Viglen VIG520S Motherboard Manual Version 1.00

Viglen, EMC and the ‘CE’ mark

CE Marking
European standards are being harmonised across borders. If products comply to the same
standards in all European countries, product exporting and importing is made simple - paving our
way to a common market. If you buy a product with a 'CE' mark on it (shown below), on the box, in
the manual, or on the guarantee - it complies to the currently enforced directive(s).

Introduction to EMC
EMC (Electromagnetic Compatibility) is the term used to describe certain issues with RF (Radio
Frequency) energy. Electrical items should be designed so they do not interfere with each other
through RF emissions. E.g. If you turn on your microwave, your television shouldn't display
interference if both items are CE marked to the EMC directive.

If emitted RF energy is not kept low, it can interfere with other electrical circuitry - E.g. Cars
Automatic Braking Systems have been known to activate by themselves while in a strong RF field.
As this has obvious repercussions ALL electrical products likely to cause RF related problems have
to be 'CE' marked from 1st January 1996 onwards.

If a product conforms to the EMC directive, not only should its RF emissions be very low, but its
immunity to RF energy (and other types) should be high. The apparatus has to resist many
'realworld' phenomena such as static shocks and mains voltage transients.

Viglen’s Environment laboratory
To gain a 'CE' mark, the Viglen computer range has had to undergo many difficult tests to ensure it
is Electromagnetically Compatible. These are carried out in the in-house 'Environment lab' at Viglen
Headquarters. We have made every effort to guarantee that each computer leaving our factory
complies fully to the correct standards. To ensure the computer system maintains compliance
throughout its functional life, it is essential you follow these guidelines.

>Install the system according to Viglen’s instructions
>If you open up your Viglen:
> Keep internal cabling in place as supplied.
> Ensure the lid is tightly secured afterwards
> Do not remove drive bay shields unless installing a 'CE' marked peripheral in its
place
> The clips or ‘bumps' around the lips of the case increase conductivity - do not
remove or damage.
> Do not remove the ferrite ring from the L.E.D cables.
> Only use your Viglen computer with 'CE' marked peripherals

This system has been tested in accordance with European standards for use in residential and light
industrial areas-this specifies a 10 meter testing radius for emissions and immunity. If you do
experience any adverse affects which you think might be related to your computer, try moving it at
least 10 meters away from the affected item. If you still experience problems, contact Viglen’s
Technical Support department who will put you straight through to an EMC engineer - s/he will do
everything possible to help. If modifications are made to your Viglen computer system, it might
breach EMC regulations. Viglen take no responsibility (with regards to EMC characteristics) of
equipment which has been tampered with or modified.

DDR

DDR transfers data twice as fast as SDR SDRAM modules. This does not mean your
system will run twice as fast, but your memory will. And the faster memory will
improve your PC's performance.

Note:

All memory components and DIMMs used with the VIG520S motherboard must
comply with the PC DDR specifications.

In addition to the above, the motherboard will be supplie d with DDR memory only.
Should you wish to use SDR memory, you will need to remove the DDR memory
first. This is because the board will support EITHER DDR or SDR and not both
simultaneously.

14 of 85

Note:

Computer systems that have an unshielded cable attached to a USB port may not
meet FCC Class B requirements, even if no device or a low-speed (sub-channel)
USB device is attached to the cable. Use shielded cable that meets the
requirements for high-speed (fully rated) devices.

IDE Support

The motherboard has two independent bus-mastering PCI IDE interfaces. These
interfaces support PIO Mode 3, PIO Mode 4, ATAPI devices (e.g., CD-ROM), Ultra
DMA/33, Ultra DMA/66, Ultra DMA/100 & Ultra DMA/133 synchronous-DMA mode
transfers. The BIOS supports logical block addressing (LBA) and extended cylinder
head sector (ECHS) translation modes. The BIOS automatically detects the IDE
device transfer rate and translation mode.

Programmed I/O operations usually require a substantial amount of processor
bandwidth. However, in multitasking operating systems, the bandwidth freed by bus
mastering IDE can be devoted to other tasks while disk transfers are occurring.

LS-120 Support

LS-120 MB Diskette technology enables you to store 120MB of data on a single, 3.5”
removable diskette. LS-120 technology is backward (both read and write)
compatible with 1.44MB and 720KB DOS-formatted diskette and is supported by
Windows 95 and Windows NT operating system.

The VIG520S board allows connection of an LS-120 compatible drive and a standard
3½” floppy drive. The LS-120 drive can be configured as a boot device before a
floppy drive, if selected in the BIOS setup utility.

Note:

If you connect an LS-120 drive to an IDE connector and configure it as the “A” drive
and configure a standard 3.5” floppy as “B” drive, the standard floppy must be
connected to the floppy drive cable’s “A” connector (the connector at the end of the
cable).

The BIOS setup utility can be configured to boot firstly from either the LS120 or

standard 3½“ floppy drive.

Real-Time Clock, CMOS SRAM, and Battery

The real-time clock is compatible with DS1287 and MC146818 components. The
clock provides a time-of-day clock and a multicentury calendar with alarm features
and century rollover. The real-time clock supports 256 bytes of battery-backed
CMOS SRAM in two banks that are reserved for BIOS use.

15 of 85

The time, date, and CMOS values can be specified in the Setup program. The
CMOS values can be returned to their defaults by using the Setup program.
An external coin-cell (CR 2032) battery powers the real-time clock and CMOS
memory. When the computer is not plugged into a wall socket, the battery has an
estimated life of three years. When the computer is plugged in, the 3.3-V standby
current from the power supply extends the life of the battery. The clock is accurate

to ± 13 minutes/year at 25 ºC with 3.3 V applied.

connector located on the back panel. In the Setup program, the parallel port can be
configured for the following:

• Compatible (standard mode).

• Bi-directional (PS/2 compatible).

• Extended Parallel Port (EPP).

• Enhanced Capabilities Port (ECP).

16 of 85

Floppy Controller

The I/O controller is software compatible with the N82077 floppy drive controllers
and supports both PC-AT and PS/2 modes. In the Setup program, the floppy
interface can be configured for the following floppy drive capacities and sizes:

• 360 KB, 5.25-inch

• 1.2 MB, 5.25-inch

• 720 KB, 3.5-inch

• 1.2 MB, 3.5-inch (driver required)

• 1.25/1.44 MB, 3.5-inch

• 2.88 MB, 3.5-inch

PS/2 Keyboard and Mouse Interface

PS/2 keyboard and mouse connectors are located on the back panel. The +5 V lines
to these connectors are protected with a PolySwitch circuit that, like a self-healing
fuse, re-establishes the connection after an over-current condition is removed.

The keyboard controller also supports the hot-key sequence <Ctrl><Alt><Del> for a
software reset. This key sequence resets the computer’s software by jumping to the
beginning of the BIOS code and running the Power-On Self Test (POST).

Audio Subsystem

The VIG520S board has multiple AC ’97 V 2.2 compliant audio features.

The audio subsystem includes these features:

• High performance 3D technology

• Energy saving power down modes

• 6 channels for full surround sound capability

System BIOS

The system BIOS, from Award Technology, provides ISA and PCI compatibility. The
BIOS is contained in a flash memory device on the system board. The BIOS
provides the power-on self test (POST), the system Set-up program, a PCI and IDE
auto-configuration utility, and BIOS recovery code.

PCI Auto Configuration

The PCI auto-configuration utility works in conjunction with the Set-up program to
support using PCI add-in boards in the system. When you turn on the system power
after installing a PCI board, the BIOS automatically configures interrupts, DMA
channels, I/O space, and so on. Since PCI add-in boards use the same interrupt
resources as ISA add-in boards, you must specify the interrupts used by ISA boards
in the set-up program. The PCI auto-configuration program complies with version 2.2
of the PCI BIOS specification.

17 of 85

IDE Auto Configuration

If you install an IDE drive in the system, the IDE auto-configuration utility
automatically detects and configures the drive for operation in the system. This

utility eliminates the need to enter the Set-up program after you install an IDE drive.

Expansion Slots

The system has three PCI bus add-in card connectors, one AGP slot.

STEPS TO TAKE TO PREVENT STATIC DISCHARGE:

1. The best way to prevent static discharge is to buy an anti-static strap from your
local electrical shop. While you are wearing the strap and it is earthed, static
charge will be harmlessly bled to ground.

2. Do not remove the component from its anti-static protective packaging until you
are about to install it.

3. Hold boards by the edges - try not to touch components / interface strips etc.

Note:

We recommend that you return your computer to the service department for
upgrading. Any work carried out is fully guaranteed. Upgrades should only be carried
out by persons who are familiar with handling IC's, as incorrect installation will
invalidate the guarantee.

Jumper Settings

Caution!

Never remove jumpers using large pliers as this can damage the pins. The
best way to remove a jumper is to use a small pair of tweezers or fine needle­nosed pliers.

Never remove a jumper when the computer is switch on. Always switch the
computer off first.

USB device wake-up (3-pin USBPWR_12, USBPWR_34, USBPWR_56)

Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU
stopped, DRAM refreshed, system running in low power mode) using the
connected USB devices. Set to +5VSB to wake up from S3 sleep mode (no
power to CPU, DRAM in slow refresh, power supply in reduced power mode).
Both jumpers are set to pin 2-3 (+5VSB) by default.

The USBPWR_12, and USBPWR_34 jumpers are for the rear USB ports. The
USBPWR_56 is for the internal USB header that you can connect to the front
USB ports.

Clear RTC RAM (CLRTC1)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can
clear the CMOS memory of date, time and system setup parameters by erasing the
CMOS RTC RAM data. The RAM data in CMOS, that includes system setup
information such as system passwords, is powered by the onboard button cell
battery.

21 of 85

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power chord

2. Remove the onboard battery

3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins
2-3 for about 5~10 seconds, then move the cap back to pins 1-2.

4. Replace the battery

5. Plug the power chord in and turn ON the computer.

6. Hold down the <Del> key during the boot process and enter BIOS setup to re­enter data.

Motherboard Connectors

There are connectors on the motherboard for Floppy drive, IDE drives, COM Port,
Power connectors, Front USB, Front Panel Audio, Internal audio connectors and
System front panel connectors. The location and/or details of these connections are
shown below.

Floppy disk drive connector (34-1 pin FLOPPY1)

This connector supports the provided floppy drive ribbon cable. After connecting one
end to the mother board, connect the other end to the floppy drive. (Pin 5 is removed
to prevent incorrect insertion when using the ribbon cables with pin 5 plug).

IDE connectors (40-1 pin PRI_IDE1, SEC_IDE1)

If you install two hard disks, you must configure the second drive as a slave device
by setting its jumper accordingly. Refer to the hard disk documentation for these
settings. The BIOS supports specific device boot up.

23 of 85

COM1 connector (10-1 pin COM1)

This connector accommodates a serial port using an optional serial port bracket.
Connect the bracket cable to this connector and then install the bracket into a slot
opening at the back of the system chassis.

ATX power connectors (20-pin ATXPWR1, 4-pin ATX12V1)

These connectors connect to an ATC 12V power supply. The plugs from the power
supply are designed to fit these connectors in only one orientation. Find the proper
orientation and push down firmly until the connectors completely fit. In addition to the
20-pin ATXPWR1 connector, this motherboard requires that you connect the 4-pin
ATX +12V power plug to provide sufficient power to the CPU.

24 of 85

CPU and Chassis Fan connectors (3-pin CPU_FAN1, CHA_FAN1)

The fan connectors support cooling fans of 350mA ~ 740mA (8.88W max.) or a total
of 1A ~ 2.22A (26.64W max.) at +12V. Connect the fan cables to the fan connectors
on the motherboard, making sure that the black wire of each cable matches the
ground pin of the connector.

USB header (10-1 pin USB_56)

The USB header complies with USB 2.0 specification that supports up to 480 Mbps
connection speed. This speed advantage over the faster conventional 12Mbps on
USB 1.1 allows faster Internet connection, interactive game, and simultaneous
running of high speed peripherals.

25 of 85

Front panel audio connector (10-1 pin FP_AUDIO1)

This is an interface for the Intel front panel audio cable that allows convenient
connection and control of audio devices.

Internal Audio connectors (4-pin CD1, AUX1)

These connectors allow you to receive stereo audio input from sound sources such
as a CD-ROM, TV-tuner or MPEG card.

26 of 85

System panel connector (20-pin PANEL1)

This connector accommodates several system front panel functions.

System Power LED Lead (3-1 pin PLED)

This 3-1 pin connector connects to the system power LED. This LED lights up when
you turn on the system power, and blinks when the system is in sleep mode

System Warning Speaker Lead (4-pin SPEAKER)

This 4-pin connector connects to the case-mounted speaker and allows you to hear
system beeps and warnings.

ATX Power Switch / Soft-Off Switch Lead (2-pin PWRBTN)

This connector connects a switch that controls the system power. Pressing the
power switch turns the system between ON and SLEEP, or ON and SOFT OFF,
depending on the BIOS or OS settings. By holding the power switch when in the ON
mode for more than 4 seconds turns the system OFF.

Reset Switch Lead (2-pin RESET)

The 2-pin connector connects to the case-mounted reset switch for rebooting the
system without turning off the system power.

Hard Disk Activity Lead (2-pin IDE_LED)

This connector supplies power to the hard disk activity LED. The read or write
activities of any device connected to the primary or the secondary IDE connector
cause this LED to light up.

Installing & Removing Dual In-line Memory Modules DIMMs

Installing Memory

You can install from 64MB to 2GB of memory in the motherboard DIMM sockets.
The board has DIMM sockets arranged as banks 0 & 1. The motherboard supports
the following memory features:

• 184-pin DDR / 168-pin SDR DIMMs with gold-plated contacts.

• 333/266MHz DDR / 100/133 SDR RAM, PC2700/2100/PC1600 compliant.

• 64 MB, 128 MB, 256 MB, 512MB and 1GB modules.

When adding memory, follow these guidelines:

• You can install DIMMs in any of the banks.

• You can use different size DIMMs in different banks.

• The BIOS detects the size and type of installed memory.

• Please note, the motherboard will not support DDR and SDR at the same

time

To install DIMMs, follow these steps:

1. Observe the precautions in “Before You Begin”. Turn off the computer and
all peripheral devices.

2. Remove the computer cover and locate the DIMM sockets.

3. Holding the DIMM by the edges, remove it from its antistatic package.

4. Make sure the clips at either end of the socket are pushed away from the
socket.

5. Position the DIMM above the socket. Align the two small notches in the
bottom edge of the DIMM with the keys in the socket. Insert the bottom edge
of the DIMM into the socket.

6. When the DIMM is seated, push down on the top edge of the DIMM until the
retaining clips at the ends of the socket snap into place. Make sure the clips
are firmly in place.

7. Replace the computer cover.

29 of 85

8. If you installed a DIMM with ECC memory, start the computer and use the
ECC Configuration feature in Setup to enable the use of ECC.

Removing Memory

To remove a DIMM, follow these steps:

1. Observe the precautions in "Before You Begin”.

2. Turn off all peripheral devices connected to the computer. Turn off the
computer.

3. Remove the computer cover.

4. Gently spread the retaining clips at each end of the socket. The DIMM pops
out of the socket.

5. Hold the DIMM by the edges, lift it away from the socket, and store it in an
antistatic package.

6. Reinstall and reconnect any parts you removed or disconnected to reach the

DIMM sockets.

Replacing the Clock/CMOS RAM Battery

A lithium battery is installed in a socket on the system board. The battery has an
estimated life expectancy of seven years. When the battery starts to weaken, it
loses voltage; when the voltage drops below a certain level, the system settings
stored in CMOS RAM (for example, the date and time) may be wrong.

If the battery fails, you will need to replace it with a CR2032 battery or an equivalent.
As long as local ordinance permits, you may dispose of individual batteries as
normal rubbish. Do not expose batteries to excessive heat or any naked flame.
Keep all batteries away from children.

CAUTION!

Danger of explosion if the battery is incorrectly replaced. Replace only with the
same or equivalent type recommended by Viglen. Discard used batteries according
to manufacturer’s instructions.

30 of 85

The battery is listed as board component ‘T’ on the diagram on page 6.
It is located near to the main motherboard front panel connectors.

To replace the battery, carry out the following:

1. Observe the precautions in “Before You Begin.”

2. Turn off all peripheral devices connected to the system.

3. Turn off the system.

4. Remove any components that are blocking access to the battery.

Troubleshooting Procedure

This section provides a step-by-step troubleshooting procedure to identify a problem
and locate its source.

CAUTION!

1. Turn off the system and any peripheral devices before you disconnect any
peripheral cables from the system. Otherwise, you can permanently damage the
system or the peripheral devices.

2. Make sure the system is plugged into a properly grounded power outlet.

3. Make sure your keyboard and video display are correctly connected to the
system. Turn on the video display, and turn up its brightness and contrast
controls to at least two-thirds of the maximum (refer to the documentation supplied
with the video display).

4. If the operating system normally loads from the hard disk drive, make sure there is
no diskette in the diskette drive. If the operating system normally loads from a
diskette, insert the operating system diskette into the drive.

5. Turn on the system. If the power indicator does not light, but the system seems
to be operating normally, the indicator is probably defective. Monitor the power-on
self test (POST) execution. Each time you turn on the system, the POST checks
the system board, memory, keyboard, and certain peripheral devices.

Note:
If the POST does not detect any errors, the system beeps once and boots up.

Errors that do not prevent the boot process (non-fatal errors) display a message that
looks similar to the following:
Error Message Line 1
Error Message Line 2
Press <F2> for Set-up, <F1> to Boot

You can note the error and press <F1> to resume the boot- up process, or
<F2> to enter Set-up.

Errors that prevent the boot process from continuing (fatal errors), are communicated
by a series of audible beeps. If this type of error occurs, refer to the error codes and
messages listed at the end of this chapter.

6. Confirm that the operating system has loaded.

Problems Operating Add-in Boards

Problems related to add-in boards are usually related to improper board installation
or interrupt and address conflicts. Go through the checklist below to see if you can
correct the problem. If the problem persists after you have checked and corrected all
of these items, contact the board vendor's customer service representative. Did you
install the add-in board according to the manufacturer’s instructions? Check the
documentation that came with the board. Are all cables installed properly?

The following items are suggestions for troubleshooting problems related to PCI
legacy (non-Plug and Play) add-in boards.

 If the PCI board uses an interrupt, run Set-up and set the interrupt that is being

used by the PCI board to Used by PCI Card. Please refer to the BIOS manual for
details of how to do this.

 If the PCI legacy board uses memory space between 80000H - 9FFFFH, run Set-

up and set conventional memory to 256 K.

 If the PCI legacy board uses shared memory between C8000H - DFFFH, run Set-

up and enable shared memory for the appropriate memory space.

BIOS Beep Codes

If an unrecoverable hardware problem occurs the computer may emit a number of
beeps from the speaker. These are known as beep codes. The pitch and duration
of the beep codes may vary but there will always be a set number of beeps. These
beeps stem from the BIOS’s initial check on the system and will normally occur in the
first few seconds of power on.

Beeps codes represent a terminal error. If the BIOS detects a terminal error
condition, it outputs an error beep code, halts the POST, and attempts to display a
port 80h code on a POST card’s LED display.

Table 8: Beep Codes

Chapter 4 System BIOS

What is the BIOS?

The BIOS (Basic Input Output System) is an important piece of software which is
stored in a ROM (Read Only Memory) chip inside the computer. It consists of the
basic instructions for controlling the disk drives, hard disk, keyboard and
serial/parallel ports. The BIOS also keeps a list of the specifications of the computer
in battery-backed RAM (also known as the CMOS RAM) and provides a special
Setup program to change this information.

The BIOS in your Viglen computer is guaranteed to be fully compatible with the IBM
BIOS. It has been written by Phoenix Technology Ltd., an industrial leader in the field
of BIOS software.

The Power-on sequence

When the computer is first switched on, certain instructions in the BIOS are executed
to test various parts of the machine. This is known as the POST (Power-On Self
Test) routine. When you switch the computer on (or when you press the Reset
button or press <Ctrl + Alt + Del> keys, which has the same effect), you can see on
the monitor that it counts through the memory, testing it. The floppy disk drives are
then accessed and tested, and the various interfaces are checked. If there are any
errors, a message is displayed on the screen.

Having passed all the tests, and if you have activated the password facility, the BIOS
then asks you to enter the boot password to continue. The following section
describes how to do this. The BIOS then loads the operating system, either - MS
DOS, Windows 95, OS/2 or NetWare, etc. - from the hard disk (or floppy disk if one
is inserted in Drive A:). The computer is then ready for use.

AWARD BIOS

Introduction

The motherboard uses an AWARD BIOS, which is stored in flash memory and can
be upgraded using a disk-based program. In addition to the BIOS, the flash memory
contains the Setup program, Power-On Self Test (POST), Advanced Power
Management (APM), the PCI auto-configuration utility, and is Windows 95-ready
Plug and Play. This motherboard supports system BIOS shadowing, allowing the
BIOS to execute from 64-bit onboard write-protected DRAM.

The BIOS displays a message during POST identifying the type of BIOS and the
revision code.

BIOS Upgrades

A new version of the BIOS can be upgraded from a diskette using the AFLASH.EXE
utility that is available from Viglen. This utility does BIOS upgrades as follows:

• Updates the flash BIOS from a file on a disk.

• Updates the language section of the BIOS.

• Makes sure that the upgrade BIOS matches the target system to prevent

accidentally installing a BIOS for a different type of system.

• Backup the current BIOS before upgrading to newer BIOS note BIOS

settings before hand.

• If you encounter a problem unsuccessfully updating new BIOS do not switch

off load saved BIOS or system may not be able to boot.

BIOS upgrades and the Flash utility may be available from your system supplier.

Note:

Please review any instructions distributed with the upgrade utility before
attempting a BIOS upgrade.

Main BIOS Block

Plug and Play: PCI Auto-configuration

The BIOS automatically configures PCI devices and Plug and Play devices. PCI
devices may be onboard or add-in cards. Plug and Play devices are ISA add-in
cards built to meet the Plug and Play specification. Auto-configuration lets a user
insert or remove PCI or Plug and Play cards without having to configure the system.
When a user turns on the system after adding a PCI or Plug and Play card, the BIOS
automatically configures interrupts, the I/O space, and other system resources. Any
interrupts set to Available in Setup are considered to be available for use by the add­in card.

PCI interrupts are distributed to available ISA interrupts that have not been assigned
to an ISA card or to system resources. The assignment of PCI interrupts to ISA
IRQs is non-deterministic. PCI devices can share an interrupt, but an ISA device
cannot share an interrupt allocated to PCI or to another ISA device. Auto­configuration information is stored in the extended system configuration data (ESCD)
format.

42 of 85

PCI IDE Support

If Auto is selected as a primary or secondary IDE in Setup, the BIOS automatically
sets up the two local-bus IDE connectors with independent I/O channel support. The
IDE interface supports hard drives up to PIO Mode 4 and recognises any ATAPI
devices, including CD-ROM drives, tape drives and Ultra DMA drives. Add-in ISA
IDE controllers are not supported. The BIOS determines the capabilities of each
drive and configures them so as to optimise capacity and performance. To take
advantage of the high-capacity storage devices, hard drives are automatically
configured for logical block addressing (LBA) and to PIO Mode 3 or 4, depending on
the capability of the drive. To override the auto-configuration options, use the
specific IDE device options in Setup. The ATAPI specification recommends that
ATAPI devices be configured as shown in Table 10.

ISA Plug and Play

If Plug and Play operating system is selected in Setup, the BIOS auto-configures
only ISA Plug and Play cards that are required for booting (IPL devices). If Plug and
Play operating system is not selected in Setup, the BIOS auto-configures all Plug
and Play ISA cards.

Desktop Management Interface (DMI)

Desktop Management Interface (DMI) is an interface for managing computers in an
enterprise environment. The main component of DMI is the management
information format (MIF) database, which contains information about the computing
system and its components. Using DMI, a system administrator can obtain the
system types, capabilities, operational status, and installation dates for system
components. The MIF database defines the data and provides the method for
accessing this information. The BIOS enables applications such as Intel LANDesk®
Client Manager to use DMI. The BIOS stores and reports the following DMI
information:

− BIOS data, such as the BIOS revision level.

− Fixed-system data, such as peripherals, serial numbers, and asset tags.

− Resource data, such as memory size, cache size, and processor speed.

− Dynamic data, such as event detection and error logging.

DMI does not work directly under non-Plug and Play operating systems (e.g.,
Windows NT). However, the BIOS supports a DMI table interface for such operating
systems. Using this support, a DMI service-level application running on a non-Plug
and Play OS can access the DMI BIOS information.

Advanced Power Management (APM)

The BIOS supports APM and standby mode. The energy saving standby mode can
be initiated in the following ways:

− Time-out period specified in Setup.

− Suspend/resume switch connected to the front panel sleep connector.

− From the operating system, such as the Suspend menu item in Windows 95.

In standby mode, the motherboard reduces power consumption by using SMM
capabilities, spinning down hard drives, and reducing power to or turning off VESA
DPMS-compliant monitors. Power-management mode can be enabled or disabled in
Setup.

While in standby mode, the system retains the ability to respond to external
interrupts and service requests, such as incoming faxes or network messages. Any
keyboard or mouse activity brings the system out of standby mode and immediately
restores power to the monitor.

The BIOS enables APM by default, but the operating system must support an APM
driver for the power-management features to work. For example, Windows 95
supports the power-management features upon detecting that APM is enabled in the
BIOS.

44 of 85

Advanced Configuration and Power Interface (ACPI)

ACPI gives the operating system direct control over the power management and
Plug and Play functions of a computer. ACPI requires an ACPI-aware operating
system. ACPI features include:

• Plug and Play (including bus and device enumeration) and APM

functionality normally contained in the BIOS.

• Power management control of individual devices, add-in boards, video

displays, and hard disk drives.

• Methods for achieving less than 30-watt system operation in the Power

On Suspended sleeping state, and less than 5-watt system operation in
the Suspended to Disk sleeping state.

• A soft-off feature that enables the operating system to power off the

computer.

• Support for multiple wake up events.

• Support for a front panel power and sleep mode switch. Table 11

describes the system states based on how long the power switch is
pressed, depending on how ACPI is configured with an ACPI-aware
operating system.

Table 11: Effects of Pressing the Power Switch

If the system is in
this state…

… and the power
switch is pressed for

…the system enters
this state

Off Less than 4 seconds Power On
On Less than 4 seconds Soft Off/ Suspended
On More than 4 seconds Fail safe power off
Sleep Less than 4 seconds Wake up

Under ACPI, the operating system directs all system and device power state
transitions. The operating system puts devices in and out of low-power state based
on user preferences and knowledge of how devices are being used by applications.
Devices that are not being used can be turned off.

Table 12 lists the power states supported by the motherboard along with the
associated system power targets.

Language Support

The Setup program and help messages can be supported in 32 languages. The
default language is American English, which is present unless another language is
programmed into the BIOS using the flash memory update utility.

Boot Options

In the Setup program, the user can choose to boot from a floppy drive, hard drive,
CD-ROM, or the network. The default setting is for the floppy drive to be the primary
boot device and the hard drive to be the secondary boot device. By default the third
and fourth devices are disabled.

Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM
format specification. Under the Boot menu in the Setup program, CD-ROM is listed
as a boot device. Boot devices are defined in priority order. If the CD-ROM is
selected as the boot device, it must be the first device.

The network can be selected as a boot device. This selection allows booting from a
network add-in card with a remote boot ROM installed.

USB Support

The USB connectors allow any of several USB devices to be attached to the
computer. Typically, the device driver for USB devices is managed by the operating
system. However, because keyboard and mouse support may be needed in the
Setup program before the operating system boots, the BIOS supports USB
keyboards and mice.

BIOS Setup Access

Access to the Setup program can be restricted using passwords. User and
supervisor passwords can be set using the Security menu in Setup. The default is
no passwords enabled.

Configuring the Motherboard BIOS using Setup

Before You Begin

CAUTION!

• Always follow the steps in each procedure in the correct order.

• Set up a log to record information about your computer, such as

model, serial numbers, installed options, and configuration
information.

• Use an anti-static wrist strap and a conductive foam pad when working

on the motherboard.

WARNINGS

The procedures in this chapter assume familiarity with the general terminology
associated with personal computers and with the safety practices and
regulatory compliance required for using and modifying electronic equipment.

Disconnect the computer from its power source and from any
telecommunications links, networks, or modems before performing any of the
procedures described in this chapter. Failure to disconnect power,
telecommunications links, networks, or modems before you open the computer
or perform any procedures can result in personal injury or equipment damage.
Some circuitry on the motherboard may continue to operate even though the
front panel power button is off.

CAUTION!

Electrostatic discharge (ESD) can damage components. Perform the
procedures described in this chapter only at an ESD workstation. 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
computer chassis.

Set Supervisor Password/Set User Password

These two options set the system passwords. “Supervisor Password” sets a
password that will be used to protect the system and the Setup utility; “User
Password” sets a password that will be used exclusively on the system. By default,
the system comes without any passwords. To specify a password, highlight the type
you want and then press the <enter> key. A password prompt appears on the
screen. Taking note that the password is case sensitive, and can be up to 8
alphanumeric characters long, type in your password and then press the <enter>
key. The system confirms your password by asking you to type it again. After
setting a password, the screen automatically reverts to the main screen.

Supervisor Password

If set the Supervisor password allows full access to the BIOS setup Utility menus.

Upgrading the BIOS

Upgrading the BIOS

This chapter describes how to upgrade the BIOS and how to recover the BIOS
if an upgrade fails.

Preparing for the Upgrade

Before you upgrade the BIOS, prepare for the upgrade by recording the current
BIOS settings, obtaining the upgrade utility, and making a copy of the current
BIOS.

Obtaining the Upgrade Utility

You can upgrade to a new version of the BIOS using the new BIOS files and the
BIOS upgrade utility, AFLASH.EXE. You can obtain the BIOS upgrade file and the
utility through Viglen:
http://www.viglen.co.uk

Note:

Please review the instructions distributed with the upgrade utility before
attempting a BIOS upgrade.

This upgrade utility allows you to:

− Upgrade the BIOS in flash memory.

− Update the language section of the BIOS.

The following steps explain how to upgrade the BIOS.

Recording the Current BIOS Settings

Boot the computer and press <DEL> to enter the BIOS.
Write down the current settings in the BIOS Setup program.

Chapter 5 Technical Information

Note:

This chapter is indented for experienced users only, and only to be used as a
reference. Changes to or modify any of the components/ connectors listed herein
can and will seriously damage your system, including the motherboard, CPU and/or
any other hardware.

You do not need to read this chapter to configure your motherboard. If you are not
sure about the details listed herein, please skip and disregard them.

Enhanced IDE

IDE has been used in computer systems for some time, and has been a cheap
solution to data storage. It has now been realized that traditional IDE has its
limitations and thus needed to be improved. This was where Enhanced IDE came
from. The main developments to the IDE interface are:

• Support hard drives of capacity greater than 528MB. This is achieved through

BIOS changes.

• Improved data transfer rates. Transfer rates of 1-3MB/sec were the best to be

expected from older IDE drives. With local bus technology this increased to
about 6MB/sec. Now with multimedia applications, requiring vast amounts of
information, even faster transfers rates were needed. Now drives with
Enhanced IDE controllers can deliver up to 13MB/sec which is in the region of
SCSI-2 performance.

• Dual-IDE channels have now been added which allows up to four IDE drives

to be supported by the system. Each channel supporting two IDE devices.

• Non disk IDE peripherals have been developed (IDE CD-ROMs, IDE tape

streamers) which can be simply attached to the one channel requiring no
special hardware (requiring the use of an ISA slot) or complicated drivers.
This is a standard interface meaning that any IDE CD-ROM or tape streamer
can be attached.

Operating Systems and hard drives

Standard CHS is the translation that has been used for years. Its use limits IDE
capacity to maximum of 528MB regardless of the size of the drive used.

Logical Block mode overcomes the 528MB maximum size limitation imposed by the
Standard CHS mode. It should be used only when the drive supports LBA (Logical
Block Addressing), and the OS supports LBA, or uses the BIOS to access the disk.

Continued 

71 of 85

Extended CHS mode also overcomes the 528MB maximum size limitation imposed
by Standard CHS mode. It can be used with drives which are larger than 528MB that
do not support LBA.

Auto Detected allows the BIOS to examine the drive and determine the optimal
mode. The first choice is to utilise Logical Block mode if it is supported by the drive.
The second choice is to utilise Extended CHS mode if the drive topology allows. If
neither of the above methods is possible, the Standard CHS mode is used.

Different operating systems have different abilities regarding IDE translation mode.

UNIX operating systems (as currently implemented) do not support either LBA or
ECHS and must utilise the standard CHS method. UNIX can support drives larger
than 528MB, but does so in its own way.

OS/2 2.1 and OS/2 Warp can support LBA, ECHS or standard CHS methods. Note
that LBA support may require a switch setting on an OS/2 driver in order to operate
in that mode.

OS/2 2.0 & Novel NetWare can support either ECHS or standard CHS methods. In
order to use LBA with NetWare a driver that supports current parameters must be
used.OS/2 2.0 does not support LBA.

DOS & Windows can use LBA, ECHS or standard CHS methods. The '32-bit Disk
Access' driver built into Windows WDCTRL.386 can only be used with the standard
CHS method, To use either LBA or ECHS method and '32-bit Disk Access' an
alternative .386 driver must be installed, this combination will also provide the best
performance. If this driver is not installed and the drive fitted to the system supports
Type F DMA on the ISA interface or Mode 3 on the PCI interface then higher
performance will be achieved by NOT using '32-bit Disk Access'.

Power Supply Connector

When used with an ATX-compliant power supply that supports remote power on/off,
the motherboard can turn off the system power through software control.

To enable soft-off control in software, advanced power management must be
enabled in the Setup program and in the operating system. When the system BIOS
receives the correct APM command from the operating system, the BIOS turns off
power to the computer.

With soft-off enabled, if power to the computer is interrupted by a power outage or a
disconnected power cord, when power resumes, the computer returns to the power
state it was in before power was interrupted (on or off).

Reliability Prediction Procedure, TR-NWT-000332, Issue 4, September 1991.
The MTBF prediction is for:

• Redesigning the motherboard for alternate components if failure rates

exceed reliability expectations.

• Estimating repair rates and spare parts requirements.

MTBF data is calculated from predicted data @ 55 °C.
The MTBF prediction for the motherboard is 30,000 – 50,000 hours.

Chapter 6 Glossary

BIOS

This is software stored on a chip and consists of the instructions necessary for the
computer to function. The System BIOS contains the instructions for the keyboard,
disk drives etc., and the VGA BIOS controls the VGA graphics card.

CPU

Central Processing Unit. This is the main piece of equipment on the motherboard.
The CPU processes data, tells memory what to store and the video card what to
display.

Default
The configuration of the system when it is switched on, or the standard settings
before any changes are made.

DIMM

Dual In-Line Memory Module, a type of memory module used for the systems main
memory.

Driver

A piece of software which is used by application software to control some special
features. Each graphics board and printer requires its own driver.

D-Type

A common type of connector used for connecting printers, serial ports, game port,
and many other types of interface.

DRAM

Dynamic Ram used for main system memory, providing a moderately fast but cheap
storage solution.

FDC

Floppy Disk Controller - the interface for connecting floppy disk drives to the
computer.

Hercules

A monochrome graphics video mode which first appeared in the Hercules graphics
card. Provides a resolution of 720 by 348 pixels.

IDE

Integrated Drive Electronics - currently the most popular type of interface for hard
disk drives. Much of the circuitry previously required on hard disk controller cards is
now integrated on the hard disk itself.

Interface

The electronics providing a connection between two pieces of equipment. For
example, a printer interface connects a computer to a printer.

Interlace

The mode the graphics card uses to refresh a monitor screen. When the graphics is
in interlace mode, the frequency of the display update is lower than in non-interlace
mode. This causes a slight flicker, so generally non-interlaced mode is better if the
monitor supports it.

L.E.D.

Light Emitting Diode - a light which indicates activity - for example hard disk access.

PCI

Peripheral Component Interface. It became apparent to manufacturers that the
8MHz AT ISA BUS on the standard PC was just not fast enough for today's
applications, and so PCI was invented. It is a high speed data bus that carries
information to and from components - known as 'Local Bus'.

RAM

Random Access Memory - the memory used by the computer for running programs
and storing data.

ROM

Read Only Memory - a memory chip which doesn't lose its data when the system is
switched off. It is used to store the System BIOS and VGA BIOS instructions. It is
slower than RAM.

Shadow Memory

The BIOS is normally stored in ROM. On certain systems it can be copied to RAM on
power up to make it go faster. This RAM is known as shadow memory. The System
BIOS is responsible for this copying.

Super VGA

Additional screen modes and capabilities provided over and above the standard
VGA defined by IBM.

VGA

Video Graphics Array - the graphics standard defined by IBM and provided on IBM's
PS/2 machines.
