Chapter 3
Installing and Removing Options
You can enhance the performance of your computer by adding
optional equipment such as memory modules, option cards, or
a math coprocessor.
Memory modules-also called SIMMs (single inline memory
modules)-allow you to increase the amount of memory in
your computer.
An option card is a circuit board you install in your computer
to add a particular function, such as a modem or an additional
interface port.
The math coprocessor can be installed on the system board to
enhance numeric-intensive operations for software that
supports the coprocessor.
This chapter first describes how to remove your computer’s
cover to install options and how to replace the cover when you
are finished. It then describes the following:
Locating the internal components
Changing the jumper settings
Installing and removing memory modules (SIMMs)
Installing and removing option cards
