It's an XPC860SRZP50C1.  I have another board with no ethernet which has an
XPC860ZP33C1 or an XPC860DEZP25A3 (this is on an older board).

The XPC860SRZP50C1 is a SAR processor though we are not using any of the SAR
capabilities on this board.  I hope this processor is fine.

I think the one I have is statically linked so I shouldn't need any shared
libraries.  It is the one that is in the mbx-root-min.tgz file.  The shell works
fine if I use initrd so it should work fine from an nfsroot (I would assume).

Now there is a good idea.  It's so obvious.  Why didn't I think of that.
Thanks.
