Static Electricity Damage:
Static electricity can easily damage your motherboard.
Observing a few basic precautions can help safeguard
against damage that could result in expensive repairs.
Follow the simple measures below to protect your
equipment from static electricity damage:
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 all of the 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 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 wrong directions.
3. INSTALLATION

3.1 Slots And Connectors
This motherboard requires no jumper setting for CPU speed. All settings will be
completed in BIOS. In Chapter 4, you will be navigated to set the CPU speed in BIOS
Features Setup Menu. This motherboard will automatically configure a correct
voltage for the CPU making voltage jumpers
unnecessary.
In following pages, the triangle smark stands for
pin 1 of connectors.

3.2 CPU (Central Processing Unit)
This motherboard provides a Single Edge Contact (SEC) slot and a Bridges on the
board for the Pentium II processor packaged in an SEC cartridge. This cartridge
includes the processor core, second-level cache, thermal plate and black cover. When
mounted in Slot 1, the processor is secured by a retention mechanism attached to the
motherboard.
Also this motherboard can be upgraded with Pentium II processors that run at
higher speeds. When upgrading the processor, use the BIOS configuration mode
to change the processor speed.
First, please ensure the following parts we received with this motherboard:
In your Packaging, one Pentium II Retention Mechanism is attached and one pair of
Mount Bridges are installed on the motherboard.
3. INSTALLATION
1. Pentium II Retention
Mechanism
2. Mount Bridges (One pair,
installed on motherboard
already)

17
Next follow the following steps to complete CPU Installation.
Step 1:
Place the Pentium II
Retention Mechanism over
the CPU slot (SEC slot) on
motherboard. It is designed
to fit only one way into
CPU slot.
Step 2:
Fix the Pentium II Retention Mechanism to the
motherboard by screwing the four captive nuts
tight to Mounting Bridges.
Step 3:
Push the SEC Cartridge’s two
locks (shown as right) inward
and insert the CPU (SEC
Cartridge) to Retention
Mechanism. Press the top of
CPU gently but firmly until it
is fully inserted.
Finally, make sure the SEC
Cartridge has been installed
Properly, then connect the CPU Heatsink Fan cable to the onboard CPU Fan
header (J13).

3.3 System Memory (DRAM )
3.3.1 DIMM (Dual Inline Memory Module)
The KR632 features three 168-pin DIMM sockets, each supporting 8MB, 16MB,
32MB, 64MB and 128 MB of SDRAM/EDO. Memory can be installed in one, two or
all three sockets. Memory size and speed can vary between sockets. Also variable
memory can be combined for a total memory of 8MB to 384MB with variable
combination. The BIOS will automatically detects memory type, size and speed.
3.3.2 Installation Procedure
Step1: Pin 1 of the DIMM must match
pin 1 of the DIMM socket.
Step2: Insert the DIMM module into
the DIMM socket at a 90 degree angle.
If pin 1 of the DIMM module does not
line up with pin 1 of the socket, the
DIMM module will not insert correctly
into the socket.
Step 3: After inserting the DIMM module completely into the socket, push up on the
socket latches securing the DIMM into place.
Be careful not to misfit the DIMM Module into DIMM sockets in wrong direction.
This module can be inserted into DIMM socket only one way. Please note the “ss”
for pin 1 location.
To release the memory module, push both latches down and carefully rock the
module forward and backward while slowly lifting it upward.

3.3.3 DIMM Combination
Each DIMM socket can be inserted with 8MB, 16MB, 32MB, 64MB, 128MB DIMM
or empty. The total combinations are, 6*6*6, 216 selections. You can refer to following
figure to select one way to insert your DIMM, for example:
To select 1 out of 6 items (empty, 8MB, 16MB, 32MB, 64MB, 128MB) in DIMM3.
Then, repeat again in DIMM2, DIMM1 to go through your own path.
A total of 216 combinations ensure you can insert your DIMM modules any way
you prefer.
