          vpddecode - VPD structure decoder

          vpddecode [OPTIONS]

          vpddecode prints the "vital product data" information that
          can be found in almost all IBM and Lenovo computers. Avail-
          able items are:

          +o BIOS Build ID

          +o Box Serial Number

          +o Motherboard Serial Number

          +o Machine Type/Model

          Some systems have these additional items:

          +o BIOS Release Date

          +o Default Flash Image File Name

          Note that these additional items are not documented by IBM,
          so this is guess work, and as such should not be blindly
          trusted. Feedback about the accuracy of these labels is wel-

          -d, --dev-mem FILE
               Read memory from device FILE (default: /dev/mem)

          -s, --string KEYWORD
               Only display the value of the VPD string identified by
               KEYWORD.  KEYWORD must be a keyword from the following
               list: bios-build-id, box-serial-number, motherboard-
               serial-number, machine-type-model, bios-release-date.
               Each keyword corresponds to an offset and a length
               within the VPD record.  Not all strings may be defined
               on all VPD-enabled systems.  If KEYWORD is not provided
               or not valid, a list of all valid keywords is printed
               and vpddecode exits with an error.  This option cannot
               be used more than once.  Mutually exclusive with --

          -u, --dump
               Do not decode the VPD records, dump their contents as
               hexadecimal instead.  Note that this is still a text

               output, no binary data will be thrown upon you. ASCII
               equivalent is displayed when possible. This option is
               mainly useful for debugging.  Mutually exclusive with

          -h, --help
               Display usage information and exit

          -V, --version
               Display the version and exit
