10.4 as a second system

I foolishly upgraded my G5 from 10.4.11 to 10.5 (for reasons that didn't pan out). Nonetheless, I am stuck with 10.5 on my main HD. I have software that will only work with 10.4 or less. I have a second HD. Can I (re)install 10.4 on my 2nd HD (as a second system) and then choose between the two drives for start up. And here is the real question. If I do install 10.4, will it automatically find all my old applications, settings, etc. and load them into 10.4?

Mac G5 Tower / Mac G4 Laptop, Mac OS X (10.4.10), None

As long as the external drive is formatted Mac OS Extended (Journaled), you should be able to install 10.4 on the external. You may need a Retail version of Tiger. Not sure if you can install Tiger on an exteral HD using original Tiger disks that came with your machine.

Unless you have a backup of your other Apps, settings and files, all you'll have is a new 10.4 System.

And yes, you can boot back and forth from one system to the other.
