SMBIOS

Working Group Chairs

Sai Chaganty, Intel Corporation

Working Group Description

SMBIOS is the premier standard for delivering management information via system firmware. Since its release in 1995, the widely implemented SMBIOS standard has simplified the management of more than two billion client and server systems.

For OS-present, OS-absent, and pre-OS environments, SMBIOS offers motherboard and system vendors a standard format to present management information about their products. By extending the system firmware interface, SMBIOS can be used with management applications that use DMTF’s Common Information Model (CIM) or another technology, such as SNMP. It eliminates the need for error-prone operations, such as probing system hardware for presence detection.

Originally designed for Intel® processor architecture systems, SMBIOS now includes support for IA-32 (x86), x64 (x86-64, Intel64, AMD64, EM64T), Intel® Itanium® architecture, 32-bit ARM (Aarch32) and 64-bit ARM (Aarch64).

Get Involved

DMTF members are encouraged to contribute and access the work of the SMBIOS Working Group via its private, members-only workspace. Non-members, learn more and join DMTF to participate.
DMTF welcomes feedback on our standards, but requires that individuals submitting comments first agree to our DMTF Feedback Policy.

Open Source Projects using DMTF SMBIOS Technologies

DMTF technologies are leveraged in numerous third-party open source projects. If you are aware of any additional projects using DMTF technologies that are not included below, please contact us so we can add them to the list.

Open Source Project	Description of Tool
Coreboot	Coreboot is an open-source firmware implementation for x86 and ARM, and includes code to generate the SMBIOS table.
dmidecode	Dmidecode (C) is a command-line utility to view the SMBIOS table. It supports multiple operating systems, including Linux and FreeBSD.
EDK2	EDK2 is the standard development framework for UEFI/PI. It includes code to generate the SMBIOS table, and a table viewer (smbiosview) that can be run from the UEFI shell.
Linux	The Linux kernel contains an SMBIOS decoder and makes the SMBIOS table accessible to programs through the /sys virtual filesystem.
Python dmidecode	Dmidecode (Python) reports information about your system's hardware as described in your system BIOS according to the SMBIOS/DMI standard.
