"""
 Supermicro DMI can be messed up.  They depend on the vendor
 to set the correct values.  The endusers cannot
 change them without buying a license from Supermicro.

 There are 3 serial numbers in the system

   1) System - this is used for the chassis information.
   2) Baseboard - this is used for the blade.
   3) Chassis - this is ignored.
