In computing, the System Management BIOS (SMBIOS) specification defines data structures (and access methods) that can be used to read management information produced by the BIOS of a computer. [1] This eliminates the need for the operating system to probe hardware directly to discover what devices are present in the computer.
SMBIOS was originally named DMIBIOS. The Linux kernel and other modern operating systems such as the BSD family contain an SMBIOS decoder, allowing systems administrators to inspect system hardware configuration and to enable or disable certain workarounds for problems with specific systems, based on the provided SMBIOS information.

DMI can co-exist with SNMP and other management protocols. For example, when an SNMP query arrives, DMI can fill out the SNMP MIB with data from its MIF. A single workstation or server can serve as a proxy agent that would contain the SNMP module and service an entire LAN segment of DMI-capable machines.
AGESA was open sourced in early 2011, aiming to aid in the development of coreboot, a project attempting to replace PC's proprietary BIOS. [1] However, such releases never became the basis for the development of coreboot beyond AMD's family 15h, as they were subsequently halted.
System Management Mode (SMM, sometimes called ring −2 in reference to protection rings) [1] [2] is an operating mode of x86 central processor units (CPUs) in which all normal execution, including the operating system, is suspended.
Standard PC BIOS is limited to a 16-bit processor mode and 1 MB of addressable memory space, resulting from the design based on the IBM 5150 that used a 16-bit Intel 8088 processor. [ 8 ] [ 34 ] In comparison, the processor mode in a UEFI environment can be either 32-bit ( IA-32 , AArch32) or 64-bit ( x86-64 , Itanium, and AArch64).
In computing, BIOS (/ ˈ b aɪ ɒ s,-oʊ s /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).
