Installing the Motherboard
Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual
indication 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 interface. 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 pin 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 main-
tain contact for at least 50 ms to signal the power supply to switch on or off.
The 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
recognizes another on/off signal.
InstallingHardware
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 resistors 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 motherboard 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 components that are run beyond the
rated limits.

661FX-M Deluxe accommodates two 184-pin 2.5V unbuffered Double Data
Rate (DDR) SDRAM (Synchronous Dynamic Random Access Memory)
memory modules. 661FX-M Deluxe can support DDR400/DDR333/DDR266
memory modules and allow to maximum memory size 2 GB.
DDR SDRAM memory module table
This motherboard has a Socket 478 processor socket. When choosing a
processor, consider the performance requirements of the system. Perfor-
mance 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.
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
pin hold noticeably missing). Align and insert
the CPU correctly.
3. Press the lever down and apply thermal
grease on top of the CPU.
4. Put the CPU Fan down on the retention
module and snap the four retention legs of
the cooling fan into place.
5. Flip the levers over to lock the heat sink in
place and connect the CPU cooling Fan
power cable to the CPUFAN connector. This
completes the installation.
To achieve better airflow rates and heat dissipation, we suggest
that you use a high quality fan with 4800 rpm at least. CPU fan
and heatsink installation procedures may vary with the type of
CPU fan/heatsink supplied. The form and size of fan/heatsink
may also vary.
The motherboard accommodates two memory modules. You must install at
least one module in any of the two slots. Each module can be installed with
128 MB to 1 GB of memory; total memory capacity is 2 GB.
Do not remove any memory module from its antistatic packag-
ing until you are ready to install it on the motherboard. Handle
the modules only by their edges. Do not touch the components
or metal parts. Always wear a grounding strap when you handle
the modules.

a CD-ROM drive.
AboutIDE Devices
Your motherboard has a primary and secondary IDE channel interface (IDE1
and IDE2). An IDE ribbon cable supporting two IDE devices is bundled with
the motherboard.
You must orient the cable connector so that the pin1 (color)
edge of the cable correspoinds to the pin 1 of the I/O port
connector.
IDE1: Primary IDE Connector
The first hard drive should always be connected to IDE1.
IDE2: Secondary IDE Connector
The second drive on this controller must be set to slave mode. The
cinfiguration is the same as IDE1.

12
Installing the Motherboard
Installing a Floppy Diskette Drive
The motherboard has a floppy diskette drive (FDD) interface and ships with
a diskette drive ribbon cable that supports one or two floppy diskette drives.
You can install a 5.25-inch drive and a 3.5-inch drive with various capacities.
The floppy diskette drive cable has one type of connector for a 5.25-inch
drive and another type of connector for a 3.5-inch drive.
You must orient the cable connector so that the pin 1 (color)
edge of the cable corresponds to the pin 1 of the I/O port
connector.
IDE devices enclose jumpers or switches used to set the IDE device as
MASTER or SLAVE. Refer to the IDE device user’s manual. Installing two
IDE devices on one cable, ensure that one device is set to MASTER and the
other device is set to SLAVE. The documentation of your IDE device ex-
plains how to do this.
AboutSATAConnectors

Installing the Motherboard
Installing Add-on Cards
The slots on this motherboard are designed to hold expansion cards and
connect them to the system bus. Expansion slots are a means of adding or
enhancing the motherboard’s features and capabilities. With these efficient
facilities, you can increase the motherboard’s capabilities by adding hardware
that performs tasks that are not part of the basic system.
Before installing an add-on card, check the documentation for
the card carefully. If the card is not Plug and Play, you may
have to manually configure the card before installation.
Follow these instructions to install an add-on card:
1. Remove a blanking plate from the system case corresponding to
the slot you are going to use.
2. Install the edge connector of the add-on card into the expansion
slot. Ensure that the edge connector is correctly seated in the
slot.
3. Secure the metal bracket of the card to the system case with a
screw.
For some add-on cards, for example graphics adapters and
network adapters, you have to install drivers and software be-
fore you can begin using the add-on card.
AGP Slot The AGP slot is used to install a graphics adapter that
supports the 8x/4x AGP specification. It is AGP 3.0
compliant.
PCI Slot
CNR Slot This slot is used to insert CNR cards with Modem and
Audio functionality.
661FX-M Deluxe is equipped with three standard PCI
slots. PCI stands for Peripheral Compponent Inter-
connect and is a bus standard for expansion cards, which
