SMBIOS System Management BIOS
System Management BIOS (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).
Open Source Projects using DMTF SMBIOS Technologies
|Open Source Project||Description of Tool|
Coreboot is an open-source firmware implementation for x86 and ARM, and includes code to generate the SMBIOS table.
Dmidecode (C) is a command-line utility to view the SMBIOS table. It supports multiple operating systems, including Linux and FreeBSD.
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.
The Linux kernel contains an SMBIOS decoder and makes the SMBIOS table accessible to programs through the /sys virtual filesystem.
Dmidecode (Python) reports information about your system's hardware as described in your system BIOS according to the SMBIOS/DMI standard.
