vpddecode - VPD structure decoder
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.
-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
vpddecode exits with an error. This option cannot be used more
than once. Mutually exclusive with --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.
