NAME

       boot - bootstrap process

DESCRIPTION

   Itanium-based System Hardware
       An system's bootstrap process involves the execution of four software components:

	      o  CMOS

	      o  option ROM

	      o  EFI

	      o  Boot Manager

	      o  (see hpux.efi(1M)).

       After  the  processor  is  reset,  firmware initializes and tests processors and platform.  During initialization, the firmware lets a user
       interrupt and configure CMOS and option ROMs.  It then transfers control to EFI, the Extensible Firmware Interface.  EFI, in turn, initial-
       izes  EFI  boot	and  runtime services and launches the Boot Manager.  The Boot Manager, which allows loading of EFI application or drivers
       from EFI defined file system, loads and transfers control to the HP-UX-specific bootstrap loader.  then loads the HP-UX kernel object  file
       from the HP-UX file system to memory and transfers control to the loaded kernel image.

   PA-RISC Hardware
       The PA-RSIC bootstrap process involves the execution of three software components:

	      o  (see pdc(1M),

	      o  (see isl(1M), and

	      o  (see hpux(1M).

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