Chapter 2
Hardware Installation
This chapter summarizes the steps to install the G686IPA 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 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
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 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 selected the ideal location, unpack the G686IPA 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.
8
Page 9
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 unavailable, establish and maintain contact with the
system chassis throughout any procedures requiring ESD protection.
Installing the System Board
If you are installing the G686IPA 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
1. Unlock your system unit. Turn off the power and disconnect all
power cords and cables.
9
Page 10
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 G686IPA 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 8-9 for proper handling techniques.
6. Insert the memory modules into the memory banks on the
G686IPA. The quantity and location of the memory modules depends on the memory configuration 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 G686IPA 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. We recommend that
you plug the power cord into a properly grounded three-pronged
outlet.
Use only ATX or AT power connector. You cannot use both connectors at the same time. If you are using an ATX power supply, install
the 20-pin connector of the ATX power cable into location PL1 on
the system board. The 20-pin connector can be inserted into PL1
only if pin 1 of the connector is aligned with pin 1 of PL1.

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 either 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 either of the
banks, Bank 0 or Bank 1, but you must populate a bank first before
going to the next bank.
The G686IPA system board can support 8MB to 512MB of memory using 1MBx32/x36, 2MBx32/x36, 4MBx32/x36, 8MBx32/x36, 16MBx32/x36
or 32MBx32/x36 72-pin SIMMs. The table below shows the supported

Installing Upgrade CPUs
The G686IPA is equipped with a 387-pin Zero Insertion Force (ZIF)
socket at location U31 of the system board. Refer to page 11 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.
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 microprocessor 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 processor and heatsink cool for 10 minutes.
The 387-pin ZIF socket consists of 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.
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. It may be necessary to initially apply a small
16
Page 17
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.
Handle
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.
Pin 1
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.
17
Page 18
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.
Clearance Requirements
Your CPU comes with a heatsink 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/heatsink must be at least 0.4
inches. The clearance on at least 3 of 4 sides of the processor and
heatsink must be at least 0.2 inches. All 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 with heatsink. The temperature of the air entering the fan/heatsink cannot exceed 45oC (113oF).
The ambient or room temperature must be below 37oC (99oF).

Note:
An IDE cable with a standard 40-pin connector (without the keying
mechanism) 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.
Connecting the Hard Disk Cable
1. If you are connecting two hard drives, install the 40-pin connector
of the IDE cable into the primary IDE shrouded header (connector
J12). If you are adding a third or fourth IDE device, install the 40pin connector of the other IDE cable into the secondary IDE
shrouded header (connector J11).
2. Install the other 40-pin header connector(s) into the device with the
colored edge of the ribbon cable aligned with 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.
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.
We recommend that the Enhanced IDE hard drives be from the same
manufacturer. In a few cases, drives from two different manufacturers
will not function properly when used together. The problem lies in the
hard drives, not the G686IPA system board.

Page 24
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.
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. You may also
use the IDE HDD Auto Detection function which will allow the BIOS to
auto detect your hard drive type. Refer to the IDE HDD Auto Detection
section for details.
Warning:
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.
Universal Serial Bus Connectors
The G686IPA system board is equipped with two USB connectors on
locations J8 and J9 on the system board. USB allows data exchange
between your computer and a wide range of simultaneously accessible
peripherals.
Connecting the USB Ports
One optional card-edge bracket mounted with two USB port cables are
provided with the system board. Connect the upper USB port cable to
connector J8 and the lower USB port cable to connector J9 on the system board. Make sure the red wire of the USB cables is aligned with pin
1 of connectors J8 and J9. Mount the card-edge bracket to the system
chassis.
Note:
Make sure to enable “USB Controller” in the Integrated Peripherals
setup of the Award BIOS utility.

USB port cables (optional)
Installing Expansion Cards
The G686IPA system board is equipped with 3 dedicated PCI slots, 3
dedicated 16-bit ISA slots and 1 shared PCI/ISA slot. All PCI slots are
bus masters.
Refer to page 11 for the locations of the expansion slots.
Note:
The BIOS needs to be configured for the PCI add-in cards installed in
the PCI slots. Refer to the “PNP/PCI Configuration” presented in the
“Software Installation” section of the manual.

IRQ3 to IRQ15 (Wake Up Events in Doze and Standby, and
Power Down and Resume Events)
These are I/O events whose occurrence can prevent the system from
entering a power saving mode or can awaken the system from such a
mode. In effect, the system remains alert for anything which occurs to a
device which is configured as On, even when the system is in a power
saving mode.
When an I/O device wants to gain the attention of the operating system,
it signals this by causing an IRQ to occur. When the operating system
is ready to respond to the request, it interrupts itself and performs the
service. When set to On, the activity will neither prevent the system
from going into a power saving mode nor awaken it.
PNP/PCI Configuration
This section describes configuring the PCI bus system. PCI, or Peripheral Computer Interconnect, is a system which allows I/O devices to operate at speeds nearing the speed the CPU itself uses when communicating with its own special components. This section covers some very
technical items and it is strongly recommended that only experienced
users should make any changes to the default settings.

Hard Drive Mode
The G686IPA system board 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.
46
Page 47
Normal Mode
The Normal mode is the generic access mode in which neither the
BIOS nor the IDE controller will make any transformations during harddrive access.
The maximum number of cylinders, heads and sectors for Normal mode
are 1024, 16 and 63, respectively.
no. Cylinders (1024)
x no. Heads ( 16)
x no. Sectors ( 63)
x bytes per sector ( 512)
528 megabytes
If you set your HDD to Normal mode, the maximum accessible HDD will
be 528 megabytes even though the physical size of the HDD may be
greater than that.
LBA (Logical Block Addressing) Mode
The LBA mode is a 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 ( 255)
x no. Sectors ( 63)
x bytes per sector ( 512)
8.4 gigabytes
47
Page 48
Large Mode
The Large mode is the extended HDD access mode supported by the
system board. Some IDE HDDs have more than 1024 cylinders without
LBA support (in some cases, you may not want the LBA mode). This
system board provides another alternative to support these kinds of
HDDs.
The BIOS tells the operating system that the number of cylinders is half
of the actual number and that the number of heads is double the actual
number. During disk access, the reverse conversion is done by the
INT13h routine.
Example of Large mode:
CYLS. HEADS SECTORS MODE
1120 16 59 NORMAL
560 32 59 LARGE
Maximum HDD size:
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.

HDD Low Level Format
The Low Level Format utility is designed as a tool to save you time
formatting your hard disk. It automatically looks for the necessary information of the drive you selected. This utility also searches for bad
tracks and lists them for your reference. Highlight this option and press
<Enter>. A screen similar to the one below will appear.
Save & Exit Setup
When all the changes have been made, highlight “Save & Exit Setup”
and press <Enter>. The message below will appear:
Save to CMOS and Exit (Y/N)? N
Type “Y” and press <Enter>. The following message will appear:
Reboot System (Y/N)? N
Type “Y” and press <Enter>. The modifications you have made will be
written into the CMOS memory, and the system will reboot. You will
once again see the initial diagnostics on the screen. If you wish to
make additional changes to the setup, press <Ctrl> <Alt> <Esc> simultaneously or <Del> after memory testing is done.
49
Page 50
Exit Without Saving
When you do not want to save the changes you have made, highlight “Exit
Without Saving” and press <Enter>. The message below will appear:
Quit Without Saving (Y/N)? N
Type “Y” and press <Enter>. The system will reboot and you will once
again see the initial diagnostics on the screen. If you wish to make any
changes to the setup, press <Ctrl> <Alt> <Esc> simultaneously or
<Del> after memory testing is done.
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 the message PRESS
F1 TO CONTINUE, CTRL-ALT-ESC or DEL TO ENTER SETUP, will be
shown in the information box at the bottom. Enter Setup to correct the
error.
POST Beep
Currently there are two kind of beep codes in BIOS. The one code
indicates that a video error has occured and the BIOS cannot initialize
the video screen to display any additional information. This beep code
consists of a signle long beep followed by three short beeps. The other
one code indicates that your DRAM error has occured. This beep code
consists of a signle long beep repeatedly.
Error Messages
One or more of the following messages may be displayed if the BIOS
detects an error during the POST. This list indicates the error messages
for all Awards BIOSes:
