Chapter 2
Hardware Installation
This chapter summarizes the steps to install the G586SPB AIO 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 in-
stalling the system board, obtain the memory you plan to install. Please
refer to the information on pages 13 and 14 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 expo-
sure to dust, static electricity, direct sunlight, excessive humidity, ex-
treme 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 sys-
tem 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 G586SPB AIO 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.

10
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 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 anti-
static 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 G586SPB AIO system board, the following out-
lines 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

11
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 instruc-
tions if necessary.
3.Detach all connectors from the old system board and remove ex-
pansion 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 G586SPB AIO 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 tech-
niques.
6.Insert the memory modules into the memory banks on the
G586SPB AIO. The quantity and location of the memory modules
depends on the memory configuration and type of modules you in-
tend to use.
7.Insert the cache module, if any, into the cache module slot on the
G586SPB AIO. 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 G586SPB AIO system board into the case and
replace the screws.

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. Refer to page 12 for the locations of the 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 G586SPB AIO system board can support 8MB to 256MB of
memory using 1MBx32, 2MBx32, 4MBx32, 8MBx32, or 16MBx32 72-pin
SIMMs. The table below shows the supported SIM modules and their
corresponding memory sizes.

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 com-
pletely seated. Tilt the module upright until it locks in place in the
socket.
Cache Memory
The G586SPB AIO system board can support 256KB or 512KB pipeline
burst, direct map write-back cache SRAM. Your system board may
come with 256KB or 512KB cache mounted at locations U4 and U6 of
the system board. If your system board is mounted with 256KB cache,
you may upgrade your cache memory to 512KB by installing a 256KB
cache module in the 160-pin cache module slot (KM1). Regardless of
the amount of cache memory installed, one SRAM is mounted on loca-
tion U8 for tag RAM to store the cacheable addresses. Refer to page 12
for the locations of the cache module slot (KM1), U4 and U6.
Warning:
We highly recommend that you use the T2BSM32-256 cache module. If
you are using a cache module other than the one recommended above,
make sure your cache module meets the Intel COAST 2.x specification.
Severe damage might occur on the cache module or system board if
you insert modules other than the one specified above.

Zero Insertion Force (ZIF) Socket
Installing Upgrade CPUs
The G586SPB AIO is equipped with a 321-pin Zero Insertion Force
(ZIF) socket at location U14 of the system board. Refer to page 12 for
the 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 micropro-
cessor 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 proces-
sor 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
