Both standards are tightly related and developed by the DMTF (Desktop Management Task Force).Īs you run it, dmidecode will try to locate the DMI table. SMBIOS stands for System Management BIOS, while DMI stands for Desktop Management Interface. 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). While this is a good point in terms of report speed and safeness, this also makes the presented information possibly unreliable. Thanks to this table, you can retrieve this information without having to probe for the actual hardware. 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. Here is a brief description of the tool taken from its man page.ĭmidecode is a tool for dumping a computer's DMI (some say SMBIOS) table contents in a human-readable format. There is a special console tool dmidecode which utilizes sysfs to provide information about your motherboard.
