ACPI aims to replace Advanced Power Management (APM), the MultiProcessor Specification, and the Plug and Play BIOS (PnP) Specification. [1] ACPI brings power management under the control of the operating system, as opposed to the previous BIOS-centric system that relied on platform-specific firmware to determine power management and ...
UEFI Forum, Inc. is an alliance between technology companies to coordinate the development of the UEFI specifications. The board of directors includes representatives from twelve promoter companies: AMD, American Megatrends, ARM, Apple, Dell, Hewlett Packard Enterprise, HP Inc., Insyde Software, Intel, Lenovo, Microsoft, and Phoenix Technologies.
SFI provides access to a standard ACPI XSDT (Extended System Description Table). XSDT is used by SFI to prevent namespace collision between SPI and ACPI. It can access standard ACPI tables such as PCI Memory Configuration Table (MCFG). SFI support was merged into Linux kernel 2.6.32-rc1; [1] the core SFI patch is about 1,000 lines of code ...
The original EFI specification remains owned by Intel, which exclusively provides licenses for EFI-based products, but the UEFI specification is owned by the UEFI Forum. [8] [15] Version 2.0 of the UEFI specification was released on 31 January 2006. It added cryptography and security. Version 2.1 of the UEFI specification was released on 7 ...

Defective BIOSes may not set up interrupt routing properly, or provide incorrect ACPI tables and Intel MultiProcessor Specification (MPS) tables. The APIC can also be a cause of system failure when the operating system does not support it properly. On older operating systems, the I/O and local APICs often had to be disabled.
