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).
