InstallingtheMotherboard
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.
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.

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.

13
InstallingtheMotherboard
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.
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 Flipthe leversover to lock the heat sink in place and
connect the CPU cooling Fan power cable to the
CPUFAN connector. This completes the installa-
tion.

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.
AboutUltraDMA
This motherboard supports UltraDMA 133/100/66. UDMA is a technology that acceler-
ates the performance of devices in the IDE channel. To maximize performance, install IDE
devices that support UDMA and use 80-pin IDE cables that support UDMA 133/100/66.
Installing a Hard Disk Drive/CD-ROM
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.

16
InstallingtheMotherboard
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 capabili-
ties by adding hardware that performs tasks that are not part of the basic system.
FDD1:Floppy DiskConnector
This connector supports the provided floppy
drive ribbon cable. After connecting the single
end to the onboard floppy connector, connect
the remaining plugs on the other end to the
floppy drives correspondingly.
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.
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.
AGP Slot
PCI Slot This motherboard is equipped with three standard PCI slots. PCI stands for
Peripheral Component Interconnect and is a bus standard for expansion
cards, which for the most part, is a supplement of the older ISA bus stan-
dard. The PCI slots on this board are PCI v2.2 compliant.
The AGP slot is used to install a graphics adapter that supports the 4X AGP
specification. It is AGP 2.0 compliant.
CNR Slot This slot is used to insert CNR cards with Modem and Audio functionality.
