Open Firmware tries the first partition that is marked bootable.

Exactly what it does next depends on the firmware version, but clearly
in your case it stops booting.

Turn off the bootable flag using a partitioning program, ensure you
are using latest firmware Q7B30, and attach a serial console for
further debugging.

If you can tell me how to reproduce the symptom, then I'm quite sure I
can get it fixed.  I certainly can't afford to download 700 GB or 1 TB
to do that though.

I'm happy to work with whoever has the drive and an XO-4.

The nature and value of the content has no relationship to the
diagnosis process, but is interesting regardless.
