Problem not solved. While attempting

Problem not solved. While attempting to install DSL service using a provided CD I got the three whirrs eject response. Doing the “option”, “apple”, “p”, “r” keys on a restart had no effect this time. I called Apple technical support, who concluded that the CD drive is defective. They sent out a prepaid shipping container which arrived the following day. The system is now with Apple for repair. Fortunately, I purchased one of the new Mac Pro systems so am not experiencing the dreaded Apple withdrawal pains.
