Thank you for your purchasing of MEGA 651, the Best of Computing &

Home Entertainment. Based on the design idea of consumer product, the MEGA
651 is not just a PC anymore. The “All-in-One” feature positions MEGA 651 as a
Digital Media Platform.

From the recent years, the ownership and usage of desktop and notebook

PCs across W.W. households has turned computers into a commodity item. While
Microsoft strongly promotes the “Media Center” platform concept “Windows XP
Media Center Edition” on HP “Free Style”, Intel is also exploring their “Digital
Home” concept for the “Home-use” PC.

To meet the new concept of Home PC, the MEGA 651 has been posi-

tioned as a Digital Media Platform to perform TV-recording (optional), home
theater (DVD+5.1 channels), digital audio playback (MP3, Audio CD), photo and
video stream data browsing. Meanwhile, it can also support high game perfor­mance (AGP 4x slot). On the other hand, the remote controller allows you to use
it like an advanced Hi-Fi stereo in playing CD/MP3 and listening to radio.

An innovative feature to implement the

Hi-Fi stereo into home PC with a fancy

equalizer LCM and control panel on the

front bezel

Introduction

1.1 All-in-one Feature Set

The MEGA651 implements all the Hi-Fi Stereo into Home-PC with a fancy

equalizer LCM and control panel in the front bezel. When PC is power off, you
can use it just like a Hi-Fi Stereo with a remote controller. When PC is power
on, you can use it for Home Theater and Media Center PC. The all-in-one feature
provides you with multiple functions in a small form factor. It can be set any­where you want, such as bedroom or living room, while it’s easily be moved to
anywhere whenever you need.

See the following for the feature:

- Hi-Fi Stereo: Audio CD+ MP3 Player+ AM/FM Tuner (power off)

- Home Theater: DVD+ 5.1 Channel

- Media Center: A/V Browsing/Radio Turning (Card Reader+

SRS

MEGA651 is equipped with SRS audio enforce­ment technology. SRS (Sound Retrieval System) was
the first generation of 3D sound, dramatically improv­ing the quality of standard stereo. SRS is based on the
human hearing system and was designed to retrieve
the natural spatial cues and ambient information that
is present in audio but masked by traditional record­ing and playback methods.

Whether the signal is mono or stereo, SRS ex­pands the audio material to create a realistic three­dimensional sound image. SRS has no sweet-spot and
fills the room with a sound experience much closer to
that of a live performance.

SRS is a trademark of SRS Labs, Inc. SRS tech­nology is incorporated under license from SRS Labs,
Inc.

1.5 Home Theater

Except the general PC function, the MEGA651 has the extra Home The-

ater function when PC button is pressed on.

When PC button is pressed on, you can use the equipped optical drive to
play DVD. The equipped 5.1 channel audio effect gives you a wonderful feeling
of home theater while playing DVD.

Plus, the OPTIONAL MS-8606 TV-Tuner card allows you to watch TV.
The top part of remote controller is designed specially for the TV-Tuner function.
For more informaiton on MS-8606 TV Tuner card, please refer to the maual
packed in MS-8606. After inserting the TV Tuner card, remember to install the
driver packed in CD to using the function.

Introducing Mainboard

2.2 CPU/memory

The MEGA651 supports Intel® Pentium® 4 processors in the 478-pin
package. The mainboard uses a CPU socket called PGA478 for easy CPU
installation. When you are installing the CPU, make sure the CPU has a heat sink
and a cooling fan attached on the top to prevent overheating.

The mainboard provides 2 slots for 184-pin DDR SDRAM DIMM (Double
In-Line Memory Module) modules and supports the memory size up to 2GB. You
can install PC2700/DDR333 or PC2100/DDR266 modules into the DDR DIMM
slots (CN28/26).

Overheating

Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.

Introduction to DDR SDRAM

DDR (Double Data Rate) SDRAM is
similar to conventional SDRAM, but
doubles the rate by transferring data twice
per cycle. It uses 2.5 volts as opposed to 3.
3 volts used in SDR SDRAM, and requires
184-pin DIMM modules rather than 168­pin DIMM modules used by SDR SDRAM.
High memory bandwidth makes DDR an
ideal solution for high performance PC,
workstations and servers.

life time for at least 5 years. If you want to clear the system configuration, use the
JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions below to clear
the data:

You can clear CMOS by shorting 2-3 pin while the
system is off. Then return to 1-2 pin position. Avoid
clearing the CMOS while the system is on; it will dam­age the mainboard.

The AGP slot allows you to insert the AGP graphics
card. AGP is an interface specification designed for the
throughput demands of 3D graphics. It introduces a 66MHz,
32-bit channel for the graphics controller to directly access
main memory and provides three levels of throughputs: 1x
(266Mbps), 2x (533Mbps) and 4x (1.07Gbps).

PCI Slot

The PCI slot allows you to insert PCI card or TV Tuner
card. The TV Tuner card is included in the MEGA651.

When adding or removing expansion cards, make sure
that you unplug the power supply first. Meanwhile, read the
documentation for the expansion card to make any neces­sary hardware or software settings

NOTE: You can insert the OPTIONAL MS8606 card into the
PCI slot to enjoy watching TV.

The MEGA 651 is featured with audio function. There are
two ways to use audio function: in PC mode, in Hi-Fi mode. As
the Mega 651 is shipped out in barebone, you must install the
necessary components (such as HDD, CPU, RAM...) before us­ing audio function in PC mode. However, there is no limit to
use audio function in Hi-Fi mode, although the system is not set
up completely.

You can use control panel or remote controller to select
the audio function in Hi-Fi mode. However, you can also use

the control panel or remote control to select the audio function
in PC mode. See 3.1 and 3.2 for information on control panel

and remote controller. On the other hand, the “Mega Radio”
software has been included in package which allows you to
listen to the radio in PC mode. See Appendix for information on
“Mega Radio”.

In this chapter, we will tell you how to use audio function
in Hi-Fi and PC mode. The LCM pictures are used to provide the
information step by step.

Option Description

Setup The password prompt appears only when end users try

to run Setup.

System A password prompt appears every time when the com-

puter is powered on or when end users try to run Setup.

HDD S.M.A.R.T Capability

This allows you to activate the S.M.A.R.T. (Self-Monitoring Analysis & Reporting
Technology) capability for the hard disks. S.M.A.R.T is a utility that monitors your
disk status to predict hard disk failure. This gives you an opportunity to move
data from a hard disk that is going to fail to a safe place before the hard disk
becomes offline. Settings: Enabled and Disabled.

HT CPU Function

The Intel processor uses Hyper-Threading technology to increase transaction rates
and reduces end-user response times. The technology treats the two cores inside
the processor as two logical processors that can execute instructions
simultaneously. In this way, the system performance is highly improved. If you
disable the function, the processor will use only one core to execute the
instructions. Settings: Enabled and Disabled.

APIC Mode

This field is used to enable or disable the APIC (Advanced Programmable Inter­rupt Controller). Due to compliance with PC2001 design guide, the system is

CAS Latency Setting

The option lets you override the SPD timing to control the CAS latency, which
determines the timing delay before SDRAM starts a read command after receiv­ing it. Settings: 2 Clocks, 2.5 Clocks, 3 Clocks and Disabled. 2 Clocks increases
system performance while 3 Clocks provides more stable system performance.

This option allows you to enable/disable the feature of auto detecting the clock

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes) of
the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum func­tion reduces the EMI generated by modulating the pulses so that the spikes of the
pulses are reduced to flatter curves. If you do not have any EMI problem, leave
the setting at Disabled for optimal system stability and performance. But if you
are plagued by EMI, activate the Spread Spectrum for EMI reduction. Remember
to disable Spread Spectrum if you are overclocking because even a slight jitter
can introduce a temporary boost in clockspeed which may just cause your
