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: english.aopen.com.tw

The power circuit of the CPU core voltage must be checked to ensure system stability for high speed CPUs (such as the new

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.

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

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

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

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

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 333 MHz three types of working frequency. Because of DDR

DRAM data bus is 64-bit, it provides data transfer bandwidth up to 200x64/8=1600MB/s, 266x64/8=2100MB/s, 333x64/8=2700MB/s

and 400x64/8=3200MB/s. Hence, the PC-1600 DDR DRAM is working with 100MHz, PC-2100 DDR DRAM is working with 133MHz,

PC-2700 DDR DRAM is working with 166MHz and PC-3200 DDR DRAM is working with 200MHz FSB frequency.

Mac … with different PDF reader. You can also read PDF file by web browser such as IE and Netscape, note that you need to

install PDF plug-in first (Included in Acrobat Reader).

PPnnPP ((PPlluugg aanndd PPllaayy))

The PnP specification suggests a standard register interface for both BIOS and operating system (such as Windows 95). These

registers are used by BIOS and operating system to configure system resource and prevent any conflicts. PnP BIOS or operating

system will automatically allocate the IRQ/DMA/Memory. Currently, almost all the PCI cards and most ISA cards are already PnP

compliant.

PPOOSSTT ((PPoowweerr--OOnn SSeellff TTeesstt))

The BIOS self-test procedure after power-on, sometimes, it is the first or the second screen shown on your monitor during system

boot.

RRDDRRAAMM ((RRaammbbuuss DDRRAAMM))

Rambus is a memory technology that uses large burst mode data transfer. Theoretically, the data transfer should be high than

. RDRAM is cascaded in channel operation. For Intel 820, only one RDRAM channel is supported, 16-bit data per channel,

SDRAM

and this channel may have maximum 32 RDRAM devices, no matter how many

RRIIMMMM ((RRaammbbuuss IInnlliinnee MMeemmoorryy MMoodduullee))

184-pin memory module that supports RDRAM memory technology. A RIMM memory module may contain up to maximum of 16

RDRAM devices.

SSDDRRAAMM ((SSyynncchhrroonnoouuss DDRRAAMM))

SDRAM is one of the DRAM technologies that allow DRAM to use the same clock as the CPU host bus (EDO and FPM are

asynchronous and do not have clock signal). It is similar as

DIMM

and operates at 3.3V. AOpen is the first company to support dual-SDRAM DIMMs onboard (AP5V), from Q1 1996

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

motherboard design.

EDO

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

DRAM and supports 32-bit data. SIMM had been phased out on current

to decide best timing for this DIMM or RIMM.
