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 is stored 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.

Overview

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.

PA-2005 Mainboard Manual
10
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 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.

Overview
11
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-type 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.

PA-2005 Mainboard Manual
12
Universal Serial Bus (USB) Functionality
This mainboard features integrated support for state-of-the-art USB
technology, which provides high-speed and easy-to-use Plug & Play
connections to the future generation of external peripherals, such as keyboards,
mouse, monitors, game devices, scanners, printers, and fax/modems.
USB overcomes conventional I/O bottlenecks by combining the I/O ports into
a single dual-channel connector. For optimum ease of use and flexibility, USB
not only allows the automatic detection and configuration of peripherals after
installation, but also enables the simultaneous connection.
This mainboard features an optional USB connector bracket that is connected
by a cable to the onboard USB pinhead. The bracket can be installed in one of
the I/O expansion slots on the rear panel of the system, as shown in the
illustration below. It provides fast and convenient Plug and Play peripheral
connections outside your computer, allowing you take full advantage of the
universal functionality and flexibility of USB technology.
