The BIOS-Related JumperThe BIOS-Related Jumper

The BIOS-Related Jumper

Jumper JP1: Clear CMOS Memory

JP1 is a jumper switch, but it does not set a hardware configuration setting. The BIOS CMOS Setup Utility creates a system configuration record that is stored in CMOS memory in the real-time clock chip. If the configuration record data becomes corrupted or is destroyed, or if the CMOS Setup Utility settings are changed to an unusable configuration, the motherboard may not run properly or at all. JP1 provides a means to delete the configuration data stored in CMOS memory and reset the configuration to the CMOS Setup Utility’s Optimized Defaults.

Follow this procedure to clear CMOS memory. If necessary , refer to the motherboard diagram and k e y in Chapter 2 for the jumper location.

1. Turn off and unplug the system. R emove the s ystem housing cover (see documentation if necessary).

2. Set JP1 to the Clear CMOS position by placing the jumper cap over pins 2 and 3 for one minute.

3. Return the jumper cap to the Normal position.

4. Replace the system housing cover, plug in the system and turn it on.

5. Run the CMOS Setup utility and load the Optimized Defaults. You can then enter any custom settings you require.

6. Save the settings as you e xit the program and r estart the computer.

The system should now operate normally.

Firmware Configuration: The CMOS Setup Utility

The BIOS CMOS Setup Utility a configuration record of system settings. This record is based on the “Optimized Defaults that are stored with the utility in Flash memory and can be reloaded at any time.

Many of these settings are either recommended or required for the motherboard to operate properly. Other settings are customizable and can be changed to suit your specific system configuration and oper ation requirements.

A number of the variable settings, such as CPU and IDE device settings are set to be automatically detected in the default configuration. While these settings can also be established manually, automatic detection is more convenient, safe and reliable. We strongly recommend that you leave all auto-detection settings undisturbed unless you have a specific reason not to and you are certain of what you are doing. Incorrect configur ation of the CMOS Setup Utility can result in unreliable operation or a failure of the motherboard to work at all.

Using the CMOS Setup Utility

Please refer to the “Configuring the CMOS Setup Utility” section in Chapter 5 for information on using the utility and some settings you might want to customize . The utility does not run under an Operating System. You must load it during the Power On Self Test (POST) while the computer is starting up by press the Delete key or the Del key on the system keyboard’s numeric keypad.

Reconfiguring the MotherboardReconfiguring the Motherboard

Reconfiguring the Motherboard

You can change the default configuration (as shipped) of this motherboard as needed. However, since this motherboard has only a few hard configuration options and the CMOS Setup Utility configuration is mostly either required, recommended or automatic , there will probably be little reason to do so.

Hardware Reconfigur ation

W e recommend lea ving the jumper settings at the default settings unless you need to perform the Clear CMOS procedure. It is much more convenient to control the BIOS Flash Protection feature using the CMOS Setup Utility.

The default setting is correct for any DDR memory you can install on this board. The alternate settings in the CMOS Setup Utility are only used for overclocking.

Firmwar e Reconfiguration

You can initially specify or customize the CMOS Setup Utility settings when you first configure the system (as covered in Chapter 5) to meet your requirements. Other than doing this, there should be no need to reconfigure the CMOS Setup Utility unless the system configuration changes or the configuration record stored in CMOS memory becomes corrupted and unusable, which is not common. If you need to completely recreate the system configuration record, follow the Clear CMOS procedure described in this chapter.

Installing The Processor

Installing a processor in the Socket 462 is a simple procedure. It is v ery important, how ev er, to carefully handle the processor by the edges and always fully observe precautions against electrostatic discharge . We assume here that you are installing a “boxed” processor, that is, one packaged by AMD and sold retail. If you are installing a non-boxed processor, the procedure is the same, but the accessory items may have a different appearance.

Please follow the installation procedure as illustrated on the next two pages. The illustrations are generic and do not specifically represent this motherboard.

The processor installation procedure is as follows:

Raise the socket lever to the vertical position

Step 1:Step 1:

Step 1: Raise the retaining lever

Two corners hav e pins missing on the socket and the processor

Step 2:Step 2:

Step 2: Align the CPU so that the two corners with missing pins match the corresponding receptacles in the socket.

Note:Note:

Note: All supported CPUs install the same way .

Important:Important:

Important: If you install a CPU that has a 266MHz FSB speed, (Athlon and Athlon XP) you must config in the BIOS.

2. Align the processor to the socket by matching the beveled Pin 1 corner of the CPU to the Pin 1 corner on the socket, which is located at the corner where the locking arm attaches to the socket.

1. Raise the locking lever of the processor locking mechanism to a perpendicular position.

Installing Memory Modules

Installing DIMM modules is simple. The modules insert in the sockets and are held in place by the socket retaining arms. The edge connectors on the modules are of different widths and there are key notches in each module. These ensure that y ou can not insert a module incorrectly.

Before you install any modules, you should choose a configuration. You should then prepare the required number and type of DDR modules.

To install either type of module follow this procedure:

1. Align the module to the socket so that the edge

connectors on the module match the socket sections.

2. Hold the module perpendicular to the motherboard

and press the edge connector into the socket.

3. Press the module fully into the socket so that the

socket retaining arms swing up and engage the retention notches at each end of the module.

Follo wing the configuration y ou ha ve chosen, repeat this procedure if necessary so that all modules are installed. Once the modules are installed, system memory installation is complete.

Connecting Internal Devices

To assemble a complete system capable of completing the installation of this motherboard you will need to install and connect the following internal devices:

• Hard Disk Drive

• CD-ROM or other optical drive

• Floppy disk drive The floppy disk drive is not strictly necessary, but is a

standard system component and is needed if y ou will create driver floppy disks from the Power Installer 2.

We assume here, in the absence of an alternative drive controller that any hard disk or optical driv es will be IDE devices connected to the motherboard’s IDE channels.

Connecting IDE Devices

This motherboard supports two IDE channels, Primary and Secondary . It has two IDE device connectors onboar d which support IDE devices running in any data transfer mode up to ATA-100. Each IDE connector supports two drives, a Master and a Slave. The drives connect to the motherboard with an IDE ribbon cable. IDE cables have three connectors on them, one that plugs into a drive connector on the board and the other two that connect to IDE devices. The connector at the end of the cable is for the Master drive. The connector in the middle of the cable is for the Slave drive.

There are different types of IDE ribbon cable, supporting transfer modes up through ATA -33, ATA-66 or AT A-100 or ATA-133. You must use a cable that supports the transfer mode of the fastest device connected to it. F or example , if both an ATA-66 mode and an ATA-100 mode device are connected to the same cable, the cable must support AT A 100 mode to achieve maximum performance.

To install an IDE drive, connect the drive to one of the drive connectors on a suitable ribbon cable . Plug the board end of the cable into one of the IDE connectors on the motherboard.

IDE Drive Positioning

Normally the system’s primary har d disk drive should be in the Primary Master position. If you will use only the supplied ribbon cable, connect a CD-ROM drive to the Primary Slave position.

If you obtain an additional IDE ribbon cable, you can install a second hard disk drive in the Primary Slav e position and install the CD-ROM as the Secondary Master. This is a good idea if the CD-ROM drive uses a slower data transfer mode than the hard disk drive.

Follo w any instructions that come with the drives to configure and install them. IDE devices generally can be set to one of three operation modes:

• Master

• Slave

• Cable Select Many drives come set to the Master setting. If you will

use the drive in a Slav e position, y ou must reconfigur e it as either Slave or use the Cable Select setting to allow the drives position on the cable to define the mode.

Connecting a Floppy Disk Drive

This motherboard has one Floppy Drive connector for connecting one or two floppy disk drives . Most computer systems use one 3.5-inch 1.44MB floppy disk drive. The drive connector is for a standard floppy driv e ribbon cable.

T o install a flopp y disk drive , connect the drive to the end of the cable, which is the Drive A: position. Plug the other end of the cable into the floppy disk drive connector on the motherboard.

Cable Select:Cable Select:

Cable Select: Not all drives work pr operly with Cable Select mode. If you try to use this mode and the drive does not operate properly, set the drive to either Master or Slave mode, as appropriate f or its position on the cable.

Pow er Button

Function: Turns the system On and Off. Use: This button is configured by the CMOS Setup Utility

by the “Soft-Off Mode by PWR-BTTN” line in the Power Management section. Depending on the setting, the power button will function in one of two modes, instant on/off or instant on/4-second delay off. In the delay mode , when you push the power button for less than 4 seconds when the system is on, the system goes into the Suspend power conserv ation mode. In this mode, y ou have to push the button for more than 4 seconds to turn the system power off.

Reset Switch

Function: Restarts the system to cold boot. Use: Press the button to restart the s ystem. This forces a

restart under all conditions. Don’t use the R eset button if you can shut the system do wn from within the Operating System.

Note On Reset & Rebooting: You should always restart or shut down the system by

using the OS command for this. This procedure allows the OS to shut down properly, minimizing the possibility of hard disk drive problems or data loss. If the system crashes or “hangs”, you may have to restart the system at the hardware level. There are two hardware reboot options, a keyboard command and the Reset button.

You can effect a “warm” reboot with a key command if the OS supports it. For e x ample , all v ersions of Micr osoft Windows support restarting the computer with the CtrlAlt-Del (Delete) command. You can try this command first if it is supported. Otherwise, you will need to use the Reset button.

Suspend Button

Function: Toggles system in and out of Suspend mode. Use: Press the button to cause the system to enter or

resume from Suspend mode. Note: The front panel feature connector supports a sys-

tem Suspend button (the ACPI connector) but not all s ystem housings have this button. The same function can be performed at the Operating System le vel if the OS supports the feature.

There is a pin header connector for an Infrared communications port module on the motherboard. An IR port enable wireless communication between the s ystem and another device with IR capability. Common examples of such devices are a PDA or notebook computer. Installing an IR port module requires disabling the COM2 serial port on the rear I/O panel and reconfiguring it for IR use in the CMOS Setup Utility.

Installing an IR port module requires an expansion slot opening unless the system housing has a built-in IR port with a cable to connect to the motherboard.

Follo w the instructions that come that come with the port module you want to install. The basic installation pr ocedure is as follows if the module installs in an expansion slot opening:

1. Turn off and unplug the system if necessary.

2. Remove the system housing cover.

3. Locate the JP5 IR pin header connector on the motherboard.

4. Remove the e xpansion slot cover in the sy stem housing that corresponds to an open PCI slot. There may be a slot cover retaining screw to remove and put aside for later use.

5. Insert the port module in the open expansion slot cover and align the module’s mounting br acket with the screw hole for the retaining screw If there is one). Insert the screw and tighten it to secure the port module in place.

6. Plug the module’s connector cable on to the IR connector on the motherboard.

7. Replace the system housing cover.

8. Plug in and turn on the computer.

9. Run the CMOS Setup Utility and pen the Integr ated Peripherals section. Set the “UART Mode Select” to the required mode, IrDA or ASKIR, and configure the port settings below it if necessary. Save the settings and reboot.

ormance Optimizationormance Optimization

ormance Optimization

This section covers things you can do to increase the performance of a system based on this motherboard. The topics covered include system memory, disk subsystems and processor upgrades or adjustments.

System Memory

Adding sy stem memory will increase system performance and capability under any of the supported Operating Sy stem. This motherboard supports a total of 3GB of unbuffered DDR DRAM system memory. If you have not installed the maximum, you can consider increasing the amount of installed system memory. Additional system memory speeds up system operation and in some cases produces additional stability in the Operating System.

Disk Subsystems

The main IDE controller on this motherboard supports IDE drives using data transfer modes up through ATA-

133. If you use IDE drives as the primary disk subsystem,

selecting drives that support ATA-133 and have a high rotation speed will maximize performance.

Processor Upgrades & Adjustments

Processor speed has a significant effect on over all system performance. To increase system performance, you can consider using or upgrading to a faster processor.

The AMD processors used by this motherboard come in a variety of clock speeds. To maximize performance, select a processor with the fastest clock speed the system budget or specification allows.

The CMOS Setup Utility’s Frequenc y/Voltage Setting section will automatically detect and configure whatever pr ocessors are installed. Manual configuration is also available, but setting the processor to operating parameters outside those specified by AMD can damage the CPU and void the warranty.

A hardware problem may occur either after you install additional hardwar e or because some e xisting har dw ar e has failed or has a disconnected or loose connection. This section has some pointers on things you can check before seeking assistance.

General Hardw are Troubleshooting

If the motherboard does not operate properly when you first try to use it in the system, it is likely that it is either configured incorrectly, there are problems with external connections. It os also possible the board or some other system component is defective. Always check the most obvious possibilities first.

First check the external components:

• Make sure the system, the monitor and any other external peripherals are plugged in and turned on. Confirm that the system and the power LEDs on any external peripherals are on.

• Check that the monitor, keyboard and mouse are properly connected.

Next check the CMOS Setup Utility:

• Run the CMOS Setup Utility and load the Optimized Defaults. Reset any other custom settings. Remember to “Save & Exit Setup” to restart the computer.

If there is still a problem, check the internal components. Turn off and unplug the system before you remove the system housing cover.

• Press all installed DIMMs into the module sockets

to make sure they’re fully inserted.

• Make sure you used the correct cables to connect

the internal peripherals and that the peripherals are properly connected to the motherboard. Check the Master/Slave positions on all IDE cables. If you installed a device that uses ATA- 100 mode, make sure it is connected to the motherboard with an ATA-100 cable to ensure maximum performance.

• Check that all expansion cards ar e correctly installed

and fully inserted in the expansion slots. Pay particular attention to the AGP display card if one is installed.

• Make sure the processor and its fan/heatsink cool-

ing assembly are properly installed.

• Check all the hardwar e settings on the motherboard

and make sure they are correct.

When you’re done, r eassemble the s ystem and try again. If the problem persists after you have checked all of the above, there may be a hardware conflict or bug. See the next section for additional information.

Hardwar e Configuration Problems

It is possible for system hardw are components to conflict with each other . While all the components and subsystems on the motherboard are designed and tested to work together, expansion cards and peripheral devices can be a problem.

Assuming you have gone through the general troubleshooting procedures and the sy stem still will not start, if you have just added ne w hardw are to y our sy stem, there may be a hardware conflict or bug or a problem with a device driver. Try removing the new hardw are and see if the system will start. If it does, consult with the device manufacturer for information on solving the problem. In some cases, a firmware or driver upgrade may resolve the problem.

Plug and Play Problems

This motherboard supports the automatic recognition and configuration of expansion cards that support the Plug and Play (PnP) specification. Most currently available expansion cards support PnP. PnP simplifies card installation by allowing the system to handle system resource allocation. If you install an expansion card that is not PnP compliant, you may still need to configure the card manually. Consult the card’s documentation for instructions or other information.

Replacing the System Configuration Record

As noted previously, the CMOS Setup Utility creates a system configuration record and stores it in CMOS memory on the motherboard. This record must be correct and uncorrupted for the system to operate properly.

It is possible for the system configuration record can become corrupted or lost. If this occurs, the sy stem will not operate properly or at all. This is not a serious problem. You can restore a working configur ation using the CMOS Setup Utility to create a new configur ation record by loading the Optimized Defaults and reentering any other settings you had made.

Loading Optimized Defaults

The CMOS Setup Utility does not require an operating system to run. You run the utility by typing the Del or Delete key while the system is starting up to brings up the utility’s main screen.

There are two sets of defaults listed, Optimized and FailSafe. The F ail-Safe Defaults ar e a minimum configuration set for use by technicians when troubleshooting system problems. The Optimized Defaults are what the system normally operates on. If a corrupted system configuration record caused the problem you experienced, once you load the Optimized Defaults and reboot, the system should function normally. The instructions on the next page illustrate this procedure.
