When you read this online manual and start to assemble your computer system, you may find some of functions are called

“Manufacturer Upgrade Optional”, and some are called “User Upgrade Optional”. Though all AOpen motherboards include many

amazing and powerful features, in some situations, these powerful features are not used to every user. Hence, we changed

some key features as “Manufacturer Upgrade Optional” for you to choose. Some optional functions that can be upgraded by

users, we call them “User Upgrade Optional”. As for those optional functions that can’t be upgraded by ourselves, we call them

“Manufacturer Upgrade Optional”. If needed, you can contact our local distributors or resellers for purchasing “User Upgrade

Optional” components, and again you can visit AOpen official web site: www.aopen.com

With this motherboard, AOpen provides a very special, useful feature 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

that stored in the BIOS. If system failed in BIOS POST, the “Watch Dog Timer” 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 higher system performance, and without removing

the cover of system housing to set the jumper to clear CMOS data when your system hanged.

This motherboard comes with a Silicon Image Serial ATA (Sil3112ACT144) controller, aiming to 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.

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

be noted 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.

Over Current Protection has been popularly implemented on ATX 3.3V/5V/12V switching power supply for a while. However,

new generation CPU is able to use regulator of different voltages to transfer 12V to CPU voltage (for example, to 2.0V). This

motherboard is with switching regulator onboard that supports CPU over-current protection, and it applies to 3.3V/5V/12V power

supply for providing full line over-current protection.

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, AX4R Plus implements 3300μF capacitors, which is much larger than normal capacitor (1000 and 1500μf ) and it

provides better stability for CPU power.

Separating each critical portion of motherboard into

regions where each region operates in a same or

similar frequency range to avoid cross talk and

frequency interference between each region’s

operations and condition. The trace length and route

must be calculated carefully. For example, the clock

As the clock of CPU keeps rocketing higher and higher, it inevitably brings higher heat and

system temperature in a relative way. The way we deal with this heat problem, however, is to

spare no effort to add one fan after another to protect our pampered system, expecting these

fans could cool down our machine as much as it could.

But at the same time, we believe that same amount of users are affected terribly while working with their PC by the irritating

noises of these fans. As a matter of fact, we do not have to get our fans running at such a high speed in most cases; on the

contrary, we discovered that having your fans

running at appropriate time and speed could not

only reduce the noise, but also consume the least

power the system needed, so as to prevent

over-wasting of energy resource.

Today, AOpen Motherboard is honored to bring you

a new overall solution, SilentTek, to have your

system quiet. To collocate with hardware circuit,

BIOS and the utility under Windows, SilentTek

combined “Hardware-Status Monitoring”, “Overheat

Warning” and “Fan Speed Control” with

user-friendly interfaces to provide you a perfect

balance between noises, system performance and

stability.

Page 76

AAXX44RR PPlluuss OOnnlliinnee MMaannuuaall

The first image you have here is the Voltage Status page. You can find current status of all voltages and set your expected margins of warning level.

You may check you system voltage from the indicating bar here.

In “Temp/Fan/Case” page, you may get aware of the current temperature of CPU and the heat inside chassis, plus checking if fans are running properly.

Of course, you may set you defaulted lowest margin fo your fans and the SilentTek would also pop up a message box and alarm you when the fan is rotating slower than this specified speed.

You may set the highest margin of your CPU and system temperature as default, and SilentTek would pop up a message box and alert you with alarm when the temperature goes beyond the specified margin.

Page 77

AAXX44RR PPlluuss OOnnlliinnee MMaannuuaall

The following page is sure to be the most important part of this utility, you may control the rotation speed of specific fans you got

with options inside in this page. Respectively illustrate as follow:

1. Smart FAN Control: This is the default setting of

SilentTek and can be used for any branded computer

housing. With a special algorithm developed by

AOpen, the fan speed is automatically adjusted by

the factors of CPU and ambient temperature.

Ease-of-use and trouble free at your service.

2. Fixed FAN Control: Under this setting, a desired fan

speed is set fixed when operating.

3. Multiple Level Control: This is the most versatile

setting that allows you to set fan speed in relation to

temperature. You may find this setting fits youbest.

4. AOpen Recommend Setting: This setting is

designed specifically for AOpen housing. A series of

lab tests were conducted under the real world

scenario to determine optimum fan speed to reduce

noise level within CPU working condition and

temperature. Most of the time, the fan would remain

still when CPU is not fully utilized.

Have you been fed up with the conservative and immutable POST screen? Let’s rule out the

tradition idea that POST screen are stiff and frigid, and let AOpen show you the newly

developed VividBIOS to experience the lively vivid colorful POST screen!

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.

Vivid BIOS shares the same fundamental technology with Open JukeBox CD Player, you may use the same EzSkin utility to

AACC9977

Basically, AC97 specification separates sound/modem circuit to two parts, digital processor and a CODEC for analogy I/O they

are linked by AC97 link bus. Since digital processor can be put into motherboard main chipset, the cost of sound/modem

onboard solution can be reduced.

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

management to operating system and bypass BIOS

to operating system (such as Windows 98). This is a bit similar as the PnP

power switch to control the power state transition.

AAGGPP ((AAcccceelleerraatteedd GGrraapphhiicc PPoorrtt))

AGP is a bus interface targeted for high-performance 3D graphic. AGP supports only memory read/write operation and

single-master single-slave one-to-one only. AGP uses both rising and falling edge of the 66MHz clock, for 2X AGP, the data

transfer rate is 66MHz x 4byte x 2 = 528MB/s. AGP is now moving to 4X mode, 66MHz x 4byte x 4 = 1056MB/s. AOpen is the

first company to support 4X AGP motherboards by both AX6C (Intel 820) and MX64/AX64 (VIA 694x), started from Oct 1999.

. The chipset or super I/O chip needs to provide standard register interface
