It needs to be a full retail disc and OS 9.2.2.
True, but it depends on what version of OSX he's running. 10.4, last version, would only work with 9.2.2 but older versions of OSX worked with older versions of OS9. Also, it doesn't have to be 9.2.2 to boot the machine to OS9, just to run classic from 10.4.
