       vpddecode - VPD structure decoder

       vpddecode [OPTIONS]

       vpddecode prints the "vital product data" information that can be found
       in almost all IBM and Lenovo computers. Available 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 welcome.

       -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 vpdde-
              code  exits with an error.  This option cannot be used more than
              once.  Mutually exclusive with --dump.

       -u, --dump
              Do not decode the VPD records, dump their contents as  hexadeci-
              mal  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 --string.

       -h, --help
              Display usage information and exit

       -V, --version
              Display the version and exit
