Something is not being done properly because the "Clean Install" option is supposed to make it possible to install a brand new version of the operating system without deleting the older or original installation and its contents (extensions, drivers, etc) . This was supposed to be to allow you to install a "non-corrupted" version of the operating system and then use it to determine what was causing the problems with the old system. You could then bring in "extra programs from third party developers" one at a time and test for the problem being resolved. A thought occurred to me that you might be able to make a copy of an OS-9 installation onto a USB drive and then "sneakernet" it to the machine you need it on. From there, it is just a simple drag and drop copy onto the hard drive and then select that system folder as your Classic environment in System Preferences. As an experiment, I just did that exact procedure with an iBook that would not recognize my OS-9.2.1 CD to install from. I made a copy of OS-9.2.2 from my personal G5 tower onto my flash drive, carried it to the iBook, drag and dropped the folder to the hard drive, and checked System Preferences/Startup Disk to see whether the OS-9 folder would be recognized. It was recognized, so I selected it and clicked on the restart button. The iBook restarted to OS-9.2.2 and shows the full contents of the hard drive when I open it. The OS-9 startup disk control panel gave me the choice of either system folder to boot from. I selected OS-X. 4.9 and restarted. It booted in OS-X.4.9. It looks like my drag and drop procedure worked for me, but I can't promise that it will work for you. I'm not a paper certified tech, just a knowledgeable Mac user who does volunteer refurbishing of donated equipment to put into school classrooms. My interpretation of the difference is that Apple has used the title "Classic" to denote all computers, operating systems, and software that is pre-OS-X and that "Native" applies to machines that are capable of booting to OS-9. There probably is a true company definition of those terms, but I haven't been exposed to it yet. In OS-X, programs that are OS-9 or earlier need to have the "Classic" environment running in order for the programs to operate, but it is not the full version of OS-9 and most of the system processes are being handled by OS-X resources. In the Mac User Group that I am a member of, we use the terms interchangeably and usually mean a pre-OS-X item when we say it.
