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).
