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

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

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.

AX45-8X Max provides an AGP 8x slot which is the latest AGP specification. The AGP 8x calls for the bus to operate at the basic AGP
66-MHz clock frequency and the bandwidth is 2.1Gbytes/s. It is a great improvement on the performance of 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 4bytes x 2 = 528MB/s and AGP 4x mode, 66MHz x 4bytes x 4 = 1056MB/s. Now the

To use Wake On LAN function, you must have a network card with chipset that supports this feature, and connect a cable from LAN card to
motherboard WOL connector. The system identification information (probably IP address) is stored on network card and because there is a
lot of traffic on the Ethernet, you need to install network management software, such as ADM, for the checking of how to wake up the
system. Note that, at least 600mA ATX standby current is required to support the LAN card for 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, AX45-8X Max implements 3300μF 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.

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 possible) so that clock
skew will be controlled within few a pico second (1/10
Sec)

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

a. If you assign the whole disk to your Win 98 system (FAT 16 or FAT 32), please run "aozvhdd /c /file". Please remember sufficient
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. The utility will locate the space automatically.
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.

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 992MHz
(248MHz x 4) 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
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.
