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

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).

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).

This motherboard supports ATA6 6This 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 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, MX46-533V / MX46-533 Max 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.

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

Sec)

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 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.

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.

89

MMXX4466--553333VV // MMXX4466--553333 MMaaxx OOnnlliinnee MMaannuuaall

AATTAA//110000

ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as ATA/6 6 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.

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 to support bus master 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.

CCOODDEECC ((CCooddiinngg aanndd DDeeccooddiinngg))

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.

DDDDRR ((DDoouubbllee DDaattaa RRaatteedd)) SSDDRRAAMM

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

DIMMs are made by FPM/EDO

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.

EEVV66 BBuuss

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.

FFCCCC DDooCC ((DDeeccllaarraattiioonn ooff CCoonnffoorrmmiittyy))

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.

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.

PPaarriittyy BBiitt

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.

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.

PPCC--11660000 oorr PPCC--22110000 DDDDRR DDRRAAMM

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)

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 as PIO and DMA.
