When you read this online manual and start to assemble your computer system, you may find some functions are “Optional”,

and some “Upgrade Optional”. Although all AOpen motherboards include many amazing and powerful features, in some

situations, those powerful features are not commonly used by every user. Therefore, we changed some key features to

“Optional” for you to choose. With optional functions that can be upgraded by users, we define 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 are welcomed to visit AOpen official web

site: www.aopen.com

for more detail information.

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.

Warning: The specification of the IDE cable is a maximum of 46cm (18 inches);

make sure your cable does not exceed this length.

Tip:

1. For better signal quality, it is recommended to set the far end side device to

master mode and follow the suggested sequence to install your new

device. Please refer to above diagram

2. To achieve the best performance of Ultra DMA 66/100/133 hard disks, a

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. 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.

This feature is very similar as Wake On Modem, 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.

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

erfectly.

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.

Moreover, AX4B Pro-533 implements 3300μF capacitors that have much larger capacity than normal capacitor (1000 and 1500

μf) and provide better stability for CPU power.

Except these powerful functions above, Open JukeBox Player is also equipped with another fancy feature for you to

change its “skin”. You can download as many skins as you want from AOpen Website, and changing them whenever

you want by using this useful utility – EzSkin – which may also be downloaded from our website.

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 Vivid BIOS screen or to download your favorite Open JukeBox skin. If you see this little logo your model name on the BIOS download page,

your motherboard supports this innovative feature!

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

to operating system (such as Windows 98). This is a bit similar as the PnP

power 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 chip needs to provide standard register interface

A disc bundled with AOpen motherboard product; there are motherboard drivers, Acrobat Reader for PDF online manual and

other useful utilities.

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.

Page 96

XX44BB PPrroo--553333 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.

AATTAA//113333

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.

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.

XX44BB PPrroo--553333 OOnnlliinnee MMaannuuaall

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

Note that some old DIMMs are made by FPM/EDO

DDMMAA ((DDiirreecctt MMeemmoorryy AAcccceessss))

Channel for communications between the memory and surrounding devices.

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.
