Actually I didn't answer your question because I'm not sure of the=20
current state of alternate partition support inside ofwboot.  It used=20
to be a catch 22 where you could only access the same partition as=20
ofwboot if you were accessing the same device.  (I *think* that's an=20
OF limitation on some versions of OF that got "canned" into a syntax=20
check in the ofwboot code.)  The situation was even muddier if you=20
were specifying a different device.

What I *can* tell you is that ofwboot intends (but didn't succeed) in=20
implementing the same device syntax as OF itself.  You need a : or a=20
, in order for it to know that you are giving a device path in=20
addition to the file path is one peculiarity.

As for which partition:  If you know which partition is number 10=20
then you can use any number of tools to find offsets.  All the=20
"ordinary" user partitions are in order after the driver partitions=20
that use up the first 8 or so.  In Drive Setup for example you can=20
use tab and shift-tab to walk through the list.  Under MacOS X you=20
can use pdisk to list them.  There is also a version of pdisk at=20
murphy.dyndns.org (or .com?) that you can get if you don't have MacOS=20
X.

Good luck.
