What bomb message are you receiving?
Try this:
Put the CD in
After you hear the Mac startup sound, press and hold the C key
(if that doesnt work, then try pressing and holding the C key and then starting up your Non-PC Macintosh)

(Or try the same thing with the S key)
Try that, and let us know what happens
