       hpux.efi - HP-UX bootstrap for Itanium-based systems

       is  the	HP-UX-specific	operating system loader utility for bootstrap.
       It is a native efi(4) application that can be run on the	 Itanium-based

       Boot the system in VxVM maintenance mode, configure only the root  vol‐

   boot Operation
       The operation loads an ELF kernel object file from supported HP-UX file
       system (HFS, VxFS).  It then transfers control to the loaded image.

       In addition to the kernel object file, also  loads  persistent  system-
       specific	 files	from  the  directory and kernel configuration-specific
       files from the directory during operation.

       always assumes (the boot directory)  as	the  current  directory.   For
       example, would actually yield:

       Along with this information, gives the sizes of the and segments before
       transferring control to it.

       The operation accepts several options.  Note that options be  specified
       positionally  as	 shown	in the syntax statement in the Options for the
       operations are as follows:

       Set the initial	 run-level for when booting  the  system.   This  run-
			 level	overrides  any run-level specified in an entry
			 in See init(1M) and inittab(4).

       variable=value	 Set the specified variable to	the  specified	value.
			 (No whitespace is allowed.)

			 If  variable is a kernel tunable parameter, this sets
			 the value of that tunable, overriding	the  value  in
			 the kernel configuration being booted.	 value must be
			 a decimal integer or a hexadecimal  integer  (with  a

       can load only ELF object files.

   ll and ls Operations
       The  and operations list the contents of the HP-UX directory.  In addi‐
       tion to filenames, displays size and date information when used on sup‐
       ported HP-UX filesystems.

       For VxVM disks, only boot volume information can be displayed.  To dis‐
       play boot volume information, either a relative path to or an  absolute
       path can be used.

   setauto Operation
       The  operation  overwrites  the	contents  of the file, with the string

   showauto Operation
       The operation displays the contents of the file, See in the section.

   Automatic Boot
       This is an overview of HP-UX automatic boot processes on	 Itanium-based
       systems.	  When	power is applied to the HP-UX system processor, or the
       system button is pressed, Itanium-based system firmware	code  is  exe‐
       cuted  to  verify hardware and general system integrity (see boot(1M)).
       After initializing the hardware, the EFI is launched.   The  EFI	 gives
       the  user the option to automatically start any EFI application.	 After
       is launched by the EFI it looks for an file and uses  its  content  for
       the  boot  string.   Then  it gives the user the option to override the
       sequence by pressing any key:

       If does not detect a key press, it initiates  the  sequence  using  the
       string.	displays messages similar to the following on the console:

       If  successfully	 locates  the  kernel  object  file,  it  displays the
       progress of loading each sections and the symbol table  of  the	object

       Then  it displays the progress of loading system- and kernel configura‐
       tion-specific directories.

       Finally, displays the complete path to the kernel  object  file	loaded
       and the size, size, and size of the load image before control is passed
       to the image.

       The loaded image then displays numerous configuration and  status  mes‐

   Interactive Boot
       To  use interactively, the user must interrupt the autoboot sequence by
       pressing a key or removing the file.  Then  interactively  prompts  for

       boot(1M), hpux(1M), init(1M), efi(4), inittab(4).
