A math coprocessor speeds up the numeric calculations your
computer performs when using certain application software. If
you purchase a math coprocessor, it is a good idea to ask your
dealer to install it for you, because it can be damaged easily. If
you decide to install it yourself, follow the steps in this chapter.
This chapter also explains how to change the jumper settings
inside the computer. You may need to change jumper settings if
