Bootloader → Boot loader – Correct spelling uses a space PhotographyEdits (talk) 20:15, 15 August 2021 (UTC)[reply]

Bootloader is the common spelling. A google search for "bootloader" -"boot loader" returns almost twice as many results as "boot loader" -"bootloader". See also Google ngrams, where "bootloader" has been the predominant spelling in books since around 2014. --Ahecht (TALK

Classification of IPL loader for OS/360 and successors?

In an IPL of OS/360 and successors, cylinder 0 track 0 record 1 contains a 24-byte record, cylinder 0 track 0 record 2 contains the bootstrap loader and cylinder 0 track 0 record 3 contains the IPL loader constructed by a utility program from the IBM supplied IPLTEXT. The 24-byte record contains the initial PSW for the IPL loader and 2 channel Command Words (CCWs), the second of which is a Transfer In Channel (TIC) CCW to the bootstrap loader. The IPL loader locates the SYS1.NUCLEUS load library, loads the IEANUC0x member selected by the operator and transfers control to the Nucleus Initialization Program (NIP).

The IPL loader does not support chain loading, use of an alternate library or loading any member other than IEANUC0x.

So what is the taxomomy of those three records and, in particular, is the IPL loader stage 1 or stage 2? Shmuel (Seymour J.) Metz Username:Chatul (talk) 18:50, 16 December 2022 (UTC)[reply]

Sequence of events

{{ping|Soumyapatra13]] The system reset and Power On Self Test (POST) run before the boot loader. The boot loader and operating system handle the transition from the system reset stage, not from the power off stage. It is common to reboot (reIPL) multiple times without powering off, especially in the mainframe world. -- Shmuel (Seymour J.) Metz Username:Chatul (talk) 15:40, 10 November 2024 (UTC) IPL[reply]

Thanks, but isn't the same (erroneous) info present in the reinstated revision? @Chatul: Soumyapatra13 (talk) 16:36, 10 November 2024 (UTC)[reply]
