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.
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 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.

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
