A method and system of determining by a first program an attribute of a first functional unit by referencing a virtual memory address (the first functional unit comprising a first processor and a random access memory (RAM) coupled to the first processor in a computer system, and the first program executing in the first functional unit), determining by a second program an attribute of a second functional unit by referencing the virtual memory address (the second functional unit comprising a second processor and a RAM coupled to the second processor in the computer system, and the second program executing in the second functional unit), wherein referencing the virtual memory address by the first program provides a pointer to an attribute stored in the RAM of the first functional units, and wherein referencing the virtual memory address by the second program provides a pointer to an attribute stored in the RAM of the second functional unit.

Method and system of determining attributes of a functional unit in a multiple processor computer system

A method and apparatus of remotely booting a target computer system from a host computer system over a communication medium comprises exchanging messages between the host and target computer systems. The host computer system controls the remote booting and communicates the initial booting request to the target computer system. The target computer system may respond by communicating to the host computer system whether it will boot. During booting, the target computer system transitions between a polling or stopped state and an interrupt-driven state by transitioning both a target operating system and network hardware in the target computer system between the polling and interrupt-driven states.

A method of remote debugging comprises a first computer system that communicates with a second computer using a network connection. The first computer system controls the remote debugging and comprises a first operating system. The second computer system comprises a second operating system and software being tested. User input, in the form of debug commands, is received using a remote debugger in the first computer system to control the remote debugging session. The remote debugger translates a debug command into messages that are sent from the first computer system to the second computer system. The messages correspond to tasks that the target computer system performs to complete the debug command. During debugging, the target computer system transitions between polling or stopped mode and interrupt-driven mode by transitioning both the target operating system and network hardware in the target computer system that interfaces with the network.
