Static Precautions

Static discharge can damage electronic components. To prevent that, it is important to handle it carefully. The following measures will suffice your equipment from static.

y Use a grounded wrist strap designed for static discharge. y Touch a grounded metal object before you remove the board from the

anti-static bag.

y Handle the board by its edges only; do not touch its components, peripheral

chips, memory modules, or gold contacts. Do not touch pins on chips or modules.

y Put the system board and peripherals back in anti-static bags when they are

not in use.

y For grounding purposes, be sure your computer chassis provides excellent

conductivity between its power supply, case, the mounting fasteners, and the system board.

3.1 CPU Installation

Please refer to the instruction manual of the CPU for how to install the CPU.

3.2 Memory Installation

Hard Disk Connector

The on-board Enhanced IDE controller can support up to 4 IDE hard drives or other ATAPI devices, such as CD-ROMs. This controller, as with all Enhanced IDE controllers, consists of both Primary (IDE 1) and Secondary (IDE 2) ports. Each port has an associated connector and cable, which can support up to 2 ATAPI devices each.

All IDE devices have jumpers, which allow the user to configure the device as either “Master” or “Slave”. A Master device is one that is ALONE on the IDE cable, whereas a Slave device is installed as a SECOND device on the same cable. Keep in mind that the Master device will appear before the Slave device in the CMOS Setup, as well as the Operating System

Mainboard IDE Port

software. *Refer to the device documentation for jumper settings.

The Secondary

Blue Connector

Gray Connector

Black Connector

IDE port can be used for up to 2 additional ATAPI devices. Normally it’s recommended that you connect your first hard drive to the Primary port, and the first CD-ROM to the Secondary.

Make sure to align the RED stripe on the ribbon cable with Pin-1 on the motherboard IDE connector. On most hard drives and CD-ROMs, the RED stripe should be oriented towards the power connector of the device.

When using Ultra ATA 66/100 IDE cable (as shown above), the black color connector on the cable is for Master drive, gray color is for Slave drive and blue color is for connecting to IDE port onboard.

Floppy Disk Connector (FLP1)

The on-board floppy controller supports 2 floppy disk drives. Make sure the RED stripe on the ribbon cable is oriented towards Pin-1. Notice the “twist” between the sets of connectors on the floppy cable. The floppy drive “A” position is at the END of the cable, whereas floppy drive “B” is hooked to one of the connectors on the other side of the twist.

4. BIOS Setup

The BIOS Setup (also called CMOS Setup) is where many hardware configurations are done and stored. This configuration information will remain in the BIOS until it is changed, or cleared. CMOS refers to the chip in which the BIOS information is stored, even when the power is turned off.

AwardBIOS CMOS setup utility allows you to change hardware settings in the BIOS. This chapter gives a detailed description of each setup item as to what function it controls and how one can modify its setting.

This motherboard also features a Flash BIOS. A Flash BIOS can be upgraded by software programs.

The AwardBIOS is activated once you boot the computer. The BIOS reads CMOS for system configuration information, and begins the process of checking out the system and configuring it through the power-on self test (POST).

When three preliminaries are finished, the BIOS seeks an OS on one of the data storage devices (hard drive, floppy disk, etc.) and launch it.

During POST, you can start the Setup program by pressing Del.

The AwardBIOS supports an override to CMOS settings, which will reset your system to its default configuration if your computer can no longer boot up after making changes.

We suggest you to only alter settings you have thorough knowledge of. Do not change settings without a good reason.

To enter the Award BIOS program's main menu:

y Turn on or reboot the system. y After the diagnostic checks, press the [Del] to enter the Award BIOS Setup

Utility.

To select items:

y Use the arrow keys to move between items and select fields. y From the Main Menu, press arrow keys to enter the selected submenu.

To modify selected items:

y Use the [Up]/[Down] keys to modify values within the selected fields. Some

fields let you enter values directly.

4.1 Main Menu

Once you enter the AwardBIOS CMOS Setup Utility, the Main Menu appears on the screen. Main Menu presents you the Setup functions included two exit choices. You could use the arrow keys to select among the items and then press Enter to the submenu.

* Description of selected item is shown in the column on the bottom of the screen.

4.2 Standard CMOS Features

The Standard CMOS Features allows you to choose the options in the setting item for basic system configuration.

* The Item Help column contains the description of selected item.

Date [mm:dd:yy]

The BIOS determines the day of the week from the other date information. It is for information only.

Time [hh:mm:ss]

The time format is <hour> <minute> <second>. The time is calculated based on the 24-hour military-time clock. For example, 1 p.m. is 13:00:00.

IDE Primary Master/ Primary Slave/Secondary Master/Secondary Slave

After pressing [Enter], a menu window appears as shown on below:

The BIOS supports up to four IDE drives. This section does not show information about other IDE devices, such as a CD-ROM and SCSI drives.

* The Item Help column contains the description of selected item.

IDE HDD Auto-Detection

The “IDE HDD Auto-Detection” utility is a very useful tool especially when you do not know the type of hard disk you are using. You can use this utility to detect the correct disk type installed in the system automatically. The BIOS will automatically detect the hard disk size and model during POST.

The AwardBIOS supports 3

HDD modes: NORMAL, LBA and LARGE modes.

The Generic access mode, neither BIOS nor IDE controller, will make transformations during accessing.

NOTE: There must be some software involved to support LBA or LARGE mode of

HDDs. All the software needed is located in the Award HDD Service Routine (INT 13h). It may fail to access a HDD with LBA (LARGE) mode selected if you are running under an Operating System, which replaces the whole INT 13h. UNIX operating system do not support either LBA or LARGE, and must utilize the Standard mode. UNIX can support drives larger than 528MB.

Under the AUTO Mode, the BIOS can automatically detect the specifications and optimal operating mode of almost all IDE drives. When you select type Auto for a hard drive, the BIOS detects its specifications during POST, every time the system boots.

IT IS RECOMMENDED THAT YOU SELECT THE TYPE AUTO FOR ALL DRIVES.

Drive A /Drive B [1.44M, 3.5 in.]

Select the correct specifications for the diskette drive(s) installed on your system.

Video [EGA/VGA]

Select the type of primary video subsystem on your system. The BIOS usually detects the correct video type automatically, and supports a secondary video subsystem that cannot be selected in Setup.

Halt On [All, But Keyboard]

During the power-on self test (POST), the system stops if the BIOS detects a hardware error. You can ask the BIOS to ignore certain errors and continue the process. There are the options:

All Errors: If the BIOS detects any non-fatal error, POST stops and

prompts you to take corrective action.

No Errors: POST does not stop for any error. All, But Keyboard: POST does not stop for keyboard error, but stops for all

other errors.

All, But Diskette: POST does not stop for diskette drive errors, but stops for all

other errors.

All, But Disk/Key: POST does not stop for a keyboard or disk error, but stops

for all other errors.

Memory

You can not change the value in the Memory fields which are information only. The setting item shows the total installed random access memory (RAM) and amounts allocated to base memory, extended memory, and other (high) memory.

RAM is the computer’s working memory where the computer stores programs and data currently being used, so they are accessible to CPU.

y Base Memory: Typically 640 KB is also called conventional memory. The

DOS operating system and conventional applications use

this area.

y Extended Memory: The memory over the 1MB boundary. y Total Memory: Total memory available from the system.

4.3 Advanced BIOS Features

* The Item Help column contains the description of selected item.

Virus Warning [Disabled]

The BIOS will halt on the system. Then the warning message appears as follows if there is virus.

!PBVA WARNING!

Paragon Boot Virus analyzer has

detected virus activity on hard disk

We recommend you to press: [Enter] Boot from clean disk

NOTE: When this item is enabled, the monitoring boot sector virus only happens

[C] Continue Boot

at the booting period. After you enter the system, this function is disabled automatically. So you can run any kind of program, such as many disk diagnostic programs, which attempt to access boot sectors or the partition table of hard disk drive when it is running.

CPU Internal/External Cache

Cache memory is additional memory that is much faster than conventional DRAM (system memory). When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even faster access by the CPU. Select Enabled to enable cache.

Quick Power On Self Test [Enabled]

Select Enabled to reduce the amount of time required to run the POST. A quick POST skips certain steps. We recommend that you normally disable quick POST. Better to find a problem during POST than lose data during your work.

First, Second, Third, Fourth Boot Device [HDD-0, Floppy, SCSI, Disabled]

Thiese setup fields determine which drive to be searched first, second or third for the disk operating system (i.e. DOS). You can select your priority bootup drives as Floppy drive A, IDE Hard Disk Drive C, D, E, F, or SCSI.

Swap Floppy Drive [Disabled]

This field is effective only in system with two floppy drives. This item allows you to determine whether to enable the swap floppy drive or not (i.e. physical floppy disk A assigned to logical drive B or physical drive B to logical drive A).

Boot Up Floppy Seek [Enabled]

During the “POST” process, BIOS will determine if the floppy disk drive installed is 40 or 80 tracks. 360K-type is 40 tracks while 760K, 1.2M and 1.44M are all 80 tracks. Because few modern PCs have 40-track floppy drives, we recommend that you set this field to Disabled to save time.

Boot Up NumLock Status [On]

This field allows you to determine the default state of the numeric keypad. “On”: keypad is number keys after boot up. “Off”: keypad is arrow keys after boot up.

Gate A20 Option [Fast]

Gate A20 refers to the way the system addresses memory above 1MB (extended memory). When set to Fast, the system chipset controls Gate A20. When set to Normal, a pin in the keyboard controller controls Gate A20. Setting to Fast improves system speed, particularly with OS/2 and Windows.

Typematic Rate Setting [Enabled]

Setting Enabled allows you to adjust both settings. You can use this feature to accelerate cursor movement with the arrow keys. When this item is set Disabled, keep holding down a key will let the system to use the default typematic rate delay of 250 msec, and typematic rate of 6 chars/sec to input repeatedly.

Typematic Rate (Chars/Sec) [6]

When “Typematic Rate Setting” is Enabled, its selections allow you to select the rate at which character repeats when you hold down a key.

Typematic Delay (Msec) [250]

When “Typematic Rate Setting” is Enabled, its selections allow you to select the delay before key strokes begin to repeat.

Security Option [Setup]

If you have set a password at USER PASSWORD option in main menu, select whether the password is required every time the System boots, or only when you enter Setup. The options include: System and Setup.

APIC Mode [Enabled]

The options are: Enabled and Disabled.

OS Select For DRAM > 64MB [Non-OS2]

Allow you to access memory that is over 64MB in OS/2. Choose OS2 when you are using OS2 and SDRAM size greater than 64 MB. Choose Non-OS2 for other operating systems. The options are: Non-OS2, OS2.

Small Logo (EPA) Show [Enabled]

The options are: Enabled and Disabled.

4.4 Advanced Chipset Features

* The Item Help column contains the description of selected item.

This section allows you to configure the system based on the specific features of the installed chipset. This chipset manages bus speeds and access to system memory resources, such as DRAM and the external cache. It also coordinates communications between the conventional ISA bus and the PCI bus. It must be stated that these items should never need to be altered.

The default settings have been chosen because they provide the best operating conditions for your system. The only time you might consider making any changes would be if you discovered that data was being lost while using your system.

System BIOS Cacheable [Enabled]

Selecting 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 RAM Cacheable [Disabled]

The options are: Disabled and Enabled.

AGP Aperture Size [64]

This setting item allows you to select the size of the Accelerated Graphics Port (AGP) aperture. The aperture is a portion of the PCI memory address range dedicated for graphics memory address space.

The options are: 4, 8, 16, 32, 64, 128, and 256.

4.7 PnP/PCI Configurations

* The Item Help column contains the description of selected item.

The PCI Personal Component Interconnect Bus was developed primarily to address two important issues: (a) How to allow peripheral devices to take the fullest advantage of the power of CPU technology, and (b) Provide a simpler installation process for peripheral devices, such as Network cards, EIDE or SCSI controllers.

PCI accomplishes these goals with its 32-bit Data path Local Bus design, and support for Plug & Play. Unlike older expansion bus architectures, PCI provides peripherals with a direct connection to the CPU and memory. The PCI bus runs at 33Mhz and has a maximum transfer capability of 132MBps. With Plug & Play, the system BIOS automatically determines hardware resources for new peripherals, simplifying installation of multiple interface cards.

This Setup Menu provides configuration options for the PCI Bus and its assigned resources.

Reset Configuration Data [Disabled]

y Disabled: Normal Setting

y Enabled: Select Enabled to reset Extended System Configuration Data

(ESCD) when you exit Setup if you have installed a new add-on and the system reconfiguration has caused such a serious conflict that the operating system cannot boot.

Resource Controlled By [Auto (ESCD)]

y Manual: The field defines that the PNP Card's resource is controlled by

manual. You can setup whether IRQ-X or DMA-X is assigned to PCI/ISA PnP or Legacy ISA Cards.

y Auto: If your ISA card and PCI card are all PNP cards. Set this field to

"Auto". The BIOS will assign the interrupt resource automatically.

IRQ Resources [Press Enter]

Pressing Enter will take you to the IRQ Resources setup screen that allows you to assign each IRQ to a device. When the resources are controlled manually, pressing Enter will take you to the IRQ Resources setup screen that allows you to assign each system interrupt as a PCI device or reserve the IRQ, depending on the type of device using the interrupt:

PCI/VGA Palette Snoop [Disabled]

Selecting Enabled 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.

4.8 PC Health Status

* The Item Help column contains the description of selected item.

This section helps you to get more information about your system including CPU temperature, FAN speed and voltages. It is recommended that you contact with your motherboard supplier to get proper value about your setting of the CPU temperature.

NOTE: When a Cyrix CPU is installed, the CPU Temperature and the System

Temperature will not be displayed.

4.9 X-BIOS

* The Item Help column contains the description of selected item.

Clock Spread Spectrum [Disabled]

When the system clock generator pulses, the extreme values of the pulse generate excess EMI. Enabling pulse spectrum spread modulation changes the extreme values from spikes to flat curves, thus reducing EMI. This benefit may in some cases be outweighed by problems with timing-critical devices, such as a clock-sensitive SCSI device. You can reduce EMI by setting this item to turn on the clock signal with spread spectrum support.

The options include: 0.5%, 1%, 2%, and Disabled.

The BASIC Defaults have been set to provide the minimum requirements for your system to operate. Its performance is lower than the “Load Best Defaults”. We suggest you use “Load Best Default”. If your system card has compatibility issues, use the “Load Basic Defaults”.

4.11 Load Best Defaults

The “Load Best Defaults” function loads the system manufacture default data. This is the default setting from Leadtek. This function will be necessary when the system CMOS data is corrupted or you forget your settings.

4.12 Set Supervisor/User Password

Passwords can be set to provide protection for the BIOS configuration options, or to restrict access to the computer itself.

When enabled, User Password will require all users to enter a password in order to use the system, and/or enter the BIOS setup (but can’t change its contents). A Supervisor Password is used to protect the stored CMOS options from being changed by unauthorized users.

Keep in mind that when set, a password is required only when booting the system. It will not provide protection to a system that is already booted.

The password check option is set in BIOS FEATURES SETUP by choosing either System (the password prompt appears every time the system is powered on) or Setup (the password prompt appears only when the user enters the BIOS Setup). The password is stored in CMOS RAM, and can be cleared by removing the battery for a while and then re-installing it back.

To set a password:

y You must first set the Supervisor password by choosing Supervisor Password

and pressing [ENTER]. Setup prompts for a password.

y Enter a 1~8 character password using letters, numbers, or a combination of

both. The specific characters are not shown as you enter them. Press [ENTER].

y A confirmation box appears asking you to re-enter the password. Enter the

password again. Press [ENTER]. Follow the same procedure to set the User Password.

To change a password:

Select the appropriate password option (Supervisor or User) from the main menu

and press [ENTER]. Enter the current password and press [Enter]. The screen does not display the characters entered. Enter in the new password, then the confirmation. You cannot change the current password unless you know it.

To erase a password:

y If you know the current password, but want to disable password checking,

follow the procedure for changing the password. When the Setup prompts for the new password, simply press [ENTER]. You will see a message indicating that the password is disabled.

y If you do not know the current password, you can clear the CMOS data by

removing the battery for a while and then re-installing it back (this will clear all the user-defined BIOS).

4.13 Save & Exit Setup

The “SAVE & EXIT SETUP” option will bring you back to boot up procedure with all the changes you just recorded in the CMOS RAM.

4.14 Exit Without Saving

The “EXIT WITHOUT SAVING” option will bring you back to normal boot up procedure without saving any data into CMOS RAM, and will not destroy all the old data in CMOS.
