Using EFI |

The Intel Extensible Firmware Interface (EFI) specification defines a model for the interface between the OS, the firmware, and the hardware. EFI serves the same purpose on Itanium-based computers as the BIOS on x86-based computers. EFI provides a standard environment for running pre-boot applications and for booting the OS. HP Integrity servers use EFI to initialize the platform firmware and load the OS. After the system is initialized, EFI provides two interfaces with which you can interact, as described in the following sections. First displayed when you power on the server, the EFI Boot Manager provides a menu-based interface (Figure 4-1 is an example) with options for booting the OS, loading EFI applications, configuring the server, and performing other pre-boot operations. Available as a selection from the EFI Boot Manager, the EFI Shell provides a command-line interface from which you can get information about the system, install an operating system, boot the operating system, execute batch scripts, launch EFI applications, load EFI drivers, and manage files and system variables.
