is a critical legacy standard in the evolution of modern computing architecture. Released by the Distributed Management Task Force (DMTF) around 2008-2009, this specification defined how system firmware (BIOS) presents management information to operating systems and third-party tools.
dmidecode -s system-manufacturer dmidecode -s smbios-version smbios version 2.6
is a standard developed by the DMTF (Distributed Management Task Force) that defines data structures and access methods for motherboard and system firmware to present management-relevant information about a computer. This includes details about the system manufacturer, product name, serial number, BIOS version, processor, memory devices, and more. Operating systems and management tools (e.g., dmidecode , Windows System Information) read SMBIOS data to identify hardware without probing hardware directly.

Before dissecting version 2.6, we must understand the . Developed by the DMTF (Distributed Management Task Force), SMBIOS is a standard that defines data structures and access methods for motherboard and system firmware to present management information to operating systems.
If you run dmidecode inside a default VirtualBox VM with an ICH9 chipset, you will likely see: SMBIOS 2.6 present. Last updated: 2026
Not directly. SMBIOS is a part of your system firmware (BIOS/UEFI). Updating your motherboard's BIOS to the latest version may increase the SMBIOS version number. For example, a Dell R710 with BIOS 6.6.0 might report SMBIOS 2.6, while a later BIOS 6.7.0 might report 2.7. However, you cannot "patch" SMBIOS independently; it is a hardware/firmware feature set.
