Chapter 2
Hardware Installation
This chapter summarizes the steps to install the G586IPV 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. Please refer to 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 se-
lected 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 se-
lected the ideal location, unpack the G586IPV system board carefully.
Handling the System Board
It is quite easy to inadvertently damage your system board even before in-
stalling it in your system unit. Static electrical discharge can damage com-
puter 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 antistatic wrist strap and
attaching it to a metal part of the system chassis. If a wrist strap is unavail-
able, establish and maintain contact with the system chassis throughout any
procedures requiring ESD protection.
Installing the System Board
If you are installing the G586IPV 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

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 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 G586IPV from its original packing box. Be careful to avoid
touching all connectors and pins on the board. Please refer to the han-
dling instructions on pages 9-10 for proper handling techniques.
6.Insert the memory modules into the memory banks on the G586IPV. 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
G586IPV. Refer to the Cache Memory section on page 16 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 G586IPV system board into the case and replace the
screws.
11.Reinstall all cards and connectors and replace the system unit cover.

System Memory
The G586IPV system boards support two kinds of memory modules: DIMM
and SIMM. DIMM, which uses SDRAM, performs better than SIMM, which
uses DRAM.
DIMM
The DIMM (Dual In-line Memory Module) socket uses x64 EDO, FPM and
SDRAM. The G586IPV system board can support 8MB to 16MB memory us-
ing 1MBx64 or 2MBx64 168-pin DIMM. Refer to page 12 for the location of
the DIMM.
Installing the DIM Module
A DIM module simply snaps into a socket on the system board. Pin 1 of the
DIM module must correspond with Pin 1 of the socket.
1.Pull the "tabs" which are at the ends of the socket to the side.
2.Position the DIMM above the socket with the "notches" in the module
aligned with the "keys" on the socket.
3.Seat the module vertically into the socket. Make sure it is completely
seated. The tabs will hold the DIMM in place.

14
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 a bank first before going to the next bank.
The G586IPV system board can support 8MB to 128MB of memory using
1MBx32, 2MBx32, 4MBx32, or 8MBx32 72-pin SIMMs. The table below
shows the supported SIM modules and their corresponding memory sizes.
SIMMs

16MB
32MB
Examples:
If you are installing 8MB of memory, you must insert two 1MBx32 SIMMs in
Bank 0 or Bank 1. Inserting one 2MBx32 module will not work.
If you are installing 24MB of memory, you must insert two 1MBx32 SIMMs in
Bank 0 and two 2MBx32 SIMMs in Bank 1. You may also install it vice versa
by inserting two 1MBx32 SIMMs in Bank 1 and two 2MBx32 SIMMs in Bank
0.
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 completely
seated. Tilt the module upright until it locks in place in the socket.
Warning:
The DIMM and SIMM can not exist on the G586IPV system board at the
same time. You must only use either a DIMM or SIMMs on your system
board.

Cache Memory
The G586IPV system board can support 256KB or 512KB pipeline burst, di-
rect map write-back cache SRAM. Your system board may come with 256KB
or 512KB cache mounted onboard. The 160-pin cache module slot lets you
upgrade your cache memory by installing a 256KB cache module.
Note:
You do not need to set any jumpers or modify the Award BIOS Setup utility
when you install the cache module.
If your system board comes with 256KB cache at locations U22 and U23, you
can upgrade your cache memory to 512KB by installing a 256KB cache mod-
ule in the cache module slot. Please refer to page 12 for the locations of the
cache module slot (SSM1), U22 and U23.
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 mod-
ules other than those specified above.
Installing the Cache Module
Locate the 160-pin cache module slot on the system board (SSM1). Refer to
page 12 for the location of SSM1. Position the cache module above the slot.
Make sure pin 1 of the cache module is aligned with pin 1 of the slot. Care-
fully slide the module into the slot. Press firmly on the top of it to seat it
properly.

17
Note:
With the cache module installed in the cache module slot, the components on
the solder side of the add-in card in PCI Slot 3 must not protrude more than
5mm. The components of the component side of the add-in card in PCI Slot
2 also must not protrude more than 5mm.

18
CPU Installation
The G586IPV 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.
Please see the jumper settings on the following pages. Use the needle-nosed
plier to move the jumpers if necessary.
