Table 9. NVMe Settings details 

Option

Description

NVMe Mode

This option sets the NVMe drive mode. If the system contains NVMe drives that you
want to configure in a RAID array, you must set both this field and the Embedded
SATA field on the SATA settings menu to RAID Mode. You may also need to change
the Boot Mode setting to UEFI. The option is set to 

Non-RAID

 mode by default.

BIOS NVMe Driver

Dell Qualified NVMe drives always use the UEFI NVMe driver built into the Dell BIOS.
When this option is set to 'All Drives', the BIOS driver will also be used with any NVMe
drives in the system that has not been qualified by Dell. The option is set to 

Dell

Qualified Drives

 by default.

NOTE:

 When this option is set to 'All Drives' and non-Dell qualified NVMe drives

are present, you have a configuration that has not been validated which may lead
to unexpected behavior.

Boot Settings

You can use the 

Boot Settings

 screen to set the boot mode to either 

BIOS

 or 

UEFI

. It also enables you to specify the boot

order.

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.

To view the 

Boot Settings

 screen, power on the system, press F2, and click 

System Setup Main Menu

 >
