NAME
       boot - bootstrap process

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

	      ·	 CMOS

	      ·	 option ROM

	      ·	 EFI

	      ·	 Boot Manager

	      ·	 (see hpux.efi(1M)).

       After the processor is reset, firmware initializes and tests processors
       and  platform.	During initialization, the firmware lets a user inter‐
       rupt and configure CMOS and option ROMs.	 It then transfers control  to
       EFI,  the Extensible Firmware Interface.	 EFI, in turn, initializes EFI
       boot and runtime services and launches the Boot Manager.	 The Boot Man‐
       ager,  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:

	      ·	 (see pdc(1M),

	      ·	 (see isl(1M), and

	      ·	 (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  con‐
       trol to the loaded kernel image.
