Chapter 1. Introduction of VL6 Features

1-1. Features of This Motherboard

This motherboard is designed for Intel’s new generation of Intel® Pentium® III & Celeronprocessors. It supports the Intel® Pentium® III & Celeronprocessor, with the FC-PGA & PPGA (Plastic Pin Grid Array package) 370-pin design, up to 768MB of memory, newer super I/O, and Green PC functions.

The VL6 uses the VIA Apollo Pro 133 chipset to make the evolutionary move from PC 100 to PC 133, increasing the speed of the system and memory buses from 100 MHz to 133 MHz. It’s 133 MHz memory interface supports the wide range of PC 133 memory devices now on the market. Its 133MHz capable front-side bus delivers a clear upgrade path to the future generation of 133MHz processors.

The VL6 provides you expendability for the USB port. It can give you the maximum four USB ports to connect to USB peripherals. The additional two USB port plugs and cable KIT are an option. VL6 also has a built in AC ‘97 2.1 CODEC onboard. This CODEC has an integrated H/W Sound Blaster Pro AC ‘97 digital audio controller that can give you the best sound quality and compatibility.

The VL6 has a built in Ultra ATA/66 function. This means that it can provides speedier HDD throughput that boosts overall system performance. Ultra ATA/66 is the new standard for IDE devices. It enhances existing Ultra ATA/33 technology by increasing both performance and data integrity. This new high-speed interface doubles the Ultra ATA/33 burst data transfer rate to 66.6 Mbytes/sec. The result is maximum disc performance using the current PCI local bus environment. Another benefit is, you can connect another four IDE devices in your system either Ultra ATA/33 IDE devices or Ultra ATA/66 IDE devices. You will have more flexibility to expand your computer system.

The VL6 has one AMR slot onboard, it is called the Audio/Modem Riser (AMR) slot. The Audio/Modem Riser is an open industry-standard specification that defines a hardware scalable Original Equipment Manufacturer (OEM) motherboard riser board and interface, which supports both audio and modem functions. The specification's main objective is to reduce the baseline implementation cost of audio and modem functionality. In accordance with PC user's demands for feature-rich PCs, combined with the industry's current trend towards lower cost PCs, all of theses functions are built into the motherboard. But motherboard integration of the modem subsystem has been problematic to date, in large part due to FCC and other international telecom certification processes that may delay the introduction of a motherboard. Resolving the homologation / certification issue for modems is one of the AMR specification's key objectives.

In the future, not only OEM motherboards will have an AMR design, the AMR card will appear in the market and you can make a choice in buying this kind of card according to your budget. But your motherboard must have an AMR slot to be able to plug an AMR card. The VL6 insures this expandibility for this issue.

VL6 provides highly flexibility to users building Pentium II/III and Celeronlevel systems. It provides the option of 66/100 or 100/133MHz CPU and memory bus combinations. You can choose the different combinations and don't need to upgrade many new components to change to this motherboard.

Chapter 2. Installing the Motherboard

This VL6 motherboard not only provides all standard equipment for classic personal computers, but also provides great flexibility for meeting future upgrade demands. This chapter will introduce step by step all of the standard equipment and will also present, as completely as possible, future upgrade capabilities. This motherboard is able to support all Intel Pentium III (FC-PGA) processors and Intel Celeron(PPGA & FC-PGA) processors now on the market. (For details, see specifications in Chapter 1.)

This chapter is organized according the following features:

2-1 Installing the Motherboard to the Chassis

2-2 Installation of the Intel Pentium III (FC-PGA) & Celeron(PPGA & FC-PGA) CPU 2-3 Installing System Memory

2-4 Connectors, Headers and Switches

$$$$ Before Proceeding with the Installation $$$$

Before you install or unplug any connectors or add-on cards, please remember to turn the ATX power supply switch off (fully turn the +5V standby power off), or take the power cord off. Otherwise, you may cause the motherboard components or add-on cards to malfunction or be damaged.

User Friendly Instructions

Our objective is to enable the novice computer user to perform the installation by himself. We have attempted to write this document in a very clear, concise and descriptive manner to help overcome any obstacles you may face during installation. Please read our instructions carefully and follow them step-by-step.

2-1. Installing the Motherboard to the Chassis

Most computer chassis will have a base on which there will be many mounting holes that allows the motherboard to be securely attached and at the same time, prevents short circuits. There are two ways to attach the motherboard to the base of chassis:

!with studs

!or with spacers

Please refer to figure 2-1, which shows the studs and spacers. There may be several types, but all look like the figures below:

In principle, the best way to attach the motherboard is with studs. Only if you are unable to do this should you attach the board with

spacers. Take a careful look at the motherboard and you will see many mounting holes on it. Line these holes up with the mounting holes on the base. If the holes line up and there are screw holes this means you can attach the

User’s Manual

2-2

Chapter2

 

 

motherboard with studs. If the holes line up and there are only slots, this means you can only attach the motherboard with spacers. Take the tip of the spacers and insert them into the slots. After doing this to all the slots, you can slide the motherboard into position aligned with the slots. After the motherboard has been positioned, check to make sure everything is OK before putting the casing back on.

Figure 2-2 shows you the way to affix the motherboard using studs or spacers:

Note

If the motherboard has mounting holes, but they don’t line up with the holes on the base and there are no slots to attach the spacers, don’t worry, you can still attach the spacers to the mounting holes. Just cut the bottom portion of spacers (the spacer they may be a little hard to cut, so be careful with your hands). In this way you can still attach the motherboard to the base without worrying about short circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard PCB surface, because the circuit wire may be near by the hole. Be careful, don’t let the screw contact any the printed circuit wire or parts on the PCB that are near the fixing hole, otherwise it may damage the board or cause board malfunctioning.

2-2. Installation of the Intel® Celeron(PPGA & FCPGA) & Pentium® III (FC-PGA) processors

The Intel® Celeron(PPGA & FC-PGA) & Pentium® III (FC-PGA) package processor installation, is easy, like Socket 7 Pentium® processors before. Because it uses the “Socket 370” ZIF (Zero Insertion Force) socket, it lets you easily fix the processor on to its position firmly. Figure 2-3 shows you what the 370 socket looks like, and how to open the lever. Its pin count is more than socket 7. Therefore, a Pentium level processor cannot be inserted into socket 370.

When you raise the lever, you have to loosen the socket lock. Please raise the lever to the end, and prepare to insert the processor. Next, you need to align the processor pin 1 to the socket pin 1. If you put it in the wrong direction, you will not be able to insert the processor easily, and processor pins will not fully go into the socket. If that is the case, please change the direction, until it easily and fully inserts into the 370 socket. See Figure 2-4.

When you finish the above, push the lever down to its original position, and you should feel the lever lock up the 370 socket. You have then finished the processor installation.

2-3. Installing System Memory

This motherboard provides three 168-pin DIMM sites for memory expansion. The DIMM sockets support 1Mx64 (8MB), 2Mx64 (16MB), 4Mx64 (32MB), 8Mx64 (64MB), 16Mx64 (128MB), and 32Mx64 (256MB) or double sided DIMM modules. Minimum memory size is 8MB and maximum memory size is 768MB SDRAM. There are three Memory module sockets on the system board. (Total six banks)

In order to create a memory array, certain rules must be followed. The following set of rules allows for optimum configurations.

!The memory array is 64 or 72 bits wide. (depending on with or without parity)

!Those modules can be populated in any order.

!Supports single and double density DIMMS.

Generally, installing SDRAM modules to your motherboard is an easy thing to do. You can refer to figure 2-5 to see what a 168-pin PC100 & PC133 SDRAM module looks like.

Unlike installing SIMMs, DIMMs may be "snapped" directly into the socket. Note: Certain DIMM sockets have minor physical differences.

If your module doesn't seem to fit, please do not force it into the socket as you may damage your memory module or DIMM socket.

The following procedure will show you how to install a DIMM module into a DIMM socket.

Step 1. Before you install the memory module, please place the computer power switch in the off position and disconnect the AC power cord from your computer.

Step 2. Remove the computer’s chassis cover.

Step 3. Before touching any electronic components, make sure you first touch an unpainted, grounded metal object to discharge

Figure 2-6. Memory module installation any static electricity stored on your clothing or body.

User’s Manual

2-4

Chapter2

 

 

 

 

Step 4.

Locate your computer’s 168-pin memory expansion DIMM socket.

 

Step 5.

Insert the DIMM module into the expansion socket as shown in the illustration.

 

 

Note how the module is keyed to the socket. You can refer to figure 2-6 for the

 

 

details. This insures the DIMM module will be plugged into the socket in one way

 

 

only. Firmly press the DIMM module into the DIMM socket, making certain the

 

 

module is completely seated in the DIMM socket.

 

Step 6.

Once the DIMM module has been installed, the installation is complete and the

 

 

computer’s cover can be replaced. Or you can continue to install other devices and

 

 

add-on cards that are mentioned in the following section.

 

 

 

 

 

Note

When you install a DIMM module fully into the DIMM socket, the eject tab should be locked into the DIMM module very firmly and fit into its indention on the both sides.

You are hard to make different from its outside look between PC100 and PC133 SDRAM module, the only way you can identify them is to see the sticker on the RAM module. The sticker will show you the RAM module is which kind structure module.

2-4. Connectors, Headers and Switches

Inside the case of any computer several cables and plugs have to be connected. These cables and plugs are usually connected one-by-one to connectors located on the motherboard. You need to carefully pay attention to any connection orientation the cables may have and, if any, notice the position of the first pin of the connector. In the explanations that follow, we will describe the significance of the first pin.

We will show you all of the connectors, headers and switches here, and tell you how to connect them. Please pay attention and read the entire section for necessary information before attempting to finish all of the hardware installation inside the computer chassis.

Figure 2-7 shows you all of the connectors and headers that we’ll discuss in the next section, you can use this diagram to visually locate each connector and header we describe.

All connectors, headers and switches mentioned here, will depend on your system configuration. Some features you may (or may not) have and need to connect or configure depending on the peripheral. If your system doesn't have such add-on cards or switches you can ignore some special feature connectors.

Chapter2

 

 

 

 

 

 

(14) FDC1 Connector

This 34-pin connector is called the “floppy disk drive connector”. You can connect a 360K, 5.25”, 1.2M, 5.25”, 720K, 3.5’’, 1.44M, 3.5” or 2.88M, 3.5” floppy disk drive, you can even connect a 3 Mode floppy disk drive (it’s a 3 1/2” drive used in Japanese computer systems).

A floppy disk drive ribbon cable has 34 wires and two connectors to provide the connection of two floppy disk drives. After connecting the single end to the FDC1, connect the two connectors on the other end to the floppy disk drives. In general, people

only install one floppy disk drive on their computer system.

Note

A red mark on a wire typically designates the location of pin 1. You need to align the wire pin 1 to the FDC1 connector pin 1, then insert the wire connector into the FDC1 connector.

(15) IDE1 and IDE2 Connectors

An IDE hard disk drive ribbon cable has 40 wires and two connectors to provide a connection for two IDE hard disk drives. After connecting the single end to the IDE1 (or IDE2), connect the two connectors on the other end to the IDE hard disk drives (or CD-ROM drive, LS-120, etc.).

Before you install a hard disk, there are some things you need to be aware of:

“Primary” refers to the first connector on the motherboard, that is, the IDE1 connector on the motherboard.

“Secondary” refers to the second connector on the motherboard, that is, the IDE2 connector on the motherboard.

Two hard disks can be connected to each connector:

The first HDD is referred to as the “Master”, the second HDD is referred to as the “Slave”.

For performance issues, we strongly suggest you not to install CD-ROM drive on the same IDE channel with hard disk. Otherwise, the system performance on this channel may drop. (For dropping how much is depending on your CD-ROM drive performance.)

Note

!The Master or Slave status of the hard disk drive is set on the hard disk itself. Please refer to the hard disk drive user’s manual.

!A red mark on a wire typically designates the location of pin 1. You need to align the wire pin 1 to the FDC1 connector pin 1, then insert the wire connector into the FDC1 connector.

The VL6 supports the Ultra ATA/66 (Also known as Ultra DMA/66) specification. It enhances existing Ultra ATA/33 technology by increasing both performance and data integrity. This new high-speed interface doubles the Ultra ATA/33 burst data transfer rate to 66.6 Mbytes/sec. The result is maximum disc performance using the current PCI local bus environment. Figure 2-10 shows you the difference between the Ultra ATA/33 and Ultra ATA/66 Conductor Cable.

Figure 2-10. The difference between Ultra ATA/33 and Ultra ATA/66 Conductor Cables

Figure 2-11 shows you a photo of an Ultra ATA/66 Conductor Cable. An Ultra ATA/66-capable cable is a 40-pin, 80-conductor cable with a black connector on one end, a blue connector on the other end and a gray connector in the middle. In addition, line 34 on the cable should be notched or cut (this may be difficult to see).

Figure 2-11. Photo of an

Ultra ATA/66 Conductor

Ultra ATA/66 is backwards compatible with all Ultra ATA/33 systems, but it will be limited in its transfer mode to the Ultra ATA/33 (Ultra DMA Mode 2 - 33 Mbytes/sec) or PIO Mode 4 (16.6 Mbytes/sec). Ultra ATA/66 hard drives are 100 percent backward compatible with both Ultra ATA/33 and DMA and with existing ATA (IDE) hard drives, CD-ROM drives, and host systems. The Ultra ATA/66 protocol and commands are designed to be compatible with existing ATA (IDE) devices and systems. Although a new 40-pin, 80-conductor cable is required for Ultra ATA/66, the chip set pin connector remains the same at 40. Hard drives that support Ultra ATA/66 also support Ultra ATA/33 and legacy ATA (IDE) specifications.

There are four requirements for attaining Ultra ATA/66: *The drive must support Ultra ATA/66.

*The motherboard and system BIOS (or an add-in controller) must support Ultra ATA/66.

*The operating system must support Direct Memory Access (DMA); Microsoft Windows 98 and Windows 95B (OSR2) support DMA.

*The cable must be an 80-pin conductor. The length should not exceed 18 inches. If all of the above requirements are met, you can enjoy the Ultra ATA/66 features of your computer system.

How to install the Ultra ATA/66 Cable Assembly:

% The BLUE connector MUST be plugged into the motherboard or your system will not work.

% Each connector on the Ultra ATA/66 cable assembly has a small polarization tab centrally located on the body of the plastic. This fits into the matching slot on the mating plugs on the motherboard and the drives, thus assuring positive mating (pin #1 to pin #1)

% The red line on the cable should be aligned with pin #1. On the drives this will result in the red line facing the power connector. Attach the BLUE connector to

the appropriate 40 pin IDE plug on the motherboard.

%Attach the BLACK connector to the mating plug on the master hard drive. Attach the GREY connector to the mating plug on the slave drive (secondary hard drive, CD-ROM, or tape drive). Please refer figure 2-12.

Introduction of the BIOS

Chapter 3. Introducing the BIOS

The BIOS is a program located on a Flash Memory chip on the motherboard. This program will not be lost when you turn the computer off. This program is also referred to as the boot program. It is the only channel the hardware circuit has to communicate with the operating system. Its main function is to manage the setup of the motherboard and interface card parameters, including simple parameters such as time, date, hard disk drive, as well as more complex parameters such as hardware synchronization, device operating mode, CPU SOFT MENUII features and setup of CPU speed. The computer will operate normally, or will operate at its best, only if all of these parameters are correctly configured through the BIOS.

&Don’t change the parameters inside the BIOS unless you fully understand their meanings and consequences

The parameters inside the BIOS are used to setup the hardware synchronization or the device-operating mode. If the parameters are not correct, they will produce errors, the computer will crash, and sometimes you will even not be able to boot the computer after it has crashed. We recommend that you do not change the parameters inside the BIOS unless you are very familiar with them. If you are not able to boot your computer anymore, please refer to the section “Erase CMOS data” in Chapter 2.

When you start the computer, the BIOS program controls it. The BIOS first operates an auto-diagnostic test called POST (Power On Self Test) for all of the necessary hardware. It then configures the parameters of the hardware synchronization, and detects all of the hardware. Only when these tasks are completed does it give up control of the computer to the program to the next level, which is the operating system (OS). Since the BIOS is the only channel for hardware and software to communicate, it is the key factor for system stability, and in insuring that your system performs at its best. After the BIOS has achieved the auto-diagnostic and auto-detection operations, it will display the following message:

PRESS DEL TO ENTER SETUP

The message will be displayed for three to five seconds, if you press the <Del> key, you will access the BIOS Setup menu. At that moment, the BIOS will display the following screen:

Figure 3-1. CMOS Setup Utility

In the BIOS Setup main menu of Figure 3-1, you can see several options. We will explain these options step by step in the following pages of this chapter, but let us first see a short description of the function keys you may use here:

!Press Esc to quit the BIOS Setup.

!Press ↑↓←→ (up, down, left, right) to choose, in the main menu, the option you want to confirm or to modify.

!Press F10 when you have completed the setup of BIOS parameters to save these parameters and to exit the BIOS Setup menu.

!Press Page Up/Page Down or +/- keys when you want to modify the BIOS parameters for the active option.

Computer Knowledge: CMOS Data

Maybe you have heard somebody saying that his or her CMOS DATA was lost. What is the CMOS? Is it important? The CMOS is the memory used to store the BIOS parameters that you have configured. This memory is passive. You can read its data, and you can also store data in it. But this memory has to be powered by a battery, in order to avoid any loss of its data when the computer is turned off. Since you may have to change the CMOS battery when it is out of power and if doing so, you will loose all CMOS data, therefore, we recommend that you write down all the parameters of your hardware, or to put a label with these parameters on your hard disk.

3-1. CPU Setup [SOFT MENUII]

The CPU can be setup through a programmable switch (CPU SOFT MENUII), that replaces the traditional manual hardware configuration. This feature allows the user to more easily complete the installation procedures. You can install the CPU without configuring any jumpers or switches. The CPU must be setup according to its specifications.

In the first option, you can press <Enter> at any time to display all the items that can be chosen for that option.

$$$$ Warning $$$$

The wrong settings of the multiplier and external clock in certain circumstances may cause CPU damage. Setting the working frequency higher than the PCI chipset or processor specs, may cause abnormal memory module functioning, system hangs, hard disk drive data lose, abnormal functioning of the VGA card, or abnormal functioning with other add-on cards. Using non-specification settings for your CPU is not the intention of this explanation. These should be used for engineering testing, not for normal applications.

If you use non-specification settings for normal operation, your system may not be stable, and may effect system reliability. Also, we do not guarantee the stability and compatibility for settings that are not within specification, and any damage of any elements on the motherboard or peripherals, is not our responsibility.

Introduction of the BIOS

3-5

 

 

Normally, we do not recommend that you use the “User Define” option to setup CPU speed and multiplier factors. This option is for setup of future CPUs whose specifications are still unknown. The specifications of all present CPUs are included in the default settings. Unless you are very familiar with all CPU parameters, it is very easy to make mistakes when you define the external clock and the multiplier factor by yourself.

Solution in case of booting problem due to invalid clock setup:

Normally, if the CPU clock setup is wrong, you will not be able to boot. In this case, turn the system off then on again. The CPU will automatically use its standard parameters to boot. You can then enter the BIOS Setup again and set up the CPU clock. If you can’t enter the BIOS setup, you must try turning the system on a few times (3~4 times) or press “INSERT“ key when turning on and the system will automatically use its standard parameters to boot. You can then enter BIOS SETUP again and set up the new parameters.

When you change your CPU:

This motherboard has been designed in such a way that you can turn the system on after having inserted a CPU in the socket without having to configure any jumpers or DIP switches. But if you change your CPU, normally you just have to turn off the power supply, change the CPU and then, set up the CPU parameters through SOFT MENUII. However, if the new CPU is slower than the old one (and is same brand and type), we offer you two methods to successfully complete the CPU change operation.

Method 1: Setup up the CPU for the lowest speed for its brand. Turn the power supply off and change the CPU. Then turn the system on again, and set up the CPU parameters through SOFT MENUII.

Method 2: Since you have to open the computer case when you change the CPU, it could be a good idea to use the CCMOS jumper to erase the parameters of the original CPU and to enter BIOS Setup to set up CPU parameters again.

Attention

After setting up the parameters and leaving the BIOS SETUP, and having verified that the system can be booted, do not press the Reset button or turn off the power supply. Otherwise the BIOS will not read correctly, the parameters will fail and you must enter SOFT MENUII again to set up the parameters all over again.

CPU Power Supply:

This option allows you to switch between CPU default and user-defined voltages.

User’s Manual

Chapter 3

 

 

CPU Default:

The system will detect the CPU type and select the proper voltage

 

automatically. When it is enabled, the option “Core Voltage” will show

 

the current voltage setting that is defined by the CPU and this will not be

 

changeable. We recommend using this CPU default setting and not

 

changing it unless the current CPU type and voltage setting can not be

 

detected or is not correct.

User Define:

This option lets the user select the voltage manually. You can change

 

values of the “Core Voltage” option lists by using the Page Up and Page

 

Down keys.

 

 

 

 

Spread Spectrum:

Two options are available: Disabled ' Enabled. The default setting is Disabled. For EMC (Electro-Magnetic Compatibility Test) testing you may need to adjust these options for optimal results, we do not recommend you change the default, except for special reasons. Some values you select may cause system instability under some situations, please be careful.

CPU Hardwired IOQ:

Two options are available: 1 Level ' 4 Level. The default setting is 4 Level. This option will effect the pipeline depth between the processor and chipset Choose level 4 to get faster performance, and level 1 to get better stability.
