Device Drivers

What Is a Device Driver?

A device driver is a component that Windows uses to provide I/O services for and interact with an underlying device, such as a modem or network adapter. Rather than access the device directly, Windows loads device drivers and calls functions in the drivers to carry out actions on the device. The driver functions contain the device-specific code needed to carry out actions on the device. Device drivers for Windows Server 2003 are usually library files with .sys filename extensions.
Windows Server 2003 installs and configures device drivers automatically. This saves you from needing to allocate resources manually or check for conflicts in devices.
Windows Server 2003 checks for a digital signature during device driver installation and issues a message if the driver is not signed. Windows Server 2003 checks a database of known problem drivers when a computer is started or when a device driver is loaded; if a driver is located in the database of known problem drivers, that driver cannot be loaded, installed, or used on the computer.

The following table describes the components used for installing and managing devices and drivers.

Device Driver Dependencies and Interactions

Plug and Play
For automatic configuration of device drivers to occur, the system should have a BIOS compatible with Plug and Play. Plug and Play technology provides software and hardware support that enables the Windows operating system to detect and configure the hardware with little or no user involvement. This makes it easier to add and configure hardware on a computer running Windows Server 2003 without needing special knowledge about hardware configurations.

Power Management
Windows Server 2003 offers enhanced power-management features for desktop and mobile computers. The operating system supports the Advanced Configuration and Power Interface (ACPI) specification, which provides reliable power management and system configuration features. Devices and drivers designed in compliance with the ACPI specification work with the operating system to respond to or request changes in the system power state.
The following illustration shows a system-wide overview of how device drivers interact with other components of a system running Windows Server 2003.
