In the controller System Controls page, the System Configuration menu, there has a feature called 'Host Interface Mode'. Set this option to “NVMe Mode”.
Note: Motherboard should set to "UEFI Boot" or "Dual Boot" in NVMe Mode so you can get to the McBIOS setup utility through "UEFI Areca OS" from the Boot List?
