RiscPC Strong ARMv4 Adjust 4.39 with Unipod.

To ensure the RPC boots from the Unipod, I was about to reset the
relevant configuration. I looked in the Unipod help guide, the Risc OS 3
User Guide and its release notes and got 3 different orders of events.

Does this look right?

*Configure Boot
*idefs       	selects the file system
*drive <N>    changes the current drive to N . Mine  h-4
*Opt4,2 <N>   changes the option on the current drive to N  (0 or 2)
*configure filesystem  IDEFS

Not quite sure why the Unipod instructions appear to have the fiesystem
being set twice.

Any enlightenment gratefully received.
