NAME

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

SYNOPSIS

DESCRIPTION

       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 platform.

       supports the following options:

       Display the release and version numbers of the
			 utility.

       Boot the system in tunable maintenance mode, also known as "failsafe boot"
			 mode.	This option will disregard the tunable settings and module settings in the kernel  configuration,  and	boot  with
			 known good settings instead.

       Boot the system in VxVM maintenance mode, configure only the root volume,
			 and then enter single user mode.

       The following commands can be given interactively from the keyboard or provided in an efi(4) file.

       Load a kernel object file from an
			 HP-UX	file system and transfer control to the loaded image.  (Note, the operation is position-dependent).  Currently, is
			 limited to disk for booting.  file can be the name of a kernel object file or the name of a kernel  configuration  direc-
			 tory.

       The following commands can given interactively from the keyboard only after is launched.

       List the contents of
			 HP-UX directories in detail.

       List the contents of HP-UX directories.

       Display the contents of the
			 file.

       Change the contents of the
			 file to string.

   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  con-
			 figuration being booted.  value must be a decimal integer or a hexadecimal integer (with a prefix).

       can load only ELF object files.

   ll and ls Operations
       The  and  operations  list  the contents of the HP-UX directory.  In addition to filenames, displays size and date information when used on
       supported HP-UX filesystems.

       For VxVM disks, only boot volume information can be displayed.  To display boot volume information, either a relative path to or  an  abso-
       lute path can be used.

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

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

EXAMPLES

   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  executed  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 appli-
       cation.	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 file.

       Then it displays the progress of loading system- and kernel configuration-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 messages.

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