Setting the Jumpers
Jumpers are used on this mainboard to select various settings and features. A 2-pin
jumper has two settings: Open and Short (or Closed). The jumper is closed by
placing the Jumper Cap across the two pins, thereby connecting them. 3-pin
jumpers can be set to pins 1-2 or 2-3 connected. Pin-1 is labeled on the circuit
board.
