Introduction
Introduction
The G586VPM/T system board offers several advanced features inte-
grated into the system board. It supports a 320-pin Zero Insertion Force
(ZIF) CPU socket for Intel Pentium™ 75/90/100/120/133/150/166/
200MHz CPUs Cyrix P120+/P133+/P150/P166+ CPUs and AMD K5
75/90MHz CPUs. The Cyrix CPUs support Linear burst mode, with
power supply supporting up to 10 ampere for CPU power consump-
tion. The ZIF socket allow users to easily upgrade their CPUs. The
G586VPM/T also supports Flash EPROM for easy BIOS upgrades.
Flash EPROM is a memory chip for the storage of BIOS which can
be erased in bulk or modified using a software utility.
Equipped with two built-in Bus Master PCI Enhanced IDE connectors,
the G586VPM/T system board can control four drives and supports
fast PIO Modes 3 and 4 Enhanced IDE hard drives. Bus mastering
reduces CPU use during disk transfer. The system board is also
equipped with two NS16C550A-compatible serial ports, an SPP/EPP/
ECP, a floppy disk drive controller, and one mini-DIN-6 connector for
the PS/2 mouse.
The G586VPM/T can be configured to many different memory sizes
ranging from 4MB to 512MB using 256KBx32/36, 512KBx32/36,
1MBx32/36, 2MBx32/36, 4MBx32/36, 8MBx32/36 or 16MBx32/36 non-

Chapter 2
Hardware Installation
This chapter summarizes the steps in installing the G586VPM/T sys-
tem 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 in-
stall. Please refer to the memory chart on pages 12 for the number
and type of SIM modules needed for the amount of memory you re-
quire.
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 G586VPM/T 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 components
facing up.
4.Hold the system board by its edges only. 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 G586VPM/T system board, the following out-
lines the basic installation instructions. 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-nose pliers
•One nut driver
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 in-
structions 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 G586VPM/T 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 G586VPM/T. The
quantity and location of the SIMMs is dependent upon 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
G586VPM/T.
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 G586VPM/T system board into the case and
replace the screws.
11.Reinstall all cards and connectors and replace the system unit
cover. Reconnect all power cords and cables.

System Memory
The G586VPM/T system board can support 4MB to 512MB 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 SIMM sockets are divided into four banks on the system board.
Each bank consists of 2 SIMM sockets. You can insert single-sided or
double-sided SIM modules to any of the banks located on the system
board.
The G586VPM/T system board uses 256KBx32/36, 512KBx32/36,
1MBx32/36, 2MBx32/36, 4MBx32/36, 8MBx32/36 and 16MBx32/36
SIM modules. Your system board can be configured with 4MB, 6MB,
8MB, 12MB, 16MB, 24MB, 32MB, 48MB, 64MB, 96MB, 128MB,

192MB, 256MB and other sizes up to 512MB of onboard memory.
Please refer to page 12 for the locations of the SIMM sockets.
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.
Memory Configuration
The G586VPM/T system board can support 8MB to 512MB of
memory using 1MBx32/36, 2MBx32/36, 4MBx32/36, 8MBx32/36,
or 16MBx32/36 72-pin SIMMs (Single In-line Memory Module). If
you are running a Cyrix CPU, install memory up to 2 Banks only
(4 pieces of SIMM Modules), which is up to 256MB. It is recom-
mended to put them in Bank 3 and/or Bank 2 when using a Cyrix
CPU.
Examples:
If you would like to install 8MB of memory, you may insert two
1MBx32/36 SIMMs in Bank 0 or Bank 1.
If you want to install 256MB of memory, you must insert four
16MBx32/36 SIMMs in bank 0 and bank1.

14
Cache Memory
The G586VPM/T provides a cache module slot rather than a built-in
cache. The system board can be configured to two different cache
sizes: 256KB (default), and 512KB. Insert the cache module into the
cache module slot. The system board is equipped with a 8Kx8 Tag
RAM mounted on location U6. Please refer to page 12 for the locations
of the cache module slot and U6.
256KB with 32-byte line size
512KB with 32-byte line size0-64MB 0-128MB
Cacheable Memory Range
If you are installing 24MB of memory, you may insert two 1MBx36
SIMMs in bank 0 and two 2MBx32/36 SIMMs in bank 1. You may
also install it vice versa by inserting the two 1MBx32/36 in bank 1
and the two 2MBx32/36 in Bank 0.
If you are using a Cyrix CPU, you may only use a 256KB cache module.

Installing Upgrade CPUs
The G586VPM/T is equipped with a 320-pin Zero Insertion Force
(ZIF) socket at location U5 of the system board. This socket is de-
signed for easy removal of an old CPU and easy insertion of an up-
grade 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.
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 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 20 minutes.
The 320-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 CPUs 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. A warning note — be
extremely careful to match pin 1 of the CPU with pin 1 of the socket.
Usually pin 1 of the CPU is marked by a dot or a cut corner.

19
Zero Insertion Force (ZIF) 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. The top plate will slide back. Do not use screw-
drivers or other tools to open the socket, or you may damage the
system or socket. 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.
Lifting the Handle

20
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.
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
