Abstract: The motherboard includes a basic computing unit and an extension unit. The basic computing unit is provided with a basic component and an external interface. The extension unit is configured to extend a function of the basic computing unit. The basic computing unit is coupled to a second external interface of the extension unit through a first external interface on the basic computing unit. A conventional motherboard is split, and a basic computing unit that includes only a processor subsystem and an extension unit that extends input/output and management are formed by properly dividing the processor subsystem and a peripheral system. Impact of an extension component on the basic computing unit is reduced, and the extension component can be flexibly replaced based on an actual requirement.

Abstract: A computing device obtains a correspondence between a peripheral component interconnect express (PCIE) device identifier and an identifier of a port on the computing device, and the correspondence is persistent in the computing device. Then, the computing device determines a first port that connects a first PCIE device to the computing device, and allocates a first PCIE device identifier to the first PCIE device based on a first identifier of the first port and the obtained correspondence. Because the computing device allocates identifiers to PCIE devices based on the persistently stored correspondence between the identifier of the port and the PCIE device identifier, the computing device allocates same identifiers to the PCIE devices every time, so that the identifiers allocated to the PCIE devices are constant, thereby preventing the identifiers allocated by the computing device to the PCIE devices from changing and affecting access of services run on the computing device to the PCIE devices.
