Abstract
A portable computer having two peripheral bays conforming to integrated drive electronics standard interface. A peripheral in one bay is always recognized as a master device and not a slave device. A peripheral in the other bay is recognized as a slave only when the first bay is occupied by a peripheral. This way, the situation never arises where there is a slave device without a master peripheral device. The bays may reside in the portable computer main body or in a docking station. A circuit can sense the presence or the absence of peripherals in the bays to thus prevent the situation of a slave peripheral being present when there is no master device.
