Abstract
Abstract Described is an improved method for undocking a structure having an optional number of tiers from a multilayer-dock structure constituted by docking a plurality of expansion units respectively having an intrinsic resource to a portable PC. To undock only a portable PC from a triple-layer-dock structure constituted by docking a first expansion unit and a second expansion unit to the portable PC, the first expansion unit is made to generate an undock event. The IDE device of the first expansion unit and the PCI device of the second expansion unit are separated from the control by an operating system by taking the undock event as an opportunity and the interfaces of the devices and are electrically separated. The operability is improved because it is possible to unitedly obtain an object to be undocked through both vision and operation.
