system-uuid, chassis-type, processor-family and processor-frequency.

defined by IPMI 2.0.

dmidecode's. Available keywords are bios-build-id, box-serial-number,
motherboard-serial-number, machine-type-model and bios-release-date.

the output of dmidecode to a given DMI type, or to extract a single
string from the DMI table. The documentation has been updated
accordingly.
- The default output of dmidecode was slightly modified to be more
easily readable by humans. This might break tools parsing its output.
Such tools may benefit from the new command line interface, although
this interface shouldn't be considered stable until version 2.8.
- (vpddecode) New command line interface.
- (vpddecode) 6 product names were added.
Version 2.6 (Mon Feb 28 2005)
