Abstract:
1. A data transmission coordinating method for communication between a central processing unit and a bridge chip in a computer system, comprising steps of: entering a coordinating state of the computer system; issuing a first signal by the central processing unit to a data transmission standard storage unit of the bridge chip, wherein the data transmission standard storage unit comprises a controlled switch communicating the bridge chip with the central processing unit, and a data-offering unit coupled to the controlled switch via a control end; processing the first signal into a second signal by the data transmission standard storage unit of the bridge chip and transmitting the second signal back to the central processing unit, wherein the second signal is differentiated by selectively conducting or shutting off the controlled switch in response to a control signal provided by the data-offering unit so as to inform the central processing unit of a first operable transmission standard of the bridge chip; and exiting the coordinating state of the computer system, and performing data transmission between the central processing unit and the bridge chip according to the first operable transmission standard in a first condition.
