2.7 UEFI system settings
The Unified Extensible Firmware Interface (UEFI) is a pre-boot environment that provides an
interface between server firmware and operating system. It replaces BIOS as the software
that manages the interface between server firmware, operating system, and hardware
initialization, and eliminates the 16-bit, real-mode limitation that BIOS had.
Obtain more information about UEFI at the following website:

Many of the advanced technology options that are available in the eX5 systems are controlled
in the UEFI system settings. They affect processor and memory subsystem performance with
regard to the power consumption.
Access the UEFI page by pressing F1 during the system initialization process, as shown in
Figure 2-16.

Figure 2-17 on page 37 shows the UEFI System Configuration and Boot Management
window.
