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

This motherboard supports ATA6 6, 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.

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, MX46U2-VN implements 2200μF and 3300μF capacitors, which are much larger than normal capacitors (1000 & 1500μf)

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 (1/10

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.
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

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.

AATTAA ((AATT AAttttaacchhmmeenntt))
Before talking about ATA (AT Attachment), we must understand DMA (Direct Memory Access), which allows devices to skip the CPU
devices and access memory directly. DMA specification could not only eliminate the workload of CPU, but also accelerate the transmission
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. ATA 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
bus on the computer. ATA transfer rate then had been developed to 133MHz/Sec and would come out with fastest rate later (please refer to
Serial ATA
DMA, data transfer rate is 16.6MHz/s.
Ultra DMA, data transfer rate is 16.6MHz x 2 = 33MB/s.

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).

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.
