NOTE : The material in this manual is for information only and is subject to
change without notice. We reserve the right to make changes in the product
design without reservation and without notification to its users. We shall not be
liable for technical or editorial omissions made herein; nor for incidental or
consequential damages resulting from the furnishing, performance, or use of
this material.

Something Interesting
This section provides useful information that you will need to know should you
decide to modify or upgrade the configuration of the mainboard and the system
it is installed in. If you do not have the confidence to upgrade the mainboard
yourself, we advise that you consult a qualified service technician for
assistance.
The BIOS Setup Utility
The BIOS (Basic Input Output System) is the basic firmware that instructs the
computer how to operate. For the BIOS to work properly, there must be a
record of the computer's hardware and configuration settings for it to refer to.
This record is created using the Setup Utility, a program that is stored
permanently in the BIOS ROM chip on the mainboard.
The system configuration record created by the Setup Utility is also stored on
the mainboard, but not permanently. This section of the memory it is stored is
in the NVRAM.
When you buy your computer, the system configuration record will already be
set and may in some cases differ from the basic defaults. The first time you use
your computer or when you need to re-configure your system, you should run
the Setup Utility and write down the settings.

PA-2006 Mainboard Manual

IRQ Functionality
As you read through this manual, you will see the term IRQ on a number of
occasions. It is important for you to know what this term means, particularly if
you intend to upgrade your system.
IRQ stands for Interrupt Request, the process in which an input or output
device tells the processor to temporarily interrupt its current task and
immediately process something from the source of the interrupt. When it has
completed this, the processor returns to the task it was already processing.
Devices that need an
IRQ line to operate sometimes need to have exclusive use of that line.
A large number of add-on cards, such as sound cards and LAN cards, require
the use of an IRQ line to function. Some of IRQs may already be in use by
components in the system such as the keyboard and mouse. Add-on cards that
need to use an IRQ draw from the unused group of IRQs. When installing a
card that uses an IRQ, it will have a default IRQ setting which you might have
to change if that IRQ is already in use and cannot be shared.
Both ISA and PCI add-on cards may need to use IRQs. System IRQs are
available to add-on cards installed on the ISA bus first; the remaining ones can
be used by cards installed on the PCI bus. There are two categories of ISA add-
on cards: so-called Legacy ISA cards, which need to be configured manually
and then installed in any available ISA slot; and Plug and Play (PnP) ISA
cards, which are configured automatically by the system. As a result, when you
install Legacy ISA cards, you have to carefully configure the system to ensure
that the installed cards do not conflict with each other by having the same IRQ.
With PnP cards, on the other hand, IRQs are assigned automatically from the
ones available in the system. In the case of PCI add-on cards, the BIOS
automatically assigns an IRQ card to the PCI slot the card is installed in.

Overview
7
DMA Channels of ISA Cards
Some Legacy and PnP ISA add-on cards may also need to use a Direct Memory
Access (DMA) channel. DMA assignments for this mainboard are handled in
the same way as the IRQ assignment process outlined above. For more
information, please refer to Chapter 3 of this manual.
Enhanced IDE
This mainboard features an integrated Enhanced IDE controller that provides
convenient, high-speed connections with up to four IDE devices, such as Hard
Disk, CD-ROM and Tape Backup Drives. Enhanced IDE is an upgrade of the
original IDE specification and provides increased capabilities and performance
in a number of areas, including support for Hard Disk Drives of over 1.2GB
and faster data transfer rates utilizing the PIO Mode 4 timing scheme.
With the integrated IDE controller you can connect up to four IDE peripheral
devices to your system. All devices are categorized in the same way that IDE
Hard Disks were configured in the past, with one device set as the Master
device and the other as the Slave device. We recommend that Hard Disk Drives
use the Primary IDE connector and that CD-ROM drives utilize the Secondary
IDE connector for improved system performance.

PA-2006 Mainboard Manual

Serial Infrared (SIR) Connections
This mainboard features support for highly-sophisticated SIR technology,
which allows bi-directional and cordless data transactions with other IrDA
compliant computers and peripheral devices using infrared as a medium. This
transmission is carried out in either Full Duplex Mode or Half Duplex Mode.
The former allows simultaneous data transmission and reception, while the
latter disables the reception when transmission occurs.
The I/O chipset on this mainboard features a SIR interface that is fully
compliant with the IrDA standard. An IrDA device can be installed via a 9-pin
D-SUB connector in the rear panel of the computer which is linked by a cable
to the onboard IrDA pinhead, as shown in the illustration below.
The serial port COM2 on this mainboard is designed to be a SIR compliant
port. If you wish to install the SIR connection feature, you need to adjust the
BIOS option for high-speed performance.

Overview
9
Highly Convenient Integrated I/O Connectors
This mainboard features has an integrated rear I/O panel that incorporates a
full set of I/O ports to allow simple and convenient connections to a complete
selection of external peripheral devices.
In addition to two 16550A UART compatible serial ports and one EPP/ECP
capable parallel port, the panel features two USB connectors that provide high
speed connection to the next generation of USB devices. PS/2 keyboard and
PS/2 mouse connectors provide additional I/O connectivity.
NOTE : USB Feature is reserved for future upgrade.

1). Set System Jumpers
Jumpers
Jumpers are used to select the operation modes for your system. Some jumpers
on the board have three metal pins with each pin representing a different
function. To set a jumper, a black cap containing metal contacts is placed over
the jumper pin/s according to the required configuration. A jumper is said to be
shorted when the black cap has been placed on one or two of its pins. The types
of jumpers used in this manual are shown below:
NOTE : Users are not encouraged to change the jumper settings not listed in
this manual. Changing the jumper settings improperly may adversely affect
