About “User Upgrade Optional” and “Manufacture Upgrade Optional”…
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

AOpen “Watch Dog Timer”
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 status. If it succeeded, the BIOS will enable “Watch Dog
Timer” function immediately, and set the CPU FSB frequency 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 system to get
a higher system performance without removing the system housing and save the hassle from setting the jumper to clear CMOS data when
system hangs.

DDR 266(PC2100) Supported
DDR SDRAM utilizes the existing SDRAM infrastructure and technology while doubling the nominal bandwidth available to systems. To put
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).
PC2100 is a new naming standard for speed of DDR 266, representing their theoretical speeds of the RAM. The theoretical transfer rate of
DDR 266 (PC2100) is 2.1GB/s.

ATA/133 Supported
This motherboard supports ATA66, 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. Compared to traditional ATA/100, ATA/133 has up to 33
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

Low ESR Capacitor
The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for the stability of

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.

Layout (Frequency Isolation Wall)
For high frequency operation, especially when

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 (1/1012

Vivid BIOS technology
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 change your

Overclocking
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 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
Pentium® 4 CPUs in the future and provides flexibility for overclockers.
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.
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.

Glossary
AC97
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.
ACPI (Advanced Configuration & Power Interface)
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. The chipset or super I/O chip needs to provide standard register interface to operating system (such as
Windows 98). This is a bit similar as the PnP register interface. ACPI defines ATX momentary soft power switch to control the power state
transition.
AGP (Accelerated Graphic Port)
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.

APM (Advanced Power Management)
Unlike ACPI, BIOS controls most APM power management functions. AOpen Suspend to Hard Drive is a good example of APM power
management.
ATA (AT Attachment)
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.
ATA/66
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.
91
MX46 U2
Online Manual
ATA/100
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.
ATA/133
Compared to traditional ATA/100, ATA/133 has been up to 33 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.
BIOS (Basic Input/Output System)
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.
Bus Master IDE (DMA mode)
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.

CNR (Communication and Networking Riser)
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.
CODEC (Coding and Decoding)
Normally, CODEC means a circuit that can do digital to analog conversion and also the analog to digital conversion. It is part of AC97
sound/modem solution.
DDR (Double Data Rated) SDRAM
DDR SDRAM utilizes the existing DRAM infrastructure and technology while doubling the nominal bandwidth available to systems in an
easy to design and simple to adopt way. Initially a perfect solution for memory intensive server and workstation applications, DDR low cost
and low voltage will ultimately make it an ideal solution for all segments of the PC market, high performance desktop and mobile PCs,
Value PCs and even Internet Appliances and mobile devices.
DIMM (Dual In Line Memory Module)
DIMM socket has total 168-pin and supports 64-bit data. It can be single or double side, the golden finger signals on each side of PCB are
different, and that is why it was called Dual In Line. Almost all DIMMs are made by SDRAM, which operate at 3.3V. Note that some old
DIMMs are made by FPM/EDO and only operate at 5V. Do not confuse them with SDRAM DIMM.

DMA (Direct Memory Access)
Channel for communications between the memory and surrounding devices.
ECC (Error Checking and Correction)
The ECC mode needs 8 ECC bits for 64-bit data. Each time memory is accessed; ECC bits are updated and checked by a special
algorithm. The ECC algorithm has the ability to detect double-bit error and automatically correct single-bit error while parity mode can only
detect single-bit error.
EDO (Extended Data Output) Memory
The EDO DRAM technology is actually very similar to FPM (Fast Page Mode). Unlike traditional FPM that tri-states the memory output data
to start the pre-charge activity, EDO DRAM holds the memory data valid until the next memory access cycle, that is similar to pipeline effect
and reduces one clock state.
EEPROM (Electronic Erasable Programmable ROM)
Also known as E2PROM. Both EEPROM and Flash ROM can be re-programmed by electronic signals, but the interface technology is
different. Size of EEPROM is much smaller than flash ROM.
EPROM (Erasable Programmable ROM)
Traditional motherboard stores BIOS code in EPROM. EPROM can only be erased by ultra-violet (UV) light. If BIOS has to be upgraded,
you need to remove EPROM from motherboard, clear by UV light, re-program, and then insert back.

EV6 Bus
EV6 Bus in the technology of Alpha processor from Digital Equipment Corporation. EV6 bus uses both rising and falling clock edge to
transfer data, similar as DDR SDRAM or ATA/66 IDE bus.
EV6 Bus Speed = CPU external bus clock x 2.
For example, 200 MHz EV6 bus is actually using 100 MHz external bus clock, but the equivalent speed is 200 MHz.
FCC DoC (Declaration of Conformity)
The DoC is component certification standard of FCC EMI regulations. This standard allows DIY component (such as motherboard) to apply
DoC label separately without a shielding of housing.
FC-PGA (Flip Chip-Pin Grid Array)
FC means Flip Chip, FC-PGA is a new package of Intel for Pentium III CPU. It can plug into SKT370 socket, but require motherboard to
add some signals on socket 370. That is, the motherboard needs to be redesigned. Intel is going to ship FC-PGA 370 CPU and phase out
slot1 CPU.
Flash ROM
Flash ROM can be re-programmed by electronic signals. It is easier for BIOS to upgrade by a flash utility, but it is also easier to be infected
by virus. Because of increase of new functions, BIOS size is increased from 64KB to 256KB (2M bit). AOpen AX5T is the first board to
implement 256KB (2Mbit) Flash ROM. Now flash ROM size is moving to 4M bit on AX6C (Intel 820) and MX3W (Intel 810) motherboard. ,
AOpen motherboard uses EEPROM for jumper-less and battery-less design.

IEEE 1394
IEEE 1394 is a low-cost digital interface originated by Apple Computer as a desktop LAN and developed by the IEEE 1394 working group.
The IEEE 1394 can transport data at 100, 200 or 400 Mbps. One of the solutions to connect digital television devices together at 200 Mbps.
Serial Bus Management provides overall configuration control of the serial bus in the form of optimizing arbitration timing, guarantee of
adequate electrical power for all devices on the bus, assignment of isochronous channel ID, and notification of errors. There are two type of
IEEE 1394 data transfer: asynchronous and isochronous. Asynchronous transport is the traditional computer memory-mapped, load and
store interface. Data requests are sent to a specific address and an acknowledgment is returned. In addition to an architecture that scales
with silicon technology, IEEE 1394 features a unique isochronous data channel interface. Isochronous data channels provide guaranteed
data transport at a pre-determined rate. This is especially important for time-critical multimedia data where just-in-time delivery eliminates
the need for costly buffering.

Parity Bit
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.
PBSRAM (Pipelined Burst SRAM)
For Socket 7 CPU, one burst data read requires four QWord (Quad-word, 4x16 = 64 bits). PBSRAM only needs one address decoding time
and automatically sends the remaining QWords to CPU according to a predefined sequence. Normally, it is 3-1-1-1, total 6 clocks, which is
faster than asynchronous SRAM. PBSRAM is often used on L2 (level 2) cache of Socket 7 CPU. Slot 1 and Socket 370 CPU do not need
PBSRAM.

Based on FSB frequency, the DDR DRAM has 200MHz, 266MHz and 333MHz three types of working frequency. Because DDR DRAM
data bus is 64-bit, it provides data transfer bandwidth up to 200x64/8=1600MB/s, 266x64/8=2100MB/s and 333x64/8=2700MB/s in these
current three DDR DRAM. Therefore, the PC-1600 DDR DRAM is working with 100MHz, PC-2100 DDR DRAM is working with 133MHz
and PC-2700 with 166MHz FSB frequency.

registers between the memory core and I/O pins. Using VCM technology results in reduced data access latency and reduced power
consumption.
