Using the EFI Boot Manager
The EFI (Extensible Firmware Interface) Boot Manager allows you to control the server's
booting environment. From the Boot Manager, you can choose to invoke the Extensible
Firmware Interface (EFI) Shell or to go to the Boot Option Maintenance Menu.
To enter the EFI Boot Manager:
1. From the PAM Tree, click Domain Manager → Power ON to power up the required
domain.
2. From the keyboard, press the Control key twice to display the KVM Switch Command
Menu.
3. Select the required system channel port with the ↑↓ keys, according to configuration. See
KVM port configuration, in the User's Guide.
4. Press Enter to activate the required system channel and exit the Command Mode.
Note:
The system automatically boots on the first option in the list without user intervention after
a timeout. To modify the timeout, use Set Auto Boot Timeout in the Boot Option
Maintenance Menu.
5. From the Boot Manager Menu, select the EFI Shell option with the ↑↓ keys and press
Enter.
EFI Boot Manager Options
EFI Shell
A simple, interactive environment that allows EFI device drivers to be loaded, EFI applications
to be launched, and operating systems to be booted. The EFI shell also provides a set of
basic commands used to manage files and the system environment variables. For more
information on the EFI Shell, refer to Using the EFI Shell on page 5-9.
Boot Options
Files that you include as boot options. You add and delete boot options by using the Boot
Maintenance Menu. Each boot option specifies an EFI executable with possible options. For
information on the Boot Maintenance Menu options, refer to Table 30.
Boot Option Maintenance Menu
The EFI Boot Maintenance Manager allows the user to add boot options, delete boot options,
launch an EFI application, and set the auto boot time out value.
If there are no boot options in the system (and no integrated shell), the Boot Maintenance
Menu is presented. If boot options are available, then the set of available boot options is
displayed, and the user can select one or choose to go to the Boot Maintenance Menu.
If the time out period is not zero, then the system will auto boot the first boot selection after
the time out has expired. If the time out period is zero, then the EFI Boot Manager will wait
for the user to select an option. Table 30 describes each menu item in the Boot Maintenance
Menu.
Note:
You can use the → ← ↑↓ keys to scroll through the Boot Maintenance Menu.
