dmidecode - DMI table decoder

This requires root privilege

#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.

       The DMI table doesn’t only describe what the system is currently made of, it also can report the possible evolutions (such
       as the fastest supported CPU or the maximal amount of memory supported).

       SMBIOS stands for System Management BIOS, while DMI stands for Desktop Management Interface. Both  standards  are  tightly
       related and developed by the DMTF (Desktop Management Task Force).

       As  you  run  it,  dmidecode will try to locate the DMI table. If it succeeds, it will then parse this table and display a
       list of records like this one:

       Handle 0x0002, DMI type 2, 8 bytes.  Base Board Information
               Manufacturer: Intel
               Product Name: C440GX+
               Version: 727281-001
               Serial Number: INCY92700942

       Each record has:

       · A handle. This is a unique identifier, which allows records to reference each other. For example, processor records usu-
         ally reference cache memory records using their handles.

       · A  type.  The  SMBIOS  specification defines different types of elements a computer can be made of. In this example, the
         type is 2, which means that the record contains "Base Board Information".

       · A size. Each record has a 4-byte header (2 for the handle, 1 for the type, 1 for the size), the  rest  is  used  by  the
         record  data.  This  value  doesn’t  take  text strings into account (these are placed at the end of the record), so the
         actual length of the record may be (and is often) greater than the displayed value.

       · Decoded values. The information presented of course depends on the type of record. Here, we learn about the board’s manufacturer, model, version and serial number.
