The partitioning on the 9153 is *hard* partitioning, controlled by a
configuration switch on the back.  It is a small rotary switch, and can
be used to select a number of different configurations.  To get one
large partition, set this switch to 0 and INITIALIZE the disk again.

It's the same file system HP-UX uses.  It has the same features and
requirements as such (i.e.  no contiguous block requirement).
