Extensible Firmware Interface
The Extensible Firmware Interface (EFI) is an OS and platform-independent boot and preboot
interface. EFI resides between the OS and platform firmware, allowing the OS to boot without
having details about the underlying hardware and firmware. EFI supports boot devices, uses a flat
memory model, and hides platform and firmware details from the OS.
NOTE:
EFI and Pre-OS System Environment (POSSE) are similar. EFI is an Intel specification,
whereas POSSE is the HP implementation that aids HP support.
EFI consolidates boot utilities similar to those found in PA-RISC based servers, such as the Boot
Console Handler (BCH), and platform firmware into a single platform firmware. EFI allows the
selection of any EFI OS loader from any boot medium that is supported by EFI boot services. An
EFI OS loader supports multiple options on the user interface.
EFI supports booting from media that contain an EFI OS loader or an EFI-defined server partition.
An EFI-defined system partition is required by EFI to boot from a block device.
