Abstract
A method and apparatus of connecting an active computing device (15) to an active peripheral option (20) comprising the steps of making a physical connection (210) between the device (15) and the option (20) wherein the option (20) is communicably linked (44) to one or more peripheral devices (35, 40). A system interrupt signal is generated (240) and detected (250) by the system processor (17) causing all activity along the connection path between the device (15) and the option (20) to be suspended (250).
