1. A method of avoiding a conflict of respective controllers of a plurality of apparatuses connected to a system bus line which form a system, each controller controlling interaction, including connection and communication, of the corresponding apparatus with other apparatuses in the system, comprising the steps of:
- querying a user whether a target apparatus is to be set as a master apparatus of the system which monitors information of existing system configuration and controls the system configuration according to input from the user, the information of the existing system configuration, and information of predetermined available system configurations, the querying being controlled by a controller of the target apparatus, and the query being stored in a storage means of the target apparatus and being displayed by a display means of the target apparatus;
receiving an answer to the query from the user by an input means of the target apparatus;
determining whether the answer to the query is negative and if so, setting the target apparatus as a sub master apparatus in the system which monitors information of connection of other apparatuses to the sub master apparatus and controls communication between the master apparatus and the other apparatuses connected to the sub master apparatus, the determining and setting being controlled by the controller of the target apparatus; and
determining whether the answer to the query is affirmative and if so, executing a checking procedure to verify a presence of any other master apparatus by obtaining a response on the system bus line from the other master apparatus, the determining and the executing being controlled by the controller of the target apparatus.
