Introduction

The 686IPK is an Intel Pentium II processor based system board using
Intel’s high performance 233MHz Pentium® II processor with 512KB ex­ternal L2 cache, 233MHz Pentium® II processor with 256KB external L2
cache or 266MHz Pentium® II processor with 512KB external L2 cache.

The 686IPK supports processor fan “failure detection” function that
monitors the status of the processor fan. It detects any irregularity in
processor fan RPM (Rotation Per Minute) and alerts you to attend to
any problem that may damage your system. The “failure detection” cir­cuit requires a processor fan that operates at greater than 3600 RPM.

The 686IPK is equipped with a switching voltage regulator that auto­matically detects 1.8V to 3.5V. The VID (Voltage Identifications) code
found in a processor allows the 686IPK to detect and adjust to the re­quired voltage.

The 686IPK system board can support 8MB to 512MB of system
memory. It is equipped with 4 SIMM sockets allowing you to install x32
or x36 EDO or fast page mode SIMMs. The x36 SIMM supports parity
checking which informs the user of memory failure and prevents error
accumulation.

The 686IPK system board is designed to fit into an ATX form factor
case. Using an ATX power supply, you can either shut down your com­puter by pressing the Power button located on the front bezel of your
computer or by executing the Shut Down command under the
Windows 95 operating system. Your system will enter the “soft power
off” state. With a modem installed, you can power on your system to
remotely transmit or access data. An ATX power supply also provides
adequate airflow throughout the chassis to prevent overheating the pro­cessor.

Chapter 2
Hardware Installation

This chapter summarizes the steps to install the 686IPK system board
into your system unit. It also includes a description of the area in which
you must work and directions for processor and memory installation.
Before installing the system board, carefully read the Installing the Sys­tem Board section for proper installation procedures.

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. Place the system board on a workbench (not in a chas­sis). 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, three-pronged
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 686IPK 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.

8

Static Electricity Precautions

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

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 by its edges only. 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.

Installing the System Board

If you are installing the 686IPK system board, the following outlines the
basic installation steps. Before installing the system board into your sys­tem unit, you should prepare the tools you will need.

You will need:

• One medium size, flat-bladed screwdriver

• One medium Phillips screwdriver

• One needle-nosed pliers

• One small nutdriver

1. Unlock your system unit. Turn off the power and disconnect all
power cords and cables.

9

2. Remove the system unit cover. Refer to the manufacturer’s instruc­tions if necessary.

3. Detach all connectors from the old system board and remove ex­pansion cards seated in any expansion slots.

4. Loosen the screws holding the original system board and remove
the board from the system. Save the screws.

5. Remove the 686IPK from its original packing box. Be careful to
avoid touching all connectors and pins on the board. Refer to the
handling instructions on pages 8-9 for proper handling techniques.

6. Place the system board on a flat surface (not in a chassis) with the
component side facing up.

7. Install the retention mechanism that comes with the package. Refer
to the Installing the Retention Mechanism section for installation in­structions.

8. You are now ready to install the Intel Pentium II processor. Before
you install the processor, carefully read the installation instructions
under the Intel Pentium II Processor Installation section.

Note:

Make sure the system board is not yet installed with any SIMMs,
add-in cards, cables, etc.

9. Insert the memory modules into the memory banks on the 686IPK. The
quantity and location of the memory modules depends on the
memory configuration and type of modules you intend to use.

10. Set the corresponding jumpers.

11. Install the prepared 686IPK system board into the case. Make sure
you install screws into the four mounting holes shown on the next
page.

System Memory

The SIMM (Single In-line Memory Module)
sockets are divided into two banks on the
system board, Bank 0 and Bank 1. Each
bank consists of 2 SIMM sockets. You will
need either 2 or 4 pieces of SIM modules,
depending on the amount of memory you
intend to install. Make sure you insert the
same type of SIMMs in one bank.

You can install SIMMs in either of the banks, Bank 0 or Bank 1, but you
must populate one bank first before going to the next bank.

The 686IPK system board can support 8MB to 512MB of memory using
1MBx32/x36, 2MBx32/x36, 4MBx32/x36, 8MBx32/x36, 16MBx32/x36 or
32MBx32/x36 72-pin SIMMs. The table below shows the supported SIM

Intel Pentium® II Processor Installation

Installing the Retention Mechanism

The 686IPK package includes a Retention Mechanism. The Retention
Mechanism is used to hold an Intel Pentium® II processor to the Intel
Slot 1 connector. Make sure the system board is on a workbench (not
in a chassis). To install the Retention Mechanism, follow the steps be­low.

1. The Retention Mechanism package includes a Retention Mecha­nism and two Retention Mechanism Attach Mounts.

®

2. Insert the Retention Mechanism Attach Mount through the holes,
up from the bottom of the system board. The holes are located near
the ends of the Intel® Slot 1 connector.

18

3. Hold the Retention Mechanism upright and position it above the
Intel® Slot 1 connector.

4. Slide the Retention Mechanism downward so that the rectangular
hole at the center of the Retention Mechanism fits onto the connec­tor. The captive nuts located on both ends of the Retention Mecha­nism will also fit over the threaded studs of the Retention Mecha­nism Attach Mount.

Note:

The holes on the upper sides of the Retention Mechanism (where
the latches of the processor locks) should be facing toward the Intel
chips.

5. Tighten the captive nuts to stabilize the Retention Mechanism.

19

Installing Boxed Processor

1. Mount the two black plastic pegs onto the system board. These
pegs will be used to attach the fan heatsink supports. Notice that
one hole and the base of one peg are larger than the other hole
and peg base. Push each peg into its hole firmly until you hear it
“click” into place.

2. Slide a black plastic heatsink support onto each end of the fan
heatsink, making sure that the hole and clip are on the outside
edge of the support. (If the supports are reversed, the holes will not
line up with the pegs on the system board). Slide each heatsink
support toward the center of the processor until the support is
seated in the outside groove in the fan housing.

20

3. Slide the clip (A) on each support toward the processor, exposing
the hole that will fit over the peg on the system board. Push the
latches (B) on the processor toward the center of the processor
until they click into place.

4. Hold the processor so that the fan shroud is facing toward the pegs
on the system board. Slide the processor (C) into the Retention
Mechanism and slide the supports onto the pegs. Ensure that the
pegs on the system board slide into the holes in the heatsink sup­port and that the alignment notch in the processor fits over the plug
in Slot 1. Push the processor down firmly, with even pressure on
both sides of the top, until it is seated.

5. Slide the clips on the supports (A) forward until they click into place
to hold the pegs securely. (Apply slight pressure on the peg and
push the peg toward the clip while pushing the clip forward.) Push
the latches on the processor (B) outward until they click into place
in the Retention Mechanism. The latches must be secured for
proper electrical connection of the processor.

6. Attach the small end of the power cable (C) to the three-pin con­nector in the processor, then attach the large end to the three-pin
connector (J4 - fan connector) on the system board.

21

Removing the Processor

To remove the processor from the system board, follow these steps (the
reverse of the installation process).

1. Disconnect the fan power cable from the system board. (We recom­mend that you leave the cable connected to the processor).

2. Slide the clips on the supports backward to release the pegs in the
system board. Push the latches on the processor toward the center
of the processor until they click into place.

3. Lift one end of the processor until it is freed from Slot 1. Lift the
other end of the processor until it is freed from Slot 1. Lift the entire
processor (with the fan heatsink supports attached) until it is free
from the Retention Mechanism.

4. Remove the heatsink support pegs from the system board and dis­card them. With one hand, squeeze together the two halves of the
peg on the bottom side of the system board. With the other hand,
pull the peg out of the hole in the system board. Do not reuse the
pegs.

Caution:

When handling the processor, avoid placing direct pressure on the label
area of the fan. When removing the processor, avoid pressing down on
the system board or components. Instead, press down on plastic con­nectors.

22

Installing OEM Processor

If you are using Intel Pentium® II processor in OEM package, please
follow the steps below.

1. Your OEM package may include the following items.

Important:

• Make sure your heatsink is attached with a fan to prevent
overheating the processor.

• Contact your heatsink manufacturer to check whether your pro­cessor requires a Heatsink Support (HSS) installed on the sys­tem board.

2. Push the HSS Top Bar sideways to free the HSS Top Bar from the
retaining “tabs” of the HSS Base.

23

3. Remove the HSS Pins located on each end of the HSS Base.

4. Install the HSS Base by pushing each side down firmly into the
holes on the system board. (The HSS Base can only be installed in
one direction). Make sure it locks into place.

5. Replace the HSS Pins on each end of the HSS Base. These pins
will insert through the HSS Base to secure it to the system board.

6. Hold the processor and push the latches toward the center of the
processor until they click into place.

7. Hold the processor so that the heatsink is facing toward the HSS
Base on the system board. Slide the processor into the Retention
Mechanism. Ensure that the alignment notch in the processor fits
into the plug in Slot 1. Push the processor down firmly, with even
pressure on both sides of the top, until it is seated.

24

8. Push the latches on the processor outward until they click into
place in the Retention Mechanism. The latches must be secured for
proper electrical connection of the processor.

9. Slide the HSS Top Bar into the heatsink until it locks into place.

10. Attach the small end of the power cable (C) to the three-pin con­nector in the processor, then attach the large end to the three-pin
connector (J4 - fan connector) on the system board.

25

Clearance Requirements

To maintain proper airflow once the processor is installed on the system
board, the processor and fan heatsink require certain space clearances.
The clearance above the processor must be at least 0.3 inches. The
clearance on at least 3 of 4 sides of the processor and fan heatsink
must be at least 0.2 inches. All cables (for floppy drive, hard drive, CD­ROM, etc.) must be routed clear of the processor and its airspace.

Fan Exhaust

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

Serial Ports

The 686IPK is equipped with two serial
ports at locations CN1 (COM 2) and CN5
(COM 1) of the system board. These built-in
serial ports are RS-232C asynchronous
communication ports with 16C550A-compat­ible UARTs that can be used with modems,
serial printers, remote display terminals,
and other serial devices.

Parallel Port

The 686IPK system board has a standard
printer port (CN2) for interfacing your PC to
a parallel printer. It supports SPP, ECP and
EPP modes. You can set the port’s mode in
the Integrated Peripherals setup of the
Award BIOS (Refer to Chapter 3).

The parallel port on your system board can be set to any of the follow­ing system I/O addresses:

I/O Address

3BC-3BE Hex
378-37A Hex (default)
278-27A Hex

Floppy Disk Drive Controller

The 686IPK 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 drive. 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.

Connecting the Floppy Disk Cable

1. Install the 34-pin header connector into
the shrouded floppy disk header (J5) on
the system board. The colored edge of
the ribbon should be aligned with pin 1
of connector J5.

30

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 686IPK system board is equipped with two shrouded PCI IDE
headers that will interface four Enhanced IDE (Integrated Drive Elec­tronics) hard disk drives.

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.

IDE cable

Header

Note:

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

31

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 J7). If you are add­ing a third or fourth IDE device, install
the 40-pin connector of the other IDE
cable into the secondary shrouded IDE
header (connector J6).

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.

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 hard drives from the same
manufacturer. In some cases, drives from two different manufacturers
will not function properly when used together. This occurs due to hard
drive incompatibility, not a problem with the 686IPK system board.

Using 686IPK with CD-ROM Drives

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.

32

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 DOS. 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 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.

Universal Serial Bus Connectors

The 686IPK system board is equipped with a connector, at location J1
on the system board, for external USB ports. USB allows data ex­change between your computer and a wide range of simultaneously ac­cessible peripherals. Make sure “USB Controller” in the Integrated Pe­ripherals setup of the Award BIOS is Enabled.

Connecting the USB Ports

As an option, one card-edge bracket mounted with two USB port cables
may be provided with the system board. The ends of the cables are
attached to a connector. Connect the USB cable connector to J1 on the
system board. The USB port cables can be inserted only if pin 1 of the
cable (red wire) is aligned with pin 1 of J1. Pin 9 of J1 has been re­moved and the hole in the USB cable connector, which corresponds to
pin 9, has been plugged to prevent incorrectly inserting the connector.
Mount the card-edge bracket to the system chassis.

USB port cables (optional)

IrDA Connector

The 686IPK system board is equipped with an IrDA connector for wire­less connectivity between your computer and peripheral devices. Con­nect your IrDA cable to connector J2 on the 686IPK system board.
Make sure “Onboard IR Controller” in the Integrated Peripherals setup
of the Award BIOS is Enabled. Carefully read this section (Onboard IR
Controller) in Chapter 3 of this manual for instructions prior to using
your IrDA device.

Fan Connector

We highly recommend that you attach a fan to the heatsink of your
processor to prevent overheating the processor. The 686IPK system
board supports processor fan “failure detection” function. To use this
function, your processor fan must also support this feature. The “failure
detection” circuit requires a processor fan that operates at greater than
3600 RPM. If your fan fails to function, it will alert you to attend to any
problem that may damage your system or processor. Jumper JP5 must
be set to On to enable this function. Refer to the Jumper Settings for
Processor Fan Failure Detection section for more information.

Connecting the Fan

Connect the fan’s power cable to J4 on the system board. Please note ­the connector on your fan must be a 3-pin connector and the third pin
an “open collector” type.

These Green PC power saving categories are user configurable only
when the Power Management category is set to User Defined. They are
used to define the idle time that elapses before the system enters the
power saving mode.

When enabled and after the set time of system inactivity, the
CPU clock will run at a slower speed (1/2 of full speed) while
all other devices still operate at full speed.

When enabled and after the set time of system inactivity, the
CPU clock will run at a speed slower than the speed during
Doze mode (1/3 of full speed) while all other devices still oper­ate at full speed.

When enabled and after the set time of system inactivity, the
CPU and onboard peripherals will be shut off.

This is used to define the continuous HDD idle time that
elapses before the HDD enters the power saving mode (motor
off). When enabled and after the set time of system inactivity,
the hard disk drive will be powered down while all other de­vices remain active.

51

IRQ3 to IRQ15 (Wake Up Events in Doze and Standby, and
Power Down and Resume Events)

These are I/O events whose occurrence can prevent the system from
entering a power saving mode or can awaken the system from such a
mode. In effect, the system remains alert for anything which occurs to a
device which is configured as On, even when the system is in a power
saving mode.

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. When set to On, the activity will neither prevent the system
from going into a power saving mode nor awaken it.

PNP/PCI Configuration

This section describes configuring the PCI bus system. It covers some
very technical items and it is strongly recommended that only experi­enced users should make any changes to the default settings.

The Award Plug and Play BIOS has the capacity to automatically con­figure all of the boot and Plug and Play compatible devices. However,
this capability means absolutely nothing unless you are using a Plug
and Play operating system such as Windows® 95.

Auto

Manual

The system will automatically detect the settings for you. The
categories that follow will not be shown on the PNP/PCI Con­figuration screen.

This will allow you to set the IRQ (you have assigned your
add-in card) to Legacy ISA or PCI/ISA PnP. For non-PnP ISA
cards, select Legacy ISA. For PnP ISA or PCI cards, select
PCI/ISA PnP.

Reset Configuration Data

Enabled
Disabled

The BIOS will reset the configuration data automatically.
The BIOS will not reset the configuration data.

PCI IRQ Actived By

This category is used to set the method by which the PCI bus recog­nizes that an IRQ service is being requested by a device. Under all
circumstances, you should retain the default configuration unless a dif­ferent setting is needed.

PCI IDE IRQ Map To

This category is used to configure your system to the type of IDE disk
controller in use.

Desktop Management Interface (DMI)

The 686IPK 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.dfi.com.tw - BIOS & DRIVERS section or ftp.dfiusa.com ­/pub/DMI directory.

62

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. To do this, boot up from a system diskette without
the AUTOEXEC.BAT and CONFIG.SYS files. “REM” HIMEM.SYS in the
CONFIG.SYS or press <F5> during bootup to bypass your
AUTOEXEC.BAT and CONFIG.SYS files.

Chapter 4
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.

When you encounter problems while using your system, first check that:

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.

68

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.

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 that the other end is 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”. 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 write­protected.

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.

69

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.

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.

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 on­line.

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.

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.

70

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 port 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.
