When you read this online manual and start to assemble your computer system, you may find some of functions are called

“Optional”, and some are called “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

“Optional” for you to choose. Some optional functions that can be upgraded by users, we call them “Upgrade Optional”. As for

those optional functions that can’t be upgraded by ourselves, we call them “Optional”. If needed, you can contact our local

distributors or resellers for purchasing “Upgrade Optional” components, and again you can visit AOpen official web site:

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

ACPI Suspend to Hard Drive is basically controlled by Windows operation system. It saves your current work (system status,

memory and screen image) into hard disk, and then the system can be totally power off. Next time, when power is on, you can

resume your original work directly from hard disk within few seconds without go through the Windows booting process and run

your application again. If your memory is 64MB, normally, you need to reserve at least 64MB HDD space to save your memory

AACC9977 CCOODDEECC

Basically, AC97 CODEC is the standard structure of PCI sound card. As we know, computer is digital-based, but music is based

on analog-based. Therefore, there must be a process to turn digital into analog during the last stage processing of sound in

computer. Hence, the component on sound card that play this important task is what we called CODEC.

Audio CODEC 97 (briefly called AC97) is the specification regulated by Intel, and it’s about the structure of audio conversion.

The special place about CODEC is that it is separated from sound card (CODEC is an independent chipset). Therefore, PCI

sound card could possess with 90db and do other application process as well. We called CODEC that meets this structure AC97

CODEC.

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

to operating system (such as Windows 98). This is a bit similar as the

power switch to control the power state transition.

AAGGPP ((AAcccceelleerraatteedd GGrraapphhiicc PPoorrtt))

The main function of AGP simply put is to tell monitor what screen information had to be shown, a visual transmission device

actually. With the rapid developing of AGP card, we can see that it had been developed from single colorful AGP card to 2D and

3D graphic. AGP supports only memory read/write operation and single-master single-slave one-to-one only. Though AGP and

PCI share the same algorithm of 32-bit, its frequencies are 66MHz and 33MHz respectively. AGP interface had been

developed from 2X to 8x.

1X AGP, data transfer rate is 66MHz x 4byte x 1 = 264MB/s

2X AGP, data transfer rate is 66MHz x 4byte x 2 = 528MB/s

4X AGP, data transfer rate is 66MHz x 4byte x 4 = 1056MB/s.

8X AGP, data transfer rate is 66MHz x 4byte x 8 = 2112MB/s.

AAMMRR ((AAuuddiioo//MMooddeemm RRiisseerr))

The CODEC circuit of AC97 sound/modem solution can be put on motherboard or put on a riser card (AMR card) that connects

AATTAA ((AATT AAttttaacchhmmeenntt))

Before talking about ATA (AT Attachment), we must understand DMA (Direct Memory Access), which allows devices to skip the

CPU devices and access memory directly. DMA specification could not only eliminate the workload of CPU, but also accelerate

the transmission of data. DMA begins with a data transfer rate of 16.6MB/Sec, but afterward developed to new data rate of

33.3MB/Sec, which is twice the data rate and we called it Ultra DMA. ATA details power and data signals between the drive

and integrated drive controller and the computer's motherboard. Two drives (master and slave) are supported. The ATA

specification allows the drive to connect directly to the ISA bus on the computer. ATA transfer rate then had been developed to

133MHz/Sec and would come out with fastest rate later (please refer to

Serial ATA

Page 86

MMXX44LLRR--GGNN // MMXX44GGVVRR--GGNN OOnnlliinnee MMaannuua

DMA, data transfer rate is 16.6MHz/s.

Ultra DMA, data transfer rate is 16.6MHz x 2 = 33MB/s.

ATA/66 , data transfer rate is 16.6MHz x 4 = 66MB/s.

ATA/100, data transfer rate is 16.6MHz x 6 = 100MB/s.

ATA/133, data transfer rate is 16.6MHz x 8 = 133MB/s.

(ATA/133 uses both rising edge and falling edge as ATA/66 but clock cycle time is reduced to 30ns.)

IEEE 1394, which also called Firewire, is a serial data transfer protocol and interconnection system. The main feature of the

Firewire that assures its adoption for the digital video and audio (A/V) consumer application is its low cost. Fire wire interface is

capable of supporting various high-end digital A/V applications, such as consumer A/V device control and signal routing, Digital

Video (DV) editing, home networking, and more than 32 channels of digital mixing. Gone are those days of expensive video

capture cards. Firewire allows for video capture from both newer DV camcorders with Firewire ports and older analog

equipment using A/V to Firewire converters.

The advantages of the IEEE1394:

High data transfer rate – Start from 400 Mbps, (with 800/1600/3200 Mbps coming soon), which is about 30 times faster than

USB 1.1.

Supports up to 63 devices (16 - daisy chained) with cable length up to about 4.5 m (14 feet).

Hot-pluggable (like USB). No need to turn of your device to connect or disconnect, and you don't need to reboot your PC. Also,

it is a plug-and-play bus.

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.

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.

PPSSBB ((PPrroocceessssoorr SSyysstteemm BBuuss)) CClloocckk

PSB Clock means the external bus clock of CPU.

CPU internal clock = CPU PSB Clock x CPU Clock Ratio

RRDDRRAAMM ((RRaammbbuuss DDyynnaammiicc RRaannddoomm AAcccceessss MMeemmoorryy))

A DRAM technology developed by Rambus Corporation*, to achieve high speed of memory through the use of multiple channels

in parallel by 16-bits. Basically, RDRAM uses new structure of Multibank, which is quite different from FPM, EDO, SDRAM.

Using different memory module as well, RDRAM uses “RIMM” with transfer rate of 600/700/800MHz, providing bandwidth as

high to 1.6GB.

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 PBSRAM to use burst mode transfer. SDRAM comes in 64-bit

168-pin DIMM and operates at 3.3V, and have been gradually replaced by DDR RAM.

SSAATTAA ((SSeerriiaall AATTAA))

The Serial ATA specification is designed to overcome speed limitations while enabling the storage interface to scale with the

growing media rate demands of PC platforms. Serial ATA is to replace parallel

systems and drivers, adding performance headroom for years to come. It is developed with data transfer rate of 150

Mbytes/second, and 300M/bs, 600M/bs to come. It reduces voltage and pins count requirements and can be implemented with

thin and easy to route cables.

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

with the compatibility with existing operating

ATA

to decide best timing for this DIMM or RIMM.

UUSSBB 22..00 ((UUnniivveerrssaall SSeerriiaall BBuuss))

A Universal Serial Bus (USB) is an external bus (an interconnect) standard that supports data transfer rates of 12 Mbps. A single

USB port can be used to connect up to 127 peripheral devices, such as mouse, modems and keyboards. Introduced in 1996,

USB has completed replaced serial and parallel ports. It also supports plug-and-play installations and hot plugging

Plug-and-play is the ability to add and remove devices to a computer while the computer is running and have the operating

system automatically recognize the change. USB 2.0, which supports data transfer rates of 480 Mbps, has been widely used in

motherboard these days.

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.

WWiirreelleessss LLAANN –– 880022..1111bb

802.11 is a specification developed by IEEE and Wireless LAN technology, which is an interface between a wireless client and a

base station or between two wireless clients.

802.11 family includes the following specifications and with more coming:

802.11 = 1 or 2 Mbps transmission in the 2.4 GHz band, using either frequency hopping spread spectrum (FHSS) or direct

sequence spread spectrum (DSSS)).

802.11a = 54 Mbps in the 5GHz band, using orthogonal frequency division multiplexing)

802.11b (11 Mbps transmission in the 2.4 GHz band, using direct sequence spread spectrum (DSSS).
