Resetting the System CMOS and BIOS Settings

    Last Modified: August 30, 2018

    The cRIO-904x BIOS configuration information is stored in a nonvolatile memory location that does not require a battery to preserve the settings. Additionally, the BIOS optimizes boot time by saving specific system information to memory backed up by a battery (CMOS).

    Complete the following steps to reset the CMOS and reset the BIOS settings to factory default values.

    1. Disconnect power from the cRIO-904x.
    2. Press the CMOS reset button and hold it for 1 second.
    3. Reconnect power to the cRIO-904x.
    The BIOS Reset Detected warning message appears onscreen.

    If the CMOS battery is dead, the CMOS reset button will not work.
