Hi I bought Panther for my iMac DV, and I started it up on the Panther CD, went thru the installation introduction, and it gave me an error saying it wasn't eligible on this machine - I'm guessing it was the firmware, but I clicked too fast and it disappeared. It began to reboot the machine, but hung on the spinning shut down logo. So... I force rebooted, and now it chimes (sometimes) then waits a few seconds and shuts down. I've got the CD out, held down every key combination, zapped PRAM (when it lets me, not often) and just powers off. What have I done? How can it be fixed? HELP!
