Chapter 1: Product introduction

Gigabit LAN solution

The Intel® 82547GI Gigabit Ethernet controller allows full-duplex Gigabit
performance on LAN on Motherboard (LOM) applications through the
Communication Streaming Architecture (CSA). Instead of connecting to
the PCI bus, the controller connects to the dedicated CSA bus on the
Memory Controller Hub (MCH) thus reducing the PCI bottlenecks by
freeing the PCI bus for other I/O operations.

AGP 8X support

The motherboard supports the latest graphic architecture, the AGP Pro/8X
interface (a.k.a. AGP 3.0), offering 2.1GB/s bandwidth which is twice that
of its predecessor AGP 4X.

IEEE 1394 support

The IEEE 1394 interfaces and the TI TSB43AB22A controller onboard
provide high-speed and flexible PC connectivity to a wide range of
peripherals and devices compliant to IEEE 1394a standards. The IEEE
1394 allows up to 400Mbps transfer rates through simple, low-cost, high­bandwidth asynchronous (real-time) data interfacing between computers,
peripherals, and consumer electronic devices such as camcorders, VCRs,
printers,TVs, and digital cameras.

6-channel audio feature

The SoundMAX-class ADI AD1980 AC ‘97 audio CODEC supports
6-channel 5.1 surround sound output, stereo microphone input, variable
Sample Rate Conversion (SRC), professional quality 103-dB out put with
94-dB Signal Noise Ratio (SNR), and analog enumeration capability. The
SoundMAX 4 XL software features the AudioESP™ (Audio Enumeration
and Sensing Process) that allows intelligent detection of the peripherals
plugged into the audio ports and identifies the incompatible devices, if any.

ASUS POST Reporter™

The motherboard offers a new exciting feature called the ASUS POST
Reporter™ to provide friendly voice messages and alerts during the
Power-On Self-Tests (POST) informing you of the system boot status and
causes of boot errors, if any. The bundled Winbond Voice Editor software
lets you customize the voice messages in the supported languages.

ASUS NCCH-DL motherboard

1-3

ASUS Q-Fan technology

The ASUS Q-Fan technology smartly adjusts the fan speeds according to
the system loading to ensure quiet, cool, and efficient operation.

80 Pins104 Pins

2.4.2 Memory configurations

You may install unbuffered ECC or non-ECC 64MB, 128MB, 256MB,
512MB, and 1GB DDR DIMMs into the DIMM sockets using the
recommended memory configurations.

Important notes

1. Installing DDR DIMMs other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of
the recommended configurations in Table 1.

2. In dual-channel configurations, install only identical (the same
type and size) DDR DIMM pairs for each channel.

3. Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor.

4. Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to Table 2.

5. DIMMs installed into any three sockets will function in single-
channel mode.

6. When all four sockets are populated with 1GB DIMMs (total 4GB),
the system may detect only about 3.6+ GB (less than 4 GB) due to
resource allocation of onboard devices.

4.1.3 ASUS EZ Flash Utility

he ASUS EZ Flash feature allows you to update the BIOS without having
to go through the long process of booting from a floppy disk and using a
DOS-based utility. The EZ Flash utility is built-in the BIOS chip so it is
accessible by pressing <Alt> + <F2> during the Power-On Self Tests
(POST).

To update the BIOS using EZ Flash:

1. Visit the ASUS website (www.asus.com) to download the latest BIOS
file for the motherboard and rename the same to P5AD2.ROM.

2. Save the BIOS file to a floppy disk, then restart the system.

3. Press <Alt> + <F2> during POST to display the following.

EZFlash starting BIOS update
Checking for floppy...

4. Insert the floppy disk that contains the BIOS file to the floppy disk
drive. When the correct BIOS file is found, EZ Flash performs the BIOS
update process and automatically reboots the system when done.

A “Floppy not found!” error message appears if there is no floppy disk
in the drive. A “NCCH-DL.ROM not found!” error message appears if
the correct BIOS file is not found in the floppy disk. Make sure that you
rename the BIOS file to NCCH-DL.ROM.

Chapter 4: BIOS Setup

4.2 BIOS Setup program

This motherboard includes a Flash ROM that you can update using the
provided utility described in section “4.1 Managing and updating your
BIOS.”

Use the BIOS Setup program when you are installing a motherboard,
reconfiguring your system, or prompted to “Run Setup”. This section
explains how to configure your system using this utility.

Even if you are not prompted to use the Setup program, you may want to
change the configuration of your computer in the future. For example, you
may want to enable the security password feature or make changes to the
power management settings. This requires you to reconfigure your system
using the BIOS Setup program so that the computer can recognize these
changes and record them in the CMOS RAM of the Flash ROM.

The Flash ROM on the motherboard stores the Setup utility. When you
start up the computer, the system provides you with the opportunity to run
this program. Press <Delete> during the Power-On Self Test (POST) to
enter the Setup utility, otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing
<Ctrl> + <Alt> + <Delete>, or by pressing the reset button on the system
chassis. You can also restart by turning the system off and then back on.
Do this last option only if the first two failed.

The Setup program is designed to make it as easy to use as possible. It is
a menu-driven program, which means you can scroll through the various
sub-menus and make your selections among the predetermined choices.

Because the BIOS software is constantly being updated, the following
BIOS setup screens and descriptions are for reference purposes only,
and may not exactly match what you see on your screen.
