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.

Released in June 2009, revision 4.0 of the ACPI specification added various new features to the design; most notable are the USB 3.0 support, logical processor idling support, and x2APIC support. Initially ACPI is exclusive to x86 architecture; Revision 5.0 of the ACPI specification was released in December 2011, [ 15 ] which added the ARM ...
There are 28 CIM profiles supported in the DASH 1.1 specification. 9 new profiles were added and 4 profiles were updated in DASH 1.2 specifications. DASH uses the DMTF's Web Services for Management (WS-Management) protocol for communication of CIM objects and services. The web services expose a common set of operations for system management:
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.
If an expansion ROM wishes to change the way the system boots (such as from a network device or a SCSI adapter) in a cooperative way, it can use the BIOS Boot Specification (BBS) API to register its ability to do so. Once the expansion ROMs have registered using the BBS APIs, the user can select among the available boot options from within the ...
The Redfish standard has been elaborated under the SPMF umbrella at the DMTF in 2014. The first specification with base models (1.0) was published in August 2015. [3] In 2016, Models for BIOS, disk drives, memory, storage, volume, endpoint, fabric, switch, PCIe device, zone, software/firmware inventory & update, multi-function NICs), host interface (KCS replacement) and privilege mapping were ...
The BIOS Boot Specification requires that option ROMs be aligned to 2 kB boundaries (e.g. segments C8000h, C8800h, C9000h, C9800h, etc.). The first two bytes of the ROM must be 55 AA. [4] The third byte indicates the ROM size in 512-bytes blocks (e.g. 20h for 16kB ROM). And the fourth byte is where the BIOS begins execution of the option ROM to ...
