3.3 Install Memory Modules
The motherboard has three Dual Inline Memory Module (DIMM)
sockets and supports the maximum memory size up to 512MB.
These DIMM sockets only support 3.3V unbuffered SDRAM
modules of 16M, 64M, 128M and 256M. The motherboard also
support SPD (Serial Presence Detect) architecture to provide the
best choice for performance vs. stability.

3.5 CNR
The interface of Communication and Networking Riser(CNR)
supports the audio, modem, and local area network(LAN).
Motherboard integration of the audio, modem, and LAN subsystems
is also problematic, due to the potential for incease noise, which inturn degrades the performance of each system. The CNR
specifically addresses these problems by physical separating these
noise-sensitive systems from the noisy environment of the
motherboard.

4.1 PhoenixNet Introduction
PhoenixNet is a service that provides PC users with best-of-breed,
free, software services to support their PC hardware and software
and to turn their computer into a powerful tool for communication,
entertainment, education and business
4.1.1Internet Launch System
The PhoenixNet Internet Launch System (ILS) is a patentpending technology built into the firmware to enable online
PC users worldwide to communicate with PhoenixNet and to
receive the free PhoenixNet services. ILS resides safely
within ROM and is activated the first time a user launches a
PhoenixNet-enabled PC with a Windows 98 Operating
System.
4.1.2PhoenixNet Online Services
When the PhoenixNet ILS detects an Internet connection, it
makes contact with the PhoenixNet server and delivers userselectable services from PhoenixNet’s Internet Partners.
These services are delivered to the user as hotlinks on the
desktop and in the web browser or, as applications that
PhoenixNet automatically packages, downloads and
installs.

4.2.1Upgrade BIOS
The BIOS can be upgraded from a diskette with the Award
Flash utility — AWDFLASH.EXE. The BIOS image file, and
update utility are available from IWILL ’ s WEB site: www.
iwill.net
4.2.2Enter BIOS setup program
Power-on the system by either pressing the Power-On
button, or by using any of the power-on features provided by
the motherboard. Then, press the <Del> key after the PowerOn Self Test (POST), and before the scanning of IDE devices.
Simply look for the message “Press DEL to enter SETUP”
displayed at the bottom of the screen during the boot up
process. If the message disappears before you’ve had a
chance to respond, you can restart the system by
Turning off the system power then turn it on again, or
Pressing the “RESET” button on the system case, or
Pressing <Ctrl>, <Alt> and <Del> keys simultaneously.

If the system is no longer able to boot after changing the settings,
the only way to recover it is to clear the data stored in RTC CMOS.
To reset the RTC CMOS data, take the JP1 jumper cap off pins 1-2,
place onto pins 2-3, and then place back onto pins 1-2 again. This
will return the RTC to the default setting. Then, get into the BIOS
setup program , choose Load Fail-Safe Defaults ; Load Optimized

Afterwards, if necessary, you can run an anti-virus program to
locate and remove the problem before any damage is done.
Many disk diagnostic programs will attempt to access the

you first disable the Virus Warning function beforehand.

The first chipset settings deal with CPU access to dynamic
random access memory (DRAM). The default timings have

might result, however this preserves the integrity of the data

4.1 1.1 Iwill MicroStepping
MicroStepping
Microstepping is Iwill's anther step forward to provides users
a fuss free CPU frequency set up procedure. It contains two
main functions, Auto Detecting CPUs speed and Micro
Adjustable CPU FSB speed.
Auto Detecting CPU speed:
IWILL MicroStepping will auto detect the CPU's factory
multiplier setting and CPU FSB to the factory default. This
function provides a "fuss free" CPU set up process for the
general users.
Micro Adjustable CPU FSB speed:
IWILL provides a user friendly overclocking function that
allows users to experience the fun of overclocking. This
function allows user to adjust CPU FSB by 1MHz interval.
This is particularly useful when user wants to extract the
most out of the purchased CPU. For example: you select
from 133, 134, 135, 136, 137,138MHz and up to the
maximum speed that the system can sustained.
In the time should overclocking failed, MicroStepping will auto
detects the CPU's factory multiplier setting and set the CPU
FSB to default 66MHz, to protect the CPU installed.

5.3.7The 4 Speakers System
The on board audio on Iwill motherboards provide 2 wave
channels (front/rear + subwoffer), known as the 4.1 speakers
system. When games or application programs via
DirectSound® 3D or A3D® interface locate the sound
sources to the listener’s back, the two rear speakers will
work to enhance the rear audio positional effect, so as to
complement the insufficiency of using only two front speakers
to emulate the audio effect. The following is the hardware
installation and the software setups:
6.3.7.1 The speaker installation.
Connect the front pair speakers to the Line-out jack of
the audio adapter, and then connect rear pair
speakers to Line-in/Rear jack of the audio adapter.

the mixer, and when you enable this option, it means
the rear speakers are connected to Line-in/Rear jack.
When Line-in/Rear jack is connected to other
external Line-in sources, please DO NOT enable this
option in order to avoid hardware conflicts. Regarding
rear speaker option, you can turn on or turn off the
output of the back speakers, and adjust the volume,
to have the rear/front speakers have the same
volume.
