A method and apparatus for intelligent configuration register access on a PCI to PCI bridge (38) are provided. A read to configuration information of a connected PCI device (30) is identified. It is then determined whether the connected PCI device (30) is one for which the read should be trapped. If the read should not be trapped, the read is passed on to the connected PCI device (30). If the read should be trapped, the type of PCI device is determined for the connected PCI device (30). Data is then returned representing the configuration information in a format appropriate for the type of PCI device. In one aspect, the configuration information comprises the subsystem ID and subsystem vendor ID of the PCI device.
