dmidecode

-->     dmidecode  is a tool for dumping a computer's DMI (some say SMBIOS) table contents in a human-readable format. This table contains a description of the system's hardware components, as well as other  useful  pieces  of  information such as serial numbers and BIOS revision. Thanks to this table, you can retrieve this information without having to probe for the actual hardware.  While this is a good point in terms of report speed and safeness, this  also  makes the presented information possibly unreliable.
