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.  It must be a keyword from the following list:
	      bios-build-id, box-serial-number, motherboard-serial-number, machine-type-model, bios-release-date.  Each key‐
	      word  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 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
