DMTF Releases Updated SMBIOS Standard

The latest release of the premier standard for delivering management information via system firmware, System Management BIOS (SMBIOS) Reference Specification, Version 3.1, is now available from DMTF.

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. New in Version 3.1, SMBIOS now includes support for mini PCIe and Trusted Platform Module (TPM) devices, and adds new chassis types for Internet of Things (IoT) gateways, as well as embedded, mini and stick PCs. In addition, the standard has been updated to support extended BIOS ROM size and cache sizes greater than 2047 MB.

Since its release in 1995, the widely implemented SMBIOS standard has simplified the management of more than two billion client and server systems. By extending the system firmware interface, SMBIOS can be used with management applications and eliminates the need for error-prone operations, such as probing system hardware for presence detection.
