Speaker Connector
An external speaker can be installed on the motherboard as a manufacturing option. An external speaker
can be connected to the motherboard at the front panel connector. The speaker (onboard or external)
provides error beep code information during the Power On Self-Test when the computer cannot use the
video interface. The speaker is not connected to the audio subsystem and does not receive output from the
audio subsystem.
Reset Button
This connector can be connected to a momentary SPST type switch that is normally open. When the switch
is closed, the motherboard resets and runs the POST.
Power LED Connector
This connector can be connected to an LED that will light when the computer is powered on.
Hard Drive LED Connector
This connector can be connected to an LED to provide a visual indicator that data is being read from or
writtento aharddrive.For theLED to function properly, an IDE drive must be connected to the onboard hard
drive controller.

After the IrDA interface is configured, files can be transferred from or to portable devices such as laptops,
PDAs, and printers using application software.

SMI (Sleep/Resume Switch)
When APM is enabled in the system BIOS, and the operating system’s APM driver is loaded, the system can
enter sleep (standby) mode in one of the following ways:
• Optional front panel SMI button
• Prolonged system inactivity using the BIOS inactivity timer feature
The 2-pin header located on the front panel I/O connector supports a front panel SMI switch, which must be
a momentary SPST type that is normally open.
Closing the SMI switch sends a System Management Interrupt (SMI) to the processor, which immediately
goes into System Management Mode (SMM).While the computer is in sleep mode it is fully capable of
responding to and servicing external interrupts (such as an incoming fax) even though the monitor turns on
only if a keyboard or mouse interrupt occurs. To reactivate or resume the system, the SMI switch must be
pressed again, or the keyboard or mouse must be used.
Power On Button
Thisconnector can be connected to a front panel power switch. The switch must pull the Power Button pin to
ground for at least 50 ms to signal the power supply to switch on or off. (The time requirement is due to
internal debounce circuitry on the motherboard). At least two seconds must pass before the power supply
will recognize another on/off signal.
1.3.2 ATX 20-pin Power Connector:
This connector supports the power button on-board. Using the ATX power supply, functions such as
Modem Ring Wake-Up and Soft Power Off are supported on this motherboard. This power connector
supports instant power-on functionality, which means that the system will boot up instantly when the power
connector is inserted on the board.

1.3.3 Hard Disk Connectors: IDE1 / IDE2
The motherboard has a 32-bit Enhanced PCI IDE Controller that provides PIO Mode 0~4, Bus Master, and
Ultra DMA 33 / 66 functionality. It has two HDD connectors IDE1 (primary) and IDE2 (secondary). You can
connect up to four hard disk drives, a CD-ROM, a 120MB Floppy (reserved for future BIOS) and other
devices to IDE1 and IDE2. These connectors support the IDE hard disk cable provided.
!"
IDE1 (Primary IDE Connector)
The first hard drive should always be connected to IDE1. IDE1 can connect a Master and a Slave drive. You
must configure the second hard drive on IDE1 to Slave mode by setting the jumper accordingly.
!"
IDE2 (Secondary IDE Connector)
The IDE2 controller can also support a Master and a Slave drive. The configuration is similar to IDE1. The
second drive on this controller must be set to slave mode.
1.3.4 Floppy Disk Connector: FDD1
The motherboard provides a standard floppy disk connector (FDC) that supports 360K, 720K, 1.2M, 1.44M
and 2.88M floppy disk types. This connector supports the provided floppy drive ribbon cables.
1.4 Back Panel Connectors
1.4.1 PS/2 Mouse / Keyboard Connector: CN1

1.5 Serial and Parallel Interface Ports
This system comes equipped with two serial ports and one parallel port. Both types of interface ports will be
explained in this chapter.
The Serial Interface Port : COM1 / COM2
The serial interface port is sometimes referred to as an RS-232 port or an asynchronous communications
port. Mice, printers, modems and other peripheral devices can be connected to a serial port. The serial port
can also be used to connect your computer with another computer system. If you wish to transfer the
contents of your hard disk to another system it can be accomplished by using each machine’s serial port.
The serial ports on this system has two 9-pin connector. Some older computer systems and peripherals
used to be equipped with only one 25-pin connector. As you need to connect your 9-pin serial port to an
older 25-pin serial port, you can purchase a 9-to-25 pin adapter.
Connectivity
The serial port can be used many ways, and it can be necessary to become familiar with the pin-out diagram.
The following chart gives you the function of each pin on the 9-pin connector and some of the 25-pin
connector. This information can be used when configuring certain software programs to work with the serial
port.
Signal Name DB9 PIN DB25 PIN
DCD Data Carrier Detect 1 8
RX Receive Data 2 3
TX Transmit Data 3 2
DTR Data Terminal Ready 4 20
GND Signal Ground 5 7
DSR Data Set Ready 6 6
RTS Request to Send 7 4
CTS Clear to Send 8 5
RI Ring Indicator 9 22
Special Applications
There are two types of serial devices that can be connected to a serial port. One of the devices is called
“DTE” (Data Terminal Equipment) and the other device is called “DCE” (Data Communications Equipment).
If a modem is connected to a computer, for example, the modem is called the DCE and the computer is
called the DTE. In situations such as this, the pins on the serial ports can be connected straight through.
In instances when there are two DTE devices connected together, such as a computer and a printer, a
special adapter called a “Null Modem” is needed to make communication between the two devices possible.
When using the serial port to communicate between devices, one problem in particular may arise. Some
manufacturers use one set of signals to begin communication with another device and other manufacturers
do not use these signals to initiate communication. If you encounter a communication problem that cannot
be resolved using a null modem, it can generally be assumed that one device is using the initialization

Motherboard Description
11
signals and the other device is not. This can usually be resolved by wiring the RTS, CTS, and DCD pins
together.
Serial Ports/COM Ports
The two serial ports on the computer are called COM1 and COM2, respectively. If you wish, two more serial
ports can be added onto the computer using optional hardware. Should you choose to add the extra Serial
ports (COM ports) they would be called COM3 and COM4.
When using serial ports to communicate with a peripheral device, be sure to assign only one COM port
number to each device. For example, if a printer and a scanner are both connected to your computer through
serial ports, the printer must be assigned one COM port (i.e. COM1) and the scanner must be assigned the
other COMport (i.e. COM2). No two devices can be assigned to one COM port. Each peripheral must have
its own COM port.
NOTE: Four serial ports may be installed on the computer. However, no more than two ports can be used
simultaneously.
*If you have installed an internal modem, be careful not to assign a COMport number that has already been
assigned to another device. This error is common.
When installing a device that is going to require the use of a serial port, use a diagnostic program to find out
which ports are available. It may be necessary to remove expansion cards that have serial ports in order to
check their jumper settings. The jumper settings will indicate which COM port the card has been assigned.
Checking the expansion card will eliminate mistakes in overlapping COM ports. Once you have completed
the installation of peripheral devices using the serial ports, be sure that the communication parameters such
as baud rate, parity bit, etc. are matching. If your computer is set for a baud rate of 9600 and your modem is
set for a baud rate of 2400 you will not be able to send messages. The manuals that accompany the
peripheral devices will inform you on the procedure for setting their parameters. Software manuals also have
instructions on setting parameters.
Parallel Interface Port : CN7A1
Unlike the serial port, parallel interface ports have been standardized and should not present any difficulty
interfacing peripherals to your system. Sometimes called a Centronics port, the parallel port is almost
exclusively used with printers. The parallel port on you system has a 25-pin, DB25 connector (see picture
below). The pin-out for the parallel port are shown in the table below.
