ABSTRACT:
A method and apparatus for reprogramming a microprocessor through a serial port (18) is disclosed. An administrative computer (14) is connected to a serial port (18) on a machine (12) containing the microprocessor to be reprogrammed. A first sequence of signals is sent from the administrative computer (14) to the microprocessor (30) to change the microprocessor from a normal mode to a bootstrap mode. A new program is then loaded from the administrative computer (14) to the microprocessor (30). A second sequence of signals is sent from the administrative computer (14) to the microprocessor (30) to change the microprocessor (30) from the bootstrap mode to the normal mode.
