* CPU Speed = Multiplier x FSB Frequency
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 in order to enable the delivery of more +12 VDC and +5/3.3V VDC current to the motherboard. Power-On By Modem While in Soft-Off state, if an external modem ring-up signal is detected, the system will be activated 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 by 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 keyboards or USB connectors. In case of such an 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 and the keyboard or USB connector can function properly again. Unlike conventional fuses, the poly-fuse will not need to be replaced, relieving the user from such inconveniences. 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 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 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 cables 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. While 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 different 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. 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. This connector is used for connecting 40 pins of ATAPI devices. IDE 1 only connects two IDE devices. (Primary Master/Slave) IDE 2 only connects two IDE devices. (Secondary Master/Slave)

Chapter 3 BIOS Setup Program
Phoenix-Award BIOS ROM has a built-in setup program that allows users to modify the basic system configuration. This information is stored in CMOS RAM so that it can retain the setup information, even when the power is turned off. To enter the Phoenix-Award BIOS setup program press [Delete] when you Power on or reboot the computer system. The primary screen as shown in Figure 3-1 is a list of the menus and functions available in the setup program. Select the desired item by your arrow keys and press enter to make the changes. Operating commands are located at the bottom of this and all other BIOS screens. When a field is highlighted, on-line help information is displayed on the right side of the screen. 3-1 Standard CMOS Setup The Standard CMOS Setup allows users to configure system components such as hard disk drive, floppy disk drive and video display as well as date, time and boot-up error signaling. This configuration menu should be changed when installing a motherboard for the first time, changing hardware in your system such as the HDD, FDD, video display, or when the CMOS data was lost or corrupted. Choose the Standard CMOS Setup option from the CMOS Setup Utility menu (Figure 3-1) to display the following screen. Date/Time Set the date and time of the system. Do not skip this function as all of your timed events such as power management, saving files, etc are based on this timer. IDE (Primary/Secondary; Master/Slave) This category identifies up to four IDE hard disk drives that have been installed in the computer. This section does not show information on other IDE devices such as CD-ROM drives or other hard drive type such as SCSI drives. Drive A Select different Floppy device Model. Available options are [None], [360K, 5-1/4 in], [1.2M, 5-1/4 in], [720k, 3-1/2 in], [1.44M, 3-1/2 in], and [2.88M, 3-1/2 in]. Video Select the type of video adapter present in your system. You can ignore this setting if you are using a VGA monitor; VGA BIOS will automatically configure this setting. Halt On When the system is powered on, BIOS performs a series of diagnostic tests called POST (Power On Self Test). This function stops the computer if BIOS detects a hardware error. You can tell BIOS to halt on all errors, no errors, or not to halt on specific errors.

3-2 Advanced BIOS Features By choosing the Advanced BIOS Features 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. Virus Warning When you set it as enabled, you receive a warning message if a program (specifically, a virus) attempts to write to the boot sector or the partition table of the hard disk drive.
Many disk diagnostic programs that access the boot sector table can trigger the virus-warning message. If you plan to run such a program, we recommend that you first disable the virus warning.
CPU Internal Cache / External Cache Cache memory is much faster than conventional DRAM system memory. These fields allow you to enable or disable the CPUs Level 1 built-in cache and Level 2 external cache. Both settings are left as Enabled to significantly increase the performance of your computer. CPU L2 Cache ECC Checking Enable this function for the CPU L2 Cache Error Checking and Correcting (ECC) operation. Quick Power On Self Test Enable this function to reduce the amount of time required to run the POST (Power On Self Test). BIOS will save time by skipping some items during POST. It is recommended that you disable this setting. Discovering a problem during boot up is better than loosing data during your work. First/Second/Third/Boot Other Device This option sets the sequence of drives BIOS attempts to boot from after POST completes. BIOS will search these drives for an operating system. Boot up Floppy Seek This is a set up check for floppy power-on after starting the computer system. Boot Up NumLock Status This function defines the keyboard's number pad as number keys or arrow keys. If it is set at [On] the number keys will be activated. If it is set at [Off] the arrow keys will be activated. Gate A20 Option This allows you to set the Gate A20 status. When set to [Fast], Gate A20 is controlled by chipset. When set to [Normal], Gate A20 is cont rolled by a specific pin from the
keyboard controller. Available options are [Fast] and [Normal]. Typematic Rate Setting When enabled, you can set the following two-typematic control items. When disabled, the keyboard controller determines keystrokes arbitrarily in your system. Typematic Rate (Chars/Sec) The typematic rate sets the rate at which characters on the screen repeat when a key is pressed and held down. Typematic Delay (Msec) The typematic delay sets how long after you press a key that a character begins repeating. Security Option The Supervisor and/or User Password functions shown in Figure 3-1 must be set to take advantage of this function. See Section 3.11 for password setting information. When the Security Option is set to System, a password must be entered to boot the system or enter the BIOS setup program. When the Security Option is set to Setup, a password is required to enter the BIOS setup program. APIC Mode In order to comply with PC2001 standard, the system is designed to run in APIC (Advanced Programmable Interrupt Controller) mode. Enabling APIC mode will expand available IRQs resources for the system. Available options are [Enabled] and [Disabled]. MPS Version Control For OS This item allows you to select which MPS (Multi-Processor Specification) version is used for the operating system. You need to select the MPS version which is supported by your operating system. To find out which version to use, consult the vendor of your operating system. Available options are [1.4] and [1.1]. OS Select For DRAM >64MB If your system's DRAM is larger than 64MB and you are running OS/2, select OS/2 as the item value. Otherwise, set the item value to Non-OS/2 for all other operating systems. HDD S.M.A.R.T. Capability This field allows you to Enable or Disable the S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) system that utilizes the internal hard disk drive monitoring technology. This parameter is normally set as Disabled because the resources used in the SMART monitoring feature may decrease the system performance.

Show POST CODE Enabling this function can show POST error code on the screen before proceeding to operating system. 3-3 Advanced Chipset Features By choosing the [Advanced Chipset Features] 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.
All of the above settings have been determined by the motherboard manufacturer and should not be changed unless you are absolutely sure of what you are doing. Explanation of the DRAM timing and chipset features setup is lengthy, highly technical and beyond the scope of this manual. Below are some brief descriptions of the functions in this setup menu.

DRAM Clock/Drive Control

1. DRAM Clock This selecting option allows you to control the DRAM speed. 2. DRAM Timing The function allows you to enable or disable the DRAM timing by SPD. It is recommended to keep the default setting for a stable system operation. 3. DRAM Burst Length / DRAM Command Rate / Write Recovery Time / tWTR It is recommended to keep the default setting for a stable system operation.
AGP & P2P Bridge Control
1. AGP Aperture Size This feature allows users to select the size of the AGP aperture. It also determines the maximum amount of system RAM that can be allocated to the graphics card for texture storage. The required AGP aperture size will become smaller as the graphics cards memory increases in size. But increase in size of the aperture does not correspond to increase in performance. It is recommend that the AGP aperture size is left around 64MB to 128 MB in size unless instructed otherwise by your video card manufacturer. 2. AGP Mode Available options: [8X], [4X]
3. AGP Driving Control The [Manual] setting allows you to manually select the AGP driving value.

AGP Master 1 WS Write/Read It is recommended to keep the default setting for a stable system operation. 6. AGP 3.0 Calibration Cycle Available options: [Enabled], [Disabled]. 7. DBI Output for AGP Trans Please leave the default setting [Disabled] for a stable system operation.

Memory Hole Enabling this function will reserve the memory address space between 15MB and 16MB for ISA expansion cards. However, enabling this function will result in not allowing the system to have access to memory above 16MB. Please note that some expansion cards require this setting to be Enabled. The default setting is Disabled. If Auto Configuration is enabled, you must set the DRAM timing function to 60ns or 70ns, depending on the type of DRAM you install. System BIOS Cacheable Enabling this function 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. It is advised to leave this setting. Caching the system BIOS results in better performance than shadowing the system BIOS.
4. Primary/Secondary Master/Slave UDMA Ultra DMA implementation is possible only if your IDE device supports it and your operating environment contains a DMA driver. If both your hard drive and software support Ultra DMA, select [Auto] to enable BIOS support. 5. IDE HDD Block Mode Block mode is also called block transfer, multiple commands, or multiple sector read/write. If your IDE hard drive supports block mode, select Enabled to auto-detect the optimal number of block read/writes per sector.

7. USB Keyboard Support Select Enabled if your system has a USB keyboard installed on the system board. If your system has no USB keyboard, select Disabled in this field.
Power Management Option Power management allows the computer to save electricity when it is not in use by entering increasingly deep 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. 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.
Ac Loss Auto Restart Available options: [Auto], [On], [Off]. Please leave the default setting [Off] for a stable system operation. IRQ/Event Activity Detect

10. PowerOn by Ring/WOL

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. Run VGABIOS if S3 Resume Available options: [Auto], [Yes], [No].

When enabled, a 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.
Linear Spread Range Please leave the default setting [1] for a stable system operation. CPU Clock It is recommended to keep the default setting for a stable system operation. 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.

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 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. Auto Detect PCI/DIMM Clk Enabling this function will auto-detect PCI/DIMM clock. Spread Spectrum Available options: [Disabled], [Enabled].

3-8 Load Fail-Safe Defaults Load Fail-Safe Defaults loads the default BIOS values directly from the CMOS Setup Utility menu (Figure 3-1). 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 (Figure 3-1). 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.
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.
