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.
As of 2014, new PC hardware predominantly ships with UEFI firmware. The architecture of the rootkit safeguard can also prevent the system from running the user's own software changes, which makes UEFI controversial as a legacy BIOS replacement in the open hardware community.
DMI exposes system data (including the System Management BIOS (SMBIOS) data) to management software, but the two specifications function independently. DMI is commonly confused with SMBIOS, which was actually called DMIBIOS in its first revisions.
Software update managers are programs or that allow or ease the installation of patches. They may be built into operating systems or come as stand-alone programs. They may apply updates automatically or require user interaction. They may be able to update all of ones software at once or only software of specific manufacturers or alike.
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.

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).
American Megatrends Inc., doing business as AMI, is an international hardware and software company, specializing in PC hardware and firmware. [3] The company was founded in 1985 by Pat Sarma and Subramonian Shankar. [4]
Intel Active Management Technology (AMT) is hardware-based technology built into PCs with Intel vPro technology.AMT is designed to help sys-admins remotely manage and secure PCs out-of-band when PC power is off, the operating system (OS) is unavailable (hung, crashed, corrupted, missing), software management agents are missing, or hardware (such as a hard disk drive or memory) has failed.
