drive or a mouse, you need to change the setting of a jumper
on the main system board. If you are removing a display
adapter card that is not an EGA or a VGA card, you need
to check the settings of jumpers J4 and J6. See “Changing
the Jumper Settings,” on page 5-6, for instructions.
5. Replace the cover. See “Replacing the Cover,” on page
5-34, for instructions.
Adding Memory Modules
Your computer comes with either 1MB or 2MB of memory
which is soldered directly onto the main system board. By
installing SIMMs (single inline memory modules), you can
increase the amount of memory in your computer up to 10MB
(for 1MB systems) or 14MB (for 2MB systems).
Caution
It is best to have your dealer install memory modules for you
because they can be damaged easily if installed incorrectly. If
you prefer, you can call install your own SIMMs by carefully
following the instructions in this section. However, you
could transmit an electrostatic discharge and damage your
components;
so read this entire section before you begin.
