Ah! thank you, that clears it up.  I haven't bothered to set a system folder
on my HFS exchange disk. [Thanks also to BenH for that information.]

The Darwin binary that I downloaded installs onto an HFS+ volume from an
image (darwin.img) using the Apple Software Restore utility.  In my case the
supplied version of the Software Restore utility failed each time it was
started(error: can't locate HID, I think) and I had to use the one that came
with my system restore CD.

Yes, that's it.  The System Disk utility (version 3 is supplied) showed me
the info that it writes into OF, giving me enough info to modify the script.
In my case hd:13,\\:tbxi

I think that's just too many partitions :-)
