When you read this online manual and start to assemble your computer system, you may find some of functions are called
“Optional”, and some are called “Upgrade Optional”. Though all AOpen motherboards include many amazing and powerful features,
in some situations, these powerful features are not used to every user. Hence, we changed some key features as “Optional” for you
to choose. Some optional functions that can be upgraded by users, we call them “Upgrade Optional”. As for those optional
functions that can’t be upgraded by ourselves, we call them “Optional”. If needed, you can contact our local distributors or resellers
for purchasing “Upgrade Optional” components, and again you can visit AOpen official web site: www.aopen.com.tw

IDE1 is also known as the primary channel and IDE2 as the secondary channel. Each channel supports two IDE devices that make
a total of four devices. In order to work together, the two devices on each channel must be set differently to Master and Slave
mode. Either one can be the hard disk or the CDROM. The setting as master or slave mode depends on the jumper on your IDE
device, so please refer to your hard disk and CDROM manual accordingly.
This motherboard supports ATA33
modes. The IDE bus is 16-bit, which means every transfer is two bytes.

This feature is very similar as WWaakkee OOnn MMooddeemm, but it goes through local area network. To use Wake On LAN function, you must
have a network card with a chipset supporting 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.

current protection useless. This motherboard is with switching regulator onboard supports 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 try to prevent any human operating

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

For high frequency operation, especially overclocking,
layout is the most important factor to make sure
chipset and CPU 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 to 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 length (not necessarily as short
as possible) so that clock skew will be controlled
within few a pico second (1/10

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 400MHz 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

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
operating system (such as Windows 98). This is a bit similar as the PnP
switch to control the power state 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 c hip needs to provide standard register interface to

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.

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, t he s am e 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 t o support bus m aster 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.

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.
DDIIMMMM ((DDuuaall IInn LLiinnee MMeemmoorryy MMoodduullee))
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

EECCCC ((EErrrroorr CChheecckkiinngg aanndd CCoorrrreeccttiioonn))
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.
EEDDOO ((EExxtteennddeedd DDaattaa OOuuttppuutt)) MMeemmoorryy
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.
EEEEPPRROOMM ((EElleeccttrroonniicc EErraassaabbllee PPrrooggrraammmmaabbllee RROOMM))
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.
EEPPRROOMM ((EErraassaabbllee PPrrooggrraammmmaabbllee RROOMM))
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.

FFCC--PPGGAA ((FFlliipp CChhiipp--PPiinn GGrriidd AArrrraayy))
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.
FFllaasshh RROOMM
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 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.

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 tim e, if m emo ry i s r ea d wit h o dd n umb er of "1 ", t he pa rit y

PPBBSSRRAAMM ((PPiippeelliinneedd BBuurrsstt SSRRAAMM))
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 and 266MHz two type of working frequency. Because of DDR DRAM data
bus is 64-bit, it provides data transfer bandwidth up to 200x64/8=1600MB/s, and 266x64/8=2100MB/s. Hence, the PC-1600 DDR
DRAM is working with 100MHz and PC-2100 DDR DRAM is working with 133MHz FSB frequency.

Ultra DMA (or, more accurately, Ultra DMA/33) is a protocol for transferring data between a hard disk drive through the computer’s
data path (or bus) to the computer’s random access memory (RAM). The Ultra DMA/33 protocol transfers data in burst mode at a
rate of 33.3MB/s, twice as fast as the previous Direct Access Memory (DMA) interface. Ultra DMA was developed as a proposed
industry standard by the Quantum corporation, makes of hard disk drives, and Intel, makes of chipset that support computer bus
technology. Ultra DMA support in your computer means that it will boot (start) and open new applications more quickly. It will help
users of graphic-intensive and applications that require large amounts of access to data on the hard disk drive. Ultra DMA uses
Cyclical Redundancy Checking (CRC), offering a new level of data protection. Ultra DMA uses the same 40-pin IDE interface cable
