    • A system and method for scaling a bus based on a location of a device on the bus are disclosed. An information handling system includes a host bridge interfaced between a local bus and a peripheral bus operable to run at a plurality of bus speeds generated by the host bridge. A plurality of expansion slots are coupled to the peripheral bus and a bus switch is coupled to the peripheral bus between at least two of the expansion slots. Control logic is interfaced with the host bridge and the expansion slots. The control logic is operable to enable at least one of the expansion slots based on a signal received from each of the expansion slots by manipulating the bus switches.
    • 公开了一种基于总线上的设备的位置来缩放总线的系统和方法。 信息处理系统包括接口在本地总线和外围总线之间的主桥,其可操作以以由主桥产生的多个总线速度运行。 多个扩展槽耦合到外围总线,并且总线开关在至少两个扩展槽之间耦合到外围总线。 控制逻辑与主机桥和扩展槽接口。 控制逻辑可操作以基于通过操纵总线开关而从每个扩展槽接收到的信号来使能至少一个扩展槽。
