There are many types of computer cases on the market. The motherboard
complies with the specifications for the micro-ATX system case. First, some
features on the motherboard are implemented by cabling connectors on the
motherboard to indicators and switches on the system case. Make sure that
your case supports all the features required. Secondly, 661FX-M supports one
or two floppy diskette drives and four enhanced IDE drives. Make sure that
your case has sufficient power and space for all the drives that you intend to
install.
Most cases have a choice of I/O templates in the rear panel. Make sure that
the I/O template in the case matches the I/O ports installed on the rear edge
of the motherboard.
This motherboard carries a micro-ATX form factor of 244 x 230 mm. Choose a
case that accommodates this form factor.

Follow these safety precautions when installing the motherboard:
• Wear a grounding strap attached to a grounded device to avoid
damage from static electricity.
• Discharge static electricity by touching the metal case of a safely
grounded object before working on the motherboard.
• Leave components in the static-proof bags they came in.
• Hold all circuit boards by the edges. Do not bend circuit boards.

Refer to the following illustration and instructions for installing the mother-
board in a case:
This illustration shows an ex-
ample of a motherboard being
installed in a tower-type case:
Note: Do not over-tighten
the screws as this
can stress the moth-
erboard.
Most system cases have
mounting brackets installed in
the case, which correspond to
the holes in the motherboard.
Place the motherboard over
the mounting brackets and
secure the motherboard onto
the mounting brackets with
screws.
Ensure that your case has an I/O template that supports the I/O ports and
expansion slots on your motherboard.

This section explains how to set jumpers for correct configuration of the moth-
erboard.
Setting Jumpers
Use the motherboard jumpers to set system configuration options. Jumpers
with more than one pin are numbered. When setting the jumpers, ensure that
the jumper caps are placed on the correct pins.
The illustrations below show a 2-pin jumper.
When the jumper cap is placed on both pins,
the jumper is SHORT. If you remove the
jumper cap, or place the jumper cap on just
one pin, the jumper is OPEN.
This illustration shows a 3-pin
jumper. Pins 1 and 2 are SHORT.

JP1: Clear CMOS jumper
Use this jumper to clear the contents of the CMOS RAM. You may need to
clear the CMOS RAM if the settings in the Setup Utility are incorrect and pre-
vent your motherboard from operating. To clear the CMOS RAM, disconnect
all the power cables from the motherboard and then move the jumper cap into
the CLEAR setting for a few seconds. Before clearing the CMOS, the AC
power of power supply should be removed.
JP3: BIOS Protect jumper
This jumper enables you to prevent the BIOS from being updated (flashed).
Short pin 1-2 if you are going to update your BIOS. After updating the BIOS,
short pin 2-3 to protect the BIOS from being flashed.

Connecting Case Components
After you have installed the motherboard into a case, you can begin connect-
ing the motherboard components. Refer to the following:
1. Connect the CPU
cooling fan cable to
CPUFAN1.
2. Connect the case
cooling fan connector
to CASFAN1.
3. Connect the case
speaker cable to
SPK1.
4. Connect the case
switches and indicator
LEDs to the PANEL1.
5. Connect the standard

Front Panel Connector
The front panel connector (PANEL1) provides a standard set of switch and
LED connectors commonly found on ATX or micro-ATX cases. Refer to the
table below for information:
Pin Signal Function Pin Signal Function
1 HD_LED_P Hard disk LED
(positive) 2 FP PWR/SLP MSG LED [dual color or single color (+)]
3 HD_LED_N Hard disk active LED
(negative) 4 FP PWR/SLP MSG LED [dual color or single color (-)]
5 RST_SW_N Reset Switch 6 PWR_SW_P Power Switch
7 RST_SW_P Reset Switch 8 PWR_SW_N Power Switch
9 RSVD Reserved 10 NC No pin
Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indica-
tion that data is being read from or written to the hard drive. For the LED to
function properly, an IDE drive should be connected to the onboard IDE inter-
face. The LED will also show activity for devices connected to the SCSI (hard
drive activity LED) connector.
Power / Sleep / Message Waiting LED
Connecting pins 2 and 4 to a single- or dual-color, front panel mounted LED
provides power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pins 5 and 7 to a momen-
tary-contact switch that is normally open. When the switch is closed, the board
resets and runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a
momentary-contact switch that is normally open. The switch should maintain
contact for at least 50 ms to signal the power supply to switch on or off. The
14

time requirement is due to internal de-bounce circuitry. After receiving a power
on/off signal, at least two seconds elapses before the power supply recog-
nizes another on/off signal.

Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the motherboard or any of the surface-mount resis-
tors with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the motherboard, you may cause serious damage to the mother-
board or its components.
On most motherboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you can
clearly see the motherboard and processor socket.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and
system bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the motherboard, or changing the
settings in the system Setup Utility. We strongly recommend that you do not
over-clock processors or other components to run faster than their rated
speed.
Warning: Over-clocking components can adversely affect the reliability of
the system and introduce errors into your system. Over-clocking can
permanently damage the motherboard by generating excess heat in com-
ponents that are run beyond the rated limits.
This motherboard has a Socket 478 processor socket. When choosing a
processor, consider the performance requirements of the system. Perform-
ance is based on the processor design, the clock speed and system bus
frequency of the processor, and the quantity of internal cache memory and
external cache memory.
15

CPU Installation Procedure
The following illustration shows CPU installation components:
Note: The pin-1 corner is marked with an arrow
Follow these instructions to install the Retention Module and CPU:
1. Install your CPU. Pull up
the lever away from the
socket and lift up to 90-
degree angle.
2. Locate the CPU cut
edge (the corner with the
pinhole noticeably
missing). Align and
insert the CPU correctly.
