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: http://english.aopen.com.tw/

This motherboard supports AMD® Athlon Socket 462 series CPU. Be careful of CPU orientation when you plug it into CPU

socket (with CPU Overheat Protection function implemented, the system will be automatically powered off when the

temperature of CPU reaches to 97 degree, but it works only on AthlonXP CPU).

1. Pull up the CPU socket lever and

up to 90-degree angle.

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

With AMD platform substantially keeps increasing the speed of its CPU, it inevitably led to the

annoying problem of high CPU operation temperature at the same time. In order to prevent

accidental failure of CPU fan, which could cause the burning down of the AthlonXP CPU, we, AOpen, have meticulously

developed a new technology, named, O.H.P. (Overheat Protection) Technology to protect them. Thanks to the intelligent

monitoring design of AOpen O.H.P. technology, user can now finally set their mind at ease even when fan failed to work without

fearing the possible damage of CPU.

Under the circumstances that CPU fan is running properly,

AthlonXP temperature should be way below the highest temperature limit of 97℃. However, if CPU fan accidentally

becomes malfunction or improperly installed, the CPU

temperature would rocket abruptly, and you may find your

system hang up or crying over the smoking CPU if you haven’t

installed AOpen O.H.P. previously. With AOpen O.H.P.

technology applied, the specific thermal detection pins on

AthlonXP CPU would sense voltage difference when processor

is overheated with fan failed, and the overheat protection

system would immediately send out a signal to abort your

system by cutting CPU electricity before any damage is done.

Unlike other manufacturers who use BIOS or software to

control the power supply of CPU, AOpen O.H.P. Technology is

purely hardware-controlled the minute after system boot-up,

and occupies no system resource. We are pleasant to phase in

this practical function on all AOpen AMD series motherboards to protect customer’s valuable hardware and personal data.

Over Current Protection has been popularly implemented on ATX 3.3V/5V/12V switching power supply for a while. However,

new generation CPU is able to use regulator of different voltages to transfer 12V to CPU voltage (for example, to 2.0V). This

motherboard is with switching regulator onboard that supports CPU over-current protection, and it applies to 3.3V/5V/12V power

supply for providing full line over-current protection.

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

mistake, there is still certain risk that CPU, memory, HDD, add-on cards installed on this

motherboard may be damaged because of component failure, human operating error or unknown

nature reason. AOpen cannot guaranty the protection circuit will always work perfectly.

This motherboard supports ATA6 6, ATA100 or ATA133 IDE devices. Following table lists the transfer rate of IDE PIO and DMA

modes. The IDE bus is 16-bit, which means every transfer is two bytes. As the hard drive industry introduces faster and higher

capacity hard drives, the current Ultra ATA/100 interface causes a data bottleneck between the drive and the host computer.

To avoid this problem, hard disk manufacturers have introduced the new Ultra ATA-133 interface technology.

traditional ATA/100, ATA/133 has up to 33 percent increase in interface speed with transfer rate of 133MB/s. ATA/133

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. To make good use of this new technology and enjoy its best performance, we recommend you to pair your system with a hard disk equipped with ATA/133 technology so that your system's need for speeding on this motherboard can be satisfied.

VIA south bridge VT8237 integrates two Serial ATA host controllers that provide you an even faster

transfer rate of 150 Mbytes/second. The traditional parallel ATA specification has defined the standard

storage interface for PCs with its original speed of just 3 Mbytes/second since the protocol was

introduced in the 1980s. And the latest generation of the interface, Ultra ATA-133, has been

developed further with a burst data transfer rate of 133 Mbytes/second. However, while ATA has enjoyed an illustrious track

record, the specification is now showing its age and imposes some serious design issues on today’s developers, including a

5-volt signaling requirement, high pin count, and serious cabling headaches.

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

the growing media rate demands of PC platforms. Serial ATA is to replace parallel ATA with the compatibility with existing

operating systems and drivers, adding performance headroom for years to come. It reduces voltage and pins count

requirements and can be implemented with thin and easy to route cables.

To connect a Serial ATA disk, you have to have a 7-pin Serial ATA cable. Connect two ends of the Serial ATA cable to the Serial

ATA header on the motherboard and the disk. Like every other traditional disk, you also have to connect a power cable. Please

note that it is a jumper free implement; you don’t need to set jumpers to define a master or slave disk. When connecting two

Serial ATA disks, the system will automatically take the one connected to “Serial ATA 1” header as a master disk.

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

As the clock of CPU keeps rocketing higher and higher, it inevitably brings higher heat and

system temperature in a relative way. The way we deal with this heat problem, however, is to

spare no effort to add one fan after another to protect our pampered system, expecting these

fans could cool down our machine as much as it could.

But at the same time, we believe that same amount of users are affected terribly while working with their PC by the irritating

noises of these fans. As a matter of fact, we do not have to get our fans running at such a high speed in most cases; on the

contrary, we discovered that having your fans running at appropriate time and speed could not only reduce the noise, but also

consume the least power the system

needed, so as to prevent over-wasting

of energy resource.

Today, AOpen Motherboard is honored

to bring you a new overall solution,

SilentTek, to have your system quiet. To

collocate with hardware circuit, BIOS

and the utility under Windows,

SilentTek combined “Hardware-Status

Monitoring”, “Overheat Warning” and

“Fan Speed Control” with user-friendly

interfaces to provide you a perfect

balance between noises, system

performance and stability.

The first image you have here is the Voltage Status page. You can find current status of all voltages and set your expected margins of warning level.

You may check you system voltage from the indicating bar here.

In “Temp/Fan/Case” page, you may get aware of the current temperature of CPU and the heat inside chassis, plus checking if fans are running properly.

Of course, you may set you defaulted lowest margin fo your fans and the SilentTek would also pop up a message box and alarm you when the fan is rotating slower than this specified speed.

You may set the highest margin of your CPU and system temperature as default, and SilentTek would pop up a message box and alert you with alarm when the temperature goes beyond the specified margin.

MMKK7777MM--88XX SSeerriieess

The following page is surely the most important part of this utility. You may control the rotation speed of specific fans that you

have got the options inside in this page.

Ease-of-use and trouble free at your service.

2. Fixed FAN Control: Under this setting, a desired fan

speed is set fixed when operating.

3. Multiple Level Control: This is the most versatile

setting that allows you to set fan speed in relation to

temperature. You may find that this setting fits you

best.

4. AOpen Recommend Setting: This setting is

designed specifically for AOpen housing. A series of

lab tests were conducted under the real world

scenario to determine optimum fan speed to reduce

WWhhaatt’’ss RRAAIIDD??

Two major challenges facing the storage industry today are keeping pace with the increasing performance demands of computer

systems by improving disk I/O throughput and providing data accessibility in the face of hard disk failures.

The idea of RAID (Redundant Array of Independent Disks) was first introduced by David A. Patterson, Garth Gibson and Randy

H. Katz at the University California at Berkeley in 1988. RAID is a purpose of storing the same data in different places on

multiple hard disks and improves storage subsystem performance. The advantage of RAID is to provide better throughput

performance and/or data fault tolerance. Better performance is accomplished by sharing the workload in parallel among multiple

physical hard drives. Fault-tolerance is achieved through data redundant operation where if one (or more) drive fails or has a

sector failure, a mirrored copy of the data can be found on another drive(s).

A RAID appears to the operating system to be a single logical hard disk. The RAID controller manages how the data is stored

and accessed across the physical and logical arrays. The RAID controller help users to ensure that the operating system only

sees the logical drives and users do not need to worry about managing the complicated schema.

For optimal performance results, select identical hard drives to install in disk arrays. The drives’ matched performance allows

the array to function better as a single drive.

Warning: The Serial ATA RAID function

can be supported under Windows XP

and Windows .Net environments.

SSttrriippiinngg // SSppaann ((RRAAIIDD 00))

RAID level 0, which is the fastest drive array you can have, is a performance-oriented disk mapping method. The data in this

array gets written across a stripe or different disks for a faster transfer. This technique has striping but no redundancy of data. It

offers the best performance but no fault-tolerance. Reads and writes sector of data interleaved between multiple drives. When

any disk member fails, it affects the entire array. Performance is better than a single drive since the workload is balanced

between the array members. This array type is for high performance systems. Identical drives are recommended for

performance as well as data storage efficiency. The disk array data capacity is equal to the number of members times the

smallest member capacity. For example, one 40GB and one 60GB drives will form an 80GB (40GBx2) disk array.

RAID level 1 uses at least two duplicate hard drives and store the exact

same blocks of information between them. This is the slowest form of

fault tolerance because the data has to be replicated onto two disks at

the same time. However, this is the simplest way to provide high

reliability.

If one of the mirrored drives suffers a mechanical failure or does not

respond, the remaining drive will continue to serve and provide correct

data. If one drive has a physical sector error, the mirrored drive will

continue to function.

Due to redundancy, the drive capacity of the array is half the total drive

capacity. For example, two 40GB drives that have a combined capacity

of 80GB would have 40GB of usable storage. With drives of different

capacities, there may be unused capacity on the larger drive. RAID 1

increases cost as it takes twice as much hard drives to build our arrays.

As the name would suggest, RAID 0+1 is striping and mirroring combined. This RAID combines the best of both RAID 0 and

RAID 1. It takes a Disk stripe using two disks, and mirrors it to another set of disks for fault tolerance. Data is stripped across

several disks, each disk has partner with exactly the same data on it. You get the benefits of fast data access as in RAID 0, with

the fault tolerance of RAID 1. This configuration provides optimal speed and reliability. You need double the number of disks as

a RAID 0, half for each side of the mirror. At least 4 hard disks are needed while performing RAID 0+1. There are other RAID

configurations in addition to those described here, but these are the types most commonly used in the industry.
