Using The Extensible Firmware Interface (Efi) Shell - IBM eServer 380 xSeries User Reference Manual

Using the Extensible Firmware Interface (EFI) shell

Use the EFI shell to load device drivers, start EFI applications, and start (boot) the
network operating system. In addition, the EFI shell also provides a set of basic
commands to manage files and system environment variables.
In addition, with the EFI shell, you can create your own EFI shell commands and EFI
applications. For detailed information about the EFI shell, its commands, and the
ability to develop applications, refer to the EFI Developer's Guide. Find the guide at
the following World Wide Web address:
http://developer.intel.com/technology/efi/downsource.htm.
Click EFI sample implementation source code and select the Microsoft
Efi_dg.doc in the Notes folder.

Description
Enables you to display the list of available console output
devices, as contained in the ConOutDev list. You can select or
deselect additional output consoles from this menu. Note: The
Boot Maintenance Manager performs logic checking to ensure
that you choose a legal ensemble of devices. For example, the
manager does not allow you to choose two different messaging
devices, such as PC-ANSI and VT-100, to be active consoles
on a given UART.
Enables you to display the list of available console input
devices, as contained in the ConInDev list and the subset
detailed in the ConIn variable.
Enables you to display the list of available error devices as
contained in the ErrOutDev list and the subset detailed in the
ErrOut variable.
Note: The active error devices are essentially a type of
console output device whose only traffic includes error
messaging.
Enables you to perform a platform-specific cold reset of the
system.
Note: A cold reset typically 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
EFI shell (if the implementation is so constructed).
