if the CPIO was made with the -c option, the file information is in ascii.
(just od -c < tape  and see if it prints nice or cruddy).

If the cpio was made without the -c option, the file information is in 
native 3b2 binary ( chars, shorts, and longs), which will likely not be
the way a 386 likes it  (does anyone do things the Intel way?).  You 
can always transfer the cpio files to the disk using dd, and then write
a program to fix the shorts and longs.
