Abstract
A method, system, and apparatus of recording information generated by a data processing system prior to completion enablement of programmed input/output services for the data processing system is provided. In one embodiment, a service processor receives an attention interrupt from a host processor. The service processor then stops the operation of all host processors in the data processing system. The service processor then reads the information, such as a system checkpoint, from a buffer within the host processor's system memory and writes the information into a non-volatile random access memory as well as displays the information to a user via a video display. The service processor then restarts the host processors.
