I recently purchased a new 15" PB. It's an awesome machine. No problem there. However, It's replacing a Rev. A 12" in PB that I purchased reconditioned from apple.com a little over a year ago. The 12" PB came with the original Jaguar software and a Panther "upgrade" DVD. To prepare the 12" for sale on ebay, I tried to reinstall the original software. I inserted the Jaguar CD and clicked the install option and got the 'You need to restart your computer' message in four different languages. So, I restarted the computer using the power button and got the same message. I then repeat this four more times and get the same result, and I can't eject the CD. How do I end this cycle? Thanks in advance.
