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 Windows Dev Center - Hardware pages explain upper and lower filter drivers in detail. [2] For example, the generic USB camera (UVC) driver usbvideo.sys is a function driver, while the bus driver handles USB data from the host controller devices. A lower level filter modifies the behavior of the camera hardware (e.g. watching for interrupt ...
There is the ability to opt out of APM control on a device-by-device basis, which can be used if a driver wants to communicate directly with a hardware device. Communication occurs both ways; power management events are sent from the BIOS to the APM driver, and the APM driver sends information and requests to the BIOS via function calls.
IRQ 2/9 is the traditional interrupt line for an MPU-401 MIDI port, but this conflicts with the ACPI system control interrupt (SCI is hardwired to IRQ9 on Intel chipsets); [6] this means ISA MPU-401 cards with a hardwired IRQ 2/9, and MPU-401 device drivers with a hardcoded IRQ 2/9, cannot be used in interrupt-driven mode on a system with ACPI ...
Device Manager was introduced with Windows 95 and later added to Windows 2000. On Windows 9x, Device Manager is part of the System applet in Control Panel. On Windows 2000 and all other Windows NT-based versions of Windows, it is a snap-in for Microsoft Management Console. The executable program behind the Device Manager is devmgmt.msc.
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.
SeaBIOS is an open-source implementation of an x86 BIOS, serving as a freely available firmware for x86 systems. Aiming for compatibility, it supports standard BIOS features and calling interfaces that are implemented by a typical proprietary x86 BIOS.
WMI extensions for WDM offer a set of Windows device driver interfaces for instrumenting data within the driver models native to Windows, so OEMs and IHVs can easily extend the instrumented data set and add value to a hardware/software solution. The WMI Driver Extensions, however, are not supported by Windows Vista and later operating systems. [11]
