ABSTRACT:
Method and apparatus for altering an executable file stored in a random access memory on a designated interactive network having a local area network interface comprises activating a LAN communication program. The communication program operates to broadcast an inquiry through the local area network for the designated interactive network board, to receive location information of the designated interactive network board in response to the broadcast inquiry, and to establish communication with the designated interactive network board. The executable file is downloaded into RAM on the designated interactive network board through the local area network interface. A verifying step verifies a checksum value of the executable file against a checksum value in a checksum packet attached to the executable file. In the case that the verifying step is successfully completed, execution of the executable file may be commanded remotely, e.g., across the LAN interface.
