Title: Peripheral driver installation method and system
Inventor: WILLIAMS BRETT
IPC: G06F9/445
Filed: 2002-03-04
Abstract: PROBLEM TO BE SOLVED: To provide an improved method for locating new peripheral drives and installing the new peripheral drivers in an OS. SOLUTION: This method has steps of creating a driver profile (block 14), creating a resources profile (block 16), and of looking to potential driver sources on a prioritized list for drivers that match the driver profile (block 22, 30 and 32). The driver profile may comprise information such as the peripheral model number, the OS version number, and the OS language determined through automated queries. The resources profile generally describes the resources available to the OS in terms of access to the potential driver sources on the list, and may be used to eliminate sources from the list that are not accessible. The remaining sources on the list are checked in descending priority order until a driver matching the driver profile is found (block 22, 30 and 32). Once a matching driver is found, it is installed on the OS (block 26).
