Chapter1 Motherboard Description

Speaker Connector

An offboard speaker can be installed on the motherboard as a manufacturing
option. An offboard speaker can be connected to the motherboard at the front
panel connector. The speaker (onboard or offboard) provides error beep code
information during the Power On Self-Test when the computer cannot use the
video interface. Th e speaker is not co n n ected to the au d i o subsystem and do es not
receive output from the audio subsystem.

Hard Drive LED Conn e ct or

This connector can be con nect ed to an LED to pro vid e a vis ual in di cator tha t da ta
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.

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.

IrDA (I nfrared) Connector

After the IrDA interface i s co nfigu red , files can b e tr ansferred from o r to portable
devices such as lapto p s , P D As, an d printers using application software.

Power LED Conne c tor

This connect or can be c onnected to an LED t hat will ligh t when the computer is
powered on.

Power On Button

This connector 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 requi rement is du e to in tern al deb ou nce circu itr y on
the motherboar d.) At least two seconds must pass before the power s upply will
recognize another on/off signal.

Sleep /Resume Switch Connector

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 sleep/r esume button
 Prolonged system inactivity using the BIOS inactivity timer feature

1-10

Chapter1 Motherboard Description

The 2-pin connector located on the front panel I/O connector supports a front
panel sleep/resume switch, which must be a momentary SPST type that is
normally open.

Closing th e sleep/resume switch se nds a System Management Interrupt (SMI) to
the processo r, wh ich immediate ly goes i nto SM M. Whil e t he co mput er i s i n sl eep
mode, it is fully capable of respond ing to and servicing external in terrupts (such
as an incoming fax) even though t h e monitor turns on on ly if a keyboard or mouse
interrupt occurs. To reactivate or resume system operation, the sleep/resume
switch must be pressed again , o r th e keybo ard o r mou se must be used .

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 expla in ed in this chapter.

The Serial Interface Port-I : JCOM1

The serial interface port is sometimes referred to as an RS-232 port or an
asynchronous co mmunications port. Mice, printer s, modems and othe r peripher al
devices can be connected to a serial port. The serial port can also be used to
connect your co mputer with anoth er computer system. If you wish t o transfer the
contents of your hard d i sk to another system it can b e accomplished by u sin g each
machine’s serial port.

The serial ports on this system have two 9-pin connector. Some older computer
systems and peripherals used to be equipped with only one 25-pin connector.
Should 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.

1-17

Chapter1 Motherboard Description

Connectivity

The serial port can be used many ways, and it may be necessary to become
familiar with the pin -out diagram. The following chart gives you th e function of
each pin on the 9-pin connector and some of the 25-pin connector. This
information can be u sed when configuring certain software programs to work with
the serial port.

Special Applications

There are two types of serial devices that can be con nect ed to a serial p ort . One of
the devices is cal led “DTE” (Data Terminal E quipment) and t he other devi ce is
called “DCE” (Data Communicat ions 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 sit uations s uch as thi s, the pin s on the ser ial port s can b e 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

1-19

Chapter1 Motherboard Description

signals to initi ate co mmunic ation. If you encou n t er 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 re solved by wiring the RTS, CTS, and DCD pins tog ether.

Serial Ports/COM Ports

The two serial ports on the computer are called COM 1 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 po rt numb er to each devi ce. For example, if a prin ter an d a
scanner are both co n n ected to your computer thro u gh serial ports, th e p rinter must
be assigned one COM port (i.e. COM1) and the scanner must be assigned the
other COM port (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 a n internal modem, be careful not to assign a COM port
number that has alread y been assign ed to another device. This error is common.

When installing a d evice that is going to requ ire the use of a serial port , use a
diagnostic pr ogram to find out which p orts 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

1.6.2 How to install a DIMM Module

1. The DIMM socket has a Plastic
Safety Tab and the DIMM
memory module has an
asymmetrical notch, so the
DIMM memory module can only
fit into the slot in one direction.

2. Push the tabs out. Insert the
DIMM memory modules in to the
socket at a 90-degre e angle then
push down vertically to fit the
modules into place.

3. The mounting holes and plastic
tabs should fit over the edge and
hold the DIMM memory modules
in place.

Soft-Off by PWR-BTTN

2-24

Chapter2 BIOS Setup

Pressing the power bu tton fo r more than 4 second s forces th e system to ent er the
Soft-Off state when the system has “hung.”

The Choices: Delay 4 Sec, Instant-Off (default)

Wake-Up by PCI card

When you select Enabled, a PME sign al from PCI card ret urns the system to Ful l
On state.

The Choices: Enabled, Disabled (default).

Power On by Ring

An input signal on the serial Ring Indicator (RI) line (in other words, an incoming
call on the modem) awakens the system from a soft off state.

The Choices: Enabled (default), Disabled.

PWRON After PWR-Fail

This field determines th e actio n the system will aut omatically take whe n po wer is
restored to a system that had lost power previously without any subsequent
manual intervent ion. There ar e 3 sources th at provide c urrent to the CMOS area
that retains th es e Power-On instr u ctions; the moth erb o ard battery (3V), the Power
Supply (5VSB), and the Power Supply (3.3V). While AC is not supplying power,
the motherboard uses the mo therboa rd batter y (3V). I f AC power is s upplie d and
the Power Supply is not turned on, 5VSB from the Power Supply is used. When
the Power Supply is eventually on 3.3V from the Power Supply will be used.
There are 3 options : “F ormer-Sts”, “On”, “Off”.
“Former” Means to maintai n the last status of the CMOS when

“On” Means always set CMOS to th e “O n ” statu s when AC
power is lost.
“Off” (default) Means always set CMO S to th e “O ff” status whe n AC
power is lost.
For example: If set to “Formar-Sts” and AC power is lost when system is live ,
then after AC power is restored, th e system will automatically power on. If AC
power is lost when system is not li ve, system will remain po wered off.

AC power is lost.

second the system will boot up .

Note: If you have change the setting, you must let the system boot up until it

goes to the opera ting system, befo re th is function will work .

Reload Global T imer Events

Reload Global Timer Events are I/O events whose occurrence can prevent the
system from entering a power saving mode or can awaken th e system from such a
mode. In effect, the system remains al ert for anything, which occurs to a device,
which is configured as Enabled, even when the system is in a power down mode.

2.7 PnP/PCI Configurations

This section describes configuring the PCI bus system. PCI, or Personal
Computer Interco nnect , is a system which allo ws I/O d evices to operat e at sp eeds
nearing the s peed the CP U itself uses when communicating with its own special
components. This section covers some very technical items and it is strongly
recommended that only experi enced users sh ou ld make any changes to the defaul t
settings.

Figure 7. PnP/PCI Configurations

2-27

Chapter2 BIOS Setup

Reset Configuration Data

The system BIOS suppo rts the PnP feature so the s ystem needs to record which
resource is assigned and proceeds resources from conflict. Every peripheral
device has a node, which is called ESCD. This node records which resources
are assigned to it. Th e system needs to recor d an d upd ate ES CD to th e memory
locations. These locations (4K) are reserved at the system BIOS.
If Disabled (default) i s ch o sen , th e system’s E S C D will u p date only when t h e n ew
configuration varies from the last one.
If Enabled is chosen, the system is forced to update ESCDs and then is
automatically set to the “Disabled” mode.
The Choices: Disabled (default), Enabled.

Resources Controlled By

By Choosing “Auto(ESCD)”(default) the system BIOS will detect the system
resources and auto mati call y assign th e rel ative IRQ channel for each perip h eral.
By Choosing “Manual ”, the user will need to assign I RQ for add-on car ds. Be
sure that there are no IRQ and I/O port conflicts.

IRQ-3 assigned to PCI Device
IRQ-4 assigned to PCI Device
IRQ-5 assigned to PCI Device
IRQ-7 assigned to PCI Device
IRQ-9 assigned to PCI Device
IRQ-10 assigned to PCI Device
IRQ-11 assigned to PCI Device
IRQ-12 assigned to PCI Device
IRQ-14 assigned to PCI Device
IRQ-15 assigned to PCI Device

The above settings will be sh own on the screen on ly if “Manual ” is cho sen for the
Resources Controlled By function.

IRQ Resources

When resources are controlled manually, assign each system interrupt a type,
depending on the type of device using the interrupt.

PCI / VGA Palette Snoop

Choose Disabled or Enabled. Some graphic controllers which are not VGA
compatible take the ou tput from a VGA controller and map it to thei r displ ay as a
way to provide boot information and VGA compatibi lity.

Disabled (default) Disables the function .
Enabled Enables the function.
