Abstract: A method and apparatus for updating the system configuration settings of a computer system Embodiments include a remote system configuration system that enables a user to update the system configuration of a target machine from a server machine over a network or similar communications system. Another embodiment includes a system configuration method using a bus master device to write system configuration data into a target computer system.

Abstract: Embodiments include an interrupt handling system to generate an operating system visible interrupt such as a message signaled interrupt or interprocessor interrupt by an advanced configuration and power management interface (ACPI) and ACPI source language infrastructure. The interrupt handling system may be used to service hot keys. This interrupt handling system allows for easy upgrading of system functionality by updating a driver.
