dmidecode - DMI table decoder

As root type

DESCRIPTION
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 informa‐
tion 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 evolu‐
tions (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 dis‐
play 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.

pretty interesting..........

That's quite a bit of system info. Thanks for the tip. Smile
