C586VXG System Board User’s Manual
This chapter summarizes the steps to install the C586VXG 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. Refer to the System Memory section 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, threepronged 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 C586VXG
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.
Static Electricity Precautions
1. To prevent electrostatic build-up, leave the board in its anti-static
bag until you are ready to install it.
12
Page 13
Hardware Installation
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.

System Memory
The C586VXG system board supports two kinds of memory
modules: DIMM and SIMM. DIMM, which sometimes uses SDRAM,
performs better than SIMM, which uses DRAM. When you are
purchasing DIMMs, please specify you want the Intel compatible type.
(There are DIMMs made for other types of computers that are not
compatible.)
Note:
DIM and SIM modules cannot exist on the C586VXG system
board at the same time. Use either SIMM or DIMM only. Make
sure JP5 is set according to the type of memory module
installed on the system board.
DIMM
The two 168-pin DIMM
(Dual In-line Memory
Module) sockets use x64
EDO, FPM and SDRAM.
The system board can
support 8MB to 128MB
memory.

Cache Memory
The C586VXG system board
supports 256KB or 512KB
pipeline burst, direct map writeback cache installed at locations
U18 and U22 of the system
board. One SRAM is mounted
on location U23 for tag SRAM
to store the cacheable
addresses.
Processor Upgrade Information
Your system board allows for
easy installation of processors.
Make sure all jumpers are set
correctly before applying
power or you may damage the
processor or system board.
Use a needle-nosed plier to
move the jumpers if necessary.
Jumper JP1’s pins 1-6 are used
to set the external bus clock of
your processor. The clock
generator will determine the external bus clock that must be sent
to the processor through these settings.
Jumper JP1’s pins 7-12 are used to set the frequency ratio of your
processor.
After setting these jumpers, an Intel processor will multiply the
external bus clock by the frequency ratio to become the internal
clock speed. Internal clock speed is the commonly known speed of
22
Page 23
Hardware Installation
Intel processors in the market and is the actual operating clock of
the processor (external bus clock x frequency ratio = internal
clock speed).
Cyrix and AMD processors use the PR-rating system which is the
overall processor performance rating.
Jumpers JP2-JP4 are used to set the voltage of your processor.
Make sure these jumpers are set correctly, otherwise your system
will hang.

Hardware Installation
Installing Upgrade Processors
The C586VXG is equipped with a 321-pin Zero Insertion Force
(ZIF) socket at location U24 of the system board. This socket is
designed for easy removal of an old processor and easy insertion
of an upgrade processor. The ZIF socket allows you to carefully
place the new processor into its position. If you need to apply
excessive force to insert the processor, you are not installing the
processor correctly.
Warning:
Open the socket only if you are actually installing a processor.
The warranty on the original processor 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 20 minutes.
The 321-pin ZIF socket consists of five rows of pin holes on each
side. To prevent improper processor installation, the ZIF socket has a
Plug/Keying mechanism. Several holes in the socket are plugged so
that the processor will go in only one way. If you cannot easily insert
the processor, verify that pin 1 of the processor is aligned with pin 1
of the socket. Also verify that all the pins are straight, and not bent
nor broken.

C586VXG System Board User’s Manual
To install an upgrade processor, 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.
Handle
Lifting the Handle
2. Once the lever is completely up, remove the old processor
carefully by lifting it straight out of the socket. You are now ready
to insert the new processor.
Pin 1

Page 29
Hardware Installation
3. Position the processor above the ZIF socket. Make sure pin 1 of
the processor is aligned with pin 1 of the socket. Lower the
processor until the pins are inserted properly in their
corresponding holes. Remember that very little force is needed to
install the processor. If the processor is not easily inserted, verify
whether or not pin 1 of the processor is aligned with pin 1 of
the socket. Applying too much pressure can damage the
processor or the socket.
Pin 1
Positioning the Processor 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 pressure
starts to secure the processor in the socket. This is normal and
will not damage the processor. However, if the handle is not
completely closed, damage to the processor and/or system
board may result.

C586VXG System Board User’s Manual
Installing A Fan/Heatsink
Position the fan/heatsink on the processor such that the air from the
side of the fan/heatsink will flow across the heat regulators on the
system board. See the figure below.
Clearance Requirements
Your processor comes with a heatsink mounted on top. To maintain
proper airflow once the upgrade is installed on the system board,
the processor and heatsink require certain space clearances. The
clearance above the processor’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 processor and its
airspace.
Fan Exhaust
The processor 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).

ribbon cable with pin 1 of the drive edge connector(s). The endmost connector should be attached to the drive you want to
designate as Drive A.
IDE Hard Disk Interface
The C586VXG system board is equipped with two shrouded PCI
IDE headers that will interface four Enhanced IDE (Integrated Drive
Electronics) hard disk drives.
Connecting the IDE Hard Disk Interface
To prevent improper IDE cable installation, each shrouded PCI IDE
header has a keying mechanism. The 40-pin connector on the IDE
cable can be placed into the header only if pin 1 of the connector is

Note:
An IDE cable with a standard 40-pin connector (without the
keying mechanism) can be installed in the shrouded IDE
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 shrouded
IDE header (connector J12).
If you are adding a third or
fourth IDE device, install the
40-pin connector of the
other IDE cable into the
secondary shrouded IDE
header (connector J13).
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).
2
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 you use Enhanced IDE or ATA-2 and ATA-3
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
C586VXG system board.
37
Page 38
2
C586VXG System Board User’s Manual
Important:
If you encountered problems while using an ATAPI CD-ROM
drive that is set in Master mode, please set the CD-ROM drive
to Slave mode. Some ATAPI CD-ROMs may not be recognized
and cannot be used if incorrectly set in Master mode.
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
your operating system. 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 Chapter 3 - 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.

error; it will stop for all other errors.
All, But Diskette The system boot will not stop for a disk error;
it will stop for all other errors.
All, But Disk/Key The system boot will not stop for a disk or
keyboard error; it will stop for all other errors.
Memory
The base memory size, extended memory size and the other memory
size cannot be altered; your computer automatically detects and displays
them.
Base Memory The POST will determine the amount of base (or
conventional) memory installed in the system. The
value of the base memory is typically 512K for
systems with 512K memory installed on the
motherboard or 640K for systems with 640K or
more memory installed on the motherboard.
48
Extended Memory The BIOS determines how much extended
memory is present during the POST. This is the
amount of memory located above 1MB in the
CPU’s memory address map.
Other Memory This refers to the memory located in the 640K to
1024K address space. This is the memory that can
be used for different applications. DOS uses this
area to load device drivers in an effort to keep as
much base memory free for application programs.
The BIOS is the most frequent user of this RAM
area since this is where it shadows the ROM.

Virus Warning
This category protects the boot sector and partition table of your hard
disk drive. When this item is enabled, the Award BIOS will monitor the
boot sector and partition table of the hard disk drive. If an attempt
is made to write to the boot sector or partition table of the hard disk
drive, the BIOS will halt the system and an error message will appear.
After seeing the error message, if necessary, you will be able to run
an anti-virus program to locate and remove the problem before any
damage is done.
Many disk diagnostic programs which attempt to access the boot
sector table will cause the warning message to appear. If you are
running such a program, we recommend that you first disable this
category. Also, disable this category if you are installing or running
certain operating systems like Windows® 95 or the operating system
may not install nor work.

This entry allows you to select how gate A20 is handled. Gate A20
is a device used to address memory above 1 Mbyte. Initially, gate A20
was handled via a pin on the keyboard. Today, while keyboards still
provide this support, it is more common, and much faster, for the
system chipset to provide support for gate A20.
Typematic Rate Setting
When disabled, continually holding down a key on your keyboard will
cause the BIOS to report that the key is down. When the typematic
rate is enabled, the BIOS will not only report that the key is down,
but will first wait for a moment, and, if the key is still down, it will begin
to report that the key has been depressed repeatedly. For example,
you would use such a feature to accelerate cursor movements with
the arrow keys.

Typematic Rate (Chars/Sec)
This selection allows you to select the rate at which the keys are
accelerated.
Typematic Delay (Msec)
This selection allows you to select the delay between when the key
was first depressed and when the acceleration begins.

IDE Primary Master/Slave PIO and IDE Secondary Master/Slave PIO
PIO means Programmed Input/Output. Rather than have the BIOS
issue a series of commands to effect a transfer to or from the disk
drive, PIO allows the BIOS to tell the controller what it wants and
then let the controller and the CPU perform the complete task by
themselves. Your system supports five modes, 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select the
best available mode after checking your drive.
Auto The BIOS will automatically set the system according to your
hard disk drive’s timing.

Desktop Management Interface (DMI)
Your system board comes with a DMI built into the BIOS. DMI,
along with the appropriately networked software, is designed to
make inventory, maintenance and troubleshooting of computer
systems easier. With DMI, a network administrator or MIS engineer
can remotely access some information about a particular computer
system without physically going to it. Quite often a service call may
be unnecessary as the problem can be solved remotely.
The DMI utility in the BIOS automatically records various information
about your system configuration. Information about the type and speed
of CPU, type and amount of memory for each memory slot, BIOS
revision level, types of add-in PCI boards and components, certain
revision numbers of hardware installed, etc. are automatically detected
and stored in the DMI pool, which is a part of the system board's
Plug and Play BIOS. Additional information, such as ISA based
peripherals, which may not be automatically detected, can be manually
recorded in the DMI pool by using the Add DMI menu. The DMI pool
data is then verified or updated whenever the system hardware or
setup is altered.
4
Running the DMI Utility
To run the DMI utility, type: DMICFG.EXE.
The DMI utility must run in real mode with at least 180K of base
memory. Memory managers like HIMEM.SYS (required by Windows)
must not be installed. You may do this by using one of the 3 methods
listed below.
1. Boot up from a system diskette without the AUTOEXEC.BAT and
CONFIG.SYS files,
2. “REM” HIMEM.SYS in the CONFIG.SYS, or
3. Press <F5> during bootup to bypass your AUTOEXEC.BAT and
CONFIG.SYS files.

C586VXG System Board User’s Manual
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
There are two kinds of beep codes in the BIOS. 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 single long beep followed by three short
beeps. The other code indicates that a DRAM error has occured.
This beep code consists of a single long beep.
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:
CMOS BATTERY HAS FAILED

Caution:
Danger of explosion if battery incorrectly replaced. Replace only
with the same or equivalent type recommended by the
manufacturer. Dispose of used batteries according to the battery
manufacturer’s instructions.
CMOS CHECKSUM ERROR
Checksum of CMOS is incorrect. This can indicate that CMOS has
become corrupt. This error may have been caused by a weak
battery. Check the battery and replace if necessary.
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,
either turn off the system and change the jumper or enter Setup
and change the VIDEO selection.

Troubleshooting Checklist
This chapter of the manual is designed to help you with problems
that you may encounter with your personal computer. To efficiently
troubleshoot your system, treat each problem individually. This is to
ensure an accurate diagnosis of the problem in case a problem has
multiple causes.
Some of the most common things to check when you encounter
problems while using your system are listed below.
1. The power switch of each peripheral device is turned on.
2. All cables and power cords are tightly connected.
3. The electrical outlet to which your peripheral devices are
connected is working. Test the outlet by plugging in a lamp or
other electrical device.
4. The monitor is turned on.
5. The display’s brightness and contrast controls are adjusted
properly.
D
6. All add-in boards in the expansion slots are seated securely.
7. Any add-in board you have installed is designed for your system
and is set up correctly.
Monitor/Display
If the display screen remains dark after the system is turned on:
1. Make sure that the monitor’s power switch is on.
2. Check that one end of the monitor’s power cord is properly
attached to the monitor and the other end is plugged into a
working AC outlet. If necessary, try another outlet.
3. Check that the video input cable is properly attached to the
monitor and the system’s display adapter.
4. Adjust the brightness of the display by turning the monitor’s
brightness control knob.

The picture seems to be constantly moving.
1. The monitor has lost its vertical sync. Adjust the monitor’s
vertical sync.
2. Move away any objects, such as another monitor or fan, that
may be creating a magnetic field around the display.
3. Make sure your video card’s output frequencies are supported
by this monitor.
The screen seems to be constantly wavering.
1. If the monitor is close to another monitor, the adjacent monitor
may need to be turned off. Fluorescent lights adjacent to the
monitor may also cause screen wavering.
Power Supply
When the computer is turned on, nothing happens.
1. Check that one end of the AC power cord is plugged into a live
outlet and the other end properly plugged into the back of the
system.
2. Make sure that the voltage selection switch on the back panel is
set for the correct type of voltage you are using.
3. The power cord may have a “short” or “open”. Inspect the cord
and install a new one if necessary.
Floppy Drive
The computer cannot access the floppy drive.
1. The floppy diskette may not be formatted. Format the diskette
and try again.
2. The diskette may be write-protected. Use a diskette that is not
write-protected.
3. You may be writing to the wrong drive. Check the path
statement to make sure you are writing to the targeted drive.
80

Troubleshooting
4. There is not enough space left on the diskette. Use another
diskette with adequate storage space.
Hard Drive
Hard disk failure.
1. Make sure the correct drive type for the hard disk drive has
been entered in the BIOS.
2. If the system is configured with two hard drives, make sure the
bootable (first) hard drive is configured as Master and the
second hard drive is configured as Slave. The master hard drive
must have an active/bootable partition.
Excessively long formatting period.
1. If your hard drive takes an excessively long period of time to
format, it is likely a cable connection problem. However, if your
hard drive has a large capacity, it will take a longer time to
format.
Parallel Port
D
The parallel printer doesn’t respond when you try to print.
1. Make sure that your printer is turned on and that the printer is
on-line.
2. Make sure your software is configured for the right type of
printer attached.
3. Verify that the onboard LPT port’s I/O address and IRQ settings
are configured correctly.
4. Verify that the attached device works by attaching it to a parallel
port that is working and configured correctly. If it works, the
printer can be assumed to be in good condition. If the printer
remains inoperative, replace the printer cable and try again.

Serial Port
The serial device (modem, printer) doesn’t output anything or is
outputting garbled characters.
1. Make sure that the serial device’s power is turned on and that
the device is on-line.
2. Verify that the device is plugged into the correct serial port on
the rear of the computer.
3. Verify that the attached serial device works by attaching it to a
serial port that is working and configured correctly. If the serial
device does not work, either the cable or the serial device has a
problem. If the serial device works, the problem may be due to
the onboard I/O or the address setting.
4. Make sure the COM settings and I/O address are configured
correctly.
Keyboard
Nothing happens when a key on the keyboard was pressed.
1. Make sure the keyboard is properly connected.
2. Make sure there are no objects resting on the keyboard and
that no keys are pressed during the booting process.
System Board
1. Make sure the add-in card is seated securely in the expansion
slot. If the add-in card is loose, power off the system, re-install
the card and power up the system.
2. Check the jumper settings to ensure that the jumpers are
properly set.
3. Verify that all SIMMs are seated securely into the SIMM sockets.
4. Make sure the SIMMs are in the correct locations.

5. If the board fails to function, place the board on a flat surface
and seat all socketed components. Gently press each
component into the socket.
6. If you made changes to the BIOS settings, re-enter setup and
load the BIOS defaults.
