Memory The base memory size, extended memory size and the other memory

size cannot be altered; your computer automatically detects and displays them.

Base Memory The POST will determine the amount of base (or

conventional) memory installed in the system. The value of the base memory is typically 512K for systems with 512K memory installed on the motherboard or 640K for systems with 640K or more memory installed on the motherboard.

Extended Memory The BIOS determines how much extended

memory is present during the POST. This is the amount of memory located above 1MB in the CPU’s memory address map.

Other Memory This refers to the memory located in the 640K to

1024K address space. This is the memory that can be used for different applications. DOS uses this area to load device drivers in an effort to keep as much base memory free for application programs. The BIOS is the most frequent user of this RAM area since this is where it shadows the ROM.

Current CPU Temperature and Current CPU Fan Speed These fields show the current temperature of the processor and the

current fan speed of the processor’s fan in RPM (Revolutions Per Minute).

CPU Temperature Limit This field allows you to manually set a limit to the processor’s

temperature. If the temperature of the processor is over the temperature set in this field (70oC/158oF recommended), an alarm will sound warning you of system overheat. The sound of the alarm is continuous low to high beeps. Some of the most common causes leading to high temperature are:

- The fan is not functioning normally or has stopped. Turn off your system and replace the fan.

- The space clearance of the processor, fan and heat sink is inadequate to maintain proper airflow and heat dissipation.

- The chassis or cabinet has poor ventilation.

CPU Fan Speed Limit This field allows you to manually set a limit to the speed of the

processor’s fan. If the processor’s fan speed is under the speed set in this field, an alarm will sound informing you to attend to any issue that may damage your system. The sound of the alarm resembles that of the siren of an ambulance.

Chipset Voltage, +3.3V, +5V and +12V Voltages Set these fields to “Monitor” if you want the system board to detect

the chipset’s voltage and output voltage of the power supply. If the output voltage of the power supply is over or under +3.3V/+5V/ +12V (±10%), an alarm will sound warning you of voltage issue. The sound of the alarm is continuous low to high beeps but shorter than the temperature alarm. Some of the most common causes leading to unstable output voltage of a power supply are:

- The power supply is not functioning normally. Turn off your system and replace the power supply.

- The AC input from the power outlet to your system is unstable. Please consult your MIS department or an electrician.

System Memory

The system board supports two kinds of memory modules: DIMM and SIMM. DIMM, which sometimes uses SDRAM, performs better than SIMM, which uses DRAM. When you are purchasing DIMMs, please specify you want the Intel compatible type. (There are DIMMs made for other types of computers that are not compatible.)

Note:

DIM and SIM modules cannot exist on the system board at the same time. Use either SIMM or DIMM only.

DIMM

The two 168-pin DIMM (Dual Inline Memory Module) sockets use x64 EDO, FPM and SDRAM. The system board can support 8MB to 256MB memory. The table below summarizes the DIMM sockets and modules needed for the corresponding memory sizes.

Processor Upgrade Information

A processor’s internal clock speed is the actual internal operating clock of the processor. Its frequency ratio differs from one processor to another. An Intel processor will multiply the external bus clock by the frequency ratio to become the internal clock speed. Internal clock speed is the commonly known speed of Intel processors in the market and is the actual operating clock of the processor (external bus clock x frequency ratio = internal clock speed). Cyrix and AMD processors use the PR-rating system which is the overall processor performance rating.

The voltage of the processors are divided into Single voltage and Dual voltage processors. Single voltage processors include Intel Pentium, Cyrix 6x86 and AMD K5 processors. Dual voltage processors include Intel Pentium processors with MMX technology, Cyrix 6x86L and 6x86MX, and AMD K6 processors. Make sure all jumpers are set correctly before applying power or you may damage the processor or system board. Use a needle-nosed plier to move the jumpers if necessary.

Installing Upgrade Processors

The system board is equipped with a 321-pin Zero Insertion Force (ZIF) socket at location U5 of the system board. Refer to Appendix C for the location of the ZIF socket. This socket is designed for easy removal of an old processor and easy insertion of an upgrade processor. The ZIF socket allows you to carefully place the new processor into its position. If you need to apply excessive force to insert the processor, you are not installing the processor correctly.

Warning:

Open the socket only if you are actually installing a processor. The warranty on the original processor will be voided if the S/N seal is broken. Before proceeding with the upgrade, take note of the following. The microprocessor and heatsink may be hot if the system has been running. To avoid the possibility of a burn, power the system off and let the processor and heatsink cool for 20 minutes.

The 321-pin ZIF socket consists of five rows of pin holes on each side. To prevent improper processor installation, the ZIF socket has a Plug/Keying mechanism. Several holes in the socket are plugged so that the processor will go in only one way. If you cannot easily insert the processor, verify that pin 1 of the processor is aligned with pin 1 of the socket. Also verify that all the pins are straight, and not bent nor broken.

Zero Insertion Force (ZIF) Socket

Page 48

586ITXD System Board User’s Manual

To install an upgrade processor, do the following:

1. Make sure the handle on the side of the ZIF socket is up. To raise the handle, push it down, slightly pull it out to the side, then raise it as far as it will go. It may be necessary to initially apply a small amount of sideways force to free the handle from its retaining “tab”. Once clear of the “tab”, the handle will open relatively easily. The top plate will slide back. Do not use screwdrivers or other tools to open the socket, or you may damage the system or socket.

Handle

Lifting the Handle

2. Once the lever is completely up, remove the old processor carefully by lifting it straight out of the socket. You are now ready to insert the new processor.

Upgrade Guide

3. Position the processor above the ZIF socket. Make sure pin 1 of the processor is aligned with pin 1 of the socket. Lower the processor until the pins are inserted properly in their corresponding holes. Remember that very little force is needed to install the processor. If the processor is not easily inserted, verify whether or not pin 1 of the processor is aligned with pin 1 of the socket. Applying too much pressure can damage the processor or the socket.

Installing A Fan/Heatsink

Position the fan/heatsink on the processor such that the air from the side of the fan/heatsink will flow across the heat regulators on the system board. See the figure below.

Clearance Requirements

Your processor comes with a heatsink mounted on top. To maintain proper airflow once the upgrade is installed on the system board, the processor and heatsink require certain space clearances. The clearance above the processor’s fan/heatsink must be at least 0.4 inches. The clearance on at least 3 of 4 sides of the processor and heatsink must be at least 0.2 inches. All cables (for floppy drive, hard drive, CD-ROM, etc.) must be routed clear of the processor and its airspace.

Fan Exhaust

The processor must be kept cool by using a fan with heatsink. The temperature of the air entering the fan/heatsink cannot exceed 45oC (113oF). The ambient or room temperature must be below 37oC (99oF).

Desktop Management Interface

Page 54

Desktop Management Interface

Desktop Management Interface (DMI)

The system board comes with a DMI built into the BIOS. DMI, along with the appropriately networked software, is designed to make inventory, maintenance and troubleshooting of computer systems easier. With DMI, a network administrator or MIS engineer can remotely access some information about a particular computer system without physically going to it. Quite often a service call may be unnecessary as the problem can be solved remotely.

The DMI utility in the BIOS automatically records various information about your system configuration. Information about the type and speed of CPU, type and amount of memory for each memory slot, BIOS revision level, types of add-in PCI boards and components, certain revision numbers of hardware installed, etc. are automatically detected and stored in the DMI pool, which is a part of the system board's Plug and Play BIOS. Additional information, such as ISA based peripherals, which may not be automatically detected, can be manually recorded in the DMI pool by using the Add DMI menu. The DMI pool data is then verified or updated whenever the system hardware or setup is altered.

Running the DMI Utility

To run the DMI utility, type: DMICFG.EXE. You can download this utility from http://www.dfiweb.com - BIOS & DRIVERS section or ftp.dfiusa.com - /pub/DMI directory.

The DMI utility must run in real mode with at least 180K of base memory. Memory managers like HIMEM.SYS (required by Windows) must not be installed. You may do this by using one of the 3 methods listed below.

1. Boot up from a system diskette without the AUTOEXEC.BAT and CONFIG.SYS files,

2. “REM” HIMEM.SYS in the CONFIG.SYS, or

3. Press <F5> during bootup to bypass your AUTOEXEC.BAT and CONFIG.SYS files.

Installation Instructions

Page 58

Installation Instructions

This chapter summarizes the steps to install the system board into your system unit. It also includes a description of the area in which you must work and directions for memory installation. Before installing the system board, obtain the memory you plan to install. Refer to the System Memory section for the number and type of memory modules needed for the amount of memory you require.

Preparing the Area

Before unpacking the system board, make sure the location you have selected is relatively free of dust and static electricity. Excessive exposure to dust, static electricity, direct sunlight, excessive humidity, extreme cold, and water can damage the operational capabilities of your system board. Avoid placing the unit on surfaces such as carpeted floors. These areas also attract static electricity which can damage some circuits on your system board.

Make sure the power source has a properly grounded, threepronged socket. It is essential that the power connection be properly grounded for correct functioning of your system board. For further protection, we recommend that you use a surge suppressor. This will protect the system board from damage that may result from a power surge on the electrical line.

Move items that generate magnetic fields away from your system board since magnetic fields can also damage your system board. Once you have selected the ideal location, unpack the system board carefully.

Handling the System Board

It is quite easy to inadvertently damage your system board even before installing it in your system unit. Static electrical discharge can damage computer components without causing any signs of physical damage. You must take extra care in handling the system board to ensure against electrostatic build-up.

Static Electricity Precautions

1. To prevent electrostatic build-up, leave the board in its anti-static bag until you are ready to install it.

Page 59

586ITXD System Board User’s Manual

2. Wear an antistatic wrist strap.

3. Do all preparation work on a static-free surface with the system board components facing up.

4. Hold the system board only by its edges. Be careful not to touch any of the components, contacts or connections, especially gold contacts, on the board.

5. Avoid touching the pins or contacts on all modules and connectors. Hold modules and connectors by their ends.

Warning:

Electrostatic discharge (ESD) can damage your processor, disk drives, add-in boards, and other components. Perform the upgrade instruction procedures described at an ESD workstation only. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the system chassis. If a wrist strap is unavailable, establish and maintain contact with the system chassis throughout any procedures requiring ESD protection.

Floppy Disk Drive Controller

The system board is equipped with a shrouded floppy disk header that supports two standard floppy disk drives. You can install any 360KB, 720KB, 1.2MB, 1.44MB, or 2.88MB floppy disk drives. To prevent improper floppy cable installation, the shrouded floppy disk header has a keying mechanism. The 34-pin connector on the floppy cable can be placed into the header only if pin 1 of the connector is aligned with pin 1 of the header. Make sure “Onboard FDC Controller” in the Integrated Peripherals Setup of the Award BIOS is enabled.

Connecting the Floppy Disk Cable

1. Install the 34-pin header connector into the shrouded floppy disk header (J14) on the system board. The colored edge of the ribbon should be aligned with pin 1 of connector J14.

2. Install the other 34-pin header connector(s) into the disk drive(s). Align the colored edge of the daisy chained ribbon cable with pin 1 of the drive edge connector(s). The end-most connector should be attached to the drive you want to designate as Drive A.

IDE Hard Disk Interface

The system board is equipped with two shrouded PCI IDE headers that will interface four Enhanced IDE (Integrated Drive Electronics) hard disk drives.

Page 65

586ITXD System Board User’s Manual

Connecting the IDE Hard Disk Interface

To prevent improper IDE cable installation, each shrouded PCI IDE header has a keying mechanism. The 40-pin connector on the IDE cable can be placed into the header only if pin 1 of the connector is aligned with pin 1 of the header.

Header

Note:

An IDE cable with a standard 40-pin connector (without the keying mechanism) can be installed in the shrouded IDE header. Be extremely careful to match the colored edge of the ribbon with pin 1 of the header.

Connecting the Hard Disk Cable

1. If you are connecting two hard drives, install the 40-pin connector of the IDE cable into the primary shrouded IDE header (connector J16). If you are adding a third or fourth IDE device, install the 40pin connector of the other IDE cable into the secondary shrouded IDE header (connector J15).

2. Install the other 40-pin header connector(s) into the device with the colored edge of the ribbon cable aligned with pin 1 of the drive edge connector(s).

Note:

Refer to your disk drive user’s manual for information about selecting proper drive switch settings.

Page 66

Connecting Cables

Adding a Second IDE Hard Drive

When using two IDE drives, one must be set as the master and the other as the slave. Follow the instructions provided by the drive manufacturer for setting the jumpers and/or switches on the drives.

We recommend that you use Enhanced IDE or ATA-2 and ATA-3 hard drives be from the same manufacturer. In a few cases, drives from two different manufacturers will not function properly when used together. The problem lies in the hard drives, not the system board.

Important:

If you encountered problems while using an ATAPI CD-ROM drive that is set in Master mode, please set the CD-ROM drive to Slave mode. Some ATAPI CD-ROMs may not be recognized and cannot be used if incorrectly set in Master mode.

Preparing an IDE Drive for Use

IDE disk drives are already low-level formatted, with any bad-track errors entered, when shipped by the drive manufacturer. Do not attempt to do a low-level format or you may cause serious damage to the drive.

To use an IDE drive, you need to enter the drive type (this information is provided by the drive manufacturer) into the system’s CMOS setup table. Then run FDISK and FORMAT provided with your operating system. You may also use the “IDE HDD Auto Detection” function which will allow the BIOS to auto detect your hard drive type. Refer to the Chapter 2 - IDE HDD Auto Detection section for details.

Warning:

Do not run FDISK and FORMAT programs on a drive that has already been formatted or you will lose all programs and data stored on the drive.

Troubleshooting Checklist

This chapter of the manual is designed to help you with problems that you may encounter with your personal computer. To efficiently troubleshoot your system, treat each problem individually. This is to ensure an accurate diagnosis of the problem in case a problem has multiple causes.

Some of the most common things to check when you encounter problems while using your system are listed below.

1. The power switch of each peripheral device is turned on.

2. All cables and power cords are tightly connected.

3. The electrical outlet to which your peripheral devices are connected is working. Test the outlet by plugging in a lamp or other electrical device.

4. The monitor is turned on.

5. The display’s brightness and contrast controls are adjusted properly.

6. All add-in boards in the expansion slots are seated securely.

7. Any add-in board you have installed is designed for your system and is set up correctly.

Monitor/Display

If the display screen remains dark after the system is turned on:

1. Make sure that the monitor’s power switch is on.

2. Check that one end of the monitor’s power cord is properly attached to the monitor and the other end is plugged into a working AC outlet. If necessary, try another outlet.

3. Check that the video input cable is properly attached to the monitor and the system’s display adapter.

4. Adjust the brightness of the display by turning the monitor’s brightness control knob.

The picture seems to be constantly moving.

1. The monitor has lost its vertical sync. Adjust the monitor’s vertical sync.

2. Move away any objects, such as another monitor or fan, that may be creating a magnetic field around the display.

3. Make sure your video card’s output frequencies are supported by this monitor.

The screen seems to be constantly wavering.

1. If the monitor is close to another monitor, the adjacent monitor may need to be turned off. Fluorescent lights adjacent to the monitor may also cause screen wavering.

Power Supply

When the computer is turned on, nothing happens.

1. Check that one end of the AC power cord is plugged into a live outlet and the other end properly plugged into the back of the system.

2. Make sure that the voltage selection switch on the back panel is set for the correct type of voltage you are using.

3. The power cord may have a “short” or “open”. Inspect the cord and install a new one if necessary.

Floppy Drive

The computer cannot access the floppy drive.

1. The floppy diskette may not be formatted. Format the diskette and try again.

2. The diskette may be write-protected. Use a diskette that is not write-protected.

3. You may be writing to the wrong drive. Check the path statement to make sure you are writing to the targeted drive.

4. There is not enough space left on the diskette. Use another diskette with adequate storage space.

Troubleshooting

Hard Drive

Hard disk failure.

1. Make sure the correct drive type for the hard disk drive has been entered in the BIOS.

2. If the system is configured with two hard drives, make sure the bootable (first) hard drive is configured as Master and the second hard drive is configured as Slave. The master hard drive must have an active/bootable partition.

Excessively long formatting period.

1. If your hard drive takes an excessively long period of time to format, it is likely a cable connection problem. However, if your hard drive has a large capacity, it will take a longer time to format.

Parallel Port

The parallel printer doesn’t respond when you try to print.

1. Make sure that your printer is turned on and that the printer is on-line.

2. Make sure your software is configured for the right type of printer attached.

3. Verify that the onboard LPT port’s I/O address and IRQ settings are configured correctly.

4. Verify that the attached device works by attaching it to a parallel port that is working and configured correctly. If it works, the printer can be assumed to be in good condition. If the printer remains inoperative, replace the printer cable and try again.

586ITXD System Board User’s Manual Serial Port

The serial device (modem, printer) doesn’t output anything or is outputting garbled characters.

1. Make sure that the serial device’s power is turned on and that the device is on-line.

2. Verify that the device is plugged into the correct serial port on the rear of the computer.

3. Verify that the attached serial device works by attaching it to a serial port that is working and configured correctly. If the serial device does not work, either the cable or the serial device has a problem. If the serial device works, the problem may be due to the onboard I/O or the address setting.

4. Make sure the COM settings and I/O address are configured correctly.

Keyboard

Nothing happens when a key on the keyboard was pressed.

1. Make sure the keyboard is properly connected.

2. Make sure there are no objects resting on the keyboard and that no keys are pressed during the booting process.

System Board

1. Make sure the add-in card is seated securely in the expansion slot. If the add-in card is loose, power off the system, re-install the card and power up the system.

2. Check the jumper settings to ensure that the jumpers are properly set.

3. Verify that all SIMMs are seated securely into the SIMM sockets.

4. Make sure the SIMMs are in the correct locations.

5. If the board fails to function, place the board on a flat surface and seat all socketed components. Gently press each component into the socket.

6. If you made changes to the BIOS settings, re-enter setup and load the BIOS defaults.
