Boot Mode Setting
The server supports Legacy mode and UEFI mode (default) as an OS Boot Mode. See the table below for
the Boot Mode and X2APIC setting for each Operating System. As the default settings at the factory, UEFI
mode is set as OS Boot mode and X2APIC is enabled. Refer to the User’s Guide and change the settings
before installing an Operating System requiring Legacy Mode.
