Introduction of VL6 Features 1-1. Features of This Motherboard This motherboard is designed for Intel's new generation of Intel® Pentium® III & CeleronTM processors. It supports the Intel® Pentium® III & CeleronTM processor, 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 CeleronTM level 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. User's Manual 1-2 Chapter1 The VL6 has built-in hardware monitoring functions (you can refer to Appendix J for detailed information), they can monitor and protect your computer insuring a safe computing environment. The motherboard can provide high performance for servers and meets the requirements for desktop systems for multimedia in the future. 1-2. Specifications !

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 CeleronTM (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 2-2 2-3 2-4 Installing the Motherboard to the Chassis Installation of the Intel Pentium III (FC-PGA) & CeleronTM (PPGA & FC-PGA) CPU Installing System Memory 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® CeleronTM (PPGA & FCPGA) & Pentium® III (FC-PGA) processors The Intel® CeleronTM (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. VL6 Installing the Motherboard 2-3 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. Table 2-1. Valid Memory Configurations Bank Bank 0, 1 (DIMM1) Bank 2, 3 (DIMM2) Bank 4, 5 (DIMM3) Memory Module 8MB, 16MB, 32MB, 64MB, 128MB, 256MB 8MB, 16MB, 32MB, 64MB, 128MB, 256MB 8MB, 16MB, 32MB, 64MB, 128MB, 256MB Total System Memory Total Memory 8MB ~ 256MB 8MB ~ 256MB 8MB ~ 256MB 8MB ~ 768MB 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. Figure 2-5 PC100/PC133 Module and Component Mark 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 any static electricity stored on your clothing or body. User's Manual Figure 2-6. Memory module installation 2-4 Step 4. Locate your computer's 168-pin memory expansion DIMM socket. Chapter2 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. VL6 Installing the Motherboard 2-5 Figure 2-7. All Connectors and Headers for the VL6 First, Let's see the headers that VL6 uses, and what their functions are. (1) ATXPWR1: ATX Power Input Connector Caution If the power supply connectors are not properly attached to the ATXPWR1 power supply, the power supply or add-on cards may be damaged. Attach the connector from the power supply to the ATXPWR1 connector here. Remember you have to push the connector from the ATX power supply firmly to the end with the ATXPWR1 connector, insuring that you have a good connection. Note: Watch the pin position and the orientation User's Manual 2-6 Chapter2 (2A)/(2B)/(2C): FAN1, FAN2 & FAN3 header Attach the connector from the individual CPU fan to the header named FAN1, connector from the chassis fan to the header FAN3 and attach the connector from the power fan to FAN2 header. You must attach the CPU fan to the processor, or your processor will work abnormally or may be damaged by overheating. Also, if you want the computer case's internal temperature to be kept steady and not too high, you had better connect the chassis fan to reach this goal. Note: Watch the pin position and the orientation (3) IR: IR Header (Infrared) There is a specific orientation for pins 1 through 5, attach the connector from the IR KIT or IR device to the IR1 header (left row only). This motherboard supports standard IR transfer rates. Note: Watch the pin position and the orientation (4) WOM1: Wake On Modem Header If you have an internal modem adapter that supports this feature, then you can connect the specific cable from the internal modem adapter to this header. This feature lets you wake up your computer via remote control through the modem. Note: Watch the pin position and the orientation VL6 Installing the Motherboard 2-7 (5) WOL1: Wake on LAN Header If you have a network adapter that supports this feature, then you can connect the specific cable from the network adapter to this header. This feature lets you wake up your computer via remote control through a local area network. You may need a specific utility to control the wake up event, like using the PCnet Magic Packet utility or other similar utilities. Note: Watch the pin position and the orientation (6) SMB1: System Management Bus Connector This connector is reserved for system management bus (SM bus). The SM bus is a 2 2 specific implementation of an I C bus. I C is a multi-master bus, which means that multiple chips can be connected to the same bus and each one can act as a master by initiating a data transfer. If more than one master simultaneously tries to control the bus, an arbitration procedure decides which master gets priority. Note: Watch the pin position and the orientation (7A)/(7B): RT1 & RT2 Thermister: The RT1 thermistor used to detect the CPU temperature. The RT2 is a thermistor used to detect the system environmental temperature. It may also be called a system temperature detector. User's Manual 2-8 Chapter2 (8) USB2 Headers: Additional USB Plugs Header This header is for connecting the additional USB ports plugs. You can use the special USB port expend cable (option), it can provides you additional two USB plugs, you can fix these USB plugs on the back panel.

Please check your audio cable attached with the CD-ROM drive to see which type connector you have, then plug it to this header. (10) CCMOS1: CMOS Discharge Jumper Jumper CCMOS1 discharge CMOS memory. When you install the motherboard, make sure this jumper is set for normal operation (pin 1 and 2 shorted). See figure 2-8. Figure 2-8. CCMOS1 jumper setting VL6 Installing the Motherboard Note 2-9 Before you clear the CMOS, you have to first turn the power off (including the +5V standby power). Otherwise, your system may work abnormally or malfunction. (11) J1 & J2 Headers: There are two headers to use for selecting the functions for the audio CODEC and/or the AMR card. Please refer to the table below for the proper settings. AC 97 MC 97 J1 Short Open J2 1-2 Pin Short 3-4 Pin Short 1-2 Pin Short 3-4 Pin Short AC 97 & MC 97 Short For example, if you want to use the onboard audio CODEC, choose the "AC97" settings. If you want to use the modem CODEC card insertion on the AMR slot, then choose the "MC 97" setting. If you want both to work, choose the "AC 97 & MC 97" setting. (12) JP1 Header: AMR Function Selection This header can select whether the AMR card insertion on the AMR slot is primary or secondary. When you don't want to use the onboard audio CODEC, you have to set JP1 at open. The default setting is short. Remember that only when using an MC 97 card should you select the JP1 as open. Otherwise, leave it selected as short. Items JP1 short JP1 Open (13) PN1 and PN2 Headers PN1 and PN2 are for switches and indicators for the chassis's front panel, there are several functions that come from these two headers. You have to watch the pin position and the orientation, or you may cause system malfunctions. Figure 2-9 shows you the PN1 and PN2 functions of the pins. AMR Card Secondary Primary User's Manual 2-10 Chapter2 Figure 2-9. The definition of PN1 and PN2 pins PN1 (Pin 1-2-3-4-5): Power LED Headers There is a specific orientation for pins 1 through 3. Insert the three-threaded power LED cable to pins 1~3. Check to make sure the correct pins go to the correct connectors on the motherboard. If you install them in the wrong direction, the power LED light will not illuminate correctly. Note: Watch the power LED pin position and orientation. PN1 (Pin 6-7): HDD LED Header Attach the cable from the case's front panel HDD LED to this header. If you install it in the wrong direction, the LED light will not illuminate correctly. Note: Watch the HDD LED pin position and the orientation. PN1 (Pin 8-9): Power on Switch Header Attach the cable from the case's front panel power switch to this header. VL6 Installing the Motherboard 2-11 PN1 (Pin 10-11): Hardware Suspend Switch (SMI Switch) Header Attach the cable from the case's front panel suspend switch (if there is one) to this header. Use this switch to enable/disable the power management function by hardware. Note: If ACPI function in the BIOS setup is enabled, this function will not work. PN2 (Pin 1-2): Hardware Reset Switch Header Attach the cable from the case's front panel Reset switch to this header. Press and hold the reset button for at least one second to reset the system. PN2 (Pin 4-5-6-7): Speaker Header Attach the cable from the system speaker to this header. For the PN1 and PN2 pin's count-name list, please refer to table 2-2. Table 2-2.

User's Manual 2-12 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.) VL6
