Jumper Settings If you change your computer's configuration or need to alter the way it 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. The jumper settings in your computer are preset at the factory; however, you can control certain features by changing the standard settings as follows: tl Enable or disable the built-in mouse connector Cl Set your monitor type to monochrome or color Ll Change the amount of base memory tl Enable or disable the power-on password function U Enable or disable the built-in VGA display adapter tl Change the operation of the input/output ready signal. If you increase your computer's memory by installing memory modules, you must set a group of jumpers to indicate the amount of memory you now have. If you have the 25 MHz model and you had your 80486SX microprocessor chip replaced with a 80487SX chip, you must set jumpers JP1, JP2, and JP3 to indicate a new microprocessor is installed. (Because the 50 MHz model has a built-in math coprocessor, these jumpers are not used.) If you need to change any jumper settings, locate the jumpers on the main system board, shown on page 6-3. 6-4 Installing and Removing Options
