Add another install to darwin dual boot setup or change path to boot partition?

[willpower101]

I have a dual boot setup working:

disk0:

part1 vista (server 08 really)

part2 osx

part3 free space

 

disk1:

part1 free space

 

 

1. Can I just install another os, say xp, or another copy of vista on disk0 part3 and will the darwin bootmenu automatically pick it up, or is there something I have to edit?

 

2. Can I install another os on disk1 part1 and will darwin automatically pick it up?

 

3. Are there files located somewhere on the drive that I could edit to point the darwin bootload to a different disk OR partition instead of the windwos install on disk0 part1?

 

3b. If so, can I just add a new line to that file pointing to a third os?
