Changing the Jumper Settings
If you change your computer’s configuration or need to alter the way your computer operates, you may need to change a jumper setting inside the computer.
A jumper is a small electrical connector that controls one of the computer’s functions. A jumper’s setting is determined by where it is placed: either over pin A and the middle pin (position A) or over pin B and the middle pin (position B), as shown below:
position A | position B |
