20 Crisis Management
Modifying parameters in the BIOS Setup implies the risk of leaving your system in a unbootable state. In
case this happens two jumper exists to reset the settings to 'Fail-Safe values'.
In case no battery is connected then follow these five steps:
❶ Power down the board
❷ Remove the tagged jumper JP9 (see the picture)
❸ Power up the board and enter the BIOS Setup
❹ Before saving your new settings with 'Save & Exit' put the jumper back
❺ The board should be functional now
In case there is a backup battery for the real time clock:
❶ Power down the board
❷ Switch the second jumper JP8 as depicted and wait for 3 seconds
❸ Put the jumper back as it was before
Then continue with the steps from the no battery case.
