Chapter 1 Motherboard Description

RST (Reset Button)

This connector can be attached to a momentary SPST switch. This switch is usually
open and when closed will cause the motherboard to reset and run the POST
(Power On Self Test).

POW-LED (Power LED Connector)

This connector can be attached to an LED on the front panel of a computer case.
The LED will illuminate while the computer is powered on.

HLED (Hard Drive LED Connector)

This connector can be attached to an LED on the front panel of a computer case.
The LED will flicker during disk activity. This disk activity only applies to those
IDE drives directly attached to the system board.

IR (Infrared Connector)

This connector is used to attach to an infrared sensing device. After the IrDA
interface is configured, connectionless data transfer to and from portable devices
such as laptops, PDAs is possible.

SLP (Sleep/Green Button)

This connector is used to conserve energy by powering down the monitor and the
hard disk when not in use. To configure this option, you need to connect a button
from the front panel to this connector. Depressing the button will power down the
monitor and hard drives until the system is invoked by any keyboard activity,
mouse activity, modem activity or when the sleep button is depressed again.
APM (Advanced Power Management) must be enabled in the system BIOS and the
APM driver must be loaded.

ON/OFF (Power Button)

This connector can be attached 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 required is due to internal debounce circuitry on the
system board). At least two seconds must pass before the power supply will
recognize another on/off signal.

1.7.4 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.

1.7.4.1 The Serial Interface: JCOM1

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.

1-26

Chapter 1 Motherboard Description

Connectivity

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

1.7.4.2 Parallel Interface Port: JPRNT1

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, DB25 connector (see picture below). The
pinout for the parallel port are shown in the table below.

2.7 PnP/PCI Configurations

This section describes configuring the PCI bus system. PCI, or Personal Computer
Interconnect, is a system which allows I/O devices to operate at speeds nearing the
speed of the CPU itself uses when communicating with its own special components.
This section covers some very technical items and it is strongly recommended that
only experienced users should make any changes to the default settings.



Figure 7. PnP/PCI Configurations

Reset Configuration Data

The system BIOS supports the PnP feature which requires the system to record
which resources are assigned and protects resources from conflict. Every
peripheral device has a node, which is called ESCD. This node records which
resources are assigned to it. The system needs to record and update ESCD to the
memory locations. These locations (4K) are reserved in the system BIOS. If the
Disabled (default) option is chosen, the system‘s ESCD will update only when the
new configuration varies from the last one. If the Enabled option is chosen, the
system is forced to update ESCDs and then is automatically set to the “Disabled”
mode.

The Choices: Disabled (default), Enabled.

2-24

Chapter 2 BIOS Setup

Resources Controlled By

By Choosing “Auto” (default), the system BIOS will detect the system resources
and automatically assign the relative IRQ and DMA channel for each peripheral.
By Choosing “Manual”, the user will need to assign IRQ & DMA for add-on cards.
Be sure that there are no IRQ/DMA and I/O port conflicts.

IRQ Resources

This submenu will allow you to assign each system interrupt a type, depending on
the type of device using the interrupt. When you press the “Press Enter” tag, you
will be directed to a submenu that will allow you to configure the system interrupts.
This is only configurable when “Resources Controlled By” is set to “Manual”.

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

Legacy is the term, which signifies that a resource is assigned to the ISA Bus and
provides non-PnP ISA add-on cards. PCI / ISA PnP signifies that a resource is
assigned to the PCI Bus or provides for ISA PnP add-on cards and peripherals.

PCI / VGA Palette Snoop

Choose Disabled or Enabled. Some graphic controllers which are not VGA
compatible take the output from a VGA controller and map it to their display as a
way to provide boot information and VGA compatibility.
However, the color information coming from the VGA controller is drawn from the
palette table inside the VGA controller to generate the proper colors, and the
graphic controller needs to know what is in the palette of the VGA controller. To
do this, the non-VGA graphic controller watches for the Write access to the VGA
palette and registers the snoop data. In PCI based systems, where the VGA
controller is on the PCI bus and a non-VGA graphic controller is on an ISA bus, the
Write Access to the palette will not show up on the ISA bus if the PCI VGA
controller responds to the Write.

2-25

Chapter 2 BIOS Setup

In this case, the PCI VGA controller should not respond to the Write, it should only
snoop the data and permit the access to be forwarded to the ISA bus. The
non-VGA ISA graphic controller can then snoop the data on the ISA bus. Unless
you have the above situation, you should disable this option.

The Choices: Disabled (default), Enabled.
