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.

into 3 sockets; however, when you install PC2700 DDR SDRAM, we suggest you to install DIMM1 and DIMM2 ONLY.
Warning: Please note that double-side DDR SDRAM
is not allowed to be installed on both DIMM2 and
DIMM3. But if you have had installed two double-side
DDR SDRAM on them, the system can only read one

DDR SDRAM utilizes the existing SDRAM infrastructure and technology while doubling the nominal bandwidth available to
systems. To put it in a simple way, DDR SDRAM is like data going along a two lane highway, while at the same time data in
traditional SDRAM go along a one way street. Therefore, it is a more advanced technology that provides a great overall
improvement in system performance. DDR266 (PC2100) runs two times faster than the traditional PC133 SDRAM with the
speed of Front Side Bus (FSB) up to 266MHz. (2x133=266). And DDR333 (PC2700) is running at 333MHz FSB. Both PC2100
and PC2700 are a new naming standard for speed of DDR 266 and DDR 333, representing their theoretical speeds of the RAM.
The theoretical transfer rate of DDR 266 (PC2100) is 2.1GB/s and 2.7GB/s is for DDR 333 (PC2700).

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

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-current protection.
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, AX4PER / AX4PER-N implements 3300μF capacitors, which is much larger than normal capacitor (1000 and
1500μF) and it provides better stability for CPU power.

Have you been fed up with the conservative and immutable POST screen? Let’s rule out the
tradition idea that POST screen are stiff and frigid, and let AOpen show you the newly
developed VividBIOS to experience the lively vivid colorful POST screen!
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

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.

AAXX44PPEERR // AAXX44PPEERR--NN 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.
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))

DDIIMMMM ((DDuuaall IInn LLiinnee MMeemmoorryy MMoodduullee))
DIMM socket has total 168-pin and supports 64-bit data. It can be single or double side, the golden finger signals on each side
of PCB are different, and that is why it was called Dual In Line. Almost all DIMMs are made by SDRAM
Note that some old DIMMs are made by FPM/EDO
DDMMAA ((DDiirreecctt MMeemmoorryy AAcccceessss))
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 in 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.

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.

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.
