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
www.aopen.com
for detail information.

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
according to user’s settings 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

DDRAM utilizes the existing SDRAM infrastructure and technology while doubling the nominal bandwidth available to systems. To put it in a
simple way, DDRAM 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 up to 266MHz. (2x133=266). And DDR333 (PC2700) is running at
333MHz. 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 for DDR 333 (PC2700).

S/PDIF (Sony/Philips Digital Interface) is a latest audio transfer file format that provides impressive quality through optical fiber and allows
you to enjoy digital audio instead of analog. Normally there are two S/PDIF outputs as shown, one for RCA connector, the most common
one used for consumer audio products, and the other for optical connector with a even better audio quality. Through a specific audio cable,
you can connect the S/PDIF connector to a S/PDIF audio module bearing S/PDIF digital output. However, you must have a S/PDIF
supported speaker with S/PDIF digital input to make the most of this function.

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, AX45-4D Max 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.
Note: This diagram for example only, it may not be exactly the same as the motherboard you purchased.

For high frequency operation, especially when
overclocking, layout is the most important factor to
make sure both chipset and CPU are working in
stable condition. The layout of this motherboard
implements AOpen’s unique design called “Frequency
Isolation Wall”. Separating each critical portion of
motherboard into regions, where each region
operates in a same or similar frequency range, we
can 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 trace must be equal to length
(not necessarily as short as possible) so that clock
skew will be controlled within few a pico second

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
change your Vivid BIOS screen or to download your favorite Open JukeBox skin. If you see this little logo

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 they could.
But at the same time, we believe that same users are affected terribly by the irritating noises of these fans while working with their
PC. 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 not only reduces the noise,
but also consumes the least power the
system needs, so as to prevent over-wasting
of energy resource.
Today, AOpen Motherboard is honored to
bring you a new overall solution, SilentTek, to
make 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 among noises, system
performance and stability.

The following page is surely the most important part of this utility. You may control the rotation speed of specific fans that you have got the
options inside in this page.
1. Smart FAN Control: This is the default setting o
SilentTek and can be used for any branded compute
housing. With a special algorithm developed by AOpen,
the fan speed is automatically adjusted by the factors o
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 that this setting fits you best.
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
CD-ROM Rotation Speed Control: by enabling the CD-ROM
Rotation Speed Control, you can adjust the rotation speed of your
CD-ROM. When you set the speed to high level, the CD-ROM will
work at its fastest speed and it will run at basic required speed
while you set the value to low speed.

fan would remain still when CPU is not fully utilized.
Note: Due to hundreds different brands of fan on the
market, inaccuracy may happen in some cases when you
had your rotation speed adjusted. It is still under the
criterion and please rest assured that it won’t cause any
roblem to your system.

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.

the applications before you start the upgrading.
1. Download the new version of BIOS package zip
2. Unzip the download BIOS package (ex: WAX454DM102.ZIP) with WinZip (http://www.winzip.com
3. Save the unzipped files into a folder, for example, WAX454DM102.EXE & WAX454DM102.BIN.
4. Double click on the WAX454DM102.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.

As a leading manufacturer in motherboard industry, AOpen always listens to what customers want and develop products to fit different
user's requirements. Reliability, compatibility, leading technology and friendly features are our basic goals when designing motherboards.
Other than above mentioned design criteria, there are power users who are always seeking to push the limitation of the system
performance by overclocking which we call them "Overclocker".
This section is dedicated to overclockers.
This high performance motherboard is designed for maximum 400/533MHz CPU bus clock. But it comes with clock generator of 992MHz
(248MHz x4) when we design it to accommodate with future CPU bus clock. Not only that, the CPU clock ratio can be up to 24x that
supports almost all of Pentium
But not guaranty. ☺
Tip: Note that overclocking may also
cause thermal problem. Please make
sure that the cooling fan and the heatsink
were adequate to dissipate excessive
heat that's generated by overclocking the
CPU.
☺

4 CPUs in the future and provides flexibility for overclockers.
Warning: The design of this product follows CPU and chipset vendor's design
guideline. Any attempts to push beyond product specification are not
recommended and you are taking your own risk to damage your system or
important data. Before doing overclocking, you must make sure your
components are able to tolerate such abnormal setting, especially CPU,
DRAMs, hard disks, and AGP VGA cards.

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
Windows 98). This is a bit similar as the PnP
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 to operating system (such as
register interface. ACPI defines ATX momentary soft power switch to control the power state

AAMMRR ((AAuuddiioo//MMooddeemm RRiisseerr))
The CODEC circuit of AC97 sound/modem solution can be put on motherboard or put on a riser card (AMR card) that connects to
motherboard through AMR connector.

A disc bundled with AOpen motherboard product; there are motherboard drivers, Acrobat Reader for PDF online manual and other useful
utilities.
AAPPMM ((AAddvvaanncceedd PPoowweerr MMaannaaggeemmeenntt))
Unlike ACPI, BIOS controls most APM power management functions. AOpen Suspend to Hard Drive is a good example of APM power
management.
AATTAA ((AATT AAttttaacchhmmeenntt))
ATA is the specification of diskette interface. In 80’s, many software and hardware manufacturers instituted the ATA specification together.
The AT is meaning International Business Machines Corporation (IBM) personal computer/AT’s bus structure.
AATTAA//6666
ATA/66 uses both rising edge and falling edge but doubles UDMA/33 transfer rate. The data transfer rate is 4 times of the PIO mode 4 or
DMA mode 2, 16.6MB/s x4 = 66MB/s. To use ATA/66, you need special ATA/66 IDE cable.

AAXX4455--44DD MMaaxx OOnnlliinnee MMaannuuaall
AATTAA//110000
ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as ATA/66 but clock cycle time is
reduced to 40ns. The data transfer rate is (1/40ns) x 2 bytes x 2 = 100MB/s. To use ATA/100, you need special 80-wire IDE cable, the same
as ATA/66.
BBIIOOSS ((BBaassiicc IInnppuutt//OOuuttppuutt SSyysstteemm))
BIOS is a set of assembly routine/program that reside in EPROM or Flash ROM. BIOS controls Input/output devices and other hardware
devices of motherboard. In general, to provide hardware independent portability, operation system and drivers is required to access BIOS
without directly access hardware devices.
BBuuss MMaasstteerr IIDDEE ((DDMMAA mmooddee))
The traditional PIO (Programmable I/O) IDE requires the CPU to involve in all the activities of the IDE access including waiting for the
mechanical events. To reduce the workload of the CPU, the bus master IDE device transfers data from/to memory without interrupting CPU,
and releases CPU to operate concurrently while data is transferring between memory and IDE device. You need the bus master IDE driver
and the bus master IDE HDD to support bus master IDE mode.
CCNNRR ((CCoommmmuunniiccaattiioonn aanndd NNeettwwoorrkkiinngg RRiisseerr))
The CNR specification provides the PC industry the opportunity to deliver a flexible and cost reduced method of implementing LAN, home
networking, DSL, USB, wireless, audio and modem subsystems widely used in today's "connected PCs". The CNR specification is an open
industry specification and is supported by OEMs, IHV card manufacturers, silicon supplier and Microsoft.
