2-1 User’s Manual Chapter 2. Installing the Motherboard This SL6 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 Intel Pentium III and Celeron 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 Pentium III / Celeron 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 disconnect the power cord. 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 him or herself. 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.

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 similar to 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 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:

2-3 User’s Manual 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, do not despair, you can still attach the spacers to the mounting holes. Just cut the bottom portion of the spacers (the spacers may be a little hard to cut , so mind your fingers). 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 as the circuit wire may be too near the hole. Be careful. Do not let the screw contact 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 Pentium   III CPU The installation method for the CPU is printed on the package of the retention mechanism that comes with the motherboard. You can refer to it while you install the CPU. Note: ! Installing a heat sink and cooling fan is necessary for proper heat dissipation from your CPU. Failing to install these items may result in overheating and damage of your CPU. ! Please refer to your boxed processor installation or other documentation attached with your CPU for detailed installing instructions.

This motherboard provides three 168-pin DIMM sites for memory expansion. The DIMM sockets support 8Mx64 (64MB), 16Mx64 (128MB), 32Mx64 and (256MB) DIMM modules. Minimum memory size is 64MB and maximum memory size is 512MB SDRAM. 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 Memory Module Total Memory Bank 0, 1 (DIMM1) 8MB, 16MB, 32MB, 64MB, 128MB 8MB ~ 512MB Bank 2, 3 (DIMM2) 8MB, 16MB, 32MB, 64MB, 128MB 8MB ~ 512MB Bank 4, 5 (DIMM3) 8MB, 16MB, 32MB, 64MB, 128MB 8MB ~ 512MB Total System Memory 8MB ~ 512MB Generally, installing SDRAM modules to your motherboard is an easy thing to do. You can refer to figure 2-3 to see what a 168-pin PC100 & PC133 SDRAM module looks like. 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 damaged 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. Step 2. Remove the computer’s chassis cover. Figure 2-3 PC100/PC133/VCM Module and Component Mark

2-5 User’s Manual 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. 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 2-4 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 both sides. It is difficult to differentiate between the PC100, PC133 SDRAM and VCM DRAM modules from the exterior. The only way to identify them is through the sticker on the RAM module. Figure 2-4. Memory module installation

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 2-5 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 upon 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. Figure 2-5. All Connectors and Headers for the SL6

2-7 User’s Manual ATXPR1 FAN1 FAN2 First, Let’s look at the headers that the SL6 uses, and what their functions are. (1) ATXPWR1: ATX Power Input Connector Caution If the power supply connectors are not properly attached to the ATXPR1 power supply, the power supply or add-on cards may be damaged. Attach the connector from the power supply to the ATXPR1 connector here. Remember you have to push the connector from the ATX power supply firmly into the ATXPR1 connector, ensuring that you have a good connection. Note: Watch the pin position and the orientation (2A)/(2B)/(2C): FAN1, FAN2 & FAN3 header Attach the connector from the individual CPU fan to the header named FAN1. The connector from the chassis fan should be attached to the header FAN3 and the connector from the power fan to FAN2. You must attach the CPU fan to the processor or your processor will work abnormally or may be damaged by overheating. To keep the computer’s internal temperature steady and not too high, connecting the chassis fan is imperative. Note: Watch the pin position and the orientation

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) 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, such as the PCnet Magic Packet utility or other similar utilities. Note: Watch the pin position and the orientation

2-9 User’s Manual SMB1 RT2 CD1 (5) SMB1: System Management Bus Connector This connector is reserved for system management bus (SM bus). The SM bus is a specific implementation of an I2C bus. I2C 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 (6) RT2 Thermister: The RT2 is a thermistor used to detect the system environmental temperature. It may also be called a system temperature detector. You can attach one end of the two-threaded thermal cable that comes with the motherboard to the RT2 header, then tape the other end of the thermal cable on the CPU’s heat sink. Generally speaking, the location you tape the thermistor should be as near the CPU chipset as possible and avoid having it near the CPU fan. (7) CDIN1: Internal CD-ROM Drive Audio Cable Header This header is for the internal CD-ROM drive audio cable connection. Please check your audio cable attached with the CD- ROM drive to see which type of connector you have and then plug it into this header.

This switch allows you to manually setting the front side bus speed. (1) SW1 - SW2 on, SW3 - SW4 off: This is to use the CPU default value (66 / 100 / 133MHz). (2) SW1 - SW2 off, SW8 on: This enables you to adjust CPU clock manually by SW3 - SW4. SW3 - SW4 on: 66MHz SW3 off, SW4 on: 100MHz SW3 - SW4 off: 133MHz (3) SW5 on, SW6 off: This is the default setting. (4) SW7: This is to enable or disable the On Board Codec. Set on to disable. (5) SW8: This is to set the SoftMenu or None SoftMenu. Set on to None SoftMenu. (9) CCMOS1: CMOS Discharge Jumper The jumper CCMOS discharges CMOS memory. When you install the motherboard, make sure this jumper is set for normal operation (pin 1 and 2 shorted). See figure 2-6. Figure 2-6. CCMOS1 jumper setting

2-11 User’s Manual Note 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. (10) PN1 and PN2 Headers PN1 and PN2 are for switches and indicators of the chassis’ 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 2-7 shows you the functions of PN1 and PN2. Figure 2-7. 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 7 - 8): 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.

PN1 (Pin 10 - 11): Power on Switch Header Attach the cable from the case’s front panel power switch to this header. PN1 (Pin 13-14): 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 through hardware. Note: If the 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. PN2 (Pin 9-10): Suspend LED Header Insert the two-threaded suspend LED cable into pin 9 and pin 10. If you install it in the wrong direction, the LED light will not illuminate correctly. Note: Watch the Suspend LED pin position and the orientation.

(11) 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 (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. The end attached to the longer length of ribbon should be attached to the motherboard connector.

of the wire to pin 1 of the FDC1 connector and then insert. (12) 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.). Again the connector attached to the longer ribbon length should be attached to the mobo. 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” and the second HDD is referred to as the “Slave”. ♦ For performance issues, we strongly suggest you don’t install a CD-ROM drive on the same IDE channel as a hard disk. Otherwise, the system performance on this channel may drop. (how much depends 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.

2-15 User’s Manual Figure 2-9. Photo of an Ultra ATA/66 Conductor Cable The SL6 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 2-8 shows you the different between the Ultra ATA/33 and Ultra ATA/66 Conductor Cable. Figure 2-8. The difference between Ultra ATA/33 and Ultra ATA/66 Conductor Cables Figure 2-9 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). 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.

Cable to the Motherboard *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 2-10. Figure 2-11. SL6 back panel connectors Figure 2-11 shows the SL6 back panel connectors. These connectors are for connection to outside devices to the motherboard. We will describe which devices will attach to these connectors below.

2-17 User’s Manual KM1 Lower: PS/2 Keyboard Connector Attach a PS/2 keyboard connector to this 6-pin Din-connector. If you use an AT keyboard, you can go to a computer store to purchase an AT to ATX converter adapter. You can then connect your AT keyboard to this connector. We suggest you use a PS/2 keyboard for best compatibility. KM1 Upper: PS/2 Mouse Connector Attach a PS/2 mouse to this 6-pin Din- connector. USB Port Connectors This motherboard provides two USB ports. Attach the USB connector from the individual device to these connectors. You can attach USB devices such as a scanner, digital speakers, monitor, mouse, keyboard, hub, digital camera, joystick etc. to one of each of the USB connectors. You must make sure your operating system supports this feature and you may need to install an additional driver for individual devices. Please refer to your device user’s manual for detailed information.

This motherboard provides one COM port. You can connect an external modem, mouse or other devices that support this communication protocol to this connector. You can decide which external device you want to connect to COM1. The COM port can only have one device connected at a time. Parallel Port Connector This parallel port is also called an “LPT” port because it usually connects to the printer. You can connect other devices that support this communication protocol, like an EPP/ECP scanner, etc.

2-19 User’s Manual Line Out, Line In and Mic In Connector Line Out connector:You can connect an external stereo speaker signal input plug to this connector, or you can connect the plug from here to the stereo audio equipment AUX signal input socket. Remember, the motherboard does not have a built in amplifier to drive the speaker. You must use a speaker that has a built in amplifier. Otherwise, you may not be able to hear any sound or only a small volume of sound from the speaker. Line In Connector: You can connect the TV adapter audio output signal, or external audio sources, like a CD walkman, video camcorder, VHS recorder audio output signal plug to this connector. Your audio software can control the input level for the line-in signal. Mic In Connector: You can connect the plug from the microphone to this connector. Do not connect other audio (or signal) sources to this connector.

You can connect your joystick, game pad, or other simulation hardware device DIN 15-pin plugs to this connector. Please refer to the further connection notes of the device’s user's manual for further detailed information. Note This chapter contains many color drawing diagram and photos, we strongly recommend you to read this chapter using the PDF file that is included on the CD. It will provide you with greater clarity.

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 MENU™ 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 not even 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 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 ensuring 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 message:

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.

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 lose all CMOS data, we recommend that you write down all the parameters of your hardware, or to put a label with these parameters on your hard disk.

The CPU can be setup through a programmable switch (CPU SOFT MENU™ 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. You can press at any time for help. Figure 3-2. CPU SOFT MENU™ 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 Celeron™ MMX processors, you can choose the following settings:

➤ ➤ ➤ ➤ User Defined $$$$ $$$$ $$$$ $$$$ Warning $$$$ $$$$ $$$$ $$$$ 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.

For starters, everything is derived from the clock generator on the motherboard. Upon boot up the CPU will give the clock generator the default value for the Front Side Bus (FSB). Once the

operating frequencies. For example: If you have a CPU rated for a 100MHz FSB, the operating frequencies for the proper values for the FSB : SDRAM : PCI for your CPU would be calculated thusly: Pentium III® CPU with 100MHz FSB running at 500MHz: 100MHz (3:3:1) (each divided by 3) (FSB) 100MHz : (SDRAM) 100MHz : (PCI) 33MHz CPU FSB value = 100MHz x 1 = 100MHz (proper FSB value for this CPU) SDRAM value = FSB 100MHz x 1 = 100MHz (proper value for PC100 RAM) PCI value = FSB 100MHz x 1/3 = 33MHz (proper value for PCI bus) So that for this example above you can see that the x1, x1, x 1/3 values in relation to the FSB can be written as 100MHz (1: 1: 1/3) Additionally, for the working value of the CPU (in this case a Pentium® III 500MHz you calculate it like this: CPU working value = FSB 100MHz x 5 = 500MHz (proper value for this CPU) Also, the AGP value is derived from the PCI value so that: AGP value = PCI value (33MHz) x 2 or (4) = 66MHz or (132MHz) (proper value for AGP bus) For a 2x AGP it works at double the speed of the PCI bus, and four times for 4x AGP. When the FSB is above 100MHz, such as 133MHz, you can choose a PCI divider of 4, again giving you the proper 33MHz value. Now, in the BIOS they do not write dividers in fractions but rather in whole integers, so that again for the 100MHz FSB example, 100MHz (1: 1: 1/3), in the table above it looks like this: 100MHz (3:3:1) But you need to remember that each value is also divided by 3 you can look at it as if it were: 100MHz (3:3:1) each divided by 3 but you can also look at it as if it were:

or 100MHz (3/3: 3/3: 1/3) each multiplied times 3 then (divided by 3) which both equal: 100MHz (3:3:1) (divided by 3) Now the final point about this table is that it does not show the necessary divider, i.e. for the 100MHz (3:3:1) example you still need to divide each by 3, even though it does not show that in the table. Accordingly, for the 66MHz (2:3:1) you will divide each by 2 and for the 138MHz (4:3:1) example you would divide each by 4. The first value in the parenthesis is the value for the CPU’s FSB, and because everything derives its working frequency from the FSB, that value must always equal 1. So for (3:3:1) you need to divide by 3, for (2:3:1) you need to divide by 2 and for (4:3:1) you need to divide by 4. So for the 100MHz (3:3:1) example in the table above, to get the working values you are taking the (3:3:1) numbers and multiplying by 3 then dividing by 3. For another example, in the table you have 138MHz (4:3:1) (divided by 4). You can look at it like this: 138MHz (1: 3/4: 1/4). Each multiplied times 4 will give you the same value as 138MHz (4:3:1). (needing to be divided by 4 again). So that for the FSB you have 4 divided by 4 giving you a value of 1, so that 138MHz will come out to 138MHz. CPU FSB value =138MHz x1=138MHz (approximate proper FSB value for this CPU) SDRAM value = FSB 138MHz x 3/4 = 103.5MHz (approximate proper value for PC100 RAM) PCI value = FSB 138MHz x 1/4 = 34.5MHz (approximate proper value for PCI bus) Giving you all the proper values (within a few MHz or so, its never exactly precise) Another way to look at it would be that for the 138MHz (4:3:1) example, you could use this “maximum number” value of 4, and then you could divide FSB value of 138MHz by 4 which equals 34.5MHz. You could then use 34.5MHz as the base number to be multiplied by the number for the components. So that:

The SDRAM working frequency will be 34.5MHz x 3 =103.5MHz. And the PCI bus working frequency will be 34.5MHz x 1 = 34.5MHz. Giving you all the proper values (within a few MHz or so, its never exactly precise.) ABIT patented technology, SoftMenu™ allows you to adjust the FSB working frequency, when you adjust the working frequency, please choose the proper values for the FSB : SDRAM : PCI for your CPU. For example: A CPU rated for 66MHz FSB ( such as Celeron™) 66MHz (2:3:1) (each divided by 2): 66MHz : 100MHz : 33MHz or a CPU rated for 100MHz FSB (such as Pentium® III Coppermine using FC- PGA) 100MHz (3:3:1) (each divided by 3) 100MHz : 100MHz : 33MHz or a CPU rated for 133MHz FSB (such as a Pentium® III Coppermine using FC-PGA) 133MHz (4:3:1) (each divided by 4) 133MHz : 100MHz : 33MHz Note: the various components and their corresponding “bus speeds” should still work fine, nonetheless going too far “out of spec” may cause system damage or malfunction. System performance will depend mainly on the quality of the components used. Note CPU bus speed above 66MHz/100MHz/133MHz supported but not guaranteed due to the PCI and chipset specs. ✏Multiplier Factor: You can choose from the following multiplier factors: ➤ 2.0 ➤ 2.5 ➤ 3.0 ➤ 3.5 ➤ 4.0 ➤ 4.5 ➤ 5.0 ➤ 5.5 ➤ 6.0 ➤ 6.5 ➤ 7.0 ➤ 7.5 ➤ 8.0 ➤ 8.5 ➤ 9.0 ➤ 9.5 ➤10.0 ➤ 10.5 ➤ 11.0 However, differences will exist because of the various brands and types available.

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. 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” 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. 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 MENU™ II. However, if the new CPU is slower than the old one (and is the 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 MENU™ 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

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 MENU™ 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. ➤ ➤ ➤ ➤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) 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.

This section 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 3-4 to check what options are available.

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.

Three settings are available: Auto, Manual and None. If you choose Auto, the BIOS will automatically check what kind of 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: Lets 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 and that is why we recommend you use this mode. Currently, the BIOS can support the INT 13h extension function, enabling the LBA mode to support hard disk drive capacities exceeding 8.4GB. ➤ ➤ ➤ ➤Large Mode: 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

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. Drive A & Drive B: If you have installed the floppy disk drive here, then you can select the type of floppy drive 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.

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.

With each item, you can press at any time to display all the options for that 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

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. CPU Level 2 Cache: This item is used to enable or to disable the CPU level 2 cache. When the external cache is enabled, it will speed up memory access, and the system will work 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. 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 enabled, the BIOS will simplify the test procedures in order to speed up the boot process. The default setting is Enabled.

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 eleven 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 are set from the above three items. 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 an FDD or not. When this item is enabled, 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.

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 Supervisor Password at main menu and then you will be asked to enter the 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

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. Delay IDE Initial (Secs): 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.

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). The only time you might consider making any changes is if you discover that data is being lost while using your system. Figure 3-5A. Chipset Features Setup Screen You can use the arrow keys to move between the items. Use , , - and Enter 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.

carefully chosen and should only be altered if data is being lost. Such a scenario might well occur if your system has mixed speed DRAM chips installed. In such a case, greater delays may be required to preserve the integrity of the data held in the slower memory chips. SDRAM CAS Latency Time: Two options are available: 2 and 3. The default setting is 3. You can select SDRAM CAS (Column Address Strobe) latency time according your SDRAM specification. SDRAM Cycle Time Tras/Trc: Two options are available: 5/7 and 6/8. The default setting is 6/8. This item controls the number of SDRAM clocks (SCLKs) used per access cycle. SDRAM RAS-to-CAS Delay Two options are available: 2 and 3. The default setting is 3. This item lets you insert a timing delay between the CAS and RAS strobe signals, used when DRAM is written to, read from, or refreshed. Fast (2) gives faster performance; and Slow(3) gives more stable performance. This item applies only when synchronous DRAM is installed in the system. SDRAM RAS Precharge Time: Two options are available: 2 and 3. The default setting is 3. This option lets you insert a timing delay between the CAS and RAS strobe signals, used when DRAM is written to, read from, or refreshed. Fast (2) gives faster performance; and Slow (3) gives more stable performance. This item applies only when synchronous DRAM is installed in the system. System BIOS Cacheable: You can select Enabled or Disabled. The default setting is Enabled. When you select Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result. Video BIOS Cacheable: You can select Enabled or Disabled. The default setting is Enabled. Enabled allows

writes to this memory area, a system error may result. Memory Hole At 15M-16M: Two options are available: Enabled and Disabled. The default setting is Disabled. This option is used to reserve the memory block 15M-16M for ISA adapter ROM. 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. Delayed Transaction: Two options are available: Enabled and Disabled. The default setting is Enabled. Set the option to enabled or disabled PCI 2.1 features including passive release and delayed transaction for the chipset. This function is used to meet the latency of PCI cycles to or from the ISA bus. This option must be enabled to provide PCI 2.1 compliance. If you have an ISA card compatibility problem, you can try to enable or disable this option for optimal results. On-Chip Video Window Size: Three options are available: 64MB ) 32MB ) Disabled. The default setting is 64MB. This option specifies the amount of system memory that can be used by the AGP graphic data. AGP Graphics Aperture Size: Two options are available: 32M ) 64M. 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. Display Cache Frequency Two options are available: 100 Mhz and 133 Mhz. The default setting is 100 Mhz. You can choose the running speed for local memory, but if your memory module does not support the speed you choose, it may cause a system boot failure or data loss problem.

When using the onboard VGA function, you had best use the default setting. CAS# Latency: Two options are available: 2 and 3. The default setting is 3. You can select the local memory clock periods. Paging Mode Control: Two options are available: Close and Open. The default setting is Open. You can select the paging mode control to open or close. RAS-to-CAS Override: Two options are available: by CAS# LT and Override (2). The default setting is by CAS# LT. This is the display cache clock period control. RAS# Timing: Two options are available: Slow and Fast. The default setting is Fast. This item controls RAS# active to Protegra, and refresh to RAS# active delay (in local memory area). RAS# Precharge Timing: Two options are available: Slow and Fast. The default setting is Fast. This item controls RAS# precharge (in local memory area).

In this menu, you can change the onboard I/O device, I/O port address and other hardware settings. Figure 3-6A. Integrated Peripherals Menu Default Screen

Onboard IDE-1 Controller: The onboard IDE 1 controller can be set as Enabled or Disabled. The default setting is Enabled. The integrated peripheral controller contains an IDE interface with support for two IDE channels. If you choose Disabled, it will effect the settings of four items not available. For example, if you disabled the Onboard IDE-1 Controller, you will also disable the Master/Slave Drive PIO Mode and Master/Slave Drive Ultra DMA. Master/Slave Drive PIO Mode: Six options are available: Auto ) Mode 0 ) Mode 1 ) Mode 2 ) Mode 3 ) Mode 4. The four IDE PIO (Programmed Input/Output) items let you set a PIO mode (0-4) for each of the four IDE devices that the onboard IDE interface supports. Modes 0 through 4 provide successively increased performance. In Auto mode (default setting), the system automatically determines the best mode for each device. Master/Slave Drive Ultra DMA: Two options are available: Auto and Disabled. The default setting is Auto. Ultra DMA is a DMA data transfer protocol that utilizes ATA commands and the ATA bus to allow DMA commands to transfer data at a maximum burst rate of 33 MB/sec.

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 3-10. Power Management Setup Lower Screen Shot 2. Use the arrow keys to go to the item you want to configure. To change the settings, use ,,- and Enter 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 Play functions of a computer.

“Enabled” to enable ACPI functions. 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 Note: If you enable the ACPI function in the BIOS setup, the SMI function will not work. 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 3-6-1). ! Support for a front panel power and sleep mode switch. Table 3-6-2 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 3-6-1: Wake Up Device and Events The table below describes which devices or specific events can wake the computer from specific states.

The default setting is S1(POS). Generally, ACPI has six states: System S0 state, S1, S2, S3, S4, S5. S1 and S3 states are described below: The S1 (POS) State (POS means Power On Suspend): While the system is in the S1 sleeping state, its behavior is as described below: ! The processor is not executing instructions. The processor’s complex context is maintained. ! Dynamic RAM context is maintained. ! Power Resources are in a state compatible with the system S1 state. All Power Resources that supply a System Level reference of S0 are in the OFF state. ! Devices states are compatible with the current Power Resource states. Only devices which solely reference Power Resources which are in the ON state for a given device state can be in that device state. In all other cases, the device is in the D3 (off) state. ! Devices that are enabled to wake the system and that can do so from their current device state can initiate a hardware event which transitions the system state to S0. This transition causes the processor to continue execution where it left off.

cache. The S3 (STR) State (STR means Suspend to RAM): The S3 state is logically lower then the S2 state and is assumed to conserve more power. The behavior of this state is defined as follows: ! Processor is not executing instructions. The processor complex context is not maintained. ! Dynamic RAM context is maintained. ! Power Resources are in a state compatible with the system S3 state. All Power Resources that supply a System Level reference of S0, S1, or S2 are in the OFF state. ! Devices states are compatible with the current Power Resource states. Only devices which solely reference Power Resources which are in the ON state for a given device state can be in that device state. In all other cases, the device is in the D3 (off) state. ! Devices that are enabled to wake the system and that can do so from their current device state can initiate a hardware event which transitions the system state to S0. This transition causes the processor to begin execution at its boot location. The BIOS performs initialization of core functions as required to exit an S3 state and passes control to the firmware resume vector. Please see the ACPI Specification Rev. 1.0 book section 9.3.2 for more details on BIOS initialization. From the software point of view, this state is functionally the same as the S2 state. The operational difference can be that some Power Resources that could be left ON in the S2 state might not be available to the S3 state. As such, additional devices can be required to be in logically lower D0, D1, D2, or D3 state for S3 than S2. Similarly, some device wake events can function in S2 but not S3. Because the processor context can be lost while in the S3 state, the transition to the S3 state requires that the operating software flush all dirty cache to DRAM. . . . . Above information for system S0 & S3 were refer to ACPI Specification Rev. 1.0. Power Management: This item allows you to select the type (or degree) of power saving and is directly related to the following modes: 1. Suspend Mode 2. HDD Power Down There are three options for power management, three of which have fixed mode settings:

Suspend Mode: Disabled ) 1 Min ) 2 Min ) 4 Min ) 8 Min ) 12 Min ) 20 Min ) 30 Min ) 40 Min ) 1 Hour. The default setting is Disabled. HDD Power Down: Disabled ) 1 Min ) 2 Min ) 3 Min ) 4 Min ) 5 Min ) 6 Min ) 7 Min ) 8 Min ) 9 Hour ) 10 Min ) 11 Min ) 12 Min ) 13 Min ) 14 Min ) 15 Min. The default setting is Disabled. ➤Min Saving When these two saving modes are enabled, the system is set up for minimum power savings. Suspend Mode = 1 Hour HDD Power Down = 15 Min ➤Max Saving When the two saving modes are enabled, the system is set up for maximum power savings. Suspend Mode = 1 Min HDD Power Down = 1 Min Video Off Method: Three video off methods are available: "Blank Screen", "V/H SYNC + Blank" and "DPMS". The default is " V/H SYNC + Blank ". If this setting does not shut off the screen, select “Blank Screen”. If your monitor and video card support DMPS standard, select “DPMS”. Blank Screen: This option only writes blanks to the video buffer. V/H SYNC + Blank: This selection will cause the system to turn off the vertical and horizontal synchronization ports and write blanks to the video buffer. DPMS: Initial display power management signaling. Video Off In Suspend: Two options are available: Yes or No. The default setting is Yes. This item determines the manner in which the monitor is blanked.

Grant. Modem Use IRQ: You can specify the IRQ for modem use. Eight options are available: N/A ) 3 ) 4 ) 5 ) 7 ) 9 ) 10 ) 11. The default setting is N/A. Suspend Mode/HDD Power Down: These two items will be enable to change setting when item Power Management is set to User Define, theses two item will also changes as table 3-6-3 below. Table 3-6-3: Power Management Settings Power Management Settings Items User Define Min Saving Max Saving Suspend Mode Disabled ) 1 Min ) 2 Min ) 4 Min ) 8 Min ) 12 Min ) 20 Min ) 30 Min ) 40 Min ) 1 Hour.

The default setting is Disabled. 15 Min 1 Min Soft-Off by PWR-BTTN: Two options are available: Instant-Off and Delay 4 Sec.. The default setting is Instant-Off. Pressing the power button for more than four seconds forces the system to enter the Soft-Off state when the system has "hung". Wake-Up by PCI card: Two options are available: Enabled and Disabled. Default setting is Disabled. This item can let you wake-up your computer by PCI devices. For instance, if you had installed a PCI LAN card with Wake-Up on LAN capability, then you could wake-up your computer from

the PCI card built-in hardware function to support the wake up function without special cables connected to the motherboard. Note This feature needs a specific network interface which is optional. Also your ATX power supply +5V standby power must be at least 720mA compatible. Power On by Ring: Two options are available: Enabled and Disabled. Default setting is Disabled. If you connect an external modem to the onboard serial port, the system will be turned on when a telephone ring-up occurs. USB KB Wake-Up From S3: Two options are available: Enabled and Disabled. Default setting is Disabled. CPU Thermal-Throttling This option is used during Suspend To RAM (STR) mode. It controls the CPU speed as a percentage of regular power. Options include 87.5%, 75.0%, 62.5%, 50.0%, 37.5%, 25.0%, 12.5%. The default setting is set at 62.5%. Resume by Alarm: Two options are available: Enabled and Disabled. Default setting is Disabled. The RTC alarm can turn on the system. You can set Date (of month) and Time (hour, minute, and second) when you set this item to Enabled. Reload Global Timer Events When one of the specified events occur, the count down made for entry in power saving mode goes back to zero. Since the computer will enter a power saving mode only after an inactivity delay specified (time specific for Doze, Standby and Suspend modes) and after it has no activity, during this time period, any event will cause the computer to re-count the time elapsed. Resume events are operations or signals that cause the computer to resume time counting.

Two options are available: Enabled and Disabled. The default setting is Disabled. If any primary IDE master/slave I/O activity occurs, it will cause the computer to re-count the time elapsed. ➤IDE Secondary Master / IDE Secondary Slave: Two options are available: Enabled and Disabled. Default setting is Disabled. If any secondary IDE master/slave I/O activity occurs, it will cause the computer to re-count the time elapsed. ➤ ➤ ➤ ➤FDD, COM, LPT Port: Two options are available: Enabled and Disabled. Default setting is Enabled. If any floppy disk, COM ports and Parallel port I/O activity occurs, it will cause the computer to re-count the time elapsed. ➤ ➤ ➤ ➤PCI PIRQ[A-D]#: Two options are available: Enabled and Disabled. Default setting is Disabled. If any INTA~INTD signal activity occurs, it will cause the computer to re-count the time elapsed.

Interconnect, is a system which allows I/O devices to operate at speeds nearing the speed the CPU itself uses when communicating with its own special components. This section covers some very technical items and it is strongly recommended that only experienced users should make any changes to the default settings. Figure 3-11. PnP/PCI Configurations Setup Screen Shot PNP OS Installed: Two options are available: No and Yes. Default setting is No. Device resource assigned by PnP OS or BIOS. Force Update ESCD: If you want to clear ESCD data next time you boot up, and ask the BIOS to reset the settings for the Plug & Play ISA Card and the PCI Card, select Enabled. But the next time you boot up, this option will automatically be set as Disabled.

The ESCD contains the IRQ, DMA, I/O port, memory information of the system. This is a specification and a feature specific to the Plug & Play BIOS. Resources Controlled By: Two options are available: Auto(ESCD) and Manual. Default setting is Auto(ESCD). When the setting is Auto(ESCD), the IRQ Resources and Memory Resources can not be changed. When resources are controlled manually, the IRQ Resources and Memory Resources can then be changed. Legacy ISA devices compliant with the original PC AT bus specification, requiring a specific interrupt (such as IRQ4 for serial port 1). PCI/ISA PnP devices compliant with the Plug and Play standard, whether designed for the PCI or ISA bus architecture. The Award Plug and Play BIOS has the capability to automatically configure all of the boot and Plug and Play compatible devices. If you select Auto (ESCD), The IRQ Resources item will be disabled, as the BIOS automatically assigns them. But if you have trouble in assigning the interrupt resources automatically, you can select Manual to set which IRQ and DMA are assigned to PCI/ISA PnP or legacy ISA cards. Figure 3-12 shows you the screen of IRQ resources. Each item has two options: PCI Device and Reserved. The default setting is PCI Device. PCI /VGA Palette Snoop: This option allows the BIOS to preview VGA Status, and to modify the information delivered from the Feature Connector of the VGA card to the MPEG Card. This option can solve the display inversion to black after you have used the MPEG card. PIRQ_0~PIRQ3: Eleven options are available: Auto, 3, 4, 5, 7, 9, 10, 11, 12, 14, 15. Default setting is Auto. This item allows the system to automatically specify the IRQ number for the device installed on PCI slots. Which means, the system can specify the fixed IRQ number for the device installed on the PCI slots (PCI slot 1 to PCI slot 5). This is a useful function when you want to fix the IRQ for a specific device.

re-install Windows® NT, then you can specify the IRQ for the device installed on the new computer to fit the original computer settings. Note If you specify the IRQ in this item, then you cannot specify the same IRQ to the ISA bus, otherwise, it will cause a hardware conflict. This feature is for the operating system which will record and fix the PCI configuration status, if you want to change it. For the relations between the hardware layout of PIRQ (the signals from the 810E chipset), INT# (means PCI slot IRQ signals) and devices, please refer to the table below: Signals PCI slot 1 PCI slot 6 PCI slot 2 PCI slot 3 PCI slot 4 PCI slot 5 PIRQ_0 INT A INT B INT C INT D PIRQ_1 INT B INT C INT D INT A PIRQ_2 INT C INT D INT A INT B PIRQ_3 INT D INT A INT B INT C ! Each PCI slot has four INT#s (INT A~INT D).

You can set the warning temperature for your computer system, and you can check the fan speeds and power supply voltages of your computer system. The features are useful for monitoring all the important parameters within your computer system. We call it the PC Health Status. Figure 3-13. PC Health Status Screen Shot Temperature Warning: This item lets you select the temperature at which you want the system to send out a warning message to the PC speakers of when the temperature goes beyond either limit. You can select the temperatures you want. The ranges are from 30°C / 86°F to 120°C / 248°F, default setting is 75°C / 167°F. All Voltages, Fans Speed and Thermal Monitoring: These items list the current states of the CPU and environment (using RT1 and RT2 to detect them.) temperatures as well as fan speeds (CPU fan and chassis fan). It can not be changed by the user. The following items list the voltage states of the system power. It is also unchangeable.
