Precautions
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 beginning 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, only place it 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 not to connect
these headers in the wrong directions.

3. INSTALLATION
3.1 Slots and Connectors
The IN5598 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)
The Pentium P54C/P55C, Cyrix 6X86L/MX/MII, IDT-C6, AMD-K5/K6 processors
have various voltage choices depending on the CPU suppliers. Also this motherboard
can 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, presented in sec. 3.2.1 and 3.2.2.
3.2.1 Install CPU
The following steps detail how to install your CPU and configure the types, voltage and
speed according 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 to its original position to fasten the CPU into place.
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
Due to different CPU require a varied configuration of Clock, CPU/BUS speed, I/O
voltage and Core voltage. Please refer to the following Jumper setting list exactly to
setup your jumper.
