I just double checked my previous post.

In any case someone is desperate enough to use the contents of the 
miboot disk image that can be found at the above mentioned link, PLEASE 
DO NOT USE THE YABOOT VERSION CONTAINED ON THAT IMAGE ANY MORE!

It is far outdated and has evolved dramatically since. I have just 
looked into the disk image and realized that this version of yaboot 
will not work properly on most systems any more!

However, miboot will work as stated on OldWorld machines and will 
provide a boot method for a totally Mac OS free machine.
