Resetting the System CMOS and BIOS Settings

The cRIO-903x 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-903x.
  2. Press the CMOS reset button and hold it for 1 second.
  3. Reconnect power to the cRIO-903x.
The BIOS Reset Detected warning message appears onscreen.
Note If the CMOS battery is dead, the CMOS reset button will not work.
