    I had some problems with this devices. Expecially to use for headless server.
    After current interruption they didn’t boot if an operator didn’t press F1 (or F2 to enter bios).
    So every power problem, obliged to connect a keyboard and blindly press F1 to make it boot.
    After this operation it boot every time correctly. But another power interruption obliged to press F1.
