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 appropriate 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
you install certain types of options or if you want to change the
way your computer operates.
If you need to replace the battery for your computer’s real-time
clock and CMOS RAM, you can follow the instructions in this
chapter.
To change jumper settings, replace the battery, or install the
options mentioned above, you must remove the computer’s
cover and you may need to remove the subassembly. See
Chapter 3 for instructions. (You do not need to remove the
subassembly to install or remove option cards.)
