Tips and Features for Administrators
Using the EFI Shell
The EFI (Extensible Firmware Interface) Shell is a simple, interactive user interface that
allows EFI device drivers to be loaded, EFI applications to be launched, and operating
systems to be booted. In addition, the Shell provides a set of basic commands used to
manage files and the system environment variables.
Warning:
The EFI shell can only manage QWERTY keyboards. If you have an AZERTY
keyboard, please refer to the AZERTY/QWERTY keyboard lookup table on page xvii.
Note:
The EFI Shell supports command line interface and batch scripting.
Entering the EFI Shell
To enter the EFI Shell:
1. From the PAM Tree, click Domain Manager Power ON to power up the required
domain.
2. Press the Control key twice to access the Command Menu.
3. Select the required port with the ↑↓ keys, according to configuration.

4. Press Enter to activate the required system channel and exit the Command Mode. After
a few seconds, the Boot Manager menu is displayed.
5. From the Boot Manager Menu, select the EFI Shell option with the ↑↓ keys and press
Enter.
When the EFI Shell is invoked, it first looks for commands in the file startup.nsh
on the
execution path defined by the environment. There is no requirement for a startup file to
exist. Once the startup file commands are completed, the Shell looks for commands from
console input device.
Note:
The system automatically boots on the first option in the list without user intervention after a
timeout. To modify timeout, use Set Auto Boot Timeout in the Boot Option Maintenance
Menu.
