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.

Warning: The specification of the IDE cable is a

maximum of 46cm (18 inches); make sure your

cable does not exceed this length.

Tip: For better signal quality, it is recommended

to set the far end side device to master mode

and follow the suggested sequence to install

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 600mA ATX standby current is required to support the LAN card for this function.

The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for

stability of CPU power. The location of where to put these capacitors is another know-how that requires experience and detail

calculation.

MXX3366LLEE--UU // MMXX3366LLEE--UUNN

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 18A current is applied.

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 133MHz CPU bus clock. But it comes with clock generator of

150MHz when we design it to accommodate future CPU bus clock. Our lab test results shown that 150MHz is achievable when

proper setting and qualified components were presented, we feel quite comfortable overclocking to 150MHz. 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 16x 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 feel comfortable at 150MHz bus clock.

But not guarantee. ☺

MXX3366LLEE--UU // MMXX3366LLEE--UUNN

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.

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.

AACC9977

Basically, AC97 specification separates sound/modem circuit to two parts, digital processor and a CODEC for analogy I/O they

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.

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.

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.

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
