3. Remove the retaining screw from the top of the metal
option slot cover: hold on to the screw as you remove it so it
doesn’t fall into the computer. 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.
4. Unpack the option card and adjust any switches or jumpers
on it, if necessary. (Check the option card instructions.)
When you handle the card, be careful not to touch any of
the components on the circuit board, especially the gold-
edged connector pins. If you need to set it down before you
install it, place it gently on top of its original packing
material with the component side facing up. Keep the
packing materials in case you remove the card later.
