Introduction

The 586ITX, equipped with a 321-pin Zero Insertion Force (ZIF) CPU
socket, is a Pentium processor-class system board supporting Intel
Pentium processors running at 90MHz, 100MHz, 120MHz, 133MHz,
150MHz, 166MHz and 200MHz frequencies. The 586ITX also supports
Intel Pentium processor with MMX™ technology - 166/200/233MHz, fu-
ture Intel Pentium OverDrive processors, AMD-K5™ PR90/PR100/
PR120/PR133/PR166, and AMD-K6™ PR2-166/PR2-200/PR2-233.

The 586ITX system board can support 8MB to 256MB of system
memory. It is equipped with two DIMM sockets using x64 EDO, fast
page mode or SDRAM, and 4 SIMM sockets using EDO or fast page
mode x32 DRAM. This system board also supports 512KB pipeline
burst SRAM.

The 586ITX system board can support ACPI Specification, Modem
Wake-Up, PC 97 Compliance, and Dual Function Power Button to en­hance its performance. ACPI (Advanced Configuration Power Interface)
has energy saving features which enable operating systems to reliably
manage and coordinate power planes, PnP (Plug-and-Play) peripherals,
and cooling fans. ACPI is the specification of Microsoft's anticipated
PC 97 "OnNow" design allowing continual "power on" with reduced en­ergy consumption. The Modem Wake-Up feature allows the "sleeping"
PC to power on to respond to incoming calls.

PC 97 Compliance defines the adherence to Plug-and-Play compatibil­ity, hardware power management, and 32-bit device drivers for Win­dows 95 & Windows NT specifications. Dual Function Power Button
allows two distinct OFF modes. In Sleep mode, a PC powers down but
not off. In Soft-Off, a PC shuts down but requires a reboot to "awaken"
it.

The 586ITX design is based on the Peripheral Component Interconnect
(PCI) local bus and Industry Standard Architecture (ISA) standards. It is
equipped with 3 dedicated PCI slots, 2 dedicated 16-bit ISA slots and 1
shared PCI/ISA slot.

5

The 586ITX is equipped with two NS16C550A-compatible serial ports,
an SPP/ECP/EPP parallel port, a shrouded floppy disk header, and two
shrouded PCI IDE headers with bus mastering capabilities that highly
reduce CPU use during disk transfer. This system board is also
equipped with one mini-DIN-6 PS/2 mouse port, one mini-DIN-6 PS/2
keyboard port, two USB ports and one IrDA connector for wireless con­nectivity between your computer and peripheral devices.

The 586ITX 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.

Chapter 2

Hardware Installation

This chapter summarizes the steps to install the 586ITX 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, 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 586ITX 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.

9

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 586ITX 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.

10

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 586ITX from its original packing box. Be careful to
avoid touching all connectors and pins on the board. Please refer to
the handling instructions on pages 9-10 for proper handling tech­niques.

6. Insert the memory modules into the memory banks on the 586ITX. The
quantity and location of the memory modules depends on the
memory configuration and type of modules you intend to use.

7. Install the CPU. Be sure pin 1 of the CPU is aligned with pin 1 of
the socket.

8. Set the corresponding jumpers.

9. Install the prepared 586ITX system board into the case and replace
the screws.

10. Reinstall all cards and connectors and replace the system unit

cover. Reconnect all power cords and cables.

To use an ATX power supply, install
the 20-pin ATX power cable con­nector into location CN8 on the sys­tem board. The 20-pin connector
can be inserted into CN8 only if pin
1 of the connector is aligned with
pin 1 of CN8.

System Memory

The 586ITX system board supports two kinds of memory modules:
DIMM and SIMM. DIMM, which uses SDRAM, performs better than
SIMM, which uses DRAM. Refer to page 12 for the locations of the DIM
and SIM sockets.

Important:

DIM and SIM modules can not exist on the 586ITX system board at the
same time. Use either SIMM or DIMM only.

DIMM

The two 168-pin DIMM (Dual In-line Memory Module) sockets use x64
EDO, FPM and SDRAM. The 586ITX system board can support 8MB to
32MB memory using 1MBx64, 2MBx64 or 4MBx64 DIMM. The table
below shows the supported DIM modules and their corresponding
memory sizes.

1. Pull the “tabs” which are at the ends of the socket to the side.

2. Position the DIMM above the socket with the “notches” in the mod­ule aligned with the “keys” on the socket.

3. Seat the module vertically into the socket. Make sure it is com­pletely seated. The tabs will hold the DIMM in place.

SIMM

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. The system board will not work
if you install 1 or 3 pieces. 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.

1. Position the SIMM above the socket with the “notch” in the module
aligned with the “key” on the socket.

2. Seat the module at a 45° angle into the bank. Make sure it is com­pletely seated. Tilt the module upright until it locks in place in the
socket.

Cache Memory

The 586ITX system board can sup­port 512KB pipeline burst, direct
map write-back cache SRAM. Your
system board may come with
512KB cache, which is the maxi­mum cache memory supported by
the system board, mounted at loca­tions U5 and U6. One SRAM is
mounted on location U7 for tag
SRAM to store the cacheable ad­dresses.

Processor Installation

The 586ITX allows for easy installa­tion of 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.

Jumper JP20 is used to set the exter­nal bus clock of your processor. Re­fer to the following pages for the
external bus clock that corresponds to your processor and set this jumper
accordingly. The clock generator will determine the external bus clock that
must be sent to the processor through this setting.

Jumper JP1 and JP2 are used to set the frequency ratio of your processor.
Refer to the following pages for the frequency ratio that corresponds to your
processor and set these jumpers accordingly.

After setting these jumpers, an Intel processor will multiply the external bus
clock by the frequency ratio to become the internal clock speed. Internal

18

clock speed is the commonly used 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).

AMD processors use the PR-rating system which is the overall processor
performance rating. Under the system, these processors slightly outperform
Intel’s Pentium processors.

Jumpers JP13 and JP15 are used to set the voltage of your processor.
Make sure these jumpers are set correctly, otherwise your system will hang.

Installing Upgrade CPUs

The 586ITX is equipped with a 321­pin Zero Insertion Force (ZIF)
socket at location U1 of the system
board. This socket is designed for
easy removal of an old CPU and
easy insertion of an upgrade CPU.
The ZIF socket allows you to care­fully place the new CPU into its po­sition. If you need to apply exces­sive force to insert the CPU, you
are not installing the CPU correctly.

Warning:

Open the socket only if you are actually installing a CPU. The warranty
on the original CPU 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 CPU installation, the ZIF socket has a Plug/Keying
mechanism. Several holes in the socket are plugged so that the CPU
will go in only one way. If you cannot easily insert the CPU, verify that
pin 1 of the CPU is aligned with pin 1 of the socket.

Zero Insertion Force (ZIF) Socket

22

To install an upgrade CPU, 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 CPU carefully by
lifting it straight out of the socket. You are now ready to insert the
new CPU.

Pin 1

23

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

Pin 1

Positioning the CPU Above the ZIF Socket

4. Push the handle down until the handle locks into place. The top
plate will slide forward. You will feel some resistance as pressure
starts to secure the CPU in the socket. This is normal and will not
damage the CPU. However, if the handle is not completely closed,
damage to the CPU and/or system board may result.

Installing A Fan/Heatsink

You must choose a fan/heatsink suitable for the processor installed on
your system board. Position the fan/heatsink on the CPU 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.

24

Clearance Requirements

Your CPU comes with a heatsink mounted on top. To maintain proper
airflow once the upgrade is installed on the system board, the CPU and
heatsink require certain space clearances. The clearance above the
CPU’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 CPU and its airspace.

Fan Exhaust

The CPU 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).

(default)

With a modem being installed, you can remotely transmit or access
data without physically going to your system. To “wake up” your sys­tem, follow the steps below.

1. If your ATX power supply has an On/Off switch, set this to On so
that even when you have shut down your system, it will always
remain in “standby” mode.

2. Enable Power Management. This will allow your system to enter
Suspend mode after you have finished accessing data. Refer to the
Power Management Setup section for more information.

3. Set Jumper JP21 accordingly. This will depend on the COM port
where your modem is connected.

Important:

Before connecting your cable to COM1 or COM2 (depending on your
setting), you must turn on the power of modem first to avoid your ATX
power supply being interfered.

Factory Testing Jumpers

The jumpers below are for factory testing only and should always be set
to their default configuration. Reconfiguring these jumpers will cause
problems with your system board.

board. These built-in serial ports
are RS-232C asynchronous com­munication ports with 16C550A­compatible UARTs that can be used
with modems, serial printers, re­mote display terminals, and other
serial devices.

Parallel Port

The 586ITX system board has a
standard printer port (CN7) 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).

Floppy Disk Drive Controller

The 586ITX 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.

Connecting the Floppy Disk Cable

1. Install the 34-pin header con­nector into the shrouded floppy
disk header (CN2) on the sys­tem board. The colored edge of
the ribbon should be aligned
with pin 1 of connector CN2.

29

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 586ITX system board is equipped with two shrouded PCI IDE
headers that will interface four Enhanced IDE (Integrated Drive Elec­tronics) hard disk drives.

Note:

Only Enhanced IDE hard drives or ATAPI CD-ROMs can be connected
to the IDE interface.

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 PCI IDE header. Be ex­tremely careful to match the colored edge of the ribbon with pin 1 of the
header.

30

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 J8).

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 a few cases, drives from two different manufacturers
will not function properly when used together. The problem lies in the
hard drives, not the 586ITX system board.

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.

31

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.

Using 586ITX 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.

Universal Serial Bus Connectors

The 586ITX system board is
equipped with two connectors, at
locations JP8 (USB 1) and JP9
(USB 2) 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. Mount the card-edge bracket to the system chassis.

32

Connect the cable to JP8 and JP9 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 JP8 and JP9. Pin 5 of JP8 has been removed and the hole in the USB
cable connector, which corresponds to pin 5, has been plugged to prevent
incorrectly inserting the connector. Make sure “USB Controller” in the Inte­grated Peripherals setup of the Award BIOS is Enabled.

USB port cables (optional)

IrDA Connector

The 586ITX system board is
equipped with an IrDA connector
for wireless connectivity between
your computer and peripheral de­vices. Connect your IrDA cable to
connector CN4 on the 586ITX sys­tem board. Make sure “Onboard IR
Controller” in the Integrated Periph­erals setup of the Award BIOS is
Enabled. Carefully read this section
in Chapter 3 of this manual for in­structions prior to using your IrDA
device.

33

Installing Expansion Cards

The 586ITX system board is equipped with 3 dedicated PCI slots, 2
dedicated 16-bit ISA slots and 1 shared PCI/ISA slot. All PCI and ISA
slots are bus masters.

47

Break Event From Suspend and Reload Global Timer 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 enabled, 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.

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 make any changes to the default settings.

ESC: Skip

Enter your choice, and press <Enter> to accept the parameters or press
<Esc> to abort. The parameters of the hard disk will be displayed in the
Standard CMOS Setup.

Hard Drive Mode

The system board supports three HDD modes: Normal, LBA and Large.
If your hard disk drive does not support LBA mode, the “LBA” option will
not be displayed. If your HDD has 1024 or fewer cylinders, the “Large”
option will not be displayed. If your hard drive is larger than 2.1GB, be
sure that your operating system supports it or you may need to create
separate partitions.

55

Normal Mode

Normal mode is the generic access mode in which neither the BIOS nor
the IDE controller will make any transformations during hard-drive ac­cess.

The maximum number of cylinders, heads and sectors for Normal mode
are 1024, 16 and 63, respectively.

no. Cylinders (1024)
x no. Heads ( 16)
x no. Sectors ( 63)
x bytes per sector ( 512)

528 megabytes

If you set your HDD to Normal mode, the maximum accessible HDD will
be 528 megabytes even though the physical size of the HDD may be
greater than that.

LBA (Logical Block Addressing) Mode

LBA mode is a HDD accessing method to overcome the 528 megabyte
limitation. The number of cylinders, heads and sectors shown on the
screen may not be the actual number for the HDD.

During HDD accessing, the IDE controller will transform the logical ad­dress described by the sector, head and cylinder number into its own
physical address inside the HDD.

The maximum HDD size supported by the LBA mode is 8.4 gigabytes. It
is obtained by the following formula.

no. Cylinders (1024)
x no. Heads ( 255)
x no. Sectors ( 63)
x bytes per sector ( 512)

8.4 gigabytes

56

Large Mode

Large mode is the extended HDD access mode supported by the sys­tem board. Some IDE HDDs have more than 1024 cylinders without
LBA support (in some cases, you may not want the LBA mode). This
system board provides another alternative to support these kinds of
HDDs.

The BIOS tells the operating system that the number of cylinders is half
the actual number and that the number of heads is double the actual
number. During disk access, the reverse conversion is done by the
INT13h routine.

Maximum HDD size:

no. Cylinders (1024)
x no. Heads ( 32)
x no. Sectors ( 63)
x bytes per sector ( 512)

1 gigabyte

Note:

To support LBA or Large mode, address translation software is included
in the Award BIOS HDD Service Routine (INT13h). If you are running
an operating system that bypasses the BIOS INT13 Service Routine,
LBA and Large Mode may fail.

HDD Low Level Format

The HDD Low Level Format utility is designed as a tool to save you

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.

64

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.

65

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.
