Notes:
1. If no jumper is present, the server responds as if the pins are set to 1 and 2.
2. Changing the position of the UEFI boot recovery jumper from pins 1 and 2 to pins 2 and
3 before the server is turned on alters which flash ROM page is loaded. Do not change
the jumper pin position after the server is turned on. This can cause an unpredictable
problem.
