I usually suggest that you use the IPLDATA STATUS subcommand under IPCS to see the order of events during IPL, NIP, and MSI, and the duration of those events.

Has NIP / IPL changed in "recent" years? Was: Dr. Robert Rannie's diagram of NIP was Re: Diagram of MVS Control Blocks
Would this even remain accurate? It's a question I genuinely don't know the answer to: I suspect NIP has changed little. IPL has, I think, changed in detail (but I don't recall how).
