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:

All conductors resist the flow of current to some extent and i n order to eliminate resistance to minimum, a most economical way
to reduce resistance is to make conductor as efficient as possible by providing s o-called “conduit” to channel the current flow.
Resistance also creates heat and it has to be reduc ed to a controllable level. What AOpen engineers are doing is to provide a
better path to reach optimum power route to efficiently deliver power (both voltage and current) to destination without creating
heat that’s normally accompanied by high current with resistance during the journey.
In a typical motherboard design, there are 4 layers of copper for the entire circuitry where both VCC and ground are sandwiched
between solder side and component side. In the older generation motherboard when bus speed and component numbers are
low, it is quite sufficient, but as the performance of today’s personal computer has reached to PC133 and operating over 1GHz
in CPU speed, the old method seems to be crippled by dilemma. Today’s motherboard design faces challenge of providing fast

AAXX33SS MMaaxx//AAXX33SS PPlluuss IIII--UU OOnnlliinnee MMaannuuaall
speed with low noise that is detrimental to the system stability. In order to provide every critical part of circuitry within the PCB,
AOpen deploys a new design concept called “Power Bridge”. These bridges are strategically place within the motherboard
design that provides both voltage and current to a targeted PCB region. This extra power is so pure that it contains no inherit
noise when travel through VCC and ground plane. Further, since the extra power is via “Power Bridge”, PCB VCC and Ground
will have lesser current flow through and lesser thermal problem.
Benefits
1. Increase current flow and eliminate accompanied heat
2. Even current distribution within motherboard
3. Better PCB layout and component placement

Besides the deployment of Power Bridge, a group of large capacitors that meet the requirements of today’s high performance
motherboard design. The theory behind this is long transmission lines have considerable inductanc e and capacitance as well as
resistance. When a current flows through the line, inductance and capacitance have the effect of varying the voltage on the line
μμμμ
ffff
LLooww EESSRR CCaappaacciittoorr
as the current varies. Thus the supply voltage varies with
the load. Several kinds of devices are used to overcome
this undesirable variation, in an operation called regulation
of the voltage. They include induction regulators and
three-phase synchronous motors (called synchronous
condensers), both of which vary the effective amount of
inductance and capacitance in the transmission circuit.
Inductance and capacitance react with a tendency to
nullify one another. When a load circuit has more inductive
than capacitive reactance, as almost invariably occurs in
large power systems, the amount of power delivered f or a
given voltage and current is less than when the two are
equal. The ratio of these two amounts of power is c alled
the power factor. Because transmission-line losses are
proportional to current, capacitance is added to the circuit
when possible, thus bringing the power factor as nearly as
possible to 1. For this reason, large capacitors are
frequently inserted as a part of power-transmission
systems.

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. B elow is a timing diagram captured by a Digital Storage Scope, it
shows the voltage transient is only 143mv even when maximum 18A current is applied.

By flashing your motherboard, you agree to accept the possibility of BIOS flash failure. If you motherboard is work ing and is
stable, and there are no major bugs that were fixed by a latter BIOS revision, we recommend that you DO NOT try to upgrade
your BIOS.
By doing so, you are taking a risk of BIOS flash failure. If you indeed intent on upgrading, PLEASE BE SURE to use the right
BIOS revision for the right motherboard model.
AOpen Easy Flash is a li ttle different than traditional flash method. The BIOS
and you simply run a single commend to complete the flash process.
binary file and flash routine are linked together
Caution: AOpen Easy Flash BIOS programs are designed to be
compatible with the Award BIOS. At the date of this note, AOpen
Easy Flash BIOS programs are not available for AMI BIOS. AMI
BIOS appears mostly only on old 486 boards and some early
Pentium boards. Please be sure to vi ew the README compressed
inside the BIOS package before upgrading, and follow upgrade
instructions carefully. This will minimize the chance of flash
failures.

Below are the steps for easy flashing procedures: (applies for Award BIOS ONLY)
1. Download new BIOS upgrade zip
For example, A X3SP2U102.ZIP.
2. Run shareware PKUNZIP (http://www.pkware.com/
binary BI OS f il e an d th e flas h uti li ty.
Or Winzip (http://www.winzip.com/
3. Save the unzipped file into a bootable floppy disk.
For example, A X3SP2U102.BIN & AX3SP2U102.EXE
4. Reboot the system to DOS mode without loading any memory handler (such as E MM386) or device driver. It needs
around 520K free memory spaces.
5. Execute A:> A X3SP2U102 and the program will do the rest of it.
DO NOT turn off the power during FLASH PROCESS until you are asked to!!
6. Reboot system and press <Del> to enter BIOS setup
Warning: The new BIOS upgrade will permanently replace your
original BIOS's settings and PnP information when flashing. You
may need to reconfigure your BIOS setting and re-install
Win95/Win98 as well as your add-on cards, so that your system
can go back to work as normal.

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 100MHz 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 achievabl e 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 t o adjust CPU core voltage. The CPU clock ratio can be
up to 8x that supports almost all of Pentium III/Celeron CPUs in the future and provides flexibility for overclockers. For your
reference, the following configurations are what we f eel 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, 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 m ore 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 4byt e 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
