Table 19. SATA Settings details (continued) Option Description 1. You might also need to change the Boot Mode setting to UEFI. Otherwise, you should set the field to Non-RAID mode. 2. No ESXi and Ubuntu OS support under RAID mode. Security Freeze Lock Write Cache Port n Sends Security Freeze Lock command to the embedded SATA drives during POST. This option is applicable only for AHCI Mode. This option is set to Enabled by default. Enables or disables the command for the embedded SATA drives during POST. This option is set to Disabled by default. Sets the drive type of the selected device. For AHCI Mode or RAID Mode, BIOS support is always enabled. Table 20. Port n Options Model Drive Type Capacity Descriptions Specifies the drive model of the selected device. Specifies the type of drive attached to the SATA port. Specifies the total capacity of the drive. This field is undefined for removable media devices such as optical drives. NVMe Settings 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. 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 > System BIOS > Boot Settings. Table 21. Boot Settings details Option Boot Mode Description Enables you to set the boot mode of the system. If the operating system supports UEFI, you can set this option to UEFI. Setting this field to BIOS allows compatibility with nonUEFI operating systems. This option is set to UEFI by default. CAUTION: Switching the boot mode may prevent the system from booting if the operating system is not installed in the same boot mode. NOTE: Setting this field to UEFI disables the BIOS Boot Settings menu. Pre-operating system management applications 29
