METHOD AND APPARATUS FOR INITIALIZING A COMPUTER INTERFACE

摘要

According to one embodiment, a computer system includes a first hub agent and a hub interface coupled to the first hub agent. The first hub agent is adaptable to sample the hub interface in order to detect the presence of a second hub agent upon initiation of the computer system. In a further embodiment, the first hub agent comprises a presence detect module and control logic coupled to the presence detect module. The control logic responds to a central processing unit (CPU) poll request if the second hub agent is detected and does not respond to the CPU if the first device is not detected.
