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.
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.
In Windows Vista and later Windows operating systems, the HAL only supports ACPI, and ntdetect.com has been replaced by winload.exe, so that Windows will be able to control hardware resource allocation on every machine in the same way. Hardware profiles are also no longer supported in Windows Vista.
Windows 2000 is the first Windows to support hibernation at the operating system level (OS-controlled ACPI S4 sleep state) without special drivers from the hardware manufacturer. A hidden system file named " hiberfil.sys " in the root of the boot partition is used to store the contents of RAM when the computer hibernates.
Windows 2000 is a major release of the Windows NT operating system developed by Microsoft and oriented towards businesses. It is the direct successor to Windows NT 4.0, and was released to manufacturing on December 15, 1999, [2] officially released to retail on February 17, 2000 for all versions, and on September 26, 2000 for Windows 2000 Datacenter Server.
In computing, Intel's Advanced Programmable Interrupt Controller (APIC) is a family of programmable interrupt controllers.As its name suggests, the APIC is more advanced than Intel's 8259 Programmable Interrupt Controller (PIC), particularly enabling the construction of multiprocessor systems.
ReactOS 0.4.14 running the Firefox web browser. ReactOS is a free and open-source operating system for i586/amd64 personal computers intended to be binary-compatible with computer programs and device drivers developed for Windows Server 2003 and later versions of Microsoft Windows.
Although Windows 98 introduced the Windows Driver Model (WDM), VxD device drivers can be used under Windows 98 and Windows Me. Using VxD drivers instead of WDM drivers in Windows 9x may result in advanced ACPI states like hibernation being unavailable. VxDs are not usable in Windows NT or its descendants.
