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 or the gold-edged
connectors. 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.
Hold the card along the top corners and guide it into the
connector, as shown below. (If you're installing a
full-length card, insert the front edge of the card into the
corresponding guide inside the computer's front panel.)
