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 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	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

FILES
