can I do in Target disk mode - Disk Utility wouldn't let me do this since its a mounted volume?) and Ive tried booting up with a retail Tiger 10.4 DVD. Holding down C during boot-up seems to kick the DVD drive in to life and the grey Apple logo appears, followed by a blue screen at this point it all looks like its going to boot the Tiger installer, but instead it just hangs There is no way to get the DVD out, other than re-booting into the firmware command prompt (using O F at boot up) and entering the command Eject CD. Sure enough, out pops the DVD.
Im now at a loss as to what to try next.
Is there anyway I can install a system folder onto the iMac HD via Target disk mode?
Anyone have any idea of what the fault could be please?
Seems a shame to bin this machine - in my opinion, its one of the most interesting Macs Apple has made, from a design view point, and its still in such good condition - way to good for chucking!!
Any help would be much appreciated, since Id love to get this machine up and running and in use as an iTunes duke box and second computer for my daughter and son to play around on
Thanks in anticipation!
