The Extensible Firmware Interface (EFI) Shell
The EFI Shell is an EFI application that allows other EFI Applications to be
launched. The combination of the EFI firmware and the EFI Shell provide an
environment that can be modified to easily adapt to many different hardware
configurations. The EFI shell is a simple, interactive environment that allows EFI
device drivers to be loaded, EFI applications to be launched, and operating
systems to be booted. In addition, the shell also provides a set of basic commands
used to manage files and the system environment variables.
After booting the server to the EFI Shell, you have all its commands available to
you. Table 10-2 provides a brief description of the commands.
In addition to shell commands made available to you, the EFI environment allows
you to create your own shell commands and EFI applications. For detailed
information about the EFI Shell, its commands, and the ability to develop within
the environment, refer to the EFI Developer's Guide. To find this guide, you must
download the "EFI sample implementation source code" from the sample
implementation download area of the Extensible Firmware Interface Web Site.
Go to the following URL and click on the "EFI sample implementation source
code". Once you download the sample, locate the Microsoft Word file named
"Efi_dg.doc" in the "Notes" folder.

Description
Allows you to define the value in seconds that pass
before the system automatically boots without user
intervention. Setting this value to zero disables the
timeout feature.
Allows you to switch the COM2 from the system port
(used for redirection) and gives control of the COM2
port to EMP (Emergency Management Port).
Performs a platform-specific cold reset of the system. A
cold reset traditionally means a full platform reset.
Returns control to the EFI Boot Manager main menu.
This will display the active boot devices, including a
possible integrated shell (if the implementation is so
constructed).
