Discs 1,2,3 are the main installation discs to update the hard disc image
for RISC OS 3.7.

Disc 4 contains some Replay updates.

This installation must be implemented as 4 1.6M floppies.

Floppies 1,2,3 must be named RO370res01,RO370res02,RO370res03

This installation is only suitable for use with RISC OS 3.70 ROM. It *might*
work with the softload ROM image if you remove the RMEnsure UtilityModule
370, but we haven't tested this, do not guarantee it, and hereby state that
you try doing it at your own peril.
