Hi, I can boot os x from the same cd drive. I have tried 3 different os 9 disks and none seem to work. I zeroed the hard drive and when I installed os x I made sure to install the os9 drivers. I'm just having a heck of a time. I only needed to run a couple of programs, I guess I can do without. Thanks so much to all that have helped.
