Server Platform Utilities Extensible Firmware Interface (EFI) Shell The EFI Shell is an EFI application that allows other EFI applications to be launched, EFI device drivers to be loaded, and operating systems to be booted. The combination of the EFI firmware and the EFI Shell provides an environment that can be modified and adapted to many hardware configurations. The EFI shell provides a set of basic commands used to manage files and EFI NVRAM shell and boot variables. A list of these basic commands is shown in Table 10. Extensive information is available on the EFI website at http://developer.intel.com/technology/efi. For detailed information about the EFI Shell, its commands, and the ability to develop within the environment, see the EFI Developer's Guide at the EFI website. Other items that may be a great deal of help include the sample implementation and the EFI Application Toolkit. To obtain the sample implementation, click the "Tools" hyperlink at the left side of the EFI website screen. Click "Sample Implementation" to download the files to your hard drive. In addition to the standard shell commands available in the EFI Shell, the EFI environment allows you to create your own shell commands and EFI applications. To develop your own shell commands, download the EFI Application Toolkit from the "Tools" hyperlink on the EFI website. Table 10.
