Chapter 6 Installing and Removing Options You can enhance the performance of your computer by adding a variety of options, including the following: Q Option cards CI Memory modules Li 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. Installing and Removing Options 6-1
