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  de-
	      fined 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  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
       /dev/mem
