This motherboard supports AMD® Athlon and Duron Socket 462 series CPU. Be careful of CPU orientation when you plug it into

CPU socket (with CPU Overheat Protection function implemented, the system will be automatically power off when the

temperature of CPU reached 97 degree, but works on AthlonXP CPU only).

1. Pull up the CPU socket lever and

up to 90-degree angle.

2. Locate Pin 1 in the socket and look for a black dot or cut edge on the CPU upper interface. Match Pin 1 and cut edge, then insert the CPU into the socket.

With AMD platform substantially keeps increasing the speed of its CPU, it inevitably led to the annoying problem of high CPU

operation temperature at the same time. In order to prevent accidental failure of CPU fan, which could cause the burning down

of the AthlonXP CPU, we, AOpen, have meticulously developed a new technology, named, O.H.P. (Overheat Protection)

Technology to protect them. Thanks to the intelligent monitoring design of AOpen O.H.P. technology, user can now finally set

their mind at ease even when fan failed to work without fearing the possible damage of CPU.

Under the circumstances that CPU fan is running properly, AthlonXP temperature should be way below the highest temperature

limit of 97℃. However, if CPU fan accidentally becomes

malfunction or improperly installed, the CPU temperature

would rocket abruptly, and you may find your system

hang up or crying over the smoking CPU if you haven’t

installed AOpen O.H.P. previously. With AOpen O.H.P.

technology applied, the specific thermal detection pins on

AthlonXP CPU would sense voltage difference when

processor is overheated with fan failed, and the overheat

protection system would immediately send out a signal to

abort your system by cutting CPU electricity before any

damage is done. Unlike other manufacturers who use

BIOS or software to control the power supply of CPU,

AOpen O.H.P. Technology is purely hardware-controlled

the minute after system boot-up, and occupies no system

resource. We are pleasant to phase in this practical

function on all AOpen AMD series motherboards to

protect customer’s valuable hardware and personal data.

With this motherboard, AOpen provides a very special, useful feature for overclockers. When you

power-on the system, the BIOS will check last system POST

enable “Watch Dog Timer” function immediately, and set the CPU FSB

that 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 higher system performance without removing the

cover of system housing, and be able to set the jumper to clear CMOS data when your system hanged.

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, http://english.aopen.com.tw/tech/download/skin

TThhee nnooiissee iiss ggoonnee!!!! -------- SSiilleennttTTeekk

As the clock of CPU keeps rocketing higher and higher, it inevitably brings higher heat and

system temperature in a relative way. The way we deal with this heat problem, however, is to

spare no effort to add one fan after another to protect our pampered system, expecting these

fans could cool down our machine as much as it could.

But at the same time, we believe that same amount of users are affected terribly while working with their PC by the irritating

noises of these fans. As a matter of fact, we do not have to get our fans running at such a high speed in most cases; on the

contrary, we discovered that having your fans running at appropriate time and speed could not only reduce the noise, but also

consume the least power the system

needed, so as to prevent over-wasting

of energy resource.

Today, AOpen Motherboard is honored

to bring you a new overall solution,

SilentTek, to have your system quiet. To

collocate with hardware circuit, BIOS

and the utility under Windows,

SilentTek combined “Hardware-Status

Monitoring”, “Overheat Warning” and

“Fan Speed Control” with user-friendly

interfaces to provide you a perfect

balance between noises, system

performance and stability.

MMKK7799GG OOnnlliinnee MMaannuuaall

The first image you have here is the Voltage Status page. You can find current status of all voltages and set your expected margins of warning level.

You may check your system voltage from the indicating bar here.

In “Temp/Fan/Case” page, you may get aware of the current temperature of CPU and the heat inside chassis, plus checking if fans are running properly.

Of course, you may set your defaulted lowest margin for your fans and the SilentTek would also pop up a message box and alarm you when the fan is rotating slower than this specified speed.

You may set the highest margin of your CPU and system temperature as default, and SilentTek would pop up a message box and alert you with alarm when the temperature goes beyond the specified margin.

MMKK7799GG OOnnlliinnee MMaannuuaall

The following page is sure to be the most important part of this utility, you may control the rotation speed of specific fans you got

with options inside in this page. Respectively illustrate as follow:

1. Smart FAN Control: This is the default setting of

SilentTek and can be used for any branded computer

housing. With a special algorithm developed by

AOpen, the fan speed is automatically adjusted by

the factors of CPU and ambient temperature.

Ease-of-use and trouble free at your service.

2. Fixed FAN Control: Under this setting, a desired fan

speed is set fixed when operating.

3. Multiple Level Control: This is the most versatile

setting that allows you to set fan speed in relation to

temperature. You may find this setting fits youbest.

4. AOpen Recommend Setting: This setting is

designed specifically for AOpen housing. A series of

lab tests were conducted under the real world

scenario to determine optimum fan speed to reduce

noise level within CPU working condition and

temperature. Most of the time, the fan would remain

CD-ROM Rotation Speed Control: by enabling the CD-ROM

Rotation Speed Control, you can adjust the rotation speed of

your CD-ROM. When you set the speed to high level, the

CD-ROM will work at its fastest speed and it will run at basic

required speed while you set the value to low speed.

still when CPU is not fully utilized.

Note: Due to there are hundreds different brands of fan

on the market, there might be some inaccuracy

occurred when you have had adjusted your rotation

speed; this is still under criterion and please assured

that it won’t cause any problem to y our system.

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 who we call them "Overclocker".

This section is dedicated to overclockers.

This high performance motherboard is designed for maximum 133MHz CPU bus clock. But it comes with clock generator of

200MHz when we design it to accommodate future CPU bus clock. Our lab test results shown that 200MHz is achievable when

proper setting and qualified components were presented, but not guarantee that it would work properly on your side. The CPU

clock ratio can be up to 12.5x that supports almost all of Athlon / Duron 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, SDRAM, 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

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

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, 66MHz x 4bytes

x 8 =2.1GB/s. AOpen is the first company to support 4X AGP motherboards by both AX6C (Intel 820) and MX64/AX64 (VIA

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.

MMKK7799GG 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.

AATTAA//113333

ATA/133 is a new IDE specification under developing. ATA/133 uses both rising edge and falling edge as ATA/ 66 but clock cycle

time is reduced to 30ns. The data transfer rate is (1/30ns) x 2 bytes x 2 = 133MB/s. To use ATA/133, 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.

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.

MMKK7799GG OOnnlliinnee MMaannuuaall

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 is the technology of Alpha processor from Digital Equipment Corporation. EV6 bus uses both rising and falling clock

edge to transfer data, similar as DDR RAM 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.

IIEEEEEE 11339944

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 // PPCC--22110000// PPCC--22770000 // PPCC--33220000 DDDDRR DDRRAAMM

Based on FSB frequency, the DDR DRAM has 200MHz, 266MHz and 333 MHz three types of working frequency. Because of

DDR DRAM data bus is 64-bit, it provides data transfer bandwidth up to 200x64/8=1600MB/s, 266x64/8=2100MB/s,

333x64/8=2700MB/s and 400x64/8=3200MB/s. Hence, the PC-1600 DDR DRAM is working with 100MHz, PC-2100 DDR DRAM

is working with 133MHz, PC-2700 DDR DRAM is working with 166MHz and PC-3200 DDR DRAM is working with 200MHz FSB

frequency.

The PnP specification suggests a standard register interface for both BIOS and operating system (such as Windows 95). These

registers are used by BIOS and operating system to configure system resource and prevent any conflicts. PnP BIOS or

operating system will automatically allocate the IRQ/DMA/Memory. Currently, almost all the PCI cards and most ISA cards are

already PnP compliant.

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)

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 as PIO and DMA.
