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.
NOTE:
You must use only the UEFI boot mode in order to boot from NVMe drives.
•
BIOS
: The
BIOS Boot Mode
is the legacy boot mode. It is maintained for backward compatibility.
