Summary:PROBLEM TO BE SOLVED: To provide an improved computer system having an extension bus which can add a peripheral device to the system. SOLUTION: In a method registering newly added peripheral device to a computer system 100, the peripheral device has a response by transmitting a state message to a bus of the system 100 within a prescribed period after the asserting of a reset signal supplied to the peripheral device is released and in response to the access trial given to the peripheral device. Thus, it's possible to evade the stoppage of a function and also to evade the necessity to reboot of the system 100 to initialize a new peripheral device to the system 100. If a a response is generated within an initialization waiting time period shorter than the prescribed period, the peripheral device is allowed to transmit a trial response in an early stage. Furthermore, the peripheral device can respond to a non-configuration cycle right after a configuration is completed. The internal logic of the peripheral device is initialized after responded by a state message.
