VPDDECODE(8)                         System Manager's Manual                         VPDDECODE(8)

NAME
       vpddecode - VPD structure decoder

SYNOPSIS
       vpddecode [OPTIONS]

DESCRIPTION
       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 wel-
       come.

OPTIONS
       -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-se-
              rial-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 --dump.

       -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 --string.

       -h, --help
              Display usage information and exit

       -V, --version
              Display the version and exit

FILES
       /dev/mem
