Abstract
Embodiments of the present invention provide for initializing a device for use in a computer system. In one embodiment a BIOS routine reads a configuration register of each device in a computer system. The configuration register contains a device identifier indicating an oldest version of a device driver for controlling the device. The device identifier for each device is saved in a configuration data space. An operating system retrieves each device identifier contained in the configuration data space, and maps each device identifier to a corresponding device driver utilizing a registry. The operating system loads and causes execution of an initialization routine of each corresponding device driver mapped to each of the device identifiers.
