1.3.1 Front Panel Connector (PANEL)

PANEL Connector

Speaker Connector (SPEAKER)

An offboard speaker can be installed onto the motherboard as a

manufacturing option. An offboard speaker can be connected to

the motherboard at the front pannel connector. The speaker

(onboard or offboard) provides error beep code information

during the Power 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.

Hard Drive LED Connector (HD_LED)

This connector supplies power to the cabinet IDE activity LED.

Read and write activity by devices connected to the Primary or

Secondary IDE connectors will cause the LED to light up.

SMI Suspend Switch Lead (EXTSMI) (Disabled)

This allows the user to manually place the system into a suspend

mode of Green mode. System activity will be instantly decreased

to save electricity and expand the life of certain components

when the system is not in use. This 2-pin connector (see the

figure) connects to the case-mounted suspend switch. If you do

not have a switch for the connector, you may use the "Turbo

Switch” instead since it does not have a function. SMI is

activated when it detects a short. It may require one or two

pushes depending on the position of the switch. Wake-up can be

controlled by settings in the BIOS but the keyboard will always

allow wake-up (the SMI Suspend Switch Lead cannot wake-up

the system). If you want to use this connector, the "Suspend

Switch" in the Power Management Setup of the BIOS SOFT-

WARE section should be on the default setting of Enable.

ATX Power Switch (PW_BN)

The system power is controlled by a momentary switch

connected to this lead. Pushing the button once will switch

the system ON. The system power LED lights when the

system's power is on .

Power LED Lead (PW_LED)

The system power LED lights when the system power is on.

Keyboard Lock (KBLOCK)

The header is for setting keyboard locked.

Reset Switch Lead (RESET)

The 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.

1.3.2 Floppy Disk Connector (FDC)

This connector supports the provided floppy drive ribbon

cable. After connecting the single end to the board, connect

the two plugs on the other end to the floppy drives.

1.3.3 Hard Disk Connectors (IDE1/IDE2)

These connectors support the provided IDE hard disk ribbon

cable. After connecting the single end to the board, connect

the two plugs at the other end to your hard disk.

If you install two hard disks, you must configure the second

drive to Slave mode by setting its jumper settings. BIOS now

supports SCSI device or IDE CD-ROM boot up (see "HDD

Sequence SCSI/IDE First" & "Boot Sequence" in the BIOS

Features Setup of the BIOS SOFTWARE) (Pin 20 is removed

to prevent inserting in the wrong orientation when using

ribbon cables with pin 20 plugged) .

-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.

-ATX 4-pin power connector only support +12V voltage.

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 Interfaces: COM1/COM2

The serial interface port is sometimes refered to as an RS-

232 port or an asynchronous communication 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 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 port on this system has one 9-pin connector.

Some older computer systems and peripherals used to be

equipped with only a 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.

Parallel Interface Port

Unlike serial ports, 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 your system has a 25-pin, DB 25 connector(see

the picture below).
