Introduction
Damage Free Intelligence
•Monitors processor temperature and overheat alarm.
If the temperature of the processor is over 85oC, an alarm will
sound and the Green LED will illuminate warning you of system
overheat.
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.
Refer to the Clearance Requirements section in Chapter 2 of
this manual.
- The chassis or cabinet has poor ventilation.
•Monitors 5V and 12V power voltages and failure alarm.
The 586ITBD is able to detect the output voltage of your

586ITBD System Board User’s Manual
This chapter summarizes the steps to install the 586ITBD 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 586ITBD
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.
14
Page 15
Hardware Installation
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.

System Memory
The 586ITBD 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 586ITBD 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 586ITBD system board can
support 8MB to 64MB memory using 1MBx64, 2MBx64 or
4MBx64 DIMM. The table below shows the supported DIM
modules and their corresponding memory sizes.
DIMMs
1MBx64

SIMM
The SIM sockets are divided into
two banks on the system board,
Bank 0 and Bank 1. Each bank
consists of 2 SIMM sockets.
Your system board supports 8MB
to 256MB of memory using
1MBx32, 2MBx32, 4MBx32,
8MBx32 or 16MBx32 72-pin
SIMMs (Single In-line Memory
Module). You will need 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 banks but you must populate one bank first before going to
the next bank.

Cache Memory
The 586ITBD system board supports 512KB pipeline burst, direct
map write-back cache installed at locations U8 and U9 of the system board. One SRAM is mounted on location U10 for tag SRAM
to store the cacheable addresses. Refer to page 17 for the locations
of the SRAMs and tag SRAM.
Processor Upgrade Information
Your computer 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.
Jumpers JP1, JP3, JP4, JP8, JP10 and JP11 are used to set the external
bus clock of your processor. The clock generator will determine the
external bus clock that must be sent to the processor through
these settings.
After setting these jumpers, 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.
2
Jumper JP9 is used to set the voltage of your processor. Make sure
these jumpers are set correctly, otherwise your system will hang.
The table below shows the External System Bus Clock of the
processors supported by the system board and their corresponding
PCI Clock and ISA Bus Clock.

Hardware Installation
Installing Upgrade Processors
The 586ITBD is equipped with a 321-pin Zero Insertion Force
(ZIF) socket at location U11 of the system board. Refer to page 17
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.

586ITBD 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.

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.
Pin 1

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.
Pin 1
Positioning the Processor 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 processor in the socket. This is normal and
will not damage the processor. However, if the handle is not
completely closed, damage to the processor and/or system
board may result.

586ITBD System Board User’s Manual
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).

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 J22). 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 J18).
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 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 586ITBD
system board.

586ITBD System Board User’s Manual
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 3 - 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.

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.
3
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.

PIO means Programmed Input/Output. Rather than have the BIOS
issue a series of commands to effect a transfer to or from the disk
drive, PIO allows the BIOS to tell the controller what it wants and
then let the controller and the CPU perform the complete task by
themselves. Your system supports five modes, 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select the
best available mode after checking your 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.
84
Page 85
Troubleshooting
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.
D
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.
85
Page 86
D
586ITBD System Board User’s Manual
4. There is not enough space left on the diskette. Use another
diskette with adequate storage space.
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.
86
Page 87
Troubleshooting
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.
D
1. Make sure the keyboard is properly connected.
2. Make sure there are no objects resting on the keyboard and
