Speaker onnector
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.
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 onnector
This connector can be connected to an LED that will light when the computer is
powered on.
Hard Drive LED onnector
This connector can be connected to an LED to provide a visual indicator 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 onnector
After the IrDA interface is configured, files can be transferred from or to portable
devices such as laptops, PDAs, and printers using application software.
Sleep Button
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.
1-8

Chapter 1 Motherboard Description
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
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 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 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.
1.3.3 ard 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, Ultra DMA / 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 onnector)
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 onnector)
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 ATX 20-pin 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
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 parallel port. Both types
of interface ports will be explained in this chapter.
The Serial Interface: OM1/ OM2
The serial interface port is sometimes referred 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 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 have two 9-pin connectors. 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.
