I was guessing that there was a 0.1 or a 1.0 or whatever ever since I read http://homepage.mac.com/chinesemac/earlymacs/cd.html.'>http://homepage.mac.com/chinesemac/earlymacs/cd.html.

Yes, that is the problem created by Apple's attempt to reconcile their previously released system software with their new system software.

If you didn't read this already, http://homepage.mac.com/chinesemac/earlymacs/ clarifies the relationship between the official Apple numbering ( http://support.apple.com/kb/TA31885?viewlocale=en_US ) and the actual system files version numbers. Unfortunately, there is almost no official documentation which clarifies the System .97 is actually System 1.0. The chinesemac site mentions this in the narrative timeline. So yes you have 0.1, .97, 1.0 all referring to the same System file, further confused by "System Software" and "System Installation" designations of 1.0 which to completely different system files.
