Option
Parameter Description
Boot Mode
[UEFI Mode]
Legacy BIOS Mode
Use this option to select the boot mode of the
system. Selecting UEFI Mode configures the
system to boot Unified Extensible Firmware
Interface (UEFI) compatible operating systems.
Selecting Legacy BIOS Mode configures the
system to boot traditional operating systems in
Legacy BIOS compatibility mode. The operating
system can only boot in the mode in which it is
installed. The following options require booting in
UEFI Mode: Secure Boot, IPv6 PXE Boot, boot >
2.2 TB Disks in AHCI SATA Mode, and Smart
Array SW RAID.
UEFI Optimized Boot
[Enabled]
Disabled
When enabled, the system BIOS boots using
native UEFI graphics drivers. When disabled, the
system BIOS boots using INT10 legacy video
support. You cannot disable this option if Secure
Boot is enabled. You can only configure this
option if Boot Mode is configured to UEFI Mode.
Set this option to enabled for compatibility with
VMWare ESXi operating systems on a system
configured for UEFI Mode.
Boot Order Policy
[Retry Boot Order Indefinitely]
Attempt Boot Order Once
Reset After Failed Boot Attempt
Use this option to configure how the system
attempts to boot devices per the Boot Order list
when no bootable device is found. If configured to
'Retry Boot Order Indefinitely,' the system
continuously attempts to process the Boot Order
list until a bootable device is found. If configured
to 'Attempt Boot Order Once,' the system
attempts to process all items in the Boot Order
list once, and if unsuccessful, waits for user input
to proceed. If configured for 'Reset After Failed
Boot Attempt,' the system attempts to process all
items in the Boot Order list once, and then
reboots the system.
