Service Manual

● UEFI: The Unified Extensible Firmware Interface (UEFI) is a new interface between operating systems and platform
firmware. The interface consists of data tables with platform related information, boot and runtime service calls that are
available to the operating system and its loader. The following benefits are available when the Boot Mode is set to UEFI:
○ Support for drive partitions larger than 2 TB.
○ Enhanced security (e.g., UEFI Secure Boot).
○ Faster boot time.
● BIOS: The BIOS Boot Mode is the legacy boot mode. It is maintained for backward compatibility.
To view the Boot Settings screen, power on the system, press F2, and click System Setup Main Menu > System BIOS >
Boot Settings.
