Option Description
For AHCI Mode or RAID Mode, BIOS support is always enabled.
Option Description
Model Specifies the drive model of the selected device.
Drive Type Specifies the type of drive attached to the SATA port.
Capacity Specifies the total capacity of the drive. This field is undefined for removable media
devices such as optical drives.
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.
Viewing Boot Settings
To view the Boot Settings screen, perform the following steps:
Steps
1. Power on, or restart your system.
2. Press F2 immediately after you see the following message:
F2 = System Setup
NOTE:
If your operating system begins to load before you press F2, wait for the system to finish booting, and then
restart your system and try again.
3. On the System Setup Main Menu screen, click System BIOS.
4. On the System BIOS screen, click Boot Settings.
Choosing system boot mode
System Setup enables you to specify one of the following boot modes for installing your operating system:
● BIOS boot mode (the default) is the standard BIOS-level boot interface.
● UEFI boot mode (the default), is an enhanced 64-bit boot interface. If you have configured your system to boot to UEFI
mode, it replaces the system BIOS.
1. From the System Setup Main Menu, click Boot Settings, and select Boot Mode.
2. Select the UEFI boot mode you want the system to boot into.
CAUTION:
Switching the boot mode may prevent the system from booting if the operating system is not
installed in the same boot mode.
3. After the system boots in the specified boot mode, proceed to install your operating system from that mode.
NOTE:
Operating systems must be UEFI-compatible to be installed from the UEFI boot mode. DOS and 32-bit operating
systems do not support UEFI and can only be installed from the BIOS boot mode.
