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

AOpen provides a special and useful feature on this motherboard for overclockers. When you

power-on the system, the BIOS will check last system POST

enable “Watch Dog Timer” function immediately, and set the CPU FSB

settings stored in the BIOS. If system failed in BIOS POST, the “Watch Dog ABS” will reset the system

to reboot in five seconds. Then, BIOS will detect the CPU’s default frequency and POST again. With this special feature, you can easily

overclock your system to get a higher system performance without removing the system housing and save the hassle from setting the

jumper to clear CMOS data when system hangs.

DDR SDRAM utilizes the existing SDRAM infrastructure and technology while doubling the nominal bandwidth available to systems. To put

it in a simple way, DDR SDRAM is like data going along a two lane highway, while at the same time data in traditional SDRAM go along a

one way street. Therefore, it is a more advanced technology that provides a great overall improvement in system performance. DDR266

(PC2100) runs two times faster than the traditional PC133 SDRAM with the speed of Front Side Bus (FSB) up to 266MHz. (2x133=266).

And DDR333 (PC2700) is running at 333MHz FSB. Both PC2100 and PC2700 are a new naming standard for speed of DDR 266 and

DDR 333, representing their theoretical speeds of the RAM. The theoretical transfer rate of DDR 266 (PC2100) is 2.1GB/s and 2.7GB/s is

This motherboard supports ATA66 , ATA100 or ATA133 IDE devices. Following table lists the transfer rate of IDE PIO and DMA modes. The IDE bus is 16-bit, which means every transfer is two bytes. As the hard drive industry introduces faster and higher capacity hard drives, the current Ultra ATA/100 interface causes a data bottleneck between the drive and the host computer. To avoid this problem, hard disk manufactures have introduced the new Ultra ATA-133 interface technology. percent increase in interface speed with transfer rate of 133MB/s. ATA/133 performance is ideal for new operating systems, such as Window XP, that demand more storage space and faster data transfer rates from more responsive computing experiences.

To make good use of this new technology and enjoy its best performance, we recommend you to pair your system with a hard disk equipped with ATA/133 technology so that your system's need for speed on this motherboard can be satisfied.

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.

The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for the stability of

CPU power. The idea of where to put these capacitors is another know-how that requires experience and detail calculation.

Not only that, AX45-8X / AX45-8XN implements 2200μF capacitors, which is much larger than normal capacitor (1000 & 1500μf) and it

provides better stability for CPU power.

The power circuit of the CPU core voltage must be checked to ensure system stability for high speed CPUs (such as the new Pentium III, or

when overclocking). A typical CPU core voltage is 2.0V, so a good design should control voltage between 1.860V and 2.140V. That is, the

transient must be below 280mV. Below is a timing diagram captured by a Digital Storage Scope, it shows the voltage transient is only

143mv even when maximum 60A current is applied.

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 colors 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

dynamic-showing GIF animation.

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.

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

the rapid developing of AGP card, we can see that it had been developed from single colorful AGP card to 2D and 3D 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.

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 DMA. AT A 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

Traditional motherboard stores BIOS code in EPROM. EPROM can only be erased by ultra-violet (UV) light. If BIOS has to be upgraded,

you need to remove EPROM from motherboard, clear by UV light, re-program, and then insert back.

EEVV66 BBuus

EV6 Bus is the technology of Alpha processor from Digital Equipment Corporation. EV6 bus uses both rising and falling clock edge to

transfer data, similar as DDR RAM or ATA/66 IDE bus.

EV6 Bus Speed = CPU external bus clock x 2.

200 MHz EV6 bus, 200MHz = 100 MHz external bus clock x 2

by virus. Because of increase of new functions, BIOS size is increased from 64KB to 512KB (4M bit).

HHyyppeerr TThhrreeaaddiinng

Hyper-Threading technology is an innovative design from Intel that enables multi-threaded software applications to process threads in

parallel within each processor resulting in increased utilization of processor execution resources. As a result, an average 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 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.
