Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.
The ASPI manager software provides an interface between ASPI modules (device drivers or applications with direct SCSI support), a SCSI host adapter, and SCSI devices connected to the host adapter. The ASPI manager is specific to the host adapter and operating system ; its primary role is to abstract the host adapter specifics and provide a ...

The sound card Sound Blaster AWE32 PNP CT3990 had a Plug-and-Play ISA Bus interface chip (large square chip, mid of bottom row).. The term Legacy Plug and Play, [1] also shortened to Legacy PnP, [2] describes a series of specifications and Microsoft Windows features geared towards operating system configuration of devices, and some device IDs are assigned by UEFI Forum.

SCI from the Embedded Controller to inform the ACPI driver (in the OS) of an ACPI Event; As a core system component, the embedded controller is always on when power is supplied to the mainboard. To communicate with the main computer system, several forms of communication can be used, including ACPI, SMBus, or shared memory.
Some system components (such as filesystem, GWES (graphics, windowing, events server), [6] device driver manager) have been moved to the kernel space. The system components which now run in kernel have been converted from EXEs to DLLs, which get loaded into kernel space. New virtual memory model. The lower 2 GB is the process VM space and is ...
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.
Support for all ACPI 2.0 and 3.0 processor objects. User configurable system cooling policy, minimum and maximum processor states. Operating system coordination of performance state transitions between dependent processors. Elimination of the processor dynamic throttling policies used in Windows XP and Windows Server 2003.
