J1 Jumper

The J1 jumper is used to tell the Mellanox chip that there is a Flash ROM present in the system. If the jumper is closed (enabled) it means that no Flash ROM is present, while open (disabled) means that a Flash ROM is present.

J2 Jumper

The J2 jumper is used for engineer debugging only.
