A system for synchronizing configuration information in a plurality of data processing devices using a common system interconnect bus. The present invention provides a method and apparatus for enforcing automatic updates to the configuration registers in various agents in the data processing system. A node controller is operably connected to a system interconnect bus and a switch. A plurality of interface agents are connected to the switch, with each of the interface agents comprising a configuration space register, a configuration space shadow register and a control and status register (CSR). A token ring connected to the node controller is operable to transmit data from the node controller to a plurality of interface agents connected to the token ring, thereby providing a system for updating the various configuration registers in each of the agents.
