The lack of 2nd PCIe and ethernet is expected behavior when the 2nd
socket is empty - please see the following
Please see 2nd 'NOTE' section 2.4 page 18
Looking at the system architecture section 2.2, page 9, it becomes clear
why this is so.
I think I will have to re-cap the board to restore the 2nd CPU socket to
eliminate this variable.
