3. INSTALLATION
Precaution Before Start
Static Electricity Damage:
Static electricity can easily damage your motherboard.
Observing a few basic precautions will help safeguard
against damage that could result in expensive repairs.
Please read the following before you begin installation.
1. Keep the motherboard and other system components in their anti-static
packaging until you are ready to install them.
2. Touch a grounded surface before you remove any system component from its
protective anti-static packaging. Unpacking and installation should be done
on a grounded, anti-static mat. The operator should be wearing an anti-static
wristband grounded at the same points as the anti-static mat.
3. After removing the motherboard from its original packaging, place only on a
grounded, anti-static surface, component side up. Immediately inspect the
board for damage. Due to shifting during shipping it is suggested that the
installer press down on the entire socket ICs to ensure they are properly
seated. Do this only with the board placed on a firm flat surface.
4. During configuration and installation touch a grounded surface frequently to
discharge any static electrical charge that may have built up in your body.
The best precaution, as stated above, is to wear a grounded wrist strap. When
handling the motherboard or an adapter card avoid touching its components.
Handle the motherboard and adapter cards either by the edges or by the
adapter card case-mounting bracket.
Misplaced Jumper Damage:
There are critical headers used for connectors or power
sources. These are clearly marked separately from the
jumpers listed in “Motherboard Layout”. Incorrectly setting
jumpers and connectors may lead to damage to your
motherboard. Please pay special attention to avoid
connecting these headers in the wrong directions.

3. INSTALLATION
3.1 Slots and Connectors
The SL5598 motherboard requires jumper setting for CPU type, voltage and speed.
Please refer to Jumper setting List in sec.3.2.2.

3. INSTALLATION
3.2 CPU (Central Processing Unit, U20)
The Pentium P54C/P55C, Cyrix 6X86L/6X86MX, IDT-C6 and AMD-K5/K6
processors have various voltage choices depending on the CPU suppliers. The
motherboard can also be upgraded with Pentium processors that run at higher speeds.
When upgrading the processor, use the BIOS configuration mode to change the
processor speed.
To complete CPU installation, please install CPU to socket firmly and arrange jumper
settings carefully, according to Section. 3.2.1 and 3.2.2.
C
3.2.1 Install CPU
The following steps install your CPU and configure the types, voltage and speed in
accordance to the Processor Jumper Setting List.
Step 1: Pull the handling bar of the socket upward to the other end to loosen the
socket’s openings.
Step 2: Place the CPU on the middle of the socket, orienting its beveled corner to
line up with the socket’s beveled corner. Make sure the pins of the CPU fit
evenly to the socket openings.
Handling
Bar
Step 1: Pull handling bar Step 2: Place CPU

3. INSTALLATION
Step 3: Replace the handling bar downward to fasten the CPU to the socket.
Warning : It is strongly recommended that a heatsink and CPU cooling fan be used to
prevent the CPU from overheating. Applying a thermal of jelly between the
CPU and the heatsink/fan will further cool the CPU.
3.2.2 Arrange Jumper Setting
Because different CPUs may require a varied configuration of Clock, CPU/BUS
speed, I/O voltage and Core voltage, please refer to the following Jumper setting list
to setup your jumper.
