ABSTRACT:
A computer main body has a system bus. The system bus is connected to a PCI-DS bridge. A docking station has a plurality of expansion devices for expanding the functions of the computer main body. The computer main body is attached to the docking station by means of the DS-PCI/ISA bridge of the docking station and the PCI-DS bridge of the computer main body, while the expansion devices of the docking station are separated from the bus of the computer main body. The computer main body outputs to the docking station an instruction for starting power supply, after having been attached. After switching on of the docking station has been detected, gates in the bus sides of the DS-PCI/ISA bridge and the PCI-DS bridge are switched ON.
