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 developer.intel.com/technology/efi.
