dmidecode - DMI table decoder

Syntax

dmidecode [OPTIONS]

Beschreibung

  • 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. It will first try to read the DMI table from sysfs, and next try reading directly from memory if sysfs access failed.
  • If dmidecode succeeds in locating a valid DMI table, 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 usually 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 laced 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.

Only display the entries of type TYPE. TYPE can be either a DMI type number, or a comma-separated list of type numbers, or a keyword from the following list: bios, system, baseboard, chassis, processor, memory, cache, connector, slot. Refer to the DMI TYPES section below for details. If this option is used more than once, the set of displayed entries will be the union of all the given types. If TYPE is not provided or not valid, a list of all valid keywords is printed and dmidecode exits with an error.

--dump-bin FILE Do not decode the entries, instead dump the DMI data to a file in binary form. The generated file is suitable to pass to --from-dump later.
--from-dump FILE Read the DMI data from a binary file previously generated using --dump-bin.
--no-sysfs Do not attempt to read DMI data from sysfs files. This is mainly useful for debugging.
