(There's no video for Mac OS 9.2.2 Universal (2002 edition) yet. Please contribute to MR and add a video now!)
This is a Bootable Universal install CD of Mac OS 9.2.2, US English. Suitable for most G3 & G4 Macintosh models (not all of them).
Mac OS CPU Software 4.9, includes the Mac OS ROM file v9.2.1
Note: This 2002 version is the best. For later G4's models such as MDD, please use this install CD ISO for unsupported G4's. Altough, there is a newer version of Mac OS 9.2.2 universal boot disk compiled in 2013 that is supposed to support most G3 and G4 models, it really doesn't boot a lot of them, while this 2002 one does.

It won't install on USB 2.0 Macs, but will fit most (not all) G3 and G4 models: Power Mac G4, Power Macintosh G3, iMac, iBook, PowerBook G4, and PowerBook G3 (except the original PowerBook G3).
