Definition
Power On
POST (extent will depend on diag-switch? and diag-level)
Boot system (depending on auto-boot? variable)
bootblk: The OBP (Open Boot PROM) program loads the bootblk primary boot program from the boot-device
ufsboot: The secondary boot program, /platform/`arch -k`/ufsboot is run. This program loads the kernel core image files.
kernel: The kernel is loaded and run (e.g. /platform/`arch -k`/kernel/unix & /kernel/genunix)
kernel initialized: The kernel creates PID 0 ( sched). The sched process is sometimes called the "swapper."
init: The kernel starts PID 1 (init). |
