Installing and Removing Options
You can enhance the performance of your computer by adding
a variety of options, including the following:
Option cards
Memory modules
An 80487SX microprocessor with built-in math coprocessor
(for the 25 MHz model).
An option card is a circuit board you install in your computer
to add a particular function. Most option cards contain a
device, such as a modem, or provide an interface, such as a
monitor connector. This chapter describes how to install option
cards and configure your computer for use with them.
Memory modules-also called SIMMs (single inline memory
modules)-allow you to increase the amount of memory in
your computer. This chapter describes the types and amounts
of SIMMs you can install on the memory card in your
computer. If you want to install memory modules, it is best to
ask your dealer to do it for you. You can, however, follow the
instructions in this chapter to install them yourself.
Note
It is best to add memory to your computer by installing
SIMMs rather than an additional memory card. Memory
modules are more efficient because the computer can access
memory installed on SIMMs faster than memory installed on
a card. If you do install an additional memory card, it will
slow the performance of your computer.
