Module size: Single/double-sided 64/128/256/512Mbytes or 1GBbtes. Parity: Ether parity or non-parity. 2-4 Connector and Jumper Settings Connectors are used to link the system board with other parts of the system, including the power supply, the keyboard, and the various controllers on the front-panel of the system case. The power supply connector is the last connection to be made while installing a motherboard. Before connecting the power supply, please make sure it is not connected to the power source. Note: All cables are security-proof. PW1 (ATX Power Supply Connector) The power cord leading from the system's power supply to the external power source must be the very last part connected when assembling a system. The ATX power supply provides a single 20-pin connector interface, which incorporates standard +/-5V, +/-12V, optional 3.3V and Soft-power signals. The Soft power signal, a 5V trickle supply is continuously supplied when AC power is available. When the system is in the Soft-Off mode, this trickle supply maintains the system in its minimum power state. The ATX 12V power supply has a new +12V (4-pin) and +5V/3.3V (6-pin) auxiliary power connector to enable the delivery of more +12 VDC and +5/3.3V VDC current to 8 Chapter 2 the motherboard. Power-On By Modem While in Soft-Off state, if an external modem ring-up signal occurs, the system wakes up and can be remotely accessed. You may enable this function in BIOS's Power Management Setup menu. (See section 3. 5) Blinking LED in Suspend Mode While in Suspend mode, the LED light on the front panel of your computer will flash. Suspend mode is entered by pressing the Override Power Button, pushing the Green button on your ATX case, or enabling the Power Management and Suspend Mode options in BIOS's Power Management menu. (See section 3.5) Poly-fuse Over Current Protection The poly-fuse protects the system from dangerous voltages that the system might be exposed to via the keyboard or USB connector. In case of such exposure, the poly-fuse will immediately be disconnected from the circuit, just like a normal fuse. After being disconnected for a certain period of time, the poly-fuse will return to its normal state. Then the keyboard or USB connector can function properly again. Unlike conventional fuses, the poly-fuse does not have to be replaced, relieving the user wasted time and inconvenience. CN1A (Front Panel Connector) 1. PWR-SW (Over-ride Power Button Connector) The power button on the ATX chassis can be used as a normal power switch as well as a device to activate Advanced Power Management Suspend mode. This is a power- saving mode used for saving electricity when the computer is not in use for a long period of time. The Soft-OFF by PWR-BTTN function in BIOS's Power Management Setup menu must be set to [Delay 4 Sec.] to activate this function. When the Soft-OFF by PWR-BTTN function is enabled, pushing the power button rapidly will switch the system to Suspend mode. Any occurrence of external activities 9 Chapter 2 such as pressing a key on the keyboard or moving the mouse will bring the system back to Full-On. Pushing the button while in Full-On mode for more than [4 seconds] will switch the system completely off. See Over-ride Power Button Operation diagram. 2. P-LED (Power LED Connector) The power indicator LED shows the system's power status. It is important to pay attention to the correct cable and pin orientation (i.e. Be Careful not to reverse the order of these two connectors.) 3. G-BTN/G-LED (Green Button Switch/LED Connector) Some ATX cases provide a Green button switch, which is used to put the system in Suspend mode. In Suspend mode, the power supply to the system is reduced to a trickle, the CPU clock is stopped, and the CPU core is in its minimum power state. The system is activated whenever the keyboard or mouse is touched. The system resumes in various ways as defined by Power Management Setup screen in BIOS. 4. RESET (System Reset Switch Connector) This connector should be connected to the reset switch on the front-panel of the system case. The reset switch allows you to restart the system without turning the power off. 5. SPEAKER (Speaker Connector) This 4-pin connector connects to the case-mounted speaker. 6. HD-LED (IDE Activity LED Connector) The IDE activity LED lights up whenever the system reads/writes to the IDE devices. FD1 (Floppy Connector) The motherboard provides a standard floppy disk drive connector that supports 360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types. Use this connector to connect to a floppy disk drive of 34 pins. 10 Chapter 2 IDE1 / 2 (IDE Hard-Disk Connector) The motherboard has a 32-bit Enhanced PCI IDE and Ultra ATA66/100/133 controller that provides PIO mode 0~4, Bus Master, and Ultra ATA66/100/133 function.

By choosing the Power Management Setup option from the CMOS Setup Utility menu (Figure 3-1), the screen below is displayed. This sample screen contains the manufacturer's default values for the motherboard. Figure 3-6 ACPI Suspend Type This feature allows user to select a suspend type for the operating system to turn off peripherals devices, such as CD-ROM players, when they are not in use. Power Management Option Power management allows the computer to save electricity when it is not in use by entering power-saving modes. HDD Power Down: Shuts down any IDE hard disk drives in the system after a period of inactivity as set in this user configurable field. This feature does not affect SCSI hard drives. Suspend Mode The Power Management function must not be set to disabled to enable this function. If the system runs in Standby mode and the Suspend timer expires, all devices regulated by power management will shut off and the CPU speed will be 0 MHz. 27 Chapter 3 Video Off Option This setting allows you to select the power-saving modes during which the monitor goes blank. Video Off Method This function serves as both a screen saver and power saver for monitors. See the next function, Video Off After, for setting the video timer. 1. Blank - BIOS will only blank the monitor's screen. The electricity saved in this mode is negligible and this function is only used as a screen saver to prevent screen damage while the screen is on but not in use. 2. V/H SYNC+Blank - The system turns off the vertical and horizontal synchronization ports, writes blanks to the VGA buffer and the monitor's electron gun turns off. This function requires a monitor with Green features in order to take advantage of the power saving function. If you enable this function and do not have a Green monitor, the result will be the same as if you had selected Blank. This function serves as both a screen saver and a power saver. 3. DPMS Support - Select this option if your video card supports the Display Power Management Signaling (DPMS) standard (i.e., you have a monitor that supports Green features). Use software supplied by your video subsystem to set video power management options. Modem Use IRQ If your computer has a modem use this function to tell BIOS which IRQ is being occupied by the modem card. When the system is in Green mode, the modem requires an IRQ assignment to wake up the system and perform tasks. This assignment is compliant with APM 1.2 operating systems. Soft-Off by PWRBTN When set to Delay 4 Sec., this function allows the power button to put the system in Suspend, a power-saving mode. When set to Instant-Off the Soft-Off by PWR-BTN function is disabled and the computer turns completely off when the power button is pressed.

Power On by PME / Onboard LAN When enabled, a PCI interface that receives a signal will activate the system from soft off and green mode. 10. PowerOn by Ring / WOL When enabled, a LAN/modem that receives a signal will activate the system from soft off and green mode. You should connect the modem to the COM port and turn on the resume event in green mode. 11. RTC Alarm Resume When enabled, this setting allows the system to turn back on at a designated time of the month. User must designate date of month and time of day. 12. IRQs Activity Monitoring This feature allows you to monitor a list of IRQ, Interrupt ReQuests. When an I/O device wants to gain the attention of the operating system, it signals this by causing an IRQ to occur. When the operating system is ready to respond to the request, it interrupts itself and performs the service. 29 Chapter 3 3-6 PNP/PCI Configurations This section provides IRQ and DMA setting information. By choosing the PNP/PCI Configuration option from the CMOS Setup Utility menu (Figure 3-1), the screen below is displayed. This screen contains the manufacturer's default values for the motherboard. Figure 3-7 PNP OS Installed If you want to install a PNP compatible OS (such as Windows 95) , then set it to Yes. Reset Configuration Data: If you want to reset CMOS IRQ divide hardware device, please selected to [Enabled]. Resources Controlled By When set to Manual the system BIOS will not refer to the ESCD for IRQ & DMA information. Instead, it will refer to the items in the setup menu for assigning IRQ & DMA. When set to Auto the system BIOS will refer to the ESCD for all legacy information. ESCD (Extended System Configuration Data) provides a detailed format of the configuration data structures stored in flash memory. Each data structure defines the resources used by a device or a card in the system. This includes legacy and PCI/ISA PnP devices. PCI/VGA Palette Snoop When set to [Enabled], multiple VGA devices operating on different buses can handle data from the CPU on each set of palette registers on every video device. Bit 5 of the command register in the PCI device configuration space is the VGA Palette Snoop bit (0 30 Chapter 3 is disabled). Available options are [Enabled] and [Disabled]. Assign IRQ For VGA/USB Available options: [Enabled] and [Disabled]. FDD IRQ Can Be Free This function allows user to choose if the FDD IRQ can be freed up. The default setting is [Yes] and this does not allow the IRQ to be free. 3-7 Frequency/Voltage Control By choosing the Frequency/Voltage Control option from the CMOS Setup Utility menu (Figure 3-1), the screen below is displayed. This sample screen contains the manufacturer's default values for the motherboard. Figure 3-8 Auto Detect PCI/DIMM Clk Enabling this function will auto-detect PCI/DIMM clock. Spread Spectrum Available options: [Disabled], [+/- 0.25%], [+/- 0.35], [+/- 0.45], [-0.5%]. CPU Clock It is recommended to keep the default setting for a stable system operation. 31 Chapter 3 Overclocking: This motherboard is designed to support overclocking. However, please make sure your components are able to tolerate such abnormal setting, while CPU clock speed is overclocked. Any attempt to operate beyond product specifications is not recommended. We do not guarantee the damages or risks caused by inadequate operation or beyond product specifications. 3-8 Load Fail-Safe Defaults Load Fail-Safe Defaults loads the default BIOS values directly from the CMOS Setup Utility menu (Figure3-1). If the stored record created by the setup program becomes corrupted and therefore unusable, these defaults will be loaded automatically when you turn on the computer. 3-9 Load Optimized Defaults Load Optimized Defaults loads the default system values directly from the CMOS Setup Utility menu (Figure3-1). If the stored record created by the setup program becomes corrupted and therefore unusable, these defaults will be loaded automatically when you turn on the computer. 3-10 Supervisor Password & User Password Setting There are four different variables that control password settings. The first two are located under the Security Option function in BIOS Features Setup Menu (Figure 3-1). When the Security Option function is set to Setup, a password is required to enter BIOS and change BIOS settings. When the Security Option function is set to System, a password is required to enter both BIOS and the computer's operating system (for example Windows 98) found on the boot drive. The third and fourth variables are user password and supervisor password selected in BIOS (Figure 3-1). The main purpose of separating user and supervisor is to allow only the supervisor to have control over the settings in BIOS. The user, on the other hand, is only allowed to access the computer's operating system and change the user password in BIOS. When there is no supervisor password set, the user password controls access to all BIOS settings. 32 Chapter 3 3-11 Save and Exit Setup If you select this and type [Y] (for Yes) followed by [Enter] , the values entered in the setup utilities will be recorded in the CMOS memory of the BIOS chip. 3-12 Exit Without Saving Selecting this option and pressing Y followed by [Enter] lets you exit the Setup program without recording any new values or changing old ones. 33 Chapter 4 Chapter 4 DRIVER Setup Insert the support CD that come with your motherboard into your CD-ROM driver or double-click the CD drive icon in [My computer] to open the setup screen. 4-1 VIA Service Pack Setup 1.
