7.1.2 Unified Extendible Firmware Interface

The Unified Extensible Firmware Interface (UEFI) replaces BIOS in System x
and BladeCenter servers. It is the new interface between the operating system
and platform firmware. UEFI provides a modern, well-defined environment for
booting an operating system and running pre-boot applications.
For more information about UEFI, see this website:
http://www.uefi.org/home/
UEFI provides the following improvements over BIOS:
ASU now has complete coverage of system settings.
On rack mount servers, UEFI settings can be accessed out-of-band by ASU
and the IMM (not available on blades).
Adapter configuration can move into F1 setup; for example, iSCSI
configuration is now in F1 setup and consolidated into ASU.
Elimination of beep codes: All errors are displayed by using light path
diagnostics.
