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:

       • 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

FILES

       /dev/mem
