Quadruple Boot System

[David Hacker]

I was able to get one bootstrap partition and yaboot to boot OS 9, OS 
X, YDL, and Mandrake 9.1 just by editing the yaboot config file 
manually.  The trick is to specify the exact localtion of the kernel 
you want to load and pass the root= arg to the kernel.
