Abstract: PROBLEM TO BE SOLVED: To provide a simple enclosure service using a high speed point-to point serial bus. SOLUTION: An enclosure service in a computer system comprising a host computer and at least one target device is supplied on a functional path, favorably a comparatively high-speed point-to-point serial bus between the host computer and at least one target device. At least one target device and the host computer respectively have a full power operation mode and an auxiliary power mode. The host computer generates the enclosure service command and transmits it, on the functional path, to at least one target device. At least one target device, even in the auxiliary power mode, can receive the enclosure service command and respond to it.

Abstract: AN ENHANCED PERIPHERAL COMPONENT INTERCONNECT (PCI) ARCHITECTURE FOR A DATA-PROCESSING SYSTEM (10) IS DESCRIBED. IN ACCORDANCE WITH THE METHOD AND SYSTEMOF THE PRESENT INVENTION, A PERIPHERAL COMPONENT INTERCONNECT (PCI) ARCHITECTURE FOR A DATA-PROCESSING SYSTEM COMPRISES A PCI HOST BUS (26), A NUMBER OF PCI LOCAL BUSES (20), AND A PCI HOT-PLUG BRIDGE (21). EACH OF THE LOCAL PCI BUSES HAS AN ADAPTER CARD SLOT (29A). THE PCI HOT-PLUG BRIDGE, CONNECTED BETWEEN THE PCI HOST BUS AND THE PCI LOCAL BUSES, IS UTILIZED FOR CONTROLLING POWER TO EACH OF THE PCI LOCAL BUSES, SUCH THAT A PCI ADAPTER CARD MAY BE REMOVED FROM OR ADDED TO ANYONE OF THE ADAPTER CARD SLOTS DURING POWER UP WHILE THERE IS PROCESSING ONGOING WITHIN ADAPTER CARD(S) SITUATED IN OTHER ADAPTER CARD SLOT(S).
