Setting the Jumpers
If you need to change any jumper settings, follow these steps:
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.
4. 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.
Caution
Be careful not to bend the jumper pins or damage any
surrounding components on the main system board.
