iMac with a Jammed CD!!!!

Hi, I've just tired to install windows XP on my I-mac (intel based) using Boot camp that came with Leopard OS. The install went as normal but suddenly the screen went black and the words "disk error" appeared. It also said "press any key to restart" When trying to restart nothing happens, nothing in the MAC book helps either apart from being able to turn the Mac off but once you turn it on the computer boots from the CD that is still in the drive and once again the same message appears "disk error" No matter what I try I can't get the XP disk out of the drive,

Does anybody know how you can remove a CD from a drive on an I-mac flat screen (intel based) when the keyboard is not responding????

found this on the apple site. It may work. I have never tried it.

First try rebooting your system and press the mouse button, while it is booting. The system shoulf eject the disk.
