The EFI Boot Manager allows you to control the server's booting environment.
Depending on how you have configured the boot options, after the server is powered
up the Boot Manager presents you with different ways to bring up the system. For
example, you can boot to the EFI Shell, to an operating system located on the network
or residing on media in the server, or the Boot Maintenance Menu.
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
"The Extensible Firmware Interface (EFI) Shell" on page 89.
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 2 on page 87.
Boot Maintenance Menu
A menu of items allowing you configure boot options and configure other
boot environment variables. The following table describes each menu item in
the Boot Maintenance Menu.
