Hardware Setup

Chapter 2

Hardware Setup

If your mainboard has already been installed in your computer you may still need
to refer to this chapter if you plan to upgrade your system's hardware.

Be sure to disconnect the power cable from the power source before performing
any work on your mainboard, i. e. installing a CPU, memory module,
changing a jumper setting, etc. Not doing so may result in electrical shock!

2-1 Introduction to Jumpers

Jumpers are used to select between various operating modes. A jumper consists of
a row of gold colored pins that protrude from the surface of the mainboard. It is
important not to confuse jumpers with connectors or headers.

Putting jumper caps on anything that is not a jumper may result in damaging
your mainboard. Please refer to Section 1-3, Mainboard Layout, for the
location of jumpers on your mainboard.

As indicated in Figure 2-1 below, a cap is used to cover the pins of a jumper, resulting
in shorting those pins that it covers. If the cap is removed from the top of the pins,
the jumper is left "open." The number 1 shown both in the diagram below and in
all multiple pin jumper and header diagrams in this manual indicates the pin
designated with the number 1. The numbering of the remaining pins follows in
sequence.

2-2 Installing an AMD Athlon Processor in Socket A

1. The Socket 462, designed for AMD Athlon processors, has been incorporated as a
standard mainboard specification.To insert your CPU into Socket A please do the
following:

2. Locate a small dot marked on the top surface of the CPU close to one if it's

corners. The same corner will also be cut off, leaving a noticeable notch in the
CPU's corner. These markings indicate Pin 1 of the CPU.

3. Pull up the lever of Socket 462 so that it is perpendicular with the surface of

the mainboard. Gently insert the CPU with Pin 1 at the same corner of Socket 462
that contains the end of the lever. Allow the weight of the CPU to push itself into
place. Do not apply extra pressure as doing so may result in damaging your CPU.
Snap the lever back into place.

Installing a heat sink with cooling fan is necessary for proper heat
dissipation from your CPU. Failing to install these items may result in
overheating and possible burnout of your CPU.

2-3 Plug and Play CPU Configuration

This board support plug and play CPU configuration, if you install a CPU on
this mainboard, the board will automatically detect and set the CPU system bus
frequency speed. It is no longer necessary to make many jumper settings as on
conventional mainboards.

CPU Host/PCI Clock Timing

1. After installing all your hardware into your PC system, turn on your system's
power. Enter the CMOS Setup Utility by pressing the Delete key when your
BIOS identification screen appears.

2. Move the cursor to Frequency/Voltage Control Setup menu and press Enter.
Select the CPU Host/PCI Clock Setup commands at the left hand side of the
BIOS screen.

3. Select the CPU Host/PCI Clock value according to the speed of your CPU
processor and PCI bus. (See section 3-8)

4. Press Esc to return to the CMOS Setup Utility, press F10 to Save and Exit
Setup and choose to confirm. The system will automatically reboot and during
start-up you will see the correct CPU type shown on the screen.

2-4 Connector and Jumper Settings

Connectors are used to link the system board with other parts of the system, including
the power supply, the keyboard, and the various controllers on the front panel of
the system case.

The power supply connector is the last connection to be made while installing
a mainboard. Before connecting the power supply, please make sure it is not
connected to the power source.

ATX Power Supply Connector (CN6)

The power cord leading from the system's power
supply to the external power source must be the
very last part connected when assembling a system.

The ATX power supply provides a single 20-pin
connector interface which incorporates standard +/

-5V, +/-12V, optional 3.3V and Soft-power signals.
The Soft-power signal, a 5V trickle supply is
continuously supplied when AC power is
available. When the system is in the Soft-Off
mode, this trickle supply maintains the system in
it's minimum power state.

Software Power-Off Control

This mainboard can be powered down using the Windows 95/98 Software Power-Off
function. To power down your computer, click the START button on the Windows
95 task bar. Select "Shut Down The Computer" and the system turns off. The message
"It is now safe to turn off your computer" will not be shown when using this function.

Front Panel Connector Set (CN12) A through G

A. Over-ride Power Button Connector

The power button on the ATX chassis can be used
as a normal power switch as well as a device to
activate Advanced Power Management Suspend
mode. This mode is used for saving electricity
when the computer is not in use for long periods of
time. The Soft-OFF by PWR-BTTN function in
BIOS's Power Management Setup menu must be set
to "Delay 4 Sec." to activate this function. (See
section 3-5)

When the Soft-OFF by PWR-BTTN function is
enabled, pushing the power button rapidly will
switch the system to Suspend mode. Any occurrence
of external activities such as pressing a key on the
keyboard or moving the mouse will bring the
system back to Full-On. Pushing the button while
in Full-On mode for more than 4 seconds will
switch the system completely off. See Over-ride
Power Button Operation diagram.

C. Green Switch/Green LED Connector

Some ATX cases provide a Green switch which
is used to put the system in Suspend mode. In
Suspend mode, the power supply to the system
is reduced to a trickle, the CPU clock is stopped,
and the CPU core is in it's minimum power state.
The system is waken up whenever the keyboard
or mouse is touched. The system resumes in
different ways as defined by Power Management
Setup screen in BIOS.

D. System Reset Switch Connector

This connector should be connected to the reset
switch on the front panel of the system case. The
reset switch allows you to restart the system
without turning the power off.

system reads/writes to the IDE devices.

G. Turbo LED Connector

This mainboard does not have a Turbo/De-turbo
speed modes. So the turbo LED will always light .

Poly-fuse Over Current Protection

The poly-fuse protects the system from dangerous voltages the system might be
exposed to via the keyboard or USB connectors. In case of such exposure, the poly­fuse will immediately be disconnected from the circuit, just like a normal fuse. After
being disconnected for a certain period of time, the poly-fuse will return to its normal
state, after which the keyboard or USB can function properly again. Unlike
conventional fuses, the poly-fuse does not have to be replaced, relieving the user
wasted time and inconvenience.

Hard Disk Setup (Primary/Secondary; Master/Slave)

This category identifies up to four IDE hard disk drives that have been installed
in the computer. This section does not show information on other IDE devices such
as CD-ROM drives or other hard drive types such as SCSI drives.

22

Award BIOS Setup Program

Type (Auto/User/None): Use the fields under the Type column to determine the
method you will use to configure the IDE devices. If you choose Auto, BIOS will
automatically detect and make optimal settings for most IDE hard drives.

The mainboard manufacturer recommends that you choose Auto for all
drives.

Choose User to define your own drive type manually. You must enter values
indicated in the table below into each drive parameter field. This information should
be included in the documentation from your hard disk vendor or system manufacturer:

TYPE Setting method

CYLS Number of cylinders

HEAD Number of heads

PRECOMP Write precompensation cylinder

LANDZ Landing zone

SECTOR Number of sectors

MODE Mode type

Table 3-1 Hard Disk Drive Parameters

Cyls/Head/Sector: The number of Cylinders, Heads, and Sectors can usually be found

written on the top of the hard disk. If you have a relatively new hard drive, entering
this information alone is usually sufficient for normal hard disk operation. The hard
disk will not work properly if you enter improper information for these categories.

Precomp: Older hard drives (i.e., MFM or RLL drives) have the same number of
sectors per track at the innermost tracks as at the outermost tracks. Thus, the data
density at the innermost tracks is higher and the bits are lying closer together. Even
though the physical size of a sector gets progressively smaller as the track diameter
diminishes, each sector must still hold 512 bytes. Write precompensation circuitry
compensates for the difference in sector size by boosting the write current for inner
track sectors.

Landz: This defines the address of the landing zone and is only used for older hard
drives which do not have an auto-parking feature.

Mode: If the Type value is not None for any device, you must set the Mode value
for that device. There are four different Mode values: Auto, Normal, Large, and
LBA.

* Auto - BIOS detects and enters the IDE drive type during boot up.

* Normal - for IDE drives that meet the old IDE specification which support

a maximum capacity of 528MB (1024 cylinders, 16 heads, and 63 sectors).

23

User's Manual

* Large - for IDE drives that do not support LBA and have more than 1024
cylinders. Try this setting if your hard disk does not operate properly with
the LBA setting. Large mode is not supported by all operating systems, i.e.,
only certain versions of DOS support large mode.

* LBA - (Large/Logical Block Addressing) With LBA, the IDE controller
transforms the data address described by sector, head, and cylinder number
into a physical block address, significantly improving data transfer rates. This
mode is for drives with greater than 1024 cylinders and between 528MB and

8.4GB in size. This protocol is the current common standard.

Choose None for Type if there are no IDE HDD devices in your system.

You can use the IDE HDD Auto Detection function to auto detect your hard

!

drive parameters. Using this function will automatically insert the parameters
discussed under Hard Disk Setup and will indicate User for the Field value.
Please see Section 3-9 for more information.

Floppy Disk Drives

Choose the memory capacity and disk size that corresponds with that of your floppy
disk drive(s).

Video

Select the type of video adapter present in your system. You can ignore this setting
if you are using a VGA monitor since VGA BIOS automatically configures this setting.

Halt

When the system is powered on, BIOS performs a series of diagnosis tests called
POST (Power On Self Test). This function stops the computer if BIOS detects a
hardware error. You can tell BIOS to halt on all errors, no errors, or not to halt on
specific errors.

A. Anti-Virus Protection

Trend ChipAway Virus

Trend ChipAway Virus is a code incorporated in the mainboard's BIOS firmware.
During the boot-up sequence, BIOS loads before loading of the partition table
or boot sector. ChipAway Virus loads with BIOS and is able to detect boot­up viruses before they have a chance to infect the hard drive. ChipAway Virus
employs rule-based logic that doesn't look for specific viruses but rather detects
patterns found in every virus, eliminating the need to perform periodical version
updates after new viruses have been found.

B. Cache Control

CPU Internal Cache/External Cache

Cache memory is much faster than conventional DRAM system memory. These
fields allow you to enable or disable the CPUs Level 1 built-in cache and Level
2 external cache. Both settings are left enabled to significantly increase the
performance of your computer.

C. Boot Up Features

After turning on the system, BIOS will perform a series of device initialization
and diagnostic tests discussed below.

Quick Power On Self Test (POST)

Enable this function to reduce the amount of time required to run the POST (Power
On Self Test). BIOS saves time by skipping some items during POST. It is
recommended that you disable this setting. Discovering a problem during boot
up is better than loosing data during your work.

First/Second/Third/Boot Other Device

This option sets the sequence of drives BIOS attempts to boot from after POST
completes. BIOS will search these drives for an operating system.

Swap Floppy Drive

Enabling this function will swap the floppy drive assignment so that drive A
will function as drive B, and drive B will function as drive A. Note that the
boot sequence assignment mentioned directly above does not include booting
from floppy drive B. This function is useful if floppy drives B and A are of
a different format and you want to boot from floppy drive B.

Boot up Floppy Seek

During POST, BIOS will determine if the installed floppy disk drive has 40 or
80 tracks. A 360K drive has 40 tracks and 720K, 1.2M and 1.44M drives have
80 tracks. All modern floppy disk drives have 80 tracks.

Boot Up NumLock Status

This function defines the keyboard's number pad as number keys or arrow keys.

D. Keyboard Interface

Typematic Rate Setting

When enabled, you can set the following two typematic control items. When
disabled, keystrokes are determined arbitrarily by the keyboard controller in your
system.

Typematic Rate (Chars/Sec)

The typematic rate sets the rate at which characters on the screen repeat when
a key is pressed and held down.

26

Award BIOS Setup Program

Typematic Delay (Msec)

The typematic delay sets how long after you press a key that a character begins
repeating.

E. Security Option

The Supervisor and/or User Password functions shown in Figure 3-1 must be set
to take advantage of this function. See Section 3-11 for password setting
information. When the Security Option is set to System, a password must be
entered to boot the system or enter the BIOS setup program. When the Security
Option is set to Setup, a password is required to enter the BIOS setup program.

F. OS Select (For DRAM >64MB)

If your system's DRAM is larger than 64MB and you are running OS/2 , select
OS/2 as the item value. Otherwise, set the item value to Non-OS/2 for all other
operating systems.

G. Shadow Memory

Software such as system BIOS, video BIOS, SCSI BIOS, etc that resides in ROM
(Read Only Memory) chips is called firmware. Shadowing of firmware occurs
when BIOS is copied to RAM address C0000h through DFFFFh. Video BIOS
loads into the C0000-C7FFF memory area when video shadowing is enabled.
If an expansion peripheral in your system contains ROM-based firmware, you
need to know the address range the ROM occupies to shadow it into the correct
area of RAM.

Shadowing improves the firmware's performance because the firmware can be read
by the CPU through the 16- or 32-bit DRAM bus as opposed to the 8-bit XT
bus. However, shadowing also results in reducing the amount of high memory
(640 KB to 1 MB) for loading device drivers. Shadowing is used mostly for
ROM chips on ISA cards and not for PCI cards. Shadowing and playing games
at the same time may result in system instability as some games access the RAM
memory area being shadowed.

Figure 3-4 Chipset Features Setup Screen

All of the above settings have been determined by the mainboard manufacturer

and should not be changed unless you are absolutely sure of what you are

doing. Explanation of the DRAM timing and chipset features setup is lengthy,

highly technical and beyond the scope of this manual. Below are abbreviated

descriptions of the functions in this setup menu. You can look on the world

wide web for helpful chipset and RAM configuration information including

AWARD's web site at http://www.award.com.

A. SDRAM Cycle Length

When synchronous DRAM is installed, the number of the clock cycles of CAS
latency depends on the DRAM timing. Do not reset this setting from the default

value specified by the system designer.

28

Award BIOS Setup Program

B. Memory Hole

Enabling this function will reserve the memory address space between 15MB
and 16MB for ISA expansion cards. However, enabling this function will result
in not allowing the system to have access to memory above 16MB. Please note
that some expansion cards require this setting to be enabled. The default setting
is Disabled. If Auto Configuration is enabled, you must set the DRAM timing
function to 60ns or 70ns, depending on the type of DRAM you install.

C. System BIOS Cacheable

Enabling this function allows caching of the system BIOS ROM at F0000h­FFFFFh, resulting in better system performance. However, if any program writes
to this memory area, a system error may result. Caching the system BIOS results
in better performance than shadowing the system BIOS as discussed in Section
3-2.

D. Video RAM Cacheable

Enabling this function will allows caching of the video RAM, resulting in
better system performance. However, if any programs write to this memory
area, a system error may occur.

E. AGP Aperture Size

This function determines the amount of system memory that is given to the AGP
card. Options range from 4MB to 128MB. This is a dynamic memory allotment
in that the AGP card will only use the amount of memory that it needs. The
remaining memory not in use will be available for the system to use. For example,
if 16MB is alloted to the AGP card and the card only needs 8MB, the remaining
8MB will be available for system use.

F. AGP-4X Mode

Enable this setting to utilize the4X mode (twice as fast as2X) offered by advanced
AGP cards. Your VGA card must support 4X mode in order to take advantage
of the faster speed.

G. Flash BIOS Protection

The mainboard manufacturer developed BIOS protection technology that protects
the System BIOS from accidental corruption by unauthorized users or computer
viruses. When enabled, the BIOS data cannot be changed when attempting to
update BIOS with the the FLASH utility. When disabled, the BIOS data can
be updated by using the FLASH utility.

pin 2-3 as discussed in Section 2-4 of this manual to enable this function.

J. CPU to PCI Write Buffer

When Enabled, CPU to the PCI bus are buffered, to compensate for the speed
differences between the CPU and the PCI bus.

K. PCI Delay Transaction

The chipset has an embedded 32-bit posted write buffer to support delay
transactions cycles. Select Enabled to support compliance with PCI specification
version 2.1.

33

User's Manual

C. Video Off Option

This setting allow you to selects the power-saving modes during which the
monitor goes blank:

D. Video Off Method

This function serves as both a screen saver and power saver for monitors.
See the next function, Video Off After, for setting the video timer.

Blank - BIOS will only blank the monitor's screen. The electricity saved in
this mode is negligible and this function is only used as a screen saver to
prevent screen damage while the screen is on but not in use.
V/H SYNC+Blank - The system turns off the vertical and horizontal synchro­nization ports, writes blanks to the VGA buffer and the monitor's electron
gun turns off. This function requires a monitor with Green features in order
to take advantage of the power saving function. If you enable this function
and

do not have a Green monitor, the result will be the same as if you had

selected Blank. This function serves as both a screen saver and an electricity
saver.

DPMS Supported - Select this option if your video card supports the Display
Power Management Signaling (DPMS) standard (i.e., you have a monitor that
supports Green features). Use software supplied by your video subsystem to
set video power management options.

E. Modem Use IRQ

If your computer has an modem, use this function to tell BIOS which IRQ is being
occupied by the modem card. When the system is in Green mode, the modem
requires an IRQ assignment to wake up the system and perform tasks. This
assignment is compliant with the APM 1.2 specification and is to be used in
coordination with APM 1.2 compliant operating systems.

F. Soft-Off by PWR-BTTN

When set to Delay 4 Sec., this function allows the power button to put the system
in Suspend, a power saving mode. See Section 2-4 for operation instructions
of the override power button operation which puts the system in Suspend mode.
When set to Instant-Off the Soft-Off by PWR-BTTN function is disabled and the
computer turns completely off when the power button is pressed.

3-11 Supervisor Password & User Password Setting

There are four different variables that control password settings. The first two are
located under the Security Option function in BIOS Features Setup Menu (Figure
3-1). When the Security Option function is set to Setup, a password is required to
enter BIOS and change BIOS settings. When the Security Option function is set
to System, a password is required to enter both BIOS and the computer's operating
system (for example Windows 98) found on the boot drive. This is shown in Figures
3-12 and 3-13.

The third and fourth variables are user password and supervisor password selected
in BIOS (Figure 3-1). The main purpose of separating user and supervisor is to allow
only the supervisor to have control over the settings in BIOS. The user, on the other
hand, is only allowed to access the computer's operating system and change the user
password in BIOS (See Figure 3-13 ). Note that when there is no supervisor password
set, the user password controls access to all BIOS settings (See Figure 3-12 below).

6 Speakers System(Optional)

The CMedia 8738 Audio subsystem provides 3 wave channels (front/rear/
center+bass), known as the 6 speakers system. When games or application
programs via DirectSoundR 3D or A3DR interface locate the sound sources to
the listener's back, the two rear speakers will work to enhance the rear audio
positional effect, so as to complement the insufficiency of using only two front
speakers to emulate the audio effect. The following is the hardware installation
and the software setups:

User's Manual

Installation

1. Connect the front pair speakers to the Line-out jack of the audio adapter, and
then connect rear pair speakers to Line-in/Rear jack of the audio adapter. The
original Line-in can be moved to Aux-in.

2. Install the audio driver and Audio Rack application software(see chapter 4).

3. There is a multi speakers option in the volume control of the mixer, and when
you enable this option, it means the rear speakers are connected to Line-in/Rear
jack. When Line-in/Rear jack is connected to other external Line-in sources,
please DO NOT enable this option in order to avoid hardware conflicts. Regarding
rear speaker option, you can turn ON or turn OFF the output of the back speakers,
and adjust the volume, to have the rear/front speakers have the same volume.
