HP-UX System Administrator's Guide: Routine Management Tasks

Procedure 2-2 Booting from the EFI Shell
1. Access the EFI Shell.
From the system console, use the up/down arrow keys to select the “EFI Shell”
entry from the EFI Boot Manager menu to access the shell.
2. Access the EFI System Partition for the HP-UX boot device.
Use the map EFI Shell command to list the file systems (fs0, fs1, and so on) that
are known and have been mapped.
To select a file system to use, enter its mapped name followed by a colon (:). For
example, to operate with the boot device that is mapped as fs0, enter fs0: at the
EFI Shell prompt. When you hit Enter to complete the command the shell prompt
will change to reflect your device selection: (fs0:\>)
If the map command shows a lot of devices you can use the -b option to make it
show the output one screen at a time.
3. Enter HPUX at the EFI Shell command prompt to launch the HPUX.EFI loader
from the currently selected boot device.
If needed, you can specify the loader’s full path by entering \EFI\HPUX\HPUX at
the EFI Shell command prompt.
4. Allow the HPUX.EFI loader to proceed with the boot command specified in the
AUTO file, or manually specify the boot command.
By default, the HPUX.EFI loader boots using the loader commands found in the
\EFI\HPUX\AUTO file on the EFI System Partition of the selected boot device. The
AUTO file typically contains the boot vmunix command.
To interact with the HPUX.EFI loader, interrupt the boot process (for example,
type a space) within the time-out period provided by the loader. To exit the loader
use the exit command; this will take you back to EFI.
Adjusting the Autoboot Delay
By default, the automatic boot delay is set to 10 seconds. You can change this value:
