Abstract:
A method of correcting a program in a ROM unit provided in electronic equipment, comprising the steps of:(1) connecting to the electronic equipment an external memory storing ROM correction data including a correction program for said ROM unit, a correcting point, and a version number of the correction program; (2) verifying the connection of said external memory, and storage of the ROM correction data therein by a data transfer unit in said electronic equipment, and communicating a connection state to a CPU unit in said electronic equipment; (3) comparing the version number of the correction program stored in said external memory with a version number of a correction program read from an internal memory and communicating the result thereof to said CPU unit; (4) displaying, in response to a command from said CPU unit, the version number of the correction program stored in said external memory and the version number of the correction program stored in said internal memory; (5) detecting a manual input command confirming the version number of the correction program stored in said external memory, and communicating the manual input command to said CPU unit; (6) said CPU, based on said manual input command, ordering said data transfer unit to transfer the ROM correction data in said external memory to an internal memory; (7) transferring said ROM correction data stored in said internal memory to a RAM unit within said electronic equipment by said CPU unit; and (8) executing the correction program in said RAM unit upon reaching the correcting point stored in said RAM unit.
