vpddecode - VPD structure decoder
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
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,
Each keyword corresponds to an offset and a length within the VPD
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
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.

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
