- -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.
- -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
