	c't 20/98, page 166 - PC configuration
		ACPI -- Advanced Configuration and Power Management Interface -- stands for a specification which is intended to offer users of Wintel PCs greater ease of use and a wider range of deployment options.
		ACPI specifies AML as an abstract programming language which is independent of the operating system and hardware, and which permits to control the functions of the board.
		ACPI therefore transfers the task of re-initialization to the device driver which has to have perfect command of the corresponding function.

	Advanced Configuration and Power Interface - Wikipedia, the free encyclopedia
		ACPI cannot be applied to older hardware; for it to work, the operating system, the motherboard chipset, and for some functions even the CPU need to be designed for it.
		ACPI uses its own ACPI Machine Language (or AML) for implementing power event handlers, rather than the native assembly language of the host system.
		Where hardware is non-conforming to ACPI, but claims to be, the software interoperating with that hardware is faced with a dilemma: Either it can be written to be ACPI-compliant, thus risking problems with the not-entirely-compliant hardware, or it can deviate from the ACPI standard to accommodate the hardware quirks.

	FreeBSD Documentation - 6.16 Using and Debugging FreeBSD ACPI
		ACPI is a fundamentally new way of discovering devices, managing power usage, and providing standardized access to various hardware previously managed by the BIOS.
		ACPI is present in all modern computers that conform to the ia32 (x86), ia64 (Itanium), and amd64 (AMD) architectures.
		ACPI maintainers do not usually maintain other drivers (e.g sound, ATA, etc.) so any work done on tracking down a driver problem should probably eventually be posted to the freebsd-current list and mailed to the driver maintainer.

	ACPI-CSET Software Requirements Document
		The ACPI is also seeking support from SSI multi-teraflop sites in providing cost effective, high-performance computing systems that will fully support climate simulations which may require thousands of processor hours for their completion, producing many terabytes of model output that need extensive analysis and inter-comparisons with other such simulations.
		One of the objectives of the ACPI implementation is to increase the pool of scientists involved in climate modeling and its related computational and applications aspects.
		ACPI activities can be grouped under four categories: model development, model application, regional climate prediction, and assessment studies; analysis is an integral part of all categories.

	ACPI - SWiK

	What is ACPI? - a definition from Whatis.com - see also: Advanced Configuration and Power Interface
		ACPI specifies how a computer's basic input/output system, operating system, and peripheral devices communicate with each other about power usage.
		ACPI must be supported by the computer motherboard, basic input/output system (BIOS), and the operating system.
		ACPI is in part a response to global concerns about energy conservation and environmental control.

	Advanced Configuration & Power Interface - Frequently Asked Questions
		ACPI defines hardware and software interfaces that enable OS-directed configuration and Power Management (OSPM) to enumerate and configure motherboard devices, and manage their power.
		ACPI 1.0 was released in December of 1996.
		ACPI CA can be licensed under the GNU General Public License or via a separate license that may be more favorable to commercial OSVs.

	ACPI4Linux - ACPI4Linux Overview
		ACPI (short for "Advanced Configuration and Power Interface") is a standard that defines power and configuration management interfaces between an operating system and the BIOS.
		The former was necessary since many hardware vendors are shipping their devices with bad firmware, which leads to lots of errors when trying to use ACPI on their systems.
		The goal is to have no need of end-user support at all: ACPI is something to make the operating system run better, but nothing which should have a user-visible identity of its own.

	Advanced Configuration & Power Interface - Downloads
		ACPI CA can be generated under three different OS development environments: Microsoft Windows, Unix, and Linux*.
		This includes conversion of the ACPI CA source code to the Linux kernel coding standard, and licensing under the GNU General Public License.
		This is suitable for systems programmers looking to use ACPI CA's functionality in their OS.

		ACPI allows control of power management from within the operating system.
		Of course, an ACPI patch should not be applied to a kernel that is already patched for ACPI.
		Although ACPI is included in the 2.6.x series kernels you should check to see if any patches have been released to fix bugs.

	[No title]
		ACPI, or Advanced Configuration and Power Interface, is a set of specifications for power management functions of devices and the OS interface to them.
		You may want ACPI if you are running a laptop and power conservation is a big concern, or if you want to put your desktop system to sleep during inactive periods, or if you want to monitor the temperature of various chipsets and to increase or decrease fan speed depending on those temperatures.
		In ACPI lingo, the CPU enters various P-States, P0 through Pn, where at P0, the CPU is running at its highest frequency and at Pn it runs at a lower frequency the greater the value of n.

	How Windows XP Determines ACPI Compatibility
		To override the default and force an ACPI installation, edit the Txtsetup.sif file, which is located on the Windows XP installation CD-ROM, to change the ACPIEnable value to 1.
		Note that ACPI functionality is relatively new, and functions are constantly being added by BIOS and system component manufacturers.
		ACPI does require the presence of some new hardware (an SMBus or I2c-compatible bus and other items) to make the system ACPI-capable.

	Fine Tuning Windows 98: How to Enable ACPI Support in Windows 98 - HelpWithWindows.com
		ACPI (Advanced Configuration and Power Interface) is an open industry specification co-developed by Compaq, Intel, Microsoft, Phoenix, and Toshiba.
		ACPI is not a fully mature standard, and any little bug in your BIOS or system drivers are going to have you want to uninstall ACPI support.
		An error code with the format 3xxx indicates an error within the ACPI driver event handler, usually when the event handler is running a control method as the result of a general-purpose event (GPE).

	Windows Instrumentation: WMI and ACPI
		Allow specific ACPI control methods to be called from a user-mode instrumentation data consumer or hardware configuration application--for example, from a control panel applet.
		Define standard data block formats, user-mode-callable ACPI control methods, events and their WMI GUID mappings for common data blocks, and callable control methods and events expected to be provided by all OEMs.
		Because very few ACPI standards exist for instrumentation, most of the ACPI instrumented features will appear differently on each vendor's product, and management applications will have to be "taught" to interpret the varying classes and methods.

		ACPI is an abstract hardware interface that provides a standard way to integrate power management in a PC system, including hardware, operating system and application software.
		The computer ACPI support is detected in the setup stage, but there are less frequent cases when ACPI is not detected and the Standard PC HAL is installed.
		The reason why ACPI is not installed on a computer with known ACPI compatibility may be a Microsoft known subtle incompatibility which can lead to hardware instability.

	Power and Resource Management
		Before ACPI was introduced, it was very difficult and inflexible for operating systems to manage the power usage and thermal properties of a system.
		Advanced Configuration and Power Interface (ACPI) is a standard written by an alliance of vendors to provide a standard interface for hardware resources and power management (hence the name).
		ACPI after a system has been brought up is not too useful, and in some cases can be fatal.

	HOWTO Fix Common ACPI Problems - Gentoo Linux Wiki
		However, when you try to use it in Linux, where the ACPI developers expect that the DSDT is written to comply with the standard (and the Intel ASL compiler), the buggy sections of the DSDT are unsupported.
		If after trying these fixes, your ACPI problems persist, then you may have found a bug in the ACPI driver code, which is still under active development.
		There is a boot parameter that you can pass to the kernel to tell ACPI to pretend that you are running Windows to restore the missing functionality, rather than rewriting your DSDT.
