v Introduction
The G586OPC/E system board offers several advanced
features integrated into the system board. Its design is
based on the new Peripheral Component Interconnect
(PCI) local bus and Industry Standard Architecture
(ISA) standards.
The G586OPC provides a 321-pin Zero Insertion Force
(ZIF) CPU socket for PentiumTM processors running at
75MHz, 90MHz, 100MHz, 120MHz, 133MHz or
150MHz frequency. This ZIF socket allows users to
easily upgrade their CPUs. It also provides a VRM
(Voltage Regulation Module) header allowing you to
upgrade to future low-voltage CPUs.
The G586OPC/E is equipped with three PCI slots, three
ISA slots and one shared PCI/ISA slot.
The G586OPC/E board has two bus master PCI IDE
connectors. Bus mastering reduces CPU use during disk
transfer. The system board is also equipped with two
NS16C550A-compatible serial ports, an SPP/EPP/ECP
parallel port, a floppy disk drive controller, one PS/2
mouse port and one PS/2 keyboard connector.
G586OPC/E
The G586OPC/E can support 2MB to 128MB of
memory using 256Kx36, 512Kx36, 1Mx36, 2Mx36,
4Mx36 and 8Mx36 72-pin SIM modules.

v Installation Overview
This chapter summarizes the steps in installing the
G586OPC 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 pages 8
and 9, 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 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 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 selected the
6
Page 15
ideal location, unpack the G586OPC system board
carefully.
Handling the System Board
It is quite easy to inadvertently damage your system
board even before installing it to 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.
Tips in Handling the System Board
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 wriststrap.
3. Do all preparation work on a static-free surface with
components facing up.
G586OPC/E
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 upgrade
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
7
Page 16
PCI/ISA System Board
ESD protection by wearing an antistatic 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.
Hardware Installation
Memory Installation
The G586OPC system board can support 2MB to
128MB of memory using 72-pin SIMMs (Single In-Line
Memory Module).
The SIMM sockets are divided into two banks on the
system board. The G586OPC system board uses
256Kx36, 512Kx36, 1Mx36, 2Mx36, 4Mx36 and
8Mx36 SIMMs. Non-parity (x32) SIMMs can also be
used if parity checking is turned off in CMOS setup.
You will need 2 or 4 pieces of SIMMs, depending on
the amount of memory you intend to install.
To install the SIM modules, first populate Bank 0 and
then Bank 1, or the system will not work.
The table on the next page summarizes the bank locations and modules needed for the corresponding memory
sizes. Each bank consists of 2 SIMM sockets.

Installing the Modules
A SIMM simply snaps into a socket on the system
board. Pin 1 of the SIMM 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 45o angle into the bank. Make
sure it is completely seated. Tilt the module upright
until it locks in place in the socket.

Cache Configuration
The G586OPC system board can support either asynchronous cache SRAM or synchronous (pipelined
burst) cache SRAM. Three cache sizes are supported:
256KB, 512KB and 1MB. 256KB is the default size.
Installing Asynchronous Cache SRAM
The SRAM sockets allow you to install either 32Kx8,
64Kx8 or 128Kx8 SRAM. Regardless of the amount of
cache memory installed, one 32Kx8 (U23) is needed for
tag RAM to store the cacheable addresses. The locations
of the SRAM sockets on the system board are shown on
the next page.
Note
Use only the 5V/3.3V mixed-voltage or pure 3.3V Data
SRAM chips if you are changing or upgrading the
asynchronous cache RAM of your system board. DO
NOT install the regular 5V cache chips in the Data
SRAM sockets; otherwise problems will occur because
they are not compatible. Regardless of the type of Data
SRAM used, install only 5V Tag SRAM on your system
board.

PCI/ISA System Board
Installing Upgrade CPUs
The G586OPC is equipped with a 321-pin Zero
Insertion Force (ZIF) socket at location U26 of the
system board. This socket is designed for easy removal
of the old CPU and easy insertion of the 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, the installation is being done incorrectly.
Warning:
Open the socket only if 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.
You do not need to change any jumpers to properly
install the 3.3V Pentium Upgrade Processor.
Before proceeding with the upgrade, take note of the
following. The microprocessor 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.
42
The 321-pin ZIF socket consists of the four rows of pin
holes on each side. To prevent improper OverDrive
Processor installation, the ZIF socket has a Plug/Keying
mechanism. Several holes in the socket are plugged so
OverDrive Processors will go in only one way. If you
cannot easily insert the OverDrive Processor, 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. Only Intel's
OverDrive Processor is keyed to prevent improper
placement in the ZIF socket. Other Intel CPUs, as well
Page 51
G586OPC/E
as CPUs from other vendors, can be placed incorrectly
and will be permanently damaged.
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 down, pull it out to
the side a little and raise it as far as it will go. The
top plate will slide back. Do not use screwdrivers or
other tools to open the socket, or damage may occur
to 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.
43
Page 52
PCI/ISA System Board
2. Once the lever is completely up, remove the old
CPU by carefully lifting it straight out of the socket.
You are now ready to insert the new CPU.
Lifting the Handle
44
Pin 1 of the ZIF Socket
Page 53
G586OPC/E
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 will
not insert easily, verify 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 pressure 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.

PCI/ISA System Board
Clearance Requirements
The 3.3V Pentium Upgrade Processor comes with a heat
sink mounted on top. To maintain proper airflow once
the upgrade is installed on the system board, the
processor and sink require certain space clearances.
The clearance above 3.3V Pentium Upgrade Processor's
fan/heat-sink must be at least 0.4 in. The clearance on at
least 3 of 4 sides of the processor must be at least 0.2
in. The cables (for floppy drive, hard drive, CD-ROM,
etc.) must be routed clear of the CPU and its airspace.
Fan Exhaust
The CPU must be kept cool by using a fan exhaust
configuration in connection with the heatsink. The
temperature of the air entering the fan/heatsink cannot
exceed 45°C. The ambient or room temperature must be
below 37°C (99°F) for a system installed with the 3.3V
Pentium Upgrade Processor.
46
In order to provide proper airflow to the CPU, all
movable obstructions (power supply cables, cards,
floppy disk cables) must be clear of the CPU heatsink/
fan component in accordance with the space clearance
discussed in the CPU installation section of this manual.

Connecting the Serial Ports
Two DB-9P serial port cables are provided with the
motherboard. They are mounted on a card-edge bracket
along with the PS/2 mouse cable. The upper serial port
cable should be used for the COM 1 primary serial port;
connect it to Connector COM 1 on the motherboard.
The lower serial port cable should be used for the COM
2 secondary serial port; connect it to Connector COM 2
on the motherboard. Make sure the colored stripes on
the ribbon cables align with pin 1 of Connectors COM 1
and COM 2. Mount the card-edge bracket to the system
chassis.

52
Step 1
Install the 34-pin header connector into the floppy disk
connector (J8) on the system board. The colored edge of
the ribbon should be aligned to pin 1 of the J8 connector.
Step 2
Install the other 34-pin header connector(s) into the disk
drive(s) with the colored edge of the daisy chained
ribbon cable aligned to pin 1 of the drive edge
connector(s). The end-most connector should be attached to the drive you want to be Drive A.
Page 61
IDE Hard Disk Interface
The G586OPC system board is equipped with two PCI
IDE shrouded headers that will interface four IDE
(Integrated Drive Electronics) hard disk drives.
Note:
Only IDE drives can be connected to the IDE interface.
Connecting the IDE Hard Disk Interface
To prevent improper IDE cable installation, each PCI
IDE shrouded header has a keying mechanism. The 40pin connector on the IDE cable can be placed into the
header only if pin 1 of the connector is aligned with pin
1 of the header.
G586OPC/E
Note:
The IDE cable with a standard 40-pin connector can be
installed in the PCI IDE shrouded header. Be extremely
careful to match the colored edge of the ribbon with pin
1 of the header.
53
Page 62
PCI/ISA System Board
The IDE Hard Disk Connector on the System Board
Step 1
If you are connecting two hard drives, install the 40-pin
connector of the IDE cable into the primary IDE
shrouded header (1st IDE Connector). If you are adding
a third or fourth IDE device, install the 40-pin connector
of the other IDE cable into the secondary IDE shrouded
header (2nd IDE Connector).
54
Step 2
Install the other 40-pin header connector(s) into the
device with the colored edge of the ribbon cable aligned
to pin 1 of the drive edge connector(s).
Note:
Refer to your disk drive user's manual for information
about selecting proper drive switch settings.
Page 63
Adding a Second IDE Hard Drive
When using two IDE drives, one must be set as the
master and the other as the slave. Follow the instructions provided by the drive manufacturer for setting the
jumpers and/or switches on the drives. No changes are
needed on the G586OPC system board when adding a
second hard drive.
We recommend that the IDE hard drives be from the
same manufacturer. In a few cases, drives from two
manufacturers will not function properly when used
together. The problem lies in the hard drives, not the
G586OPC system board.
Preparing an IDE Drive for Use
IDE disk drives are already low-level formatted, with
any bad-track errors entered, when shipped by the drive
manufacturer. Do not attempt to do a low-level format,
or you may cause serious damage to the drive.
G586OPC/E
To use an IDE drive, you need to enter the drive type
(this information is provided by the drive manufacturer)
into the system’s CMOS setup table. Then run FDISK
and FORMAT provided with DOS.
Note:
Do not run FDISK and FORMAT programs on a drive
that has already been formatted, or you will lose all
programs and data stored on the drive.

PCI/ISA System Board
Installing Expansion Cards
The G586OPC is equipped with three dedicated PCI and
three dedicated ISA slots. One PCI slot and one ISA slot
are shared. You can only install a card in one or the
other of the shared slots at a time; you cannot install
devices in both slots. Due to the size of the the optional
synchronous pipeline burst cache module installed in the
160-pin cache module upgrade slot, the length of the
card in PCI Slot 2 is limited. Refer to page 27 for limitations. The locations of the expansion slots are shown on
the next page.
Note:
The BIOS needs to be configured for the PCI add-on
cards installed in the PCI slots. Refer to the “PCI
Configuration Setup” chapter presented in the “Initial
Setup Program” section of the manual.

Hard Drive Mode
The G586OPC supports three HDD modes: Normal,
LBA and Large. If your hard disk drive does not support
LBA mode, the “LBA” option will not be displayed. If
your HDD has 1024 or fewer cylinders, the “Large”
option will not be displayed.
72
Normal Mode
The Normal mode is the generic access mode in which
neither the BIOS nor the IDE controller will make any
transformations during hard-drive access.
The maximum number of cylinders, heads and sectors
for Normal mode are 1024, 16 and 63, respectively.
Page 81
G586OPC/E
no. Cylinders (1024)
x no. Heads ( 16)
x no. Sectors ( 63)
x bytes per sector ( 512)
528 Megabyte
If you set your HDD to Normal mode, the maximum
accessible HDD size will be 528 Megabytes even
though its physical size may be greater than that.
LBA (Logical Block Addressing) Mode
The LBA mode is a new HDD accessing method to
overcome the 528 Megabyte limitation. The number of
cylinders, heads and sectors shown on the screen may
not be the actual number for the HDD.
During the HDD accessing, the IDE controller will
transform the logical address described by the sector,
head and cylinder number into its own physical address
inside the HDD.
The maximum HDD size supported by the LBA mode is
8.4 Gigabytes. It is obtained by the following formula.
no. Cylinders (1024)
x no. Heads ( 225)
x no. Sectors ( 63)
x bytes per sector ( 512)
8.4 Gigabyte
73
Page 82
PCI/ISA System Board
Large Mode
The Large mode is the extended HDD access mode
supported by the G586OPC system board. Some IDE
HDDs have more than 1024 cylinders without LBA
support (in some cases, you may not want the LBA
mode). The system board provides another alternative to
support these kinds of HDD.
The BIOS tells the operating system that the number of
cylinders is 1/2 of actual and that the number of heads is
double the actual. During the disk access, the reverse
conversion is done by the INT13h routine.
Example of Large mode:
Maximum HDD size:
CYLS. HEADS SECTORS MODE
1120 16 59 NORMAL
560 32 59 LARGE
74
no. Cylinders (1024)
x no. Heads ( 32)
x no. Sectors ( 63)
x bytes per sector ( 512)
1 Gigabyte
Note:
To support LBA or Large mode, address translation
software is included in the Award BIOS HDD Sevice
Routine (INT13h). If you are running an operating
system that bypasses the BIOS Int13 Service Routine,
LBA and Large Mode may fail.

v Appendix D: System Error Report
When the BIOS encounters an error that requires the
user to correct something, either a beep code will sound
or a message will be displayed in a box in the middle of
the screen and a message PRESS F1 TO CONTINUE,
CTRL-ALT-ESC or DEL TO ENTER SETUP will be
shown in the information box at the bottom.
POST Beep
There is one beep code in BIOS. This code indicates
that a video error has occurred and the BIOS cannot
initialize the video screen to display any additional
information. This beep code consists of a single long
beep followed by two short beeps.
Error Messages
One or more of the following messages may be displayed if the BIOS detects an error during the POST.
G586OPC/E
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS
ENTER
No boot device was found. Insert a system disk into
Drive A and press <Enter>. If the system normally boots
from the hard drive, make sure the controller is inserted
correctly and all cables are properly attached. Also be
sure the disk is formatted as a boot device. Then reboot
the system.
DISKETTE DRIVES OR TYPES MISMATCH ERROR - RUN
SETUP
Type of diskette drive installed in the system is different
from the CMOS definition. Run setup to reconfigure the
drive type correctly
89
Page 98
PCI/ISA System Board
DISPLAY SWITCH IS SET INCORRECTLY
The display switch on the motherboard can be set to
either monochrome or color. This indicates the switch is
set to a different setting than indicated in Setup. Determine which setting is correct, and then either turn off
the system and change the jumper, or enter Setup and
change the VIDEO selection.
DISPLAY TYPE HAS CHANGED SINCE LAST BOOT
Since last powering off the system, the display adapter
has been changed. You must configure the system for
the new display type.
ERROR ENCOUNTERED INITIALIZING HARD DRIVE
Hard drive cannot be initialized. Be sure the adapter is
installed correctly and all cables are correctly and firmly
attached. Also, be sure the correct hard drive type is
selected in Setup (refer to page 22).
ERROR INITIALIZING HARD DISK CONTROLLER
Cannot initialize controller. Make sure the card is
correctly and firmly installed in the bus. Be sure the
correct hard drive type is selected in Setup. Also, check
to see if any jumper needs to be set correctly on the
hard drive.
90
FLOPPY DISK CNTRLR ERROR OR NO CNTRLR
PRESENT
Cannot find or initialize the floppy drive controller.
Make sure the controller is installed correctly and
firmly. If no floppy drive is installed, be sure the Diskette Drive selection in Setup is set to NONE.
Page 99
G586OPC/E
KEYBOARD ERROR OR NO KEYBOARD PRESENT
Cannot initialize the keyboard. Make sure the keyboard
is attached correctly and no keys are being pressed
during the boot.
If you are purposely configuring the system without a
keyboard, set the error halt condition in Setup to HALT
ON ALL, BUT KEYBOARD. This will cause the BIOS
to ignore the missing keyboard and continue the boot.
MEMORY ADDRESS ERROR AT...
Indicates a memory address error at a specific location.
You can use this location along with the memory map
for your system to find and replace the bad memory
chips.
MEMORY PARITY ERROR AT...
Indicates a memory parity error at a specific location.
You can use this location along with the memory map
for your system to find and replace the bad memory
chips.
MEMORY SIZE HAS CHANGED SINCE LAST BOOT
Memory has been added or removed since the last boot.
Enter Setup and enter the new memory size in the
memory fields.
MEMORY VERIFY ERROR AT...
Indicates an error verifying a value already written to
memory. Use the location along with your system’s
memory map to locate the bad chip.
OFFENDING ADDRESS NOT FOUND
This message is used in conjunction with the I/O
CHANNEL CHECK and RAM PARITY ERROR
messages when the segment that has caused the problem
cannot be isolated.
91
Page 100
PCI/ISA System Board
OFFENDING SEGMENT
This message is used in conjunction with the I/O
CHANNEL CHECK and RAM PARITY ERROR
messages when the segment that has caused the problem
has been isolated.
PRESS A KEY TO REBOOT
This will be displayed at the bottom screen when an
error occurs that requires a reboot. Press any key and the
system will reboot.
PRESS F1 TO DISABLE NMI, F2 TO REBOOT
When BIOS detects a Non-Maskable Interrupt condition
during boot, this will allow NMI to be disabled and
continue to boot. You can also reboot the system with
the NMI enabled.
RAM PARITY ERROR - CHECKING FOR SEGMENT
Indicates a parity error in Random Access Memory.
SYSTEM HALTED, (CTRL-ALT-DEL) TO REBOOT...
Indicates the present boot attempt has been aborted and
the system must be rebooted. Press and hold down the
CTRL and ALT keys and press DEL simultaneously.
