Introduction
The EFI (Extensible Firmware Interface) Shell is an EFI application that lets other EFI
applications be launched, EFI device drivers be loaded, and operating systems be booted.
The EFI Shell provides an interface between operating systems and platform firmware. The
combination of the EFI Shell and EFI firmware provides an environment that can be
adapted to many hardware configurations.
The help command provides information about all the commands (help -b) or specific
commands (help <command>).
For detailed information about the EFI Shell, its commands, and help in developing
applications within the EFI environment, refer to Intel’s EFI Developer’s Guide at
