may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular in-
stallation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and the receiver.
•Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
•Consult the dealer or an experienced radio TV technician for help.
Notice:
1.The changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to oper-
ate the equipment.
2.Shielded interface cables must be used in order to comply with the
emission limits.

The G586SPA, equipped with a 321-pin Zero Insertion Force (ZIF) CPU
socket, is a fast system board supporting Intel Pentium CPUs running
at 75MHz, 90MHz, 100MHz, 120MHz, 133MHz, 150MHz and 166MHz
frequencies. The G586SPA also supports Cyrix P120+, P133+, P150+,
and P166+ CPUs.
The G586SPA can support 2MB to 256MB of system memory using
EDO or fast page mode x32 or x36 DRAM. This system board also
supports 256KB or 512KB pipeline burst, direct map write-back cache
installed on the system board
The G586SPA design is based on the Peripheral Component Intercon-
nect (PCI) and Industry Standard Architecture (ISA) standards. It is
equipped with 3 dedicated PCI slots, 3 dedicated 16-bit ISA slots and 1
shared PCI/ISA slot.
The G586SPA board has two bus master PCI IDE connectors. Bus
mastering reduces CPU use during disk transfer. This system board is
also equipped with two NS16C550A-compatible serial ports, an SPP/
ECP/EPP parallel port, a floppy disk drive controller, an IrDA header,
one PS/2 mouse port and one PS/2 or AT keyboard connector.

Chapter 2
Hardware Installation
This chapter summarizes the steps to install the G586SPA 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 memory chart on pages 14 and 15 for the number and type
of SIM 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 attract static electricity which can damage 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 G586SPA 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 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 G586SPA 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 nutdriver
1.Unlock your system unit. Turn off the power and disconnect all
power cords and cables.

11
2.Remove the system unit cover. Refer to the manufacturer’s instruc-
tions if necessary.
3.Remove expansion cards seated in any of the expansion slots and
detach all connectors from the old system board.
4.Loosen the screws holding the original system board and remove
the board from the system. Save the screws.
5.Remove the G586SPA 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 SIMMs into the SIMM banks on the G586SPA. The quan-
tity and location of the SIMMs depends on the memory configura-
tion 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 G586SPA system board into the case and re-
place the screws.
10.Reinstall all cards and connectors and replace the system unit
cover. Reconnect all power cords and cables.

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.
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.
System Memory
The G586SPA system board can support 2MB to 256MB of memory
using 72-pin SIMMs (Single In-line Memory Module). A SIM module
consists of several RAM chips soldered onto a small circuit board.
The SIM sockets are divided into two banks on the system board. Each
bank consists of 2 SIMM sockets. You will need 1 to 4 pieces of SIM
modules, depending on the amount of memory you intend to install.
The G586SPA system board uses 256KBx32/36, 512KBx32/36,
1MBx32/36, 2MBx32/36, 4MBx32/36, 8MBx32/36 and 16MBx32/36
SIMM modules. Refer to page 12 for the locations of the SIMM sockets.

Cache Memory
The G586SPA system board supports 256KB or 512KB pipeline burst,
direct map write-back cache installed at locations U21 and U22 of the
system board. Regardless of the amount of cache memory installed,
one 8KBx8, 16KBx8 or 32KBx8 is needed for tag RAM (U20) to store
the cacheable addresses. Refer to page 12 for the locations of the
SRAMs.
