Package: dmidecode
Description: Dump Desktop Management Interface data
 The Desktop Management Interface provides a standardized description of
 a computer's hardware, including characteristics such as BIOS serial
 number and hardware connectors.  dmidecode provides a dump of the DMI
 data available from the BIOS.  It is used as a back-end tool by other
 hardware detection programs.
