SYNOPSIS

DESCRIPTION

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

OPTIONS

38       -d, --dev-mem FILE
39              Read memory from device FILE (default: /dev/mem)
40
41       -s, --string KEYWORD
42              Only display the value of the VPD string identified by  KEYWORD.
43              KEYWORD  must  be a keyword from the following list: bios-build-
44              id, box-serial-number, motherboard-serial-number,  machine-type-
45              model, bios-release-date.  Each keyword corresponds to an offset
46              and a length within the VPD record.   Not  all  strings  may  be
47              defined  on all VPD-enabled systems.  If KEYWORD is not provided
48              or not valid, a list of all valid keywords is printed and vpdde‐
49              code  exits with an error.  This option cannot be used more than
50              once.  Mutually exclusive with --dump.
51
52       -u, --dump
53              Do not decode the VPD records, dump their contents as  hexadeci‐
54              mal  instead.   Note that this is still a text output, no binary
55              data will be thrown upon you. ASCII equivalent is displayed when
56              possible.  This option is mainly useful for debugging.  Mutually
57              exclusive with --string.
58
59       -h, --help
60              Display usage information and exit
61
62       -V, --version
63              Display the version and exit
