Sorry to be a bit on-topic here but... this question was never satifactorily answered.

When you're installing OS X on to a 604 mac, how the hell are you supposed to do it? Every time I tried, I get to the installing stage and my 9500 would try to boot from the OS X installer CD, which of course it can't because OS X wont boot up a 9500!

Am I missing some vital step here? I do recall following the instructions and they tend to just skip this bit.

Just so you don't think I'm hopeless, the installation worked perfectly on a Powerbook G3/333.
