ABSTRACT:
A method and system that enables a service processor to program a system resource. The service processor uses a JTAG Bus to request a system processor to enter into probe mode. Once in probe mode, the service processor sends a signal with instructions to the system processor. Upon execution of the instructions by the system processor, the executed instructions are forwarded to the appropriate address through a host bus and a controller. The service processor may forward instructions to any system resource through the system processor.
