NAME

6       vpddecode - VPD structure decoder
7

SYNOPSIS

9       vpddecode [OPTIONS]
10

DESCRIPTION

12       vpddecode prints the "vital product data" information that can be found
13       in almost all IBM and Lenovo computers. Available items are:
14
15       • BIOS Build ID
16
17       • Box Serial Number
18
19       • Motherboard Serial Number
20
21       • Machine Type/Model
22
23       Some systems have these additional items:
24
25       • BIOS Release Date
26
27       • Default Flash Image File Name
28
29       Note that these additional items are not documented by IBM, so this  is
30       guess  work,  and as such should not be blindly trusted. Feedback about
31       the accuracy of these labels is welcome.

OPTIONS

34       -d, --dev-mem FILE
35              Read memory from device FILE (default: /dev/mem)
36
37       -s, --string KEYWORD
38              Only display the value of the VPD string identified by  KEYWORD.
39              It  must  be  a  keyword from the following list: bios-build-id,
40              box-serial-number,   motherboard-serial-number,    machine-type-
41              model, bios-release-date.  Each keyword corresponds to an offset
42              and a length within the VPD record.  Not all strings may be  de‐
43              fined on all VPD-enabled systems.  If KEYWORD is not provided or
44              not valid, a list of all valid keywords is printed and vpddecode
45              exits with an error.  This option cannot be used more than once.
46              Mutually exclusive with --dump.
47
48       -u, --dump
49              Do not decode the VPD records, dump their contents as  hexadeci‐
50              mal  instead.   Note that this is still a text output, no binary
51              data will be thrown upon you. ASCII equivalent is displayed when
52              possible.  This option is mainly useful for debugging.  Mutually
53              exclusive with --string.
54
55       -h, --help
56              Display usage information and exit
57
58       -V, --version
59              Display the version and exit
