Just a thought,
	your system folder on the Jaz AIN'T "blessed unless its icon has a 
miniature mac symbol int he middle of it.  Is yours really Blessed?

To be sure it has been blessed, double click on the file finder inside the Jaz 
system folder.  You'll be told you can't open it, but the System folder will 
acquire its little mac icon.  Sorry to labour the point if you already did 
this.  But a mac won't boot from a disk with a valid system on it until the 
Finder can recognise the system folder properly.
