Chapter 4 Installing Optional
Components
4.1 Installation Precautions
Before you install any system component, we recommend that you read the
following sections. These sections contain important ESD precautions, pre- and
post-installation instructions.
4.1.1 ESD Precautions
Electrostatic discharge (ESD) can damage your processor, disk drives, expansion
boards, and other components. Always observe the following precautions before
you install a system component:
1. Do not remove a component from its protective packaging until you are
ready to install it.
2. Wear a wrist grounding strap and attach it to a metal part of the system unit
before handling components. If a wrist strap is not available, maintain
contact with the system unit throughout any procedure requiring ESD
protection.

4.1.2 Preinstallation Instructions
Always observe the following before you install a system component:
1. Turn off the system power and all the peripherals connected to the unit before
opening it. To turn off the system:
i. Press the power button located on the front of the system unit for at least
four seconds. Quickly pressing the button puts the system in Suspend
mode only.
ii. Turn off the system main power switch located on the rear panel. If the
system main power switch is not available, unplug the system.
2. Open the system according to the instructions in section 4.2.1.
3. Follow the ESD precautions in section 4.1.1 before handling a system
component.
4. Remove any expansion boards or peripherals that block access to the DIMM
sockets or CPU socket.
5. See the following sections for specific instructions on the component you wish
to install.
Not turning off the system properly before
you start installing components may damage
your system.
Do not attempt the procedures described in
the following sections unless you are a
qualified service technician.

Chapter 4 - Installing Optional Components 4-3
4.1.3 Post-installation Instructions
Observe the following after installing a system component:
1. See to it that the components are installed according to the step-by-step
instructions in their respective sections.
2. Make sure you have set all the required jumpers. See section 2.3.2 for the
correct jumper settings.
3. Replace any expansion boards or peripherals that you removed earlier.
4. Replace the system cover.
5. Connect the necessary cables and turn on the system.
4.2 Removing and Replacing the Housing
Cover
Before you proceed, make sure that you have
turned off the system and all peripherals
connected to it. Read section 4.1.2 for
preinstallation instructions.
This section tells you how to open the housing cover when you need to install
additional components inside the system unit.
4.2.1 Removing the Housing Cover
1. Turn off power to the system unit and unplug all cables.
2. Place the system unit on a flat, steady surface.

3. Remove the four screws from the rear panel. Set the screws aside. You will
need them when replacing the housing cover.
Figure 4-1 Removing the Screws
4. Push the housing cover slightly backward as indicated in Figure 4-2.
5. Pull the housing cover upward and remove it from the chassis.

4.2.2 Replacing the Housing Cover
1. Replace the housing cover as shown in Figure 4-3.
Figure 4-3 Replacing the Housing Cover
2. Secure the housing cover with the necessary screws.

4.3 Installing and Removing Expansion
Boards
4.3.1 Installing a PCI Card
To install a PCI card:
1. Locate the PCI slot(s) on the system board.
2. Remove the bracket on the housing opposite to the empty PCI slot.
3. Insert a PCI card into the slot. Make sure that the card is properly seated.
4. Secure the card to the housing with a screw.
When you turn on the system, BIOS automatically detects and assigns resources
to the PCI devices.

Chapter 4 - Installing Optional Components 4-7
4.3.2 Installing ISA Cards
Both PnP and non-PnP ISA cards require specific IRQs. When installing ISA
cards, make sure that the IRQs required by these cards are not previously
assigned to PCI devices to avoid resource conflicts.
Follow these steps when installing ISA cards:
1. Remove all PnP cards installed in the system, if any.
2. Install non-PnP ISA cards.
3. Turn on the system.
4. Use Windows 95 or ICU to manually assign the appropriate IRQs to the
cards. This ensures that BIOS will not use the resources assigned to the non-
PnP ISA cards.
BIOS detects and configures only PnP cards.
6. Turn off the system.
7. Locate the expansion slots and install the PnP ISA and PCI cards.
8. Turn on the system. This time PnP BIOS automatically configures the PnP
ISA and PCI cards with the available resources.

4.4 Installing Additional Memory
The system memory is upgradable to a maximum of 256 MB via two 168-pin
DIMM sockets on board. These DIMM sockets accept DRAMs with 8-, 16-, 32-,
64-, and 128-MB capacities, 60 ns (nanoseconds) or less access time, and with
ECC. See Figure 2-1 for the location of the DIMM sockets. Section 4.4.1 tells how
to install DIMMs.
Table 4-1 lists possible memory configurations.

4.4.1 Installing a DIMM
1. Open the clips on the socket.
2. Align the DIMM with the socket.
3. Press the DIMM into the socket until the clips lock into the DIMM.
Figure 4-7 Installing a DIMM
The DIMM socket is slotted to ensure proper
installation. If you insert a DIMM but it does not fit
easily into the socket, you may have inserted it
incorrectly. Turn the DIMM around and try to insert
it again.
