ABSTRACT:
A computer system includes a first processor with main memory, an input/output processor with associated memory and an archival memory. Prior to reloading a new operating system from archival memory into the main memory, information such as timer information is stored in the input/output memory. The input/output memory continues to update the timer information until the second operating system is bootstrap loaded into the main memory. The timer and other information may then be returned to the first processor and main memory for use by the second operating system.
