Speaker Connector

An offboard speaker can be installed on the motherboard as a manufacturing
option. An offboard speaker can b e connected to the motherboard at the fron t
panel connector. The speaker (onboard or offboard) provides error beep code
information du ring the Power On Self-Test w hen the computer cannot use the
video interfac e. T he speaker is n o t connected to the audio sub s ystem and do es n ot
receive output from the audio subsystem.

Reset Button

This connector can be connected to a momentary SPST type switch that is
normally open. Wh en the switch is cl osed, the motherboard r esets and runs th e
POST.

Power LED Connector

This connector can b e conn ected to an L ED th at wil l fla shin g wh en the co mput er
is slee ping .

Hard Drive LED Connector

This connector can be c onn ect ed t o an LE D t o provi d e a visu al ind icator that data
is being read from or written to a hard drive. For the LED to function properly, an
IDE drive must be connected to the onboard hard drive controller.

Infrared Connector

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

Green (Sleep/Resume) Switch

When APM is enabl ed 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:

• Optiona l fro nt pane l SM I butto n

• Prolonged syst e m ina c t ivi ty us ing the BIOS inac t iv ity ti m e r 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 th e SMI switch sends a System Manage ment Interrupt (SMI) to

Chapter 1 Motherboard Description

1-11

the processor, which immediately goes into System Management Mod e
(SMM).While the computer is in sleep mode it is fully capable of
respondin g to and servi cing ext ernal interr upts (su ch as an incomi ng 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 (Use ATX Power)

This connector can be connect ed to a front pan el power swit ch. 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 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 (p rimary) and IDE2 (secondary). You can connect up to four
hard disk drives , a CD-ROM, a 120M B Floppy (reserved for f uture BIOS) and
other devices to IDE1 and IDE2. These connectors support the IDE hard disk
cable prov ide d.

• IDE1 (Primary IDE Connector)

The first hard drive shou ld always be connected to IDE1. IDE1 can connect a
Master and a Slave d rive. You mu st configure th e second hard dri ve 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.

1.3.3 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 driv e ribbon cables.

Chapter 1 Motherboard Description

1-12

1.3.4 ATX Power Connector (JATXPWR1)

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 function ality, which means tha t th e system will b oot up instan tly wh en
the power connector is inserted on the board.

1.4 Serial and Parallel Interface Ports

This system is equ i pped with on e s erial p orts an d one par a llel por t. Both typ es of
interface ports will be e xpla i ne d in this cha pt e r.

The Serial Interface Port

The serial interface port is sometimes referred to as a 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 h ard disk to another system it can be acco mpl is hed by using each
machine‘s serial port.

The serial ports on this system have two types of connectors, one 9-pin and one
25-pin. Some older computer systems and peripherals may only have a 25-pin
connector. Should you need to connect your 9-pin serial port to a 25-pin serial
port, you can purchase a 9-to-25 pin adapter.

Chapter 1 Motherboard Description

1-14

Connectivity

The many ways that a serial port can be used make it necessary to be familiar with
the pinout dia gram. T h e f ollowin g chart gi ves yo u th e fu nct ion of each pi n on th e
9-pin conn ector. T his i nfor matio n can b e used when con figuri ng certai n sof twar e
programs to work with the serial port.

Special Applications

There are two types of serial d evices that can be connected to a s erial port. One of
the devices is called “ DTE” (Data T erminal Equip ment) and the other devic e 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 situati ons such as this, th e pins on the serial ports can be conn ected
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 enco unter a communication problem that
cannot be resolved using a null modem, it can generally be assumed that one
device is using the initialization signals and the other device is not. This can
usually be resolved by wiring the RTS, CTS, and DCD pins together.

Serial Port/COM Port

The one serial port on the computer is called JCOM1, respectively. If you wish,
two more serial ports can be added onto the co mputer using opt ional hardware.
Should you choose to add the extra Serial ports (COM ports), they would be
called JCOM3.

When using serial ports to communicate with a peripheral devices, b e sure to
assign only one COM port number to ea ch devi ce. For ex ampl e, if a printer an d a
scanner are both connected to your computer through serial ports the printer must
be assigned one C OM port (i.e. COM1) and the scann er must be assigned the
other COM port (i.e. COM2). No two devices can be assigned to one COM port.
Each peripher al m us t hav e its own COM port.

NOTE: Two serial ports may be installed on the computer. However,
no more than two ports can be used simultaneously.

*If you have inst alled an internal mod em, be careful not to ass ign a COM port
number that has already been assigned to another device. This error is common.

When installing a d evice that is going to requ ire the use of a serial port, us e 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 j umper settings will indicat e which COM port the card ha s 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 co mmunication par ameters such as baud rat e,
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 will also have
instructions o n se tt ing param e ters.

Parallel Interface Port

Unlike the serial port, parallel interface ports have been standardized and should
not present any difficulty interfacing peripherals to your system. Sometimes
called Centronics port, the parallel port is almost exclusively used with printers.
The parallel port on your system has a 25-pin Connector (see picture below). The
pinouts for the parall el port are shown in the table below .
