installing OS9 onto powermac G3 from iMac CD

About a year ago, I purchased an OS9 installation CD off of ebay. When I received it in the mail, it turned out to be an iMac OS9 CD along with instructions on how to use it to install OS9 onto a powermac desktop computer. I followed the instructions and had no problems using the os for about a year. However, recently I've had some extension conflict problems and I tried to reinstall OS9 from the cd but I couldn't get the installation program to run. I have moved twice since I bought the cd and have lost the instructions. Does anyone out there know the procedure for using an iMac CD to install OS9 onto a beige powermac G3 desktop?

The site www.os9forever.com has made available a couple of tools for fooling install disks. This link will download a CSM to change temporarily the machID of a machine to one the installer CD will accept. http://www.ralstonweb.com/cgi-bin/os9foreverblog.cgi/docs/081203-1.html.
