Configuring System Boot Options
This section discusses the system boot options you can configure on the server, including the
boot options list and the autoboot setting for the server.
• Boot Options List The boot options list is a list of loadable items available for you to select
from the EFI Boot Manager Menu. Ordinarily the boot options list includes the EFI Shell
and one or more operating system loaders.
To manage the boot options list for each system, use the EFI Shell, the EFI Boot Configuration
Menu, or operating system utilities.
At the EFI Shell, the bcfg command supports listing and managing the boot options list for
all operating systems.
The EFI Boot Configuration Menu includes the Add a Boot Option, Delete Boot Option(s),
and Change Boot Order menu items. Use this menu if you must add an EFI Shell entry to
the boot options list.
Operating system utilities for managing the boot options list include the HP-UX setboot
command.
For information, see the following sections:
— To set HP-UX boot options, see “Adding HP-UX to the Boot Options List” (page 99).
— To set Linux boot options, see “Adding Linux to the Boot Options List” (page 103).
• Autoboot Setting At startup, the autoboot setting determines whether a system
automatically loads the first item in the boot options list, or remains at the EFI Boot Manager
