3. Set up your controller to recognize the USB flash drive as your boot device. You can skip the following settings if the USB flash drive is already detected as shown in Figure 4 or Figure 5.
   • Navigate to Advanced/Boot >> LabVIEW RT Configuration >> LabVIEW RT Operating System and select NI Linux Real-Time. Press F10 to save changes and reboot if you changed the default setting. Press DEL to enter BIOS Setup Utility again. (Optional)
   • Navigate to Advanced >> USB Configuration >> Legacy USB Support and select Enabled. (Optional)
   • Navigate to Advanced >> USB Configuration >> Mass Storage Devices and select Auto. (Optional)
