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 comput‐
       ers. Available items are:

       · BIOS Build ID

       · Box Serial Number

       · Motherboard Serial Number

       · Machine Type/Model


       Some systems have these additional items:

       · BIOS Release Date

       · 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.


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-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 --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
