Abstract
In response to the start of an initialization sequence at a service processor, if power to a main processor was interrupted at a most-recent time that an operating system executed on the main processor, power to the main processor is turned on, the operating system is started executing on the main processor, data from the non-volatile memory of the service processor is provided to the operating system, and the service processor is reset, which restarts the initialization sequence. If the power to the main processor was not interrupted at the most-recent time that the operating system executed on the main processor, and if the operating system is currently executing on the main processor, a monitoring function is started in the service processor, which monitors for errors at a computer system.
