yaboot boots os x, not linux, b&w g3

[Jeffrey Bruton]

Is there an OF command that will return the path last used to boot? If  
so I could boot to os x with the drive attached to the UltraTek,  
therefore obtaining the correct path to the hardware. It may be just  
the same, but to be sure I would like to try. I have been reading all  
kinds of OF info, but I didn't find such a command, though I could have  
missed it not being familiar with OF and FOURTH.
