you can use "any" OS9 installer CD - when it is at least as new as the one for the MDD.
the "universal" OS9 from this forum covers all machines http://macos9lives.com/smforum/index.php/topic,2109.0.html
IIO, thanks for your post. From the reading I've done, I was under the impression the 2003 MDD (and some other G4s) had a "unique" version of 9.2.2, and the only way to install it was to use the Restore set for the specific model. If my understanding is not correct, it certainly seems easier to use the "universal" 9.2.2 disk.
For some background, I have an iMac G4, a Quicksilver 733, a 2003 MDD, and a DP MDD. I got them a guy who just needed them gone, and they all have 10.4 or 10.5 installed, no OS9. I don't have any original disks. I'd like to get OS 9 installed and bootable on all of them. Can I do that by creating a partition and following the steps at "How to Install Mac OS 9 if you already have OS X Installed" (
http://macos9lives.com/smforum/index.php/topic,2109.0.html)? It would certainly be easier to use one "universal" 9.2.2 disk rather than trying to get a unique restore set for each computer!
Thanks again,
Marty
