ELECTRONIC DEVICE AND METHOD FOR CONTROLLING STATUS OF PCI INTERFACES

摘要

An electronic device includes a main board. The main board includes a number of PCI interfaces, an addressing unit, a determination unit, and a control unit. The addressing unit is configured for addressing addresses of each of the PCI interfaces of the main board from an address bus of the electronic device. The determination unit is configured for determining whether any PCI interfaces are not connected to corresponding PCI devices according to a value at the addressed addresses. The control unit is configured to turn off the PCI interfaces that are not connected to corresponding PCI devices. A method for controlling status of the PCI interfaces is also provided.

1. A method for controlling a status of Peripheral Component Interconnect (PCI) interfaces of an electronic device, the electronic device comprising a main board having at least one PCI interfaces, the method comprising:
addressing addresses of each of the at least one PCI interfaces of the main board from an address bus of the electronic device; determining whether any of the at least one PCI interface is not connected to a PCI device according to a value at the addressed addresses of the PCI interface; turning off the PCI interface when the PCI interface is not connected to a corresponding PCI device.
