    The cRIO-904x POST displays warning messages for specific issues onscreen. You can use MAX to enable Console Out to send these warning messages through the RS-232 serial port.

    The POST can display the following warning messages:

    • BIOS Reset Detected—This warning is displayed when the CMOS Reset button has been pushed. This warning indicates that the BIOS settings have the default values.
    • CMOS Battery Is Dead—This warning is displayed when the CMOS battery is dead and must be replaced. The BIOS settings are preserved even when the CMOS battery is dead, but the system will boot very slowly because the BIOS cannot optimize boot time by saving specific system information to CMOS.
