Chapter 2
Hardware Installation
This chapter summarizes the steps to install the G586IPC 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
the memory chart on page 14 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 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 G586IPC 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 G586IPC 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
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 G586IPC 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 G586IPC. The quan-
tity and location of the SIMMs depends on the memory configura-
tion and type of modules you intend to use.
7.Insert the cache module, if any, into the cache module slot on the
G586IPC. Refer to the Cache Memory section on page 15 for up-
grading 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 G586IPC system board into the case and re-
place the screws.
11.Reinstall all cards and connectors and replace the system unit
cover. Reconnect all power cords and cables.

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.
You will need 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 any of the banks, Bank 0
or Bank 1, but you must populate a bank first before going to the next
bank.
The G586IPC system board can support 8MB to 256MB of memory us-
ing 1MBx36, 2MBx36, 4MBx36, 8MBx36, or 16MBx36 72-pin SIMMs.
The table below shows the supported SIM modules and their corre-
sponding memory sizes.

Examples:
If you are installing 8MB of memory, you must insert two 1MBx36
SIMMs in Bank 0 or Bank 1.
If you are installing 256MB of memory, you must insert four 16MBx36
SIMMs in Bank 0 and Bank 1.
If you are installing 24MB of memory, you must insert two 1MBx36
SIMMs in Bank 0 and two 2MBx36 SIMMs in Bank 1. You may also
install it vice versa by inserting two 1MBx36 SIMMs in Bank 1 and two
2MBx36 SIMMs in Bank 0.

14
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.

Cache Memory
The G586IPC system board can support 256KB or 512KB pipeline
burst, direct map write-back cache SRAM. Your system board may
come with 0KB or 256KB cache mounted onboard. The 160-pin cache
module slot lets you upgrade your cache memory by installing a 256KB
or 512KB 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 0KB cache, you can install a 256KB or
512KB cache module in the cache module slot. If your system board is
installed with 256KB onboard cache (located at U22 and U23), you can
upgrade your cache memory to 512KB by installing a 256KB cache
module in the cache module slot. Please refer to page 12 for the loca-
tions of the cache module slot (SSM1), U22 and U23.

Warning:
We highly recommend that you use T2BSM32-256 or T2BSM32-512
cache modules. Severe damage might occur on the cache module or
system board if you insert modules other than those specified above.
Installing the Cache Module
Locate the 160-pin cache module slot on the system board. Position the
cache module above the slot. Make sure pin 1 of the cache module is
aligned with pin 1 of the slot. Carefully slide the module into the slot.
Press firmly on the top of it to seat it properly.

16
Note:
With the cache module installed in the cache module slot, the compo-
nents on the solder side of the add-in card in PCI Slot 4 must not pro-
trude more than 5mm. There is no limit to the length of the add-in card
installed in PCI Slot 4.
CPU Installation
The G586IPC allows for easy installation of CPUs. Make sure all jump-
ers are set correctly before applying power or you may damage the

Installing Upgrade CPUs
The G586IPC is equipped with a 321-pin Zero Insertion Force (ZIF)
socket at location U27 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 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.

18
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.
Do not change any factory CPU speed jumper settings if you are install-
ing the 3.3V Pentium upgrade processor.
Before proceeding with the upgrade, take note of the following. The mi-
croprocessor and heat sink 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 heat sink cool for 10 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.
Warning:
Be extremely careful to match pin 1 of the CPU with pin 1 of the socket.
Only Intel's OverDrive processor is keyed to prevent improper place-
ment in the ZIF socket. Other Intel CPUs, as well as CPUs from other
vendors, can be placed incorrectly and will be permanently damaged if
incorrectly placed. Usually pin 1 of the CPU is marked by a dot or a cut
corner.
Zero Insertion Force (ZIF) Socket

19
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
amount of sideways force to free the handle from its retaining “tab.”
Once clear of the “tab,” the handle will open relatively easily. The
top plate will slide back. Do not use screwdrivers or other tools to
open the socket, or you may damage the system or socket.
Lifting the Handle
2.Once the lever is completely up, remove the old CPU carefully by
lifting it straight out of the socket. You are now ready to insert the
new CPU.

20
3.Position the CPU above the ZIF socket. Make sure pin 1 of the
CPU is aligned with pin 1 of the socket. Lower the chip until the
pins are inserted properly in their corresponding holes. Remember
that very little force is needed to install the CPU. If the CPU is not
easily inserted, verify whether or not pin 1 of the CPU is aligned
with pin 1 of the socket. Applying too much pressure can damage
the CPU or the socket.
Positioning the CPU Above the ZIF Socket
4.Push the handle down until the handle locks into place. The top
plate will slide forward. You will feel some resistance as the pres-
sure starts to secure the CPU in the socket. This is normal and will
not damage the CPU. However, if the handle is not completely
closed, damage to the CPU and/or system board may result.
Clearance Requirements
Your CPU comes with a heat sink mounted on top. To maintain proper
airflow once the upgrade is installed on the system board, the CPU and
heatsink require certain space clearances.
The clearance above the CPU’s fan/heat sink must be at least 0.4
inches. The clearance on at least 3 of 4 sides of the processor must be
at least 0.2 inches. The cables (for floppy drive, hard drive, CD-ROM,
etc.) must be routed clear of the CPU and its airspace.
