  • Apparatus and method of allowing PCI v1.0 devices to work in PCI v2.0 compliant system
    Patent number: 6519555
    Abstract: The invention provides an apparatus and method of allowing a device to respond to a configuration query only if it is the true target of the query. In one embodiment of the invention, logic gates having two inputs are provided. The first input of the logic gates is connected to the signal of a bridge that selects a device when the address of the signal is referenced in the configuration query. The second input of the logic gate receives a signal indicating whether the local bus or the subordinate bus is being configured and the output of the logic gate is used to enable the device. In a second embodiment, certain signals designated to indicate the selection of a bus are used to enable devices to respond to configuration queries.
