The G586VPS Pro design is based on the VLSI Lynx system controller
chipset. It is equipped with a 321-pin Zero Insertion Force (ZIF) CPU
socket to support various Intel®Pentium and Cyrix®6x86 CPUs.
The G586VPS Pro supports 8MB to 256MB of system memory using
EDO or fast page mode DRAM. It is equipped with 4 SIMM sockets
allowing you to install x32 or x36 SIMM. The x36 SIMM supports parity
checking which informs the user of memory failure and prevents error
accumulation. The system board also supports 256KB or 512KB fast
pipeline burst cache.
The G586VPS Pro system board has two PCI IDE connectors with bus
mastering capabilities that highly reduce 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 control-
ler, one PS/2 mouse port, one PS/2 or AT keyboard connector and one
IrDA connector for wireless connectivity between your computer and pe-
ripheral devices.

Chapter 2
Hardware Installation
This chapter summarizes the steps to install the G586VPS Pro 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. Refer
to the System Memory section for the 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 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 G586VPS Pro 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.

11
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 G586VPS Pro 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 nutdriver
1. Unlock your system unit. Turn off the power and disconnect all
power cords and cables.

12
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 of the expansion slots.
4. Loosen the screws holding the original system board and remove
the board from the system. Save the screws.
5. Remove the G586VPS Pro 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 10-11 for proper handling
techniques.
6. Insert the SIMMs into the SIMM banks on the system board. The
quantity and location of the SIMMs depends on the memory con-
figuration 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 G586VPS Pro system board into the case and
replace the screws.
10. Reinstall all cards and connectors and replace the system unit
cover. Reconnect all power cords and cables.

Examples:
If you are installing 8MB of memory, you must insert two 1MBx32/x36
SIMMs in Bank 0 or Bank 1. Inserting one 2MBx32/x36 module will not
work.
If you are installing 256MB of memory, you must insert four 16MBx32/
x36 SIMMs in Bank 0 and Bank 1.
If you are installing 24MB of memory, you must insert two 1MBx32/x36
SIMMs in Bank 0 and two 2MBx32/x36 SIMMs in Bank 1. You may also
install it vice versa by inserting two 1MBx32/x36 SIMMs in Bank 1 and
two 2MBx32/x36 SIMMs in Bank 0.
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 13 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. 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 G586VPS Pro system board can support 8MB to 256MB of
memory using 1MBx32/x36, 2MBx32/x36, 4MBx32/x36, 8MBx32/x36, or
16MBx32/x36 72-pin SIMMs. The table below shows the supported SIM
modules and their corresponding memory sizes.

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.

Installing Upgrade CPUs
The G586VPS Pro is equipped with a 321-pin Zero Insertion Force (ZIF)
socket at location U7 of the system board. Refer to page 13 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.
