1.
Refer to the illustration on page 2-3 to locate the jumpers on
the main system board.
2.
If there are any option cards installed in your computer, you
need to remove them to access the jumpers. See page 2-18
for instructions.
3.
If the option card connector board is in your way, you can
remove it. See page 2-19 for instructions.

A jumper’s setting is determined by where the jumper is
placed on the pins. It connects either pin A and the middle
pin (position A) or pin B and the middle pin (position B), as
shown below.

To move a jumper from one position to the other, use
needle-nose pliers or tweezers to pull it off its pins and
gently move it to the desired position.
