A method and related apparatus for different lane and access port configurations of a bus. Such different configurations can apply to different applications requirements. In a preferred embodiment of the invention, a chipset can configure 18 lanes to 4 access ports of a peripheral communication interconnect express bus for selectively 4 different configurations. A first configuration provides single access port with 16 lanes, and two access ports for each has one lane. A second configuration provides two access ports for each has eight lanes, and two access ports for each has single lane. A third configuration provides one access port with eight lanes, two access ports for each has four lanes and another one access port with single lane. And a fourth configuration provides four access ports for each has four lanes.
