When you read this online manual and start to assemble your computer system, you may notice that some of the functions are marked as

“User Upgrade Optional” or “Manufacture Upgrade Optional”. Although all of AOpen’s motherboards have included many amazing and

powerful features, sometimes not every user is familiar with these powerful features. As a result of this we define features that can be

upgraded by users as “User Upgrade Optional”. You can upgrade these functions by purchasing additional devices. As for functions that

cannot be upgraded by users, we define them as “Manufacture Upgrade Optional”. If need be, you can contact our local distributors or

resellers to purchase “Manufacture Upgrade Optional” components, and again you are also welcome to visit our official website at

The Over Current Protection is a popular implementation on ATX 3.3V/5V/12V switching power supply. However, the new generation CPU

uses different voltage with a regulator to transfer 12V to CPU voltage (for example, 2.0V), and thus makes 5V over current protection

useless. This motherboard is with switching regulator onboard supporting CPU over-current protection; in conjunction with 3.3V/5V/12V

power supply provide the full line over-current protection.

Note: Although we have implemented protection circuit and tried to prevent any human operating

mistake, certain risks might still happen when CPU, memory, HDD or add-on cards installed on this

motherboard is damaged due to component failure, human operating error or other unknown natural

reasons. AOpen cannot guarantee that the protection circuit will always work perfectly.

IDE1 is also known as the primary channel and IDE2 as the secondary channel. Each channel supports two IDE devices that make a total

of four devices. In order to work together, the two devices on each channel must be set differently to Master and Slave mode. Either one

can be the hard disk or the CDROM. The setting as master or slave mode depends on the jumper on your IDE device, so please refer to

your hard disk and CDROM manual accordingly.

Tip:

Intel ICH5 integrates two Serial ATA host controllers that provide you an even faster transfer rate of 150

Mbytes/second. The traditional parallel ATA specification has defined the standard storage interface for PCs

with its original speed of just 3 Mbytes/second since the protocol was introduced in the 1980s. And the latest

generation of the interface, Ultra ATA-133, has been developed further with a burst data transfer rate of 133

Mbytes/second. However, while ATA has enjoyed an illustrious track record, the specification is now showing its age and imposes some

serious design issues on today’s developers, including a 5-volt signaling requirement, high pin count, and serious cabling headaches.

The Serial ATA specification is designed to overcome these design limitations while enabling the storage interface to scale with the growing

media rate demands of PC platforms. Serial ATA is to replace parallel ATA with the compatibility with existing operating systems and drivers,

adding performance headroom for years to come. It reduces voltage and pins count requirements and can be implemented with thin and

easy to route cables.

Note: Please note that only under

Windows XP and Windows.Net

environment can you install the

total of 2 Parallel ATA and 2 Serial

TA disks.

To connect a Serial ATA disk, you have to have a 7-pin Serial ATA cable. Connect two ends of the Serial ATA cable to the Serial ATA header

on the motherboard and the disk. Like every other traditional disk, you also have to connect a power cable. Please note that it is a jumper

free implement; you don’t need to set jumpers to define a master or slave disk. When connecting two Serial ATA disks, the system will

automatically take the one connected to “Serial ATA 1” header as a master disk.

Except its original 2 sets of parallel IDE, this motherboard also supports the latest Serial ATA hard disk. If you are unable to find your newly

installed Serial ATA hard disks on your operating system after you install them, the problem mainly lies in the BIOS setting. You can simply

adjust BIOS settings to have them work properly.

After having properly installed your hard disks, you can directly go to the BIOS setting screen for adjustment. Simply choosing “Integrated

Peripherals  OnChip IDE Device  On-Chip Serial ATA”, you can set your preferable mode. If you have no intention to change its original

setting, the default setting is Auto.

Page 37

MMXX44SSGG--NN // MMXX44SSGG--LL OOnnlliinnee MMaannuuaall

If you intend to change the default setting, simply press Enter for a list of selection:

1. Disabled: You may choose this item if you’re sure that only traditional IDE hard

disks are installed on your system. Disabling this item may also cancel the detection

to Serial ATA hard disk during POST, which theoretically, could speed up your

boot-up timing a bit; however, please remember to re-adjust the settings here if you

intend to use Serial ATA hard disk later.

2. Auto: This is the factory default setting of your motherboard. Basically, if your

system works properly, it’s not necessary to change it. The system will automatically

recognize the first hard disk on IDE1 as the first boot device.

Note: Please be informed that when you are using Windows98/ME with six hard

disks fully installed, Auto mode will not function properly, it’s just because Windows98/Me cannot recognize Enhanced Mode to detect

all hard disks.

3. Combined Mode: If you install traditional IDE hard disks and Serial ATA hard disks at the same time, then you can choose this

Combined Mode. Under this mode, you may randomly choose either IDE hard disks or Serial ATA had disk as your first boot device.

But please aware that Serial ATA will exist with IDE in a mapping way, which means it will occupy one of the IDE Channel and leave

you with one IDE Channel only.

4. Enhanced Mode: If you use the latest operating system (say, WindowsXP, Windows.NET Server), it is highly recommended that you

set Enhanced Mode. The system is able to detect all six devices (traditional IDE x4, Serial ATA x 2) and functions perfectly under this

mode. But please note that it is defaulted with using traditional IDE as the first boot device.

Note: From our practical lab tests, we found no obvious problem or mistakes happened under Windows2000 operating system, but,

however, it doesn’t confirm to the regulation recommended by Intel.

5. SATA Only: You may select this SATA Only mode if you install Serial ATA hard disks only. It allows you to select booting sequence

from Port0 (SerialATA1) or Port1 (SerialATA2).

With outstanding R&D ability of AOpen, we now bring you a whole new BIOS Flash wizard

---- EzWinFlash. With an eye to users convenience, EzWinFlash combines the BIOS binary

code and flash module together, so the only thing you have to do is just clicking on the utility

you downloaded from web and let it helps you complete the flash process automatically.

EzWinFlash detects your motherboard and checks the BIOS version cleverly to prevent your system from any possible failure. Moreover,

EzWinFlash has been taken into consideration to go with any windows platform you might be using, no matter if you’re using Windows

95/98, 98SE/ME, NT4.0/2000, or even the latest Windows XP.

In the meanwhile, in order to provide a much more user-friendly operating environment, AOpen EzWinFlash is natively designed to have

multi-language function to provide easier way for users’ usage in changing BIOS setting.

Caution: By updating your motherboard,

you are taking a risk of BIOS flash failure. If

your motherboard is working stable, and

there are no major bugs that had been fixed

by a latter BIOS revision, we recommend

that you DO NOT try to upgrade your BIOS.

If you intent on upgrading, PLEASE BE

SURE to get the right BIOS revision for the

right motherboard model to avoid any

ossibility failure.

You may accomplish BIOS upgrade procedure with EzWinFlash by the following steps, and it’s STRONGLY RECOMMENDED to close all

the applications before you start the upgrading.

1. Download the new version of BIOS package zip

2. Unzip the download BIOS package (ex: WMX4SGN102.ZIP) with WinZip (http://www.winzip.com

3. Save the unzipped files into a folder, for example, WMX4SGN102.EXE & WMX4SGN102.BIN.

4. Double click on the WMX4SGN102.EXE, EzWinFlash will detect the model name and BIOS version of your motherboard. If you had

got the wrong BIOS, you will not be allowed to proceed with the flash steps.

5. You may select preferred language in the main menu, then click [Start Flash] to start the BIOS upgrade procedure.

6. EzWinFlash will complete all the process automatically, and a dialogue box will pop up to ask you to restart Windows. You may click

[YES] to reboot Windows.

7. Press <Del> at POST to enter BIOS setup

It is strongly recommended NOT to turn off the power or run any application during FLASH PROCESS.

Warning: The new BIOS upgrade will permanently replace your

original BIOS’s settings when flashing. You may need to reconfigure

your BIOS setting so that your system can go back to work as normal.

Unlike earlier graphic POST screen which could occupy the whole screen and mask text information during POST, AOpen VividBIOS deals

with graphics and texts separately, and makes them running simultaneously during POST. With this innovative design, VividBios now brings

you a beautiful and sleek 256 colours screen without missing any important information shown on POST screen.

In addition, the limited space of BIOS ROM is another big issue. When all of the traditional BIOS can only show space-consuming and

uncompressed Bitmap, AOpen has considerately tuned the BIOS to next generation, to recognize the smaller-sized GIF format and even

AACC9977 CCOODDEECC

Basically, AC97 CODEC is the standard structure of PCI sound card. As we know, computer is digital-based, but music is based on

analog-based. Therefore, there must be a process to turn digital into analog during the last stage processing of sound in computer.

Hence, the component on sound card that play this important task is what we called CODEC.

Audio CODEC 97 (briefly called AC97) is the specification regulated by Intel, and it’s about the structure of audio conversion. The

special place about CODEC is that it is separated from sound card (CODEC is an independent chipset). Therefore, PCI sound card

could possess with 90db and do other application process as well. We called CODEC that meets this structure AC97 CODEC.

AACCPPII ((AAddvvaanncceedd CCoonnffiigguurraattiioonn && PPoowweerr IInntteerrffaaccee)

ACPI is the power management specification of PC97 (1997). It intends to save more power by taking full control of power

The main function of AGP simply put is to tell monitor what screen information had to be shown, a visual transmission device

graphic. AGP supports only memory read/write operation and single-master single-slave one-to-one only. Though AGP and PCI

share the same algorithm of 32-bit, its frequencies are 66MHz and 33MHz respectively. AGP interface had been developed from

2X to 8x.

1X AGP, data transfer rate is 66MHz x 4byte x 1 = 264MB/s

2X AGP, data transfer rate is 66MHz x 4byte x 2 = 528MB/s

4X AGP, data transfer rate is 66MHz x 4byte x 4 = 1056MB/s.

8X AGP, data transfer rate is 66MHz x 4byte x 8 = 2112MB/s.

Before talking about ATA (AT Attachment), we must understand DMA (Direct Memory Access), which allows devices to skip the

CPU devices and access memory directly. DMA specification could not only eliminate the workload of CPU, but also accelerate the

transmission of data. DMA begins with a data transfer rate of 16.6MB/Sec, but afterward developed to new data rate of 33.3MB/Sec,

which is twice the data rate and we called it Ultra DM A. ATA details power and data signals between the drive and integrated

drive controller and the computer's motherboard. Two drives (master and slave) are supported. The ATA specification allows the

drive to connect directly to the ISA bus on the computer. ATA transfer rate then had been developed to 133MHz/Sec and would

come out with fastest rate later (please refer to Serial ATA

DMA, data transfer rate is 16.6MHz/s.

Ultra DM A, data transfer rate is 16.6MHz x 2 = 33MB/s.

ATA/66 , data transfer rate is 16.6MHz x 4 = 66MB/s.

ATA/100, data transfer rate is 16.6MHz x 6 = 100MB/s.

ATA/133, data transfer rate is 16.6MHz x 8 = 133MB/s.

(ATA/133 uses both rising edge and falling edge as ATA/66 but clock cycle time is reduced to 30ns.)

improvement of ~40% in CPU resource utilization yields higher processing throughput.

IIEEEEEE 1133994

IEEE 1394, which also called Firewire, is a serial data transfer protocol and interconnection system. The main feature of the

Firewire that assures its adoption for the digital video and audio (A/V) consumer application is its low cost. Fire wire interface is

Page 93

MMXX44SSGG--NN // MMXX44SSGG--LL OOnnlliinnee MMaannuuaall

capable of supporting various high-end digital A/V applications, such as consumer A/V device control and signal routing, Digital

Video (DV) editing, home networking, and more than 32 channels of digital mixing. Gone are those days of expensive video

capture cards. Firewire allows for video capture from both newer DV camcorders with Firewire ports and older analog equipment

using A/V to Firewire converters.

The advantages of the IEEE1394:

High data transfer rate – Start from 400 Mbps, (with 800/1600/3200 Mbps coming soon), which is about 30 times faster than USB

1.1.

Supports up to 63 devices (16 - daisy chained) with cable length up to about 4.5 m (14 feet).

Hot-pluggable (like USB). No need to turn of your device to connect or disconnect, and you don't need to reboot your PC. Also, it is

a plug-and-play bus.

IEEE1394 is very easy to connect (Like USB1.1/2/0).

PPaarriittyy BBiit

The parity mode uses 1 parity bit for each byte, normally it is even parity mode, that is, each time the memory data is updated,

parity bit will be adjusted to have even count "1" for each byte. When next time, if memory is read with odd number of "1", the parity

error is occurred and this is called single bit error detection.

PPCCII ((PPeerriipphheerraall CCoommppoonneenntt IInntteerrffaaccee)) BBuus

Developed by Intel, Peripheral Component Interconnect (PCI) is a local bus standard. A bus is a channel used to transfer data to

(input) and from (output) a computer and to or from a peripheral device. Most PCs have a PCI bus usually implemented at 32-bits

providing a 33 MHz clock speed with a throughput rate of 133 MBps.

Oversimplified, Plug-and-Play automatically tells the software (device drivers) where to find various pieces of hardware (devices)

such as modems, network cards, sound cards, etc. Plug-and-Play's task is to match up physical devices with the software (device

drivers) that operates them and to establish channels of communication between each physical device and its driver.

SSDDRRAAMM ((SSyynncchhrroonnoouuss DDRRAAMM))

SDRAM is one of the DRAM technologies that allow DRAM to use the same clock as the CPU host bus (EDO and FPM are

asynchronous and do not have clock signal). It is similar as PBSRAM to use burst mode transfer. SDRAM comes in 64-bit 168-pin

DIMM and operates at 3.3V, and have been gradually replaced by DDR RAM.
