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: www.aopen.com
for more detail information.

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, and without removing
the cover of system housing to set the jumper to clear CMOS data when your system hanged.

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 ATA33, ATA 66 or ATA100 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.

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 chipset that supports 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 600m A ATX standby current is required to support the LAN c ard for t his func tion.

Over Current Protection has been popularly implemented on ATX 3.3V/5V/12V switching power supply for a while. However,
new generation CPU is able to use regulator of different voltages to transfer 12V to CPU voltage (for example, to 2.0V). This
motherboard is with switching regulator onboard that supports CPU over-current protection, and it applies to 3.3V/5V/12V power
supply for providing full line over-c urrent prot ect ion.
Note: Although we have implemented protection circuit try to prevent any human operating
mistake, there is still certain risk that CPU, memory, HDD, add-on cards installed on this
motherboard may be damaged because of component failure, human operating error or unknown
nature reason. AOpen cannot guaranty the protection circuit will always work perfectly.

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.
Not only that, AX4GR / AX4GR-N implements 3300μF capacitors, which is much larger than normal capacitor (1000 and 1500μ
f) and it provides better stability for CPU power.

For high frequency operation, especially overclocking,
layout is the most important factor to make sure
chipset and CPU working in stable condition. The
layout of this motherboard implements AOpen’s
unique design called “ Frequency Isolation Wall”.
Separating each critical portion of motherboard into
regions where each region operates in a same or
similar frequency range to avoid cross talk and
frequency interference between each region’s
operations and condition. The trace length and route
must be calculated carefully. For example, the clock
trace must be equal length (not necessarily as short
as possible) so that clock skew will be controlled
within few a pico second (1/10

memory and screen image) into hard disk, and then the system can be totally power off. Next time, when power is on, you can
resume your original work directly from hard disk within few seconds without go through the Windows booting process and run
your application again. If your memory is 64MB, normally, you need to reserve at least 64MB HDD space to save your memory

Windows 95/98, 98SE/ME, NT4.0/2000, or even the latest Windows XP.
In the meanwhile, in order to provide a much more user-friendly operating environment, AOpen EZWinFlash is natively designed
to have multi-language function to provide easier way for users’ usage in changing BIOS setting.
Note: The model name on this BIOS picture is for reference only. It may not be the exact model name.
Caution: By updating your motherboard, you are
taking a risk of BIOS flash failure. If your
motherboard is working stable, and there are no
major bugs that had been fixed by a latter BIOS
revision, we recommend that you DO NOT try to
upgrade your BIOS.
If you intent on upgrading, PLEASE BE SURE to
get the right BIOS revision for the right motherboard
model to avoid any possibility failure.

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. But it comes with clock generator of
248MHz when we design it to accommodate with future CPU bus clock. Our lab test results showed that 120MHz 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

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. AOpen is the
first company to support 4X AGP motherboards by both AX6C (Intel 820) and MX64/AX64 (VIA 694x), started from Oct 1999.

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.

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.
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))

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.
