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 incl uded 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 o r
resellers to purchase “Manufacture Upgrade Optional” components, and again you are also welcome to visit our official website at
www.aopen.com

DDR SDRAM utilizes the existing SDRAM infrastructure and technology while doubling the nominal bandwidth available to systems. To pu t
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. Bot h 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).

IDE bus is 16-bit, which means every transfer is two bytes. As the hard drive indust ry introduces faster and higher capacity hard dri ves,
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 int erface technology.

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 protecti on; 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.
Note: This diagram for example only, it may not be exactly the same as the motherboard you purchased.

Note: This diagram for example only, it may not look exactly the same as the motherboard you

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
Open’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 poss ible) so t hat clock
skew will be controlled within few a pico second (1/10
Sec)

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 desi gn, 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

free space has to be reserved in the disk, e.g. if you have 64 MB DRAM and 16 MB VGA card installed, the system needs at least
80 MB free space. Th e u tili ty will locate the space auto ma tically.
b. If you assign an individual partition for Win 98, please run "aozvhdd /c /partition". Of course, the system needs to provide
unformatted an empty partition.
4. Reboot system.
5. You've already implemented ACPI Suspend to-Hard Drive. Click "Start > Shut Down > Standby" then the screen will go off immediately.
And 1 minute or so will be taken for the system to save what's in the memory to the hard drive; the larger the memory size the longer this
process will take.

This motherboard supports ACPI Suspend to RAM function. With this function, you can resume your original work directly from DRAM
without going through the Windows 98 booting process and run your application again. Suspend to DRAM saves your current work in the
system memory, it is faster than Suspend to Hard Drive but requires power supplied to DRAM, while Suspend to Hard Drive requires no
power.

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 environm ent, 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.

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 533MHz CPU bus clock. But it comes with clock generator of 248MHz 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

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.
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

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 interf ace. In 80’s, many software and hardware manufacturers instituted the ATA specification toget her.
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.
