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 Reset 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
boot_manager is launched. The EFI
boot_manager gives the user the option to
automatically start any EFI application. After
hpux.efi is launched by the EFI boot_manager
,it
looks for an
AUTO file and uses its content for the boot string. Then it gives the user the option to override
the autoboot sequence by pressing any key:
*** HP-UX Boot Loader for IA-64 ***
*** Version #.# ***
*** Type ’help’ for help ***
Press Any Key to interrupt Autoboot
AUTO ==> boot vmunix -is
Seconds left till autoboot - 10
If hpux.efi does not detect a key press, it initiates the autoboot sequence using the AUTO
string.
hpux.efi displays messages similar to the following on the console:
AUTOBOOTING...
AUTO BOOT> boot vmunix -is
If hpux.efi successfully locates the kernel object file, it displays the progress of loading each sections
and the symbol table of the object file.
loading section 0
....................
loading section 1
......
Loading symbol table. Num of Sec Header(79)
Then it displays the progress of loading system- and kernel configuration-specific directories.
Loading System Directory(boot.sys) to MFS
....
Loading Kernel Boot Directory(bootfs) to MFS
......
Finally, boot displays the complete path to the kernel object file loaded and the TEXT
size, DATA size,
and
BSS size of the load image before control is passed to the image.
Launching /stand/vmunix...
SIZE: Text:16308K + Data:1268K + BSS:2004K = Total:19581K
The loaded image then displays numerous configuration and status messages.
Interactive Boot
To use hpux.efi interactively, the user must interrupt the autoboot sequence by pressing a key or
removing the AUTO file. Then hpux.efi interactively prompts for commands.
