3.1. Unpacking

The A7F129 mainboard package contains the following items:

q One mainboard q One IDE 40-pin ribbon cable q One floppy 34-pin ribbon cable q Driver and utility CD q User's manual

After removing the mainboard from its anti-static bag, place it on a grounded or anti-static surface (component side up). Inspect the

mainboard and contact your vendor immediately if it is damaged.

Mainboard User’s Manual

3.2. Installation

The A7F129 is designed to fit into a standard ATX form factor chassis. The pattern of the mounting holes and the position of the back panel connectors meet the ATX system board specification. The chassis comes with various mounting fasteners, which are made of metal or plastic. It is highly recommended to use as many metal fa steners as possible to mount the mainboard in the chassis for better grounding.

To install the mainboard you need to install the CPU and DIMM memory modules, attach the connectors, and set the correct CPU

speed in the CMOS setup.

14 Installation

Hardware Installation

3.3. Safety Measures

Computer components and electronic circuit boards can be damaged by discharges of static electricity. Working on computers that are still connected to a power supply can be extremely dangerous. Follow the simple guidelines below to avoid damaging your computer:

• Always disconnect the mainboard from the ATX power

supply, and disconnect the computer from the power outlet whenever you are working inside the computer case.

• If possible, wear a grounded wrist strap when you are in-

stalling the mainboard or working inside the computer case. Alternatively, discharge any static electricity by touching the bare metal chassis of the computer case, or the bare metal body of any other grounded appliance.

• Hold electronic circuit boards by the edges only. Do not

touch the components on the board unless it is necessary to do so. Do not flex or stress the circuit board.

• Leave each component inside the static-proof packaging

that it ships with until you are ready to use the component for the installation.

32 Installing the CPU

4. KT Mainboard BIOS

After the hardware configuration of the mainboard is finished, and the system hardware has been assembled, the system may be powered up. At this point, CMOS setup should be run to ensure that

system information is correct. The mainboard employs the latest Award BIOS CMOS chip with

support for Windows Plug and Play. This CMOS chip contains the ROM Setup instructions for configuring the mainboard’s BIOS. The BIOS (Basic Input and Output System) Setup program is a menu driven utility that enables you to make changes to the system configuration and tailor your system to suit your individual work needs. It is a ROM-based configuration utility that displays the system’s configuration status and provides you with a tool to set system parameters. These parameters are stored in non-volatile battery-backedup CMOS RAM that saves this information even when the power is turned off. When the system is turned back on, the system is configured with the values found in CMOS.

Using easy-to-use pull down menus, you can configure such items as:

• Hard drives, diskette drives, and peripherals

• Video display type and display options

• Password protection from unauthorized use

• Power management features

The settings made in the Setup program intimately affect how the computer performs. It is important, therefore, first to try to understand all the Setup’s options, and second, to make settings appropriate for the way you use the computer. This chapter provides

clear explanations for all Setup options.

Mainboard User’s Manual

This program should be executed under the following conditions:

• When changing the system configuration

• When a configuration error is detected by the system and

you ar e prompted to make changes to the Setup program

• When resetting the system clock

• When setting the CPU clock speed so that it automatically

runs either fast or slow

• When redefining the communication ports to prevent any

conflicts

• When making changes to the Power Management configu-

ration

• When changing the password or making other changes to

the security setup

Normally, CMOS setup is needed when the system hardware is not consistent with the information contained in the CMOS RAM, whenever the CMOS RAM has lost power, or the system features need to be changed.

4.1. Entering Setup

When the system is powered on, the BIOS will enter the Power-On Self Test (POST) routines. These routines perform various diagnostic checks; if an error is encountered, the error will be reported in one of two different ways:

1. If the error occurs before the display device is initialized, a

series of beeps will be transmitted.

2. If the error occurs after the display device is initialized, the

screen will display the error message.

34 Entering Setup

54 PnP/PCI Configurations

KT Mainboard BIOS

Reset Configuration Data: The system BIOS supports the Plug and Play feature so the resources assigned to each peripheral have to be recorded to prevent them from conflicting. The location to store the assigned resources is called ESCD (Extended System Configuration Data) which is located in the system flash EEPROM. If this option is set to Disabled, the ESCD will update automatically when the new configuration varies from the last one. If set to Enable, the ESCD will be cleared and updated and then this option will automatically be

set to Disabled. Resources Controlled By: You should change this item to

Auto(ESCD). Under this setting, the system dynamically allocates resources to plug and play devices, as they are required.

If you cannot get a legacy ISA (Industry Standard Architecture) expansion card to work properly, you might be able to solve the problem by leaving this item at the default setting Manual, and then

opening up the IRQ Resources and DMA Resources sub-menus. In the IRQ Resources sub-menu, if you change any of the IRQ assig-

nations to Legacy ISA, then that Interrupt Request Line is reserved for a legacy ISA expansion card. Press Esc to close the IRQ Re- sources sub-menu.

Resources Controlled By: The default setting is Manual which allows you to control IRQs and DMAs individually. The other option is Auto (ESCD) which will detect the system resources and auto-

matically assign the relative IRQs and DMAs for each peripheral. IRQ Resources: This field becomes available if the Resources Co n-

trolled By field is set to Manual. Pressing <Enter> displays a list of IRQs and their current assignments. If there is a legacy ISA device which uses an IRQ, set the corresponding IRQ to Le gacy ISA, oth-

erwise, you should set the field to PCI/ISA PnP. DMA Resources: This field becomes available if the Resources

Controlled By field is set to Manual. Pressing <Enter> displays a list of DMAs and their current assignments. If there is a legacy ISA device which uses an DMA, set the corresponding IRQ to Legacy ISA;

otherwise, you should set the field to PCI/ISA PnP.

If you only want to install setup defaults for a specific option, select and display that option, and then press the <F7> key.

4.11. Set Supervisor/User Password

The Supervisor/User Password utility sets the password. The mainboard is shipped with the password disabled. If you want to change the password, you must first enter the current password, then at the prompt enter your new password. The password is case sensitive. You can use up to eight alphanumeric characters. Press <Enter> after entering the password. At the next prompt, confirm the new pass-

word by retyping it and pressing <Enter> again. To disable the password, press <Enter> instead of entering a new

password when the Enter Password dialog box appears. A message appears confirming that the password has been disabled.

If you have set supervisor and user passwords, only the supervisor password allows you to enter the BIOS Setup Program.

Note: If you forget your password, the only way to solve this problem is to discharge the CMOS memory by turning power off and placing a shunt on jumper JP12 to short pin 2 and pin 3 for five seconds, then putting the shunt back to pin 1 and pin 2 of JP12.

5. KM/KL Mainboard BIOS

After the hardware configuration of the mainboard is finished, and the system hardware has been assembled, the system may be powered up. At this point, CMOS setup should be run to ensure that

system information is correct. The mainboard employs the latest Award BIOS CMOS chip with

support for Windows Plug and Play. This CMOS chip contains the ROM Setup instructions for configuring the mainboard’s BIOS. The BIOS (Basic Input and Output System) Setup program is a menu driven utility that enables you to make changes to the system configuration and tailor your system to suit your individual work needs. It is a ROM-based configuration utility that displays the system’s configuration status and provides you with a tool to set system parameters. These parameters are stored in n on-volatile battery-backedup CMOS RAM that saves this information even when the power is turned off. When the system is turned back on, the system is configured with the values found in CMOS.

Using easy-to-use pull down menus, you can configure such item s as:

• Hard drives, diskette drives, and peripherals

• Video display type and display options

• Password protection from unauthorized use

• Power management features

The settings made in the Setup program intimately affect how the computer performs. It is important, therefore, first to try to understand all the Setup’s options, and second, to make settings appropriate for the way you use the computer. This chapter provides

clear explanations for all Setup options.

Exit Without Saving 61

Mainboard User’s Manual

This program should be executed under the follow ing conditions:

• When changing the system configuration

• When a configuration error is detected by the system and

you are prompted to make changes to the Setup program

• When resetting the system clock

• When setting the CPU clock speed so that it automatically

runs either fast or slow

• When redefining the communication ports to prevent any

conflicts

• When making changes to the Power Management configu-

ration

• When changing the password or making other changes to

the security setup

Normally, CMOS setup is needed when the system hardware is not consistent with the information contained in the CMOS RAM, whenever the CMOS RAM has lost power, or the system features need to be changed.

5.1. Entering Setup

When the system is powered on, the BIOS will enter the Power-On Self Test (POST) routines. These routines perform various diagnostic checks; if an error is encountered, the error will be reported in one of two different ways:

1. If the error occurs before the display device is initialized, a

series of beeps will be transmitted.

2. If the error occurs after the display device is initialized, the

screen will display the error message.
