Installing an Option Card
Follow these steps to install an option card
1. If you are installing an option card that controls a mouse, you
may need to change the setting of jumper JP3 or JP4 before
you install the card. If you install a display adapter card,
you may need to change the settings of jumpers JP5 and
JP7. See page 3-4 for instructions.
2. Remove the retaining screw from the top of the metal option
slot cover; hold on to the screw so it doesn’t fall into the
computer. Then lift out the slot cover.
Keep the screw to secure the option card to the computer.
Store the slot cover in a safe place in case you remove the
option card later.
