ChoosingaComputer Case
There are many types of computer cases on the market. The motherboard complies with
the specifications for the 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, 648FX-
A2 supports one or two floppy diskette drives and four enhanced IDE drives. Make sure
that your case has sufficient power and space for all 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 ATX form factor of 305 x 190 mm. Choose a case that
accommodates this form factor.
Most system cases have mounting brackets installed in the case, which correspond 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.

CheckingJumperSettings
This section explains how to set jumpers for correct configuration of the motherboard.
SettingJumpers
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 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

InstallingtheMotherboard
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 momentary-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 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.

13
InstallingtheMotherboard
This motherboard has a Socket 478 processor socket. When choosing a processor, consider
the performance requirements of the system. Performance 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
powercabletothe CPUFAN connector. This
completes the installation.
CPU Installation Procedure
The following illustration shows CPU installation components.
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 installa-
tion procedures may vary with the type of CPU fan/heatsink supplied. The
form and size of fan/heatsink may also vary.
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.

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 explains how to do this.
Installing a Hard Dish Drive/CD-ROM/SATAHard Drive
This section describes how to install IDE devices such as a hard disk drive and 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.
