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 !

The System Block Diagram Figure 1-3. System diagram of the VIA Apollo Pro 133 chipset VL6 Installing the Motherboard 2-1 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 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 Installing the Motherboard Note 2-13 ! 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 2-11 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 Figure 2-10. The difference between Ultra ATA/33 and cable should be notched or Ultra ATA/66 Conductor Cables cut (this may be difficult to see). 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: Figure 2-11. Photo of an Ultra ATA/66 Conductor *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. User's Manual 2-14 How to install the Ultra ATA/66 Cable Assembly: Chapter2 % 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) Figure 2-12. How to connect an ATA/66 Cable to the Motherboard % 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. Figure 2-13.

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 MENUTM II 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 key, you will access the BIOS Setup menu. At that moment, the BIOS will display the following screen: User's Manual 3-2 Chapter 3 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. VL6 Introduction of the BIOS 3-3 3-1. CPU Setup [SOFT MENUTM II] The CPU can be setup through a programmable switch (CPU SOFT MENUTM II), 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 at any time to display all the items that can be chosen for that option. Figure 3-2. CPU SOFT MENUTM II CPU Name Is: Intel Celeron MMX Intel Pentium III MMX CPU Operating Speed: This option sets the CPU speed. In this field, the CPU speed is indicated like this: CPU speed = External clock * Multiplier factor, select the CPU speed according the type and the speed of your CPU. For Intel Pentium® III and CeleronTM MMX processors, you can choose the following settings: 300 (66) 433 (66) 533 (66) 600 (100) 700 (66) 800 (133) 1000 (133) 333 (66) 450 (100) 533 (133) 600 (133) 700 (100) 850 (100) User Define User's Manual 366 (66) 466 (66) 550 (100) 650 (100) 733 (133) 866 (133) 400 (66) 500(66) 566 (66) 667 (66) 750 (100) 900 (100) 400 (100) 500 (100) 600 (66) 667 (133) 800 (100) 933 (133) 3-4 User defined external clock and multiplier factor: User Defined Chapter 3 $$$$ Warning $$$$ 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. Ext. Clock (PCI): 66MHz (1/2) 140MHz (1/4) 120MHz (1/3) 75MHz (1/2) 100MHz (1/3) 105MHz (1/3) 112MHz (1/3) 124MHz (1/3) 133MHz (1/4) 110MHz (1/3) 103MHz (1/3) 150MHz(1/4) 115MHz (1/3) 83MHz (1/2) Note CPU bus speed above 66MHz/100MHz/133MHz supported but not guaranteed due to the PCI, processor and chipset specs. Multiplier Factor: You can choose the following multiplier factors: 2 2.5 3 3.5 4 4.5 6.5 7 7.5 8 8.5 9 11 11.5 12 5 9.5 5.5 10 6 10.5 However, differences will exist because of the various brands and types available. Note According to CeleronTM PPGA MMX processor types, some CeleronTM PPGA MMX processors will have the multiplier factor locked and the signal disabled. In this situation, there is no way to choose a higher multiplier factor. Speed Error Hold: The default setting is "Disabled". If you change the setting to "Enabled" when the CPU speed setting is wrong, the system will hold. VL6 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 MENUTM II. 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 MENUTM II. 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 MENUTM II 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 3-6 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. VL6 Introduction of the BIOS 3-7 3-2. Standard CMOS Features Setup Menu This contains the basic configuration parameters of the BIOS. These parameters include date, hour, VGA card, FDD and HDD settings. Figure 3-3A. Standard CMOS Setup Screen Shot Date (mm:dd:yy): You can set the date in this item: month (mm), date (dd) and year (yy). Time (hh:mm:ss): You can set the time in this item: hour (hh), minute (mm) and second (ss). IDE Primary Master / Slave and IDE Secondary Master / Slave: These items have a sub-menu to let you choose further options. You can refer to figure 3-3B to check what options are available. Figure 3-3B. IDE Primary Master Setup Screen Shot User's Manual 3-8 Chapter 3 IDE HDD Auto-Detection: Press the Enter key for the BIOS to auto detect all detailed parameters of the hard disk drivers (HDD). If auto detection is successful, the correct values will be shown in the remaining items of this menu. Note ( A new IDE HDD must be first formatted, otherwise it can not read/write. The basic step in using a HDD is to make a HDD low-level format, then run FDISK, and then FORMAT the drive. Most current HDDs have already been subjected to low-level format at the factory, so you can probably skip this operation. Remember though, the primary IDE HDD must have its partition set to active within the FDISK procedure. ) If you are using an old HDD that is already formatted, auto detection can not detect the correct parameters. You may need to do a low-level format or set the parameters manually, and then check if the HDD is working. IDE Primary Master: Three settings are available: Auto, Manual and None. If you choose Auto, the BIOS will automatically check what kind hard disk you are using. If you want to set the HDD parameters yourself, make sure you fully understand the meaning of the parameters, and be sure to refer to the manual provided by the HDD manufacture to get the settings right. Access Mode: Since old operating systems were only able to support HDDs with capacities no bigger than 528MB, any hard disk with more than 528MB was unusable. AWARD BIOS features a solution to this problem: you can, according to your operating system, choose four operating modes: NORMAL ' LBA ' LARGE 'Auto. The HDD auto detection option in the sub-menu will automatically detect the parameters of your hard disk and the mode supported. Auto: Just let the BIOS detect your HDD access mode and make the decisions. Normal mode: Standard normal mode supports hard disks of up to 528MB or less. This mode directly uses positions indicated by Cylinders (CYLS), Heads, and Sectors to access data. LBA (Logical Block Addressing) mode: The earlier LBA mode can support HDD capacities of up to 8.4GB, and this mode uses a different method to calculate the position of disk data to be accessed. It translates Cylinders (CYLS), Heads and Sectors into a logical address where data is located. The Cylinders, Heads, and Sectors displayed in this menu do not reflect the actual structure of the hard disk, they are just reference values used to calculate actual positions. Currently, all high capacity hard disks support this mode, that's why we recommend you use this mode. Currently, the BIOS can support the INT 13h extension function, VL6 Introduction of the BIOS enabling the LBA mode to support hard disk drive capacities exceeding 8.4GB. Large Mode: 3-9 When the number of cylinders (CYLs) of the hard disk exceeds 1024 and DOS is not able to support it, or if your operating system does not support LBA mode, you should select this mode. Capacity: This item auto displays your HDD size. Note that this size is usually slightly greater than the size given by a disk checking program of a formatted disk. Note All the items below are available when you set the item Primary IDE Master to Manual. Cylinder: When disks are placed directly above one another along the shaft, the circular vertical "slice" consisting of all the tracks located in a particular position is called a cylinder. You can set the number of cylinders for a HDD. The minimum number you can enter is 0, the maximum number you can enter is 65536. Head: This is the tiny electromagnetic coil and metal pole used to create and read back the magnetic patterns on the disk (also called the read/write head). You can configure the number of read/write heads. The minimum number you can enter is 0, the maximum number you can enter is 255. Precomp: The minimum number you can enter is 0, the maximum number you can enter is 65536. Warning Setting a value of 65536 means no hard disk exists. Landing Zone: This is a non-data area on the disk's inner cylinder where the heads can rest when the power is turned off. The minimum number you can enter is 0, the maximum number you can enter is 65536. Sector: The minimum segment of track length that can be assigned to stored data. Sectors usually are grouped into blocks or logical blocks that function as the smallest units of data permit. You can configure this item to sectors per track. The minimum number you can enter is 0, the maximum number you can enter is 255. Driver A & Driver B: If you have installed the floppy disk drive here, then you can select the type of floppy drive User's Manual 3-10 Chapter 3 it can support. Six options are available: None'360K, 5.25 in. ' 1.2M, 5.25in. ' 720K, 3.5 in. ' 1.44M, 3.5 in. ' 2.88M, 3.5 in. Floppy 3 Mode Support: Four options are available: Disabled ' Driver A ' Driver B ' Both. The default setting is Disabled. 3 Mode floppy disk drives (FDD) are 3 1/2" drives used in Japanese computer systems. If you need to access data stored in this kind of floppy, you must select this mode, and of course you must have a 3 Mode floppy drive. Video: You can select the VGA modes for your video adapter, four options are available: EGA/VGA ' CGA 40 ' CGA 80 ' MONO. The default setting is EGA/VGA. Halt On: You can select which type of error will cause the system to halt. Five options are available: All Errors ' No Errors ' All, But Keyboard ' All, But Diskette ' All, But Disk/Key. You can see your system memory list in the lower right box, it shows the Base Memory, Extended Memory and total Memory size configurations in your system. It is detected by the system during boot-up procedure. VL6 Introduction of the BIOS 3-11 3-3. Advanced BIOS Features Setup Menu In each item, you can press at any time to display all the options for this item. Attention Advanced BIOS Features Setup Menu has already been set for maximum operation. If you do not really understand each of the options in this menu, we recommend you use the default values. Figure 3-4A. Advanced BIOS Features Setup Upper Screen Figure 3-4B. Advanced BIOS Features Setup Lower Screen Virus Warning: This item can be set to Enabled or Disabled, the default setting being Disabled. When this feature is enabled, if there is any attempt from a software or an application to access the boot sector or the partition table, the BIOS will warn you that a boot virus is attempting to access the hard disk. CPU Level 1 Cache: This item is used to enable or to disable the CPU level 1 cache. When the cache is set to Disabled it is much slower, so the default setting for this item is Enabled since it will speed up memory access. Some old and very poorly written programs will make the computer malfunction or crash if the system speed is too high. In this case, you should disable this feature. The default setting is Enabled. User's Manual 3-12 Chapter 3 CPU Level 2 Cache: This item is used to enable or to disable the CPU level 2 cache. When the external cache is enable, it will speed up memory access, and the system works faster. The default setting is Enabled. CPU L2 Cache ECC Checking: This item is used to enable or to disable the CPU level 2 cache ECC checking function. The default setting is Enabled. Processor Number Feature This feature can let the program read the data inside your processor. This feature only works with Intel® Pentium® III processors. When you install a Pentium® III processor on your motherboard and boot your system, this item will appear in the BIOS. Two items will be available: Enabled and Disabled. When you choose Enabled, the specific program can read your processor's serial number. When you choose Disabled it will not allow the program to read your processor's serial number. The default setting is Enabled. Quick Power On Self Test: After the computer has been powered on, the BIOS of the motherboard will run a series of tests in order to check the system and its peripherals. If the Quick Power on Self-Test feature is enable, the BIOS will simplify the test procedures in order to speed up the boot process. The default setting is Enabled. First Boot Device: When the computer boots up, the BIOS attempts to load the operating system from the devices in the sequence selected in these items: floppy disk drive A, LS/ZIP devices, hard drive C, SCSI hard disk drive or CD-ROM. There are ten options for the boot sequence that you can choose (The default setting is Floppy.): Floppy ' LS120 ' HDD-0 ' SCSI ' CDROM ' HDD-1 ' HDD-2 ' HDD-3 ' ZIP100 ' LAN ' Disabled. Second Boot Device: Description is the same as the First Boot Device, the default setting is HDD-0. Third Boot Device: Description is same as the First Boot Device, the default setting is LS/ZIP Boot Other Device: Two options are available: Enabled or Disabled. The default setting is Enabled. This setting allows the BIOS to try three kinds of boot devices that set from the above three items. VL6 Introduction of the BIOS 3-13 Swap Floppy Drive: This item can be set as Enabled or Disabled. The default setting is Disabled. When this feature is enabled, you don't need to open the computer case to swap the position of floppy disk drive connectors. Drive A can be set as drive B and drive B can be set as drive A. Boot Up Floppy Seek: When the computer boots up, the BIOS detects if the system has a FDD or not. When this item is enable, if the BIOS detects no floppy drive, it will display a floppy disk drive error message. If this item is disabled, the BIOS will skip this test. The default setting is Disabled. Boot Up NumLock Status: On: At boot up, the Numeric Keypad is in numeric mode. (Default Settings) Off: At boot up, the Numeric Keypad is in cursor control mode. Typematic Rate Setting: This item allows you to adjust the keystroke repeat rate. When set to Enabled, you can set the two keyboard typematic controls that follow (Typematic Rate and Typematic Rate Delay). If this item is set to Disabled, the BIOS will use the default setting. The default setting is Enabled. Typematic Rate (Chars/Sec): When you press a key continuously, the keyboard will repeat the keystroke according to the rate you have set (Unit: characters/second. Eight options are available: 6 ' 8 ' 10 ' 12 ' 15 ' 20 ' 24 ' 30 ' Back to 6. The default setting is 30. Typematic Delay (Msec): When you press a key continuously, if you exceed the delay you have set here, the keyboard will automatically repeat the keystroke according to a certain rate (Unit: milliseconds). Four options are available: 250 ' 500 ' 750 ' 1000 ' Back to 250. The default setting is 250. Security Option: This option can be set to System or Setup. The default setting is Setup. After you have created a password through PASSWORD SETTING, this option will deny access to your system (System) or modification of computer setup (BIOS Setup) by unauthorized users. SYSTEM: When you choose System, a password is required each time the computer boots up. If the correct password is not given, the system will not start. SETUP: When you choose Setup, a password is required only when accessing the BIOS Setup. If you have not set a password in the PASSWORD SETTING option, this option is not available. To disable security, select Set Password at main menu and then you will be asked to enter password. Do not type anything and just press the Enter key and it will disable security. Once security is disabled, the system will boot and you can enter the BIOS setup menu freely User's Manual 3-14 Notice Chapter 3 Don't forget your password. If you forget the password, you will have to open the computer case and clear all information in the CMOS before you can start up the system. But by doing this, you will have to reset all previously set options. OS Select For DRAM > 64MB: When the system memory is bigger than 64MB, the communication method between the BIOS and the operating system will differ from one operating system to another. If you use OS/2, select OS2; if you are using another operating system, select Non-OS2. The default setting is Non-OS2. Report No FDD For WIN 95: When using Windows® 95 without a floppy drive, please set this item to Yes. Otherwise, set it to No. The default setting is No. Video BIOS Shadow: This option is used to define whether the BIOS on the video card uses the shadow feature or not. You should set this option to Enabled, otherwise the display performance of the system will greatly decrease. Shadowing address ranges: This option allows you to decide if the ROM BIOS area of an interface card at a specific address uses the shadow feature or not. If you have no interface card using this memory block, don't enable this option. You have six address ranges you can select: C8000-CBFFF Shadow, CC000-CFFFF Shadow, D0000-D3FFF Shadow, D4000-D7FFF Shadow, D8000-DBFFF Shadow, DC000-DFFFF Shadow. Computer Knowledge: SHADOW What is the SHADOW? The BIOS of standard video or interface cards is stored in ROM, and it is often very slow. With the Shadow feature, the CPU reads the BIOS on the VGA card and copies it into RAM. When the CPU runs this BIOS, the operation is speeded up. Delay IDE Initial (Sec): This item is used to support some old models or special types of hard disks or CD-ROMs. They may need a longer amount of time to initialize and prepare for activation. Since the BIOS may not detect those kinds of devices during system booting. You can adjust the value to fit such devices. Larger values will give more delay time to the device. The minimum number you can enter is 0, the maximum number you can enter is 15. The default setting is 0. For best system performance, we strongly suggest you to set it to 0. VL6 Introduction of the BIOS 3-15 3-4. Advanced Chipset Features Setup Menu The Chipset Features Setup Menu is used to modify the contents of the buffers in the chipset on the motherboard. Since the parameters of the buffers are closely related to hardware, if the setup is not correct or is false, the motherboard will become unstable or you will not be able to boot up. If you don't know the hardware very well, use default values (i.e. use the LOAD SETUP DEFAULTS option). Figure 3-5A. Advanced Chipset Features Setup Upper Screen Figure 3-5B. Advanced Chipset Features Setup Lower Screen You can use the arrow keys to move between the items. Use PgUP, PgDn, + or - key to change the values. When you have finished setting up the chipset, press ESC to go back to the main menu. Note The parameters in this screen are for system designers, service personnel, and technically competent users only. Do not reset these values unless you understand the consequences of your changes. Bank 0/1, 2/3, 4/5 DRAM Timing: The DRAM timing of Bank 0/1, 2/3, 4/5 in this field is set by the motherboard manufacturer, depending on whether memory module preset. For end users, we do not suggest that you to change the setting. Except when you actually know what kind memory module you use. The Choice: SDRAM 10ns ' SDRAM 8ns ' Normal ' Medium ' Fast ' Turbo ' Back to SDRAM 10ns. The default setting is SDRAM 10ns. User's Manual 3-16 Chapter 3 DRAM Bank Interleave: Four options are available: Auto ' Disabled ' 2-Way ' 4-Way. The default setting is Auto. Depending on your SDRAM module structure, the 4-Way setting can make the performance best. If you choose the wrong setting, the computer system will not run in a stable manner. For detailed information on your SDRAM module, please ask your SDRAM module manufacturer. Delay DRAM Read Latch: Five options are available: Auto ' No Delay ' 0.5ns ' 1.0ns ' 1.5ns. The default setting is Auto. This option can increase the DRAM signal strength to give you better compatibility for DRAM modules. SDRAM Cycle Length: Two options are available: 2 or 3. This option sets the CAS latency timing. of the DRAM system memory access cycle when SDRAM system memory is installed on the motherboard. The default setting is 3. DRAM Clock: Two options are available: Host CLK or 66 MHz. The default setting is Host CLK. This option is used to set the working speed of SDRAM same as CPU working frequency, or keep it at 66 MHz. Memory Hole: Two options are available: Disabled or 15M - 16M. The default setting is Disabled. This option is used to free up the memory block 15M-16M. Some special peripherals need to use a memory block located between 15M and 16M, and this memory block has a size of 1M. We recommend that you disable this option. Read Around Write Two options are available: Disabled or Enabled. The default setting is Disabled. This item is designed for DRAM optimization feature. If a memory read is addressed to a location whose latest write is being held in a buffer before being written to memory, the read is satisfied through the buffer contents, and the read is not sent to the DRAM Concurrent PCI/Host Two options are available: Disabled or Enabled. The default setting is Disabled. When disable, CPU bus will be occupied during the entire PCI operation period. System BIOS Cacheable: Two options are available: Disabled or Enabled. The default setting is Disabled. When you select Enabled, you get faster system BIOS executing speed via the L2 cache. VL6 Introduction of the BIOS 3-17 Video RAM Cacheable: Two options are available: Disabled or Enabled. The default setting is Disabled. When you select Enabled, you get faster video RAM executing speed via the L2 cache. You must check your VGA adapter manual to find out if any compatibility problems will occur. AGP Aperture Size: Six options are available: 16M ' 32M ' 64M ' 128M ' 256M ' Back to 16M. The default setting is 64M. This option specifies the amount of system memory that can be used by the AGP device. The aperture is a portion of the PCI memory address range dedicated for graphics memory address space. Host cycles that hit the aperture range are forwarded to the AGP without any translation. See www.agpforum.org for AGP information. AGP-2X Mode: Two options are available: Disabled or Enabled. The default setting is Enabled. If you use the older AGP adapter that does not support AGP 2X mode, you need to set this item to Disabled. CPU to PCI Write Buffer: Two options are available: Disabled or Enabled. The default setting is Enabled. When enabled, up to four words of data can be written to the PCI bus without interrupting the CPU. When disabled, a write buffer is not used and the CPU read cycle will not be completed until the PCI bus signals that it is ready to receive the data. Because the CPU speed running faster than PCI bus, the CPU must wait as the PCI bus receives data before starting each write cycle. PCI Dynamic Bursting: Two options are available: Disabled or Enabled. The default setting is Enabled. When Enabled, every write transaction goes to the write buffer. Burstable transactions then burst on the PCI bus and nonburstable transactions don't. Which means, when you set to disabled, if the write transaction is a burst transaction, the information go to the write buffer and burst transfers are perform on the PCI bus later. If the transaction is not a burst transaction, PCI write will occur immediately. (it will active after a write buffer flush) PCI Master 0 WS Write: Two options are available: Disabled or Enabled. The default setting is Enabled. When Enabled, writes to the PCI bus are executed with zero wait states (immediately), when PCI bus is ready to receive data. If disabled , the system will wait one state before data is written to the PCI bus. PCI Delay Transaction: Two options are available: Disabled or Enabled. The default setting is Enabled. The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select Enabled to support compliance with PCI specification version 2.1. User's Manual 3-18 Chapter 3 PCI#2 Access #1 Retry: Two options are available: Disabled or Enabled. The default setting is Enabled. This item allows you enable/disable the PCI #2 Access #1 Retry. When you set the PCI#2 Access#1 to Enabled, the AGP bus will attempt to access the PCI bus at a limited time period before being disconnected. When you set it to Disabled, the AGP bus will try to access the PCI bus until it successfully accesses the PCI bus. AGP Master 1 WS Write: Two options are available: Disabled or Enabled. The default setting is Disabled. This implements a single delay when writing to the AGP Bus. When you set it to Disabled, twowait states are used by the system, allowing for greater stability. AGP Master 1 WS Read: Two options are available: Disabled or Enabled. The default setting is Disabled. This implements a single delay when reading to the AGP Bus. By default, two-wait states are used by the system, allowing for greater stability. OnChip Sound: Two options are available: Disabled or Enabled. The default setting is Enabled. Because this motherboard had built-in the Audio CODEC, so we set this item to Auto. If you want to use the other sound card with this motherboard, you have to disable this item. OnChip Modem: Two options are available: Disabled or Enabled. The default setting is Enabled. As this motherboard can use the modem riser card, you need to set it to "Enabled" in order to auto detect the device. If you want to use the other internal modem card with this motherboard, you have to disable this item. Memory Parity/ECC Check: Two options are available: Disabled or Enabled. The default setting is Disabled. This item can allow BIOS to check memory is parity/ECC module or not. VL6 Introduction of the BIOS 3-19 3-5.

(Default) Disabled: If you encounter the problem of using Ultra DMA devices, you can try to Disable this item. PIO MODE 0~4 reflects the IDE device data transfer rate. The higher the MODE value is, the better is the IDE device data transfer rate. But it does not mean that you can select the highest MODE value just as you like, you first have to be sure that your IDE device supports this MODE, otherwise the hard disk will not be able to operate normally. IDE Prefetch Mode: Two options are available: Disabled or Enabled. The default setting is Enabled. The onboard VL6 Introduction of the BIOS 3-21 IDE drive interfaces supports IDE prefetching, for faster drive accesses. If you install a primary and/or secondary add-in IDE interface, set this field to Disabled if the interface does not support prefetching. Init Display First: Two options are available: PCI Slot or AGP. The default setting is AGP. When you install more than one display cards, you can choose either a PCI display card (PCI Slot) or an AGP display card (AGP) to activate the display boot-up screen. If you only installed one display card, the BIOS will detect which slot (AGP or PCI) you installed it, in then everything will be take care of by the BIOS. USB Controller: Two options are available: Disabled or Enabled. The default setting is Enabled. This should be enabled if your system has a USB installed on the system board and you wish to use it. Even when so equipped, if you add a higher performance controller, you will need to disable this feature. If you choose disable this item, the "USB Keyboard Support" item will disappear in Chipset Features Setup menu. USB Keyboard Support: Two options are available: BIOS and OS. The default setting is OS. If your operating system supports a USB keyboard, please set it to OS. Only in some situations, such as in a pure DOS environment that does not support a USB keyboard, should you set it to BIOS. IDE HDD Block Mode: This item can be set as Enabled or Disabled. Most of new hard disk drives (IDE drives) support multi-sector transfers. This feature speeds up hard disk drive access performance and reduces the time necessary to access data. When this item is enabled, the BIOS will automatically detect if your hard disk drive supports this feature or not, and will choose the right settings for you. (The default is Enabled) Onboard FDD Controller: Two options are available: Disabled or Enabled. The default setting is Enabled. This is set to Enabled or Disabled the Onboard FDD Controller. If you add a higher performance controller, you will need to disable this feature.

When you select the item HPSIR or ASKIR, then the following two items will appear. IR Function Duplex: Two options are available: Half or Full. The default setting is Half. Select the value required by the IR device connected to the IR port. Full-duplex mode permits simultaneous two-direction transmission. Half-duplex mode permits transmission in one direction only at a time. TX, RX inverting enable: Four options are available: No, Yes ' Yes, No ' Yes, Yes ' No, No. This item allows you to determine the active of RxD, TxD. Note The setting for item "TX, RX inverting", also called "RxD, TxD Active", allows you to determine the activity of RxD, TxD. We set it fixed to "No, Yes". If your motherboard BIOS uses `Hi' and `Lo' to represent this item, you should set it to the same setting as the VL6. This means that you should set it to "Hi, Lo" in order to match the transfer and receiving speed. If you fail to do so, you will not get an IR connection between the VL6 and the other computer. Onboard Parallel Port: Four options are available: 378/IRQ7 ' 278/IRQ5 ' Disabled ' 3BC/IRQ7. The default setting is 378/IRQ7.

Select Normal unless you are certain your hardware and software both support EPP or ECP mode. According your select the following items will separate show up. ECP Mode Use DMA: When the mode selected for the onboard parallel port is ECP or ECP/EPP, the DMA channel selected can be Channel 1 or Channel 3. Parallel Port EPP Type: Two options are available: EPP1.7 ' EPP1.9. The default setting is EPP 1.9. When the mode selected for the parallel port mode is EPP, the two EPP version options are available. VL6 Introduction of the BIOS 3-23 3-6. Power Management Setup Menu The difference between Green PCs and traditional computers is that Green PCs have a power management feature. With this feature, when the computer is powered on but inactive, the power consumption is reduced in order to save energy. When the computer operates normally, it is in Normal mode. In this mode, the Power Management Program will control the access to video, parallel ports, serial ports and drives, and the operating status of the keyboard, mouse and other device. These are referred to as Power Management Events. In cases where none of these events occur, the system enters the power saving mode. When one of the controlled events occurs, the system immediately returns to normal mode and operates at its maximum speed. Power saving modes can be divided into three modes according to their power consumption: Doze Mode, Standby Mode, and Suspend Mode. The four modes proceed in the following sequence: Normal Mode ===> Doze Mode ===> Standby Mode ===> Suspend Mode The system consumption is reduced according the following sequence: Normal > Doze > Standby > Suspend 1. In the Main Menu, select "Power Management Setup" and press "Enter". The following screen is displayed: Figure 3-7A. Power Management Setup Main Menu 2. Use the arrow keys to go to the item you want to configure. To change the settings, use PgUP, PgDn, + or - key. 3. After you have configured the Power Management feature, press Esc to go back to the Main Menu. We are now going to briefly explain the options in this menu: ACPI Function (Advanced Configuration and Power Interface): ACPI gives the operating system direct control over the power management and Plug and User's Manual 3-24 Play functions of a computer. Chapter 3 If you want ACPI functions to work normally, you should notice two things. One is your operating system must support ACPI, as of now only Microsoft® Windows® 98 supports these functions. The second thing is that all devices and add-on cards in your system, must fully support ACPI, both hardware and software (drivers). If you want to know if your devices or add-on cards support ACPI or not, please contact the device or add-on card manufacture for more information. If you want to know more about ACPI specifications, please go to the address below for more detailed information: http://www.teleport.com/~acpi/acpihtml/home.htm ACPI requires an ACPI-aware operating system. ACPI features include: ! Plug and Play (including bus and device enumeration) and APM functionality normally contained in the BIOS. ! Power management control of individual devices, add-in cards (some add-in cards may require an ACPI-aware driver), video displays, and hard disk drives. ! A Soft-off feature that enables the operating system to power off the computer. ! Support for multiple wake up events (see Table 3-1). ! Support for a front panel power and sleep mode switch. Table 3-2 describes the system states based on how long the power switch is pressed, depending on how ACPI is configured with an ACPI-aware operating system. Note If you enable the ACPI function in the BIOS setup, the SMI switch function will not work. System States and Power States Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state. Table 3-1: Wake Up Device and Events The table below describes which devices or specific events can wake the computer from specific states. These device/events can wake up the computer......

The default setting is Disable. If the system has not accessed data on the hard disk drive during the specified time period, the engine of the HDD will stop in order to save electricity. You can set 1 to 15 minutes or select Disable according to your use of the HDD. Doze Mode: Eleven items are available: Disabled ' 1 Min ' 2 Min ' 4 Min ' 6 Min ' 8 Min ' 10 Min ' 20 Min ' 30 Min ' 40 Min ' 1 Hour ' Back to Disable. The default setting is Disable. When the setting selected for "Power Management" is "User Define", you can define for this mode any delay from 1 minute to 1 hour. If no power management event occurs during this time period, meaning that the computer is inactive during this period, the system will enter the Doze power saving mode. If this mode is disabled, the system will enter the next mode in the sequence (suspend mode). Suspend Mode: Eleven items are available: Disabled ' 1 Min ' 2 Min ' 4 Min ' 6 Min ' 8 Min ' 10 Min ' 20 Min ' 30 Min ' 40 Min ' 1 Hour ' Back to Disable. The default setting is Disable. When the setting selected for "Power Management" is "User Define", you can define for this mode any delay from 1 minute to 1 hour. If no power management event occurs during this time period, meaning the computer is inactive during this period, the system will enter the Suspend power saving mode. The CPU stops working completely. If this mode is disabled, the system will not enter the suspend mode. Min Saving When these two saving modes are enabled, the system is set up for minimum power savings. Doze Mode = 1 Hour Suspend Mode = 1 Hour Max Saving When the two saving modes are enabled, the system is set up for maximum power savings. Doze Mode = 1 Min Suspend Mode = 1 Min PM Control by APM: Power Management is completely controlled by the APM. Two options are available: Yes or No. The default setting is Yes.
