When you read this online manual and start to assemble your computer system, you may find some of functions are called
“Manufacturer Upgrade Optional”, and some are called “User 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 “Manufacturer Upgrade Optional” for you to choose. Some optional functions that can be upgraded by
users, we call them “User Upgrade Optional”. As for those optional functions that can’t be upgraded by ourselves, we call them
“Manufacturer Upgrade Optional”. If needed, you can contact our local distributors or resellers for purchasing “User Upgrade
Optional” components, and again you can visit AOpen official web site: http://english.aopen.com.tw/
for more detail information.

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 only 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.

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 60 current is applied.

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.

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.

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

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
248MHz when we design it to accommodate future CPU bus clock. Our lab test results shown that 166MHz is achievable when
proper setting and qualified components were presented, we feel quite comfortable overclocking to 166MHz. Not only that, this
motherboard has full-range (CPU core voltage) settings and an option to adjust CPU core voltage. The CPU clock ratio can be
up to 12.5x that supports almost all of Athlon / Duron / AthlonXP CPUs in the future and provides flexibility for overclockers. For
your reference, the following configurations are what we feel comfortable at 166MHz bus clock.
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 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

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.
96
AAKK7777--333333FF // AAKK7777--333333FFNN 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
ATA/133 is a new IDE specification under developing. ATA/133 uses both rising edge and falling edge as ATA/ 6 6 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.

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 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 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 package of Intel for Pentium III CPU. It can plug into SKT370 socket.
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.
