Someone gave me the OS 9.1 and 9.22 discs. However, when I go to install the OS 9, the Classic menu opens and get this message "No Classic system folder: You do not have a version of Mac OS 9 installed that supports Classic. Install mac OS 9.1 or later." I'm unable to install the OS 9. I even checked the startup disk and OS 9 is not there. So any ideas on this one and what I can do to get OS 9 on there?
