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

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.

This motherboard supports ATA3 3

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 400MHz CPU bus clock. Some lab tests results showed that 133MHz is

achievable when proper setting and qualified components were presented. 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.

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

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. Our company is the first company to support 4X AGP

motherboards by both AX6C (Intel 820) and MX64/AX64 (VIA 694x), started from Oct 1999.

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.

MMXX4466 OOnnlliinnee MMaannuuaall

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, 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

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.

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). 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. , our

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

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
