2. Cover the option slot opening with the original metal slot
cover and secure it with the retaining screw.
3. If you are removing an option card that controls a mouse,
you may need to change the setting of jumper JP3 or JP4 on
the main system board. If you are removing a display
adapter card, you may need to change the settings of
jumpers JP5 and JP7. See page 3-4 for instructions.
4. If you made any system configuration changes when you
installed the card, change them again as necessary after you
remove the card and replace the computer’s cover.
Memory Modules (SIMMs)
Your computer comes with 4MB of memory soldered onto the
main system board. By installing memory modules-also called
SIMMs (single inline memory modules)--you can increase the
amount of memory in your computer up to 128MB.
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 to install them yourself, carefully
follow all the instructions in this section.
Before you install SIMMs, check the following guidelines to
ensure that they will work properly:
Use only 36-bit, fast-page mode SIMM
S
that operate at an
access speed of 70ns (nanoseconds) or faster. Be sure all the
SIMMs operate at the same speed.
Use the correct SIMM configuration to add the amount of
memory you want. See the table on the next page.
