Hardware Setup

+D=FJAH

0=H@M=HA5AJKF

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.

This mainboard is electrostatic sensitive. Do not thouch without wearing
proper safety gudget and make sure to disconnect the power cable from the
power source before performing any work on your mainboard . Not doing

so may result in electrical shock!

2-1 Installing a CPU Processor in Socket A

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

1. 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.

2. 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 burn-out of your CPU.

2-2 Setting Your CPU's Parameter

Frequency Configuration

If you install a CPU on this mainboard, you must set JP20 for CPU Bus Frequency.
You may also select (fine tune) the external clock frequency according to your
processor SW1 (See Section 2-4).

* CPU Speed = Frequency ratio x External clock (System) Frequency

You do not need to make voltage settings because SeePU automatically sets
your CPU voltage.

Chapter 2

2-3 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 (PW1)

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 theWindows 95 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.

Power-On By Modem

While in Soft-off state, if an external modem ring-up signal occurs, the system wakes up
and can be remotely accessed. You may enable this function in BIOS's Power
Management Setup menu. (See section 3-5)

Blinking LED in Suspend Mode

While in Suspend mode, the LED light on the front panel of your computer will flash.
Suspend mode is entered by pressing the Override Power Button, pushing the Green
button on your ATX case, or enabling the Power Management and Suspend Mode
options in BIOS's Power Management menu. (See section 3-5)

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.

Hardware Setup

Front Panel Connector Set (CN1) A through F

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.

When the Soft-OFF by PWR-BTTN function is enabled,
pushing the power button rapidly will switch the system to

Over-ride Power Button

B. Power Indicator LED Connector

The power indicator LED shows the system's power status. It is important to
pay attention to the correct cables and pin orientation (i.e., not to reverse the order
of these two connectors.)

Suspend mode. Any occurence 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 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 woken 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.

E. Speaker Connector

This 4-pin connector connects to the case-mounted speaker

F. IDE Activity LED Connector

The IDE activity LED lights up whenever the system reads/writes to the IDE
devices.

A. Anti-Virus Protection

The Anti-Virus Protection 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. Anti-Virus Protection loads with BIOS and is able to detect boot­up viruses before they have a chance to infect the hard drive. Anti-Virus Protection
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.

15

User's Manual

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. DRAM Clock/Drive Control

DRAM Timing

The function allows you to enable or disable the DRAM timing by SPD. When
Disabled, you can select the DRAM Clock, SDRAM Cycle Length and Bank
Interleave configuration.

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.

17

User's Manual

B. AGP & P2P Bridge Control

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.

AGP 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.

C. CPU & PCI Bus Control

PCI1/PCI2 Master 0 WS Write

When Enabled, writes to the PCI bus are executed with zero wait states.

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.

D. 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.

E. System BIOS Cacheable

Enabling this function allows caching of the system BIOS ROM at F0000h-FFFFFh,
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.

18

Award BIOS Setup Program

F. 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.

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 FLASH utility. When disabled, the BIOS data can be updated
by using the FLASH utility.

by entering increasingly deep power saving modes as shown by the diagram below.

22

Award BIOS Setup Program

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 a power 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-BTN

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-BTN 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.

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. Note that when there is no supervisor password set, the user
password controls access to all BIOS settings.

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.
