thought so...

that line means boot yaboot from the root directory, certianly the
most reliable method i have found other then hd:,\\:tbxi (which only
works on CHRP scripts with a properly blessed directory) 

the first notation means to load the file from the blessed directory,
which if there isn't one will fail.  macos tends to remove the
blessing from non-macos directories.

does darwin still use UFS or ffs for its default filesystem?  if so it
probably uses a bootstrap partition of type Apple_Bootstrap or
Apple_BootROM setup pretty much the same way i advocate (that is where
i got the idea, from OSX server) if it does still use this partition
you should be able to add a reference to it like so:


to your chooser script.  where 6 is the real partition number of the
darwin bootstrap partition.
