40 * ID prom format.  The ``host id'' is set up by taking the machine
41 * ID as the top byte and the hostid field as the remaining three.
42 * The id_xxx0 field appears to contain some other number.  The id_xxx1
43 * contains a bunch of 00's and a5's on my machines, suggesting it is
44 * not actually used.  The checksum seems to include them, however.
