Abstract: A method for remote access to a firmware developer user interface in a multi-nodal computer system comprises registering a manageability subsystem with a server; booting the multi-nodal computer system; entering, by a truant cell of the multi-nodal computer system, into a remote developer user interface mode; writing, by the truant cell, a remote developer user interface initialization sequence to shared memory of the manageability subsystem; acknowledging, by a processor of the manageability subsystem, acceptance of the initialization upon the registering; sending an open session request to the server; and spawning an interactive developer user interface terminal session on the server.

Abstract: A method for providing a firmware developer user interface in a multi-nodal computer system comprises invoking a firmware developer user interface during boot of a multi-nodal computer system, dumping a process state for the boot to a console, handing-off flow control of the boot to the developer user interface and accepting at least one command to firmware of the multi-nodal computer system via the console and the developer user interface.

Abstract: A method for providing a firmware developer user interface in a multi-nodal computer system comprises polling for a break command during boot of a multi-nodal computer system and invoking a firmware developer user interface when the break command is encountered.
