Chapter 2

Hardware Installation

This chapter summarizes the steps to install the C586VX 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 C586VX 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.

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 C586VX 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.

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 C586VX 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 tech­niques.

6. Insert the memory modules into the memory banks on the C586VX.
The quantity and location of the memory modules depends on 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
C586VX. Refer to the Cache Memory section on page 16 for up­grading 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 C586VX 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 C586VX system board supports two kinds of memory modules:
DIMM and SIMM. DIMM, which uses SDRAM, performs better than
SIMM, which uses DRAM.

DIMM

The DIMM (Dual In-line Memory Module) socket uses x64 EDO, FPM
and SDRAM. The C586VX system board can support 8MB to 16MB
memory using 1MBx64 or 2MBx64 168-pin DIMM. Refer to page 12 for
the location of the DIMM.

Installing the DIM Module

A DIM module simply snaps into a socket on the system board. Pin 1 of
the DIM module must correspond with Pin 1 of the socket.

Notch

Tab

Pin 1

Key

Tab

1. Pull the "tabs" which are at the ends of the socket to the side.

2. Position the DIMM above the socket with the "notches" in the mod-

ule aligned with the "keys" on the socket.

3. Seat the module vertically into the socket. Make sure it is completely

seated. The tabs will hold the DIMM in place.

13

SIMM

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. The system board will not work
if you install 1 or 3 pieces. 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 C586VX system board can support 8MB to 128MB of memory us­ing 1MBx32, 2MBx32, 4MBx32, or 8MBx32 72-pin SIMMs. The table
below shows the supported SIM modules and their corresponding
memory sizes.

SIMMs

1MBx32
2MBx32
4MBx32
8MBx32

Memory Size

4MB
8MB
16MB
32MB

Examples:
If you are installing 8MB of memory, you must insert two 1MBx32

SIMMs in Bank 0 or Bank 1. Inserting one 2MBx32 module will not
work.

If you are installing 24MB of memory, you must insert two 1MBx32
SIMMs in Bank 0 and two 2MBx32 SIMMs in Bank 1. You may also
install it vice versa by inserting two 1MBx32 SIMMs in Bank 1 and two
2MBx32 SIMMs in Bank 0.

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 .

14

notch

key

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 com­pletely seated. Tilt the module upright until it locks in place in the
socket.

Warning:

The DIMM and SIMM can not exist on the C586VX system board at the
same time. You must only use either a DIMM or SIMMs on your system
board.

Cache Memory

The C586VX system board can support 256KB or 512KB pipeline burst,
direct map write-back cache SRAM. Your system board may come with
256KB or 512KB cache mounted onboard. The 160-pin cache module
slot lets you upgrade your cache memory by installing a 256KB 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 256KB cache at locations 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 locations of the cache module slot (SSM1), U22 and U23.

Warning:

We highly recommend that you use Tthe 2BSM32-256 cache module. If
you are using the cache module other than the one recommended
above, make sure your cache module meets the Intel COAST 2.x speci­fication. 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 (SSM1).
Refer to page 12 for the location of SSM1. 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 compo­nents on the solder side of the add-in card in PCI Slot 3 must not pro­trude more than 5mm. The components of the component side of the
add-in card in PCI Slot 2 also must not protrude more than 5mm.

17

CPU Installation

The C586VX allows for easy installation of CPUs. Make sure all jumpers are
set correctly before applying power or you may damage the CPU or system
board. Please see the jumper settings on the following pages. Use the
needle-nosed pliers to move the jumpers if necessary.

Installing Upgrade CPUs

The C586VX is equipped with a 321-pin Zero Insertion Force (ZIF)
socket at location U25 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.

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 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.

Zero Insetion Force (ZIF) Socket

21

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.

22

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 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.

Installing A Fan/Heatsink for Cyrix CPUs

If you are using a Cyrix CPU, you must choose a fan/heatsink which is
made for Cyrix processors. Position the fan/heatsink on the CPU such
that the air from the side of the fan/heatsink will flow across the heat
regulators on the system board. See the figure on the next page.

23

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).

Built-in Ports

The C586VX system board is equipped with two serial ports, one paral­lel printer port, one FDD connector, two IDE hard disk shrouded head­ers and one PS/2 mouse connector. Refer to page 12 for the locations
of the built-in connectors and pin 1 of those connectors.

Serial Ports

The built-in serial ports are RS-232C asynchronous communication
ports with 16C550A-compatible UARTs that can be used with modems,
serial printers, remote display terminals, and other serial devices. They
use the following system I/O addresses:

Connecting the Serial Ports

Two DB-9P serial port cables are provided with the system board. 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 J4 on the system board. The lower
serial port cable should be used for the COM 2 secondary serial port;
connect it to connector J5 on the system board. Make sure the colored
stripes on the ribbon cables are aligned with pin 1 of connectors J4 and
J5. Mount the card-edge bracket to the system chassis.

PS/2 Mouse Port

The PS/2 mouse port is a 6-pin connector on the system board. Attach
the 6-pin mouse port cable, which is mounted on the card-edge bracket,
to connector J3. Make sure the brown wire on the PS/2 mouse connec­tor is aligned with pin 1 of connector J3.

Parallel Port

The C586VX system board has a standard connector for interfacing
your PC to a parallel printer. The parallel port on your system board can
be set to any of the following system I/O addresses:

I/O Address: 3BC-3BE Hex

378-37A Hex (default)
278-27A Hex

Connecting the Parallel Printer Port

Attach the DB-25S printer cable, which came with the system board, to
connector J7 on the C586VX system board. Make sure the colored
stripe on the ribbon aligns with pin 1 of connector J7. Use a small
nutdriver to mount the cable into a DB-25 cutout in the system chassis.
You may also use the cable to the card-egde bracket which came with
the system board. After attaching the cable to the card-edge bracket,
mount the bracket to the system chasis.

27

Floppy Disk Drive Controller

The C586VX system board has a built-in floppy disk controller that sup­ports two standard floppy disk drives. You can install any 360KB,
720KB, 1.2MB, 1.44MB, or 2.88MB floppy disk drives.

Connecting the Floppy Disk Cable

1. Install the 34-pin header connector into the floppy disk connector
(J6) on the system board. The colored edge of the ribbon should be
aligned with pin 1 of connector J6.

2. Install the other 34-pin header connector(s) into the disk drive(s).
Align the colored edge of the daisy chained ribbon cable with pin 1
of the drive edge connector(s). The end-most connector should be
attached to the drive you want to designate as Drive A.

IDE Hard Disk Interface

The C586VX system board is equipped with two PCI IDE shrouded
headers that will interface four Enhanced IDE (Integrated Drive Elec­tronics) hard disk drives.

Note:

Only Enhanced IDE hard drives or ATAPI CD-ROMs 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 40-pin 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.

28

Header

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
J8). 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 (connector J9).

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.

29

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 C586VX 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.
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 also can
use the “IDE Auto Detection” to set your IDE Drive mode, please refer
to the relevant information on the section “IDE Auto Detection”.

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.

Installing Expansion Cards

The C586VX system board is equipped with 4 dedicated PCI slots and
3 dedicated 16-bit ISA slots. All PCI slots are bus masters.

Due to the size of the CPU with its accompanying fan/heatsink compo­nent, the length of the add-in cards in PCI slot 4 and ISA slot 1 is
limited to 18cm (7.07", measured from the bracket of the card). With the
cache module installed in the cache module slot, the components on
the solder side of the add-in card in PCI Slot 3 must not protrude more
than 5mm. The components of the component side of the add-in card
in PCI Slot 2 also must not protrude more than 5mm.

Refer to page 12 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 “PCI Configuration Setup” presented in the
“Software Installation” section of the manual.

Chipset Features Setup

The C586VX system board uses the Intel 82430VX chipset. This sec­tion allows you to configure the system based on the specific features
of the chipset. This chipset manages bus speeds and access to system
memory resources, such as DRAM and the external cache. It also coor­dinates communications between the conventional ISA bus and the PCI
bus. These items should not be altered unless necessary. The default
settings have been chosen because they provide the best operating
conditions for your system. The only time you might consider making
any changes would be if you discovered that data was being lost while
using your system.

The HDD Power Down mode will be set to one minute.
The option defines the continuous HDD idle that elapses be­fore the HDD enters the power saving mode (motor off).
Note: When a HDD is in power saving mode, any access to

the HDD will wake up the HDD.

Wake Up Event In Doze & Standby (IRQ3, 4, 8 and 12)

The default value is On.

On

Off

The activity of this wake-up event causes the timers to be
reset, i.e., the Power Management Unit (PMU) monitors the
specified activities as power management events.
The activity of this event will not affect the power manage­ment timers.

Power Down & Resume Events (IRQ 3 - 15)

Power Down and Resume events 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 down mode.

The following is a list of IRQ's, Interrupt ReQuests, which can be ex­empted much as the COM ports and LPT ports above can. 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 on, activity will neither prevent the system from going into a
power management mode nor awaken it.

The default value is On.

45

On

The activity of this event causes the power management tim­ers to be reset, i.e., the Power Management Unit (PMU)
monitors the specified activities as power management
events.

Off

The activity of this event will not affect the power manage­ment timers.

PNP/PCI Configuration Setup

This section describes configuring the PCI bus system. PCI, or Personal
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.

The interrupt will be controlled by the level.
The interrupt will be controlled by the edge.

PCI IDE IRQ Map To

This allows you to configure your system to the type of IDE disk control­ler in use. By default, setup assumes that your controller is an ISA de­vice rather than a PCI controller. The more apparent difference is the
type of the slot being used.

If you have equipped your system with a PCI controller, changing this
allows you to specify which slot has the controller and which PCI inter­rupt (A, B, C or D) is assumed with the connected hard devices.

This setting refers to the hard disk drive itself, rather than individual
partitions. Since each IDE controller supports two separate hard drives,
you can select the INT# for each. You will note that the primary has a
lower interrupt than the secondary.

Selecting "PCI Auto" allows the system to automatically determine how
your IDE disk system is configuration. The default value is PCI-Auto.

47

PCI-Auto

IDE Primary or Secondary Master/Slave PIO

IDE hard drive controllers can support up to two separate hard drives.
These drives have a master/slave relationship which are determined by
the cabling configuration used to attach them to the controller. Your
system supports two IDE controllers - a primary and a secondary - so
you have to ability to install up to four separate hard disks.

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. The simpler and more
efficient (and faster).

49

Your system supports five modes, numered from 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select the
best available mode.

Auto

Mode 0-4

The BIOS will set the system board to fit the hard disk drive
timing automatically.

ESC: Skip

Enter your choice, and press <Enter> to accept the parameters or press
<Esc> to abort. The parameters of the hard disk will be displayed in the
Standard CMOS Setup.

Hard Drive Mode

The C586VX 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.

53

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 ( 225)
x no.Sectors ( 63)
x bytes per sector ( 512)

8.4 gigabytes

54

Large Mode

Large mode is the extended HDD access mode supported by the
C586VX system boards. Some IDE HDDs have more than 1024 cylin­ders without LBA support (in some cases, you may not want the LBA
mode). These system boards provide 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 Service 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
