When you read this online manual and start to assemble your computer system, you may notice that some of the functions are marked as
“User Upgrade Optional” or “Manufacture Upgrade Optional”. Although all of AOpen’s motherboards have included many amazing and
powerful features, sometimes not every user is familiar with these powerful features. As a result of this we define features that can be
upgraded by users as “User Upgrade Optional”. You can upgrade these functions by purchasing additional devices. As for functions that
cannot be upgraded by users, we define them as “Manufacture Upgrade Optional”. If need be, you can contact our local distributors or
resellers to purchase “Manufacture Upgrade Optional” components, and again you are also welcome to visit our official website at

DDR SDRAM utilizes the existing SDRAM infrastructure and technology while doubling the nominal bandwidth available to systems. To p u t
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).
PC2100 is a new naming standard for speed of DDR 266, representing their theoretical speeds of the RAM. The theoretical transfer rate
of DDR 266 (PC2100) is 2.1GB/s.

The Over Current Protection is a popular implementation on ATX 3.3V/5V/12V switching power supply. However, the new generation CPU

Note: Although we have implemented protection circuit and tried to prevent any human operating

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 60A current is applied.

Separating each critical portion of motherboard into
regions, where each region operates in a same or similar
frequency range, we can 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 to
length (not necessarily as short as possible) so that clock
skew will be controlled within few a pico second (1/10

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
Windows 98). This is a bit similar as the PnP
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 to operating system (such as
register interface. ACPI defines ATX momentary soft power switch to control the power state

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.
86
Page 87
MMXX44GGVV 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
Compared to traditional ATA/100, ATA/133 has been up to 33 percent increase in interface speed with transfer rate of 133MB/s. ATA/13 3
performance is ideal for new operating systems, such as Window XP, that demand more storage space and faster data transfer rates from
more responsive computing experiences.
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.

industry specification and is supported by OEMs, IHV card manufacturers, silicon supplier and Microsoft.
CCOODDEECC ((CCooddiinngg aanndd DDeeccooddiinngg))
Normally, CODEC means a circuit that can do digital to analog conversion and also the analog to digital conversion. It is part of AC97
sound/modem solution.
DDDDRR ((DDoouubbllee DDaattaa RRaatteedd)) SSDDRRAAMM
DDR SDRAM utilizes the existing DRAM infrastructure and technology while doubling the nominal bandwidth available to systems in an
easy to design and simple to adopt way. Initially a perfect solution for memory intensive server and workstation applications, DDR low cost
and low voltage will ultimately make it an ideal solution for all segments of the PC market, high performance desktop and mobile PCs,
Value PCs and even Internet Appliances and mobile 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.

slot1 CPU.
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.

Based on FSB frequency, the DDR DRAM has 200MHz, 266MHz and 333MHz three types of working frequency. Because DDR DRAM
data bus is 64-bit, it provides data transfer bandwidth up to 200x64/8=1600MB/s, 266x64/8=2100MB/s and 333x64/8=2700MB/s in these
current three DDR DRAM. Therefore, the PC-1600 DDR DRAM is working with 100MHz, PC-2100 DDR DRAM is working with 133MHz
and PC-2700 with 166MHz FSB frequency.

SSIIMMMM ((SSiinnggllee IInn LLiinnee MMeemmoorryy MMoodduullee))
SIMM socket is only 72-pin, and is only single side. The golden finger signals on each side of PCB are identical. That is why it was called
Single In Line. SIMM is made by FPM or EDO
DRAM and supports 32-bit data. SIMM had been phased out on current motherboard design.
SSMMBBuuss ((SSyysstteemm MMaannaaggeemmeenntt BBuuss))
SMBus is also called I2C bus. It is a two-wire bus developed for component communication (especially for semiconductor IC). For example,
set clock of clock generator for jumper-less motherboard. The data transfer rate of SMBus is only 100Kbit/s, it allows one host to
communicate with CPU and many masters and slaves to send/receive message.
SSPPDD ((SSeerriiaall PPrreesseennccee DDeetteecctt))
SPD is a small ROM or EEPROM device resided on the DIMM or RIMM. SPD stores memory module information such as DRAM timing
and chip parameters. SPD can be used by BIOS
to decide best timing for this DIMM or RIMM.

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) interface. Ultra DMA was 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.
16.6MB/s x2 = 33MB/s
16.6MB/s x4 = 66MB/s
16.6MB/s x6 = 100MB/s
UUSSBB ((UUnniivveerrssaall SSeerriiaall BBuuss))
USB is a 4-pin serial peripheral bus that is capable of cascading low/medium speed peripherals (less than 10Mbit/s) such as keyboard,
mouse, joystick, scanner, printer and modem. With USB, the traditional complex cables from back panel of your PC can be eliminated.
UUSSBB22..00 ((UUnniivveerrssaall SSeerriiaall BBuuss))
Compared to traditional USB 1.0/1.1 with the speed of 12Mbps, USB 2.0 has a fancy speed up to 480 Mbps that is 40 times faster than the
traditional one. Except for the speed increase, USB 2.0 supports old USB 1.0/1.1 software and peripherals, offering impressive and even
better compatibility to customers.

VVCCMM ((VViirrttuuaall CChhaannnneell MMeemmoorryy))
NEC’s Virtual Channel Memory (VCM) is a new DRAM core architecture that dramatically improves the memory system’s ability to service
multimedia requirements. VCM increases memory bus efficiency and performance of any DRAM technology by providing a set of fast static
registers between the memory core and I/O pins. Using VCM technology results in reduced data access latency and reduced power
consumption.
