3.8 Load BIOS defaults
In rare cases, the system may not start because of certain BIOS settings. If that is the case, it is highly
recommended to first restore the BIOS factory settings before any debugging is done. This is achieved with
Load Optimized Defaults in the main setup menu. If you cannot reach the BIOS setup because of bad system
configuration, use the jumper near the power connector:
 Power off the board
 Set the 2.00 mm jumper Load BIOS defaults between pins 4 and 6
 Power on the board

Choose BIOS_DISABLE# to select the second BIOS (recovery).
