Installing and Removing Options
You can enhance the performance of your computer by adding
optional equipment such as memory modules, option cards, or
an Intel OverDrive processor.
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 a network
interface.
An OverDrive processor is a CPU chip which doubles the
internal processing speed of the microprocessor and includes a
built-in math coprocessor. If you have the 486SX/33 model, you
can replace the CPU chip on your system board with an
OverDrive processor to provide this increased performance.
(Alternatively, you can replace the 486SX/33 CPU chip with a
487SX/33 chip, to provide math coprocessor support.)
