A method to reduce and thereby improve the initial program load time of a computing apparatus operating system and thus provides for near instantaneous user interaction. When practicing the instant invention, a computing apparatus operating system or application processing component is loaded neither sequentially nor completely, but rather on an as required basis. The invention's “required only” loading of processing components persist through subsequent operation and shut down of the computing apparatus with each loaded task creating a checkpoint record of processing modifications to non-volatile memory. Such checkpointing allows shut down processing of the apparatus to consist of merely flushing memory buffers in the apparatus checkpointed non-volatile memory of the apparatus to permanent storage and powering off of the apparatus, with subsequent initial program load (IPL) sequencing referencing the checkpointed records to minimize future system initialization elapsed time. |
