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 an additional
interface port.
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/25 or
486DX/33 system, you can install an OverDrive processor on
your system board to provide this increased performance.
(Alternatively, on the 4865X/25 system you can install a
487SX/25
chip to provide math coprocessor support.)
