NAME

boot − bootstrap process

DESCRIPTION

The Series 700 and 800 bootstrap process involves the execution of three software components:

• pdc (see pdc(1M),

• isl (see isl(1M), and

• hpux (see hpux_800(1M)).

After the processor is RESET, pdc, the processor-dependent code (firmware), performs a self-test and initializes the processor.  It then loads and transfers control to isl, the operating-system-independent initial system loader. isl, in turn, loads and transfers control to the hpux utility, the HP-UX-specific bootstrap loader.  hpux then downloads the HP-UX kernel object file from an HP-UX file system and transfers control to the loaded kernel image.
