1.3.1 Front Panel Connector(J1)
J1 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 dur-
ing the Power Self-Test when the computer cannot use the vedio
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 (SMI)
This allows the user to manually place the system into a suspend
mode or Green mode where systematic activity will be instantly
decreased to save electricity and expand the life of certain com-
ponents when the system is not in use. This 2-pin connector
(see the figure below) 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 to open moment and
therefore leaving it shorted will not cause any problems. 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 lead cannot
wake-up the system). If you want to use this connector, "Sus-
pend 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.
SMI LED Lead (SMI_LED)
The system SMI LED lights when the system suspend is on.
Reset Switch Lead (RST)
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(FDD1)
This connector supports the provided floppy drive ribbon
cable. After connecting the single end to the board, connect
the two plug 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 rib
bon cables with pin 20 plugged) .

1.3.4 ATX 20-pin Power Connector(PW1)
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.

1.5 Serial and Parallel Interface Ports
This system comes equipped with two serial ports and one
parpllel 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 have one 9-pin connector.
Some older computer systems and peripherals used to be
equipped with only 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 the serial ports, parallel interface port has 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, DB 25 connector(see
picture below).
