How do I get files off my AIX install tape onto disk?

[Tim Fredrick]

(Re: AIX3.1.5)  We need to be able to do a network installation and are trying
to set it up so that the directory /inst.images/risc_sys6000/3.1 contains
the proper files as described on page 70 of the Installation Guide for AIX
version 3 (3.1.5).

I can do a "restore -xf /dev/rmt0.1" and it begins to create an entire
directory structure with ./etc, ./bin, etc.  This is *not* what I want.  I
simply want to create ./bos.obj, ./Xrte, ./bosnet, etc.  Can anyone provide
any clues?  Thanks in advance.  --Tim
