This chapter describes jumpers, connectors and hardware devices of this motherboard.

Note: Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and

other components. Always observe the following precautions before you install a system component.

1. Do not remove a component from its protective packaging until you are ready to install it.

2. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a

component. If a wrist strap is not available, maintain contact with the system unit throughout any

procedure requiring ESD protection.

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 www.aopen.com

for detail information.

You can clear CMOS to restore system default setting. To clear the CMOS, follow the procedure below.

1. Turn off the system and unplug the AC power.

2. Remove ATX power cable from connector PWR2.

3. Locate JP14 and short pins 2-3 for a few seconds.

4. Return JP14 to its normal setting by shorting pin1 & pin2.

5. Connect ATX power cable back to connector PWR2.

This motherboard supports Intel® Pentium 4 Socket 478 series CPU (Brookdale). Be careful of CPU orientation when you plug it

into CPU socket.

1. Pull up the CPU socket lever and

up to 90-degree angle.

2. Locate Pin 1 in the socket and look for a cut edge on the CPU upper interface. Match Pin 1 and cut edge, then insert the CPU into the socket.

Note: These pictures are for example only; it may not look exactly the same with the motherboard you purchased.

Note: P4 CPU tends to produce higher

temperature; for better heat dissipation,

we recommend you to install this

motherboard with a bigger housing.

Besides, by doing so you can preven

components from colliding.

Note: If you do not match the CPU

socket Pin 1 and CPU cut edge well, it

may damage the CPU.

Note: This socket supports

is the latest CPU package developed

by Intel. Other forms of CPU package

This motherboard comes with a retention module attached on the CPU socket when shipped, we strongly recommend you to

install AOpen special designed CPU Fan as shown below on the retention module for better heat dissipation. Please install the

CPU Fan correctly as the following pictures shown.

1. Gently put the CPU Fan down on the

retention module with clips aligning correctly to the four corners.

2. Pressing down the four clips with force one by one on the retention module.

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.

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.

MMXX44LLSS 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

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.

BIOS is a set of assembly routine/program that reside in EPROM or Flash ROM. BIOS controls Input/output devices and other

The traditional PIO (Programmable I/O) IDE requires the CPU to involve in all the activities of the IDE access including waiting

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

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.
