Information apparatus which can download and update its system program from a network

摘要

An information apparatus (IA) has a first storage device for storing a systems program. The systems program is used to control operations of the IA. The IA has a processor for executing the systems program, a communications device for handling communications between the information apparatus and a network, and a read-only storage device for storing a rescue program. When the processor executes the rescue program stored in the read-only storage device, the information apparatus utilizes the communications device to download a systems update program from the network to update the systems program of the information apparatus.
