Chapter 2
Hardware Installation
This chapter summarizes the steps to install the 586IVX 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 586IVX 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 586IVX 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.

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 586IVX 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 586IVX. The
quantity and location of the memory modules depends on the
memory configuration and type of modules you intend to use.
7. Insert the cache module, if any, into the cache module slot on the
586IVX. Refer to the Cache Memory section for upgrading your
cache memory.
8. Install the CPU. Be sure pin 1 of the CPU is aligned with pin 1 of
the socket.
9. Set the corresponding jumpers.
10. Install the prepared 586IVX system board into the case and replace
the screws.
11. Reinstall all cards and connectors and replace the system unit
cover. Reconnect all power cords and cables.
If you are using an ATX power supply, install the 20-pin ATX power
cable connector into location PL1 on the system board. The 20-pin
connector can be inserted into PL1 only if pin 1 of the connector is
aligned with pin 1 of PL1.

The 586IVX system board supports One kinds of memory modules:
SIMM. , which uses DRAM. Refer to page 12 for the locations of the nd
SIM sockets.
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.
The 586IVX system board can support 8MB to 128MB of memory using
1MBx32, 2MBx32, 4MBx32, or 8MBx32 72-pin SIMMs. The table on the

Installing a SIM Module
A SIM module simply snaps into a socket on the system board. Pin 1 of
the SIM module must correspond with Pin 1 of the socket.
notch
key
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 586IVX system board can support 256KB pipeline burst, direct map
write-back cache SRAM. Your system board may come with 256KB
cache mounted at locations U11 and U17 of the system board.
16
CPU Installation
The 586IVX allows for easy installation of CPUs. Make sure all jumpers are
set correctly before applying power or you may damage the CPU or system
board. Use a needle-nosed plier to move the jumpers if necessary.
Jumpers JP10, JP11 and JP12 are 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 these jumpers accordingly. The
clock generator will determine the external bus clock that must be sent to
the processor through these settings.
Jumper JP5 is 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 this jumper 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
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).
Cyrix and AMD processors use the P-rating system which is the overall
CPU performance rating. Under the system, these processors slightly outperform Intel’s Pentium processors.
Jumpers JP2, JP3, JP4 and JP7 are used to set the voltage of your processor. Make sure these jumpers are set correctly, otherwise your system will
hang.

location of the ZIF socket. 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
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
21
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
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.
22
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.
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
23
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).
Jumper Settings for CMOS Clear

Serial Ports
The 586IVX is equipped with two serial ports at locations CN5 (COM 2)
and CN6 (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 586IVX 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).

26
Floppy Disk Drive Controller
The 586IVX 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 (J10) on the system board. The colored edge of the ribbon
should be aligned with pin 1 of connector J10.
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 586IVX 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.
27
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.
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
J11). 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 J12).
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.
28
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 586IVX 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.
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 586IVX 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 586IVX system board is equipped with two USB ports on locations
J2 and J4 on the system board. 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 set to Enabled.
29
Installing Expansion Cards
The 586IVX system board is equipped with 3 dedicated PCI slots, 3
dedicated 16-bit ISA slots and 1 shared PCI/ISA slot. All PCI slots are
bus masters. Refer to page 12 for the locations of the expansion slots.

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.
HDD
Power
Down
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.
IRQ3-IRQ15 (Wake Up Events in Doze & Standby and Power
Down & 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 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

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.
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
50
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
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.
51
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
time formatting your hard disk. It automatically looks for the necessary

Desktop Management Interface (DMI)
The 586IVX 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
53
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.
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.
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.
59
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.
60
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.
