Windows operating systems use acpi.sys [28] to access ACPI events. The 2.4 series of the Linux kernel had only minimal support for ACPI, with better support implemented (and enabled by default) from kernel version 2.6.0 onwards. [29] Old ACPI BIOS implementations tend to be quite buggy, and consequently are not supported by later operating systems.
Advanced power management (APM) is a technical standard for power management developed by Intel and Microsoft and released in 1992 [1] which enables an operating system running an IBM-compatible personal computer to work with the BIOS (part of the computer's firmware) to achieve power management.
Using a standardized interface and protocol allows systems-management software based on IPMI to manage multiple, disparate servers. As a message-based, hardware-level interface specification, IPMI operates independently of the operating system (OS) to allow administrators to manage a system remotely in the absence of an operating system or of the system management software.
Version 1.4 of the specification was released on July 1, 1995, which added extended configuration tables to improve support for multiple PCI bus configurations and improve expandability. The Linux kernel and FreeBSD are known to support the Intel MPS. Windows NT are known to support MPS 1.1 and, through later Service Packs, also MPS 1.4.
Vector numbers 0 to 31, out of 0 to 255, are reserved for exception handling by x86 processors. All Intel processors starting with the P5 microarchitecture ( P54C ) have a built-in local APIC. [ 6 ] [ 7 ] However, if the local APIC is disabled in a P5 processor, it cannot be re-enabled by software; this limitation no longer exists in the P6 ...

Some operating systems, notably Windows Vista, Windows 7, Windows 8, Windows 8.1 and Windows 10, do not configure themselves to load the AHCI driver upon boot if the SATA controller was not in AHCI mode at the time the operating system was installed. Although this is an easily rectifiable condition, it remains an ongoing issue with the AHCI ...
Panther Point is the codename of a PCH in Intel 7 Series chipsets for mobile and desktop. It is most closely associated with Ivy Bridge processors. These chipsets (except PCH HM75) have integrated USB 3.0. [16] This has the following variations: BD82C216 (PCH C216) Workstation/Server; BD82H77 (PCH H77) Desktop Home
