Hardware SetupHardware 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 a PGA type CPU in a ZIF Socket

The Intel Socket 7, designed for the Pentium processor, has been incorporated as
a standard mainboard specification and is compatible with AMD and Cyrix CPUs. To
insert your CPU into Socket 7 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. See Figure 2-2.

Figure 2-2 The markings on top of a CPU

2. Pull up the lever of Socket 7 so that it is perpendicular with the surface of the
mainboard. Gently insert the CPU with Pin 1 at the same corner of Socket 7 that
contains the end of the lever. Allow the 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. See Figure 2-3.

Installing a heat sink and cooling fan on top of your CPU is necessary for
proper heat dissipation. Failing to install these items may result in overheating
and possible burn-out of your CPU.

Overclocking

Operating a CPU at a higher frequency than its specification allows is called overclocking.
If the CPU frequency is set at a higher frequency than its specification allows, it may
or may not run at that freqency, depending on the quality of your CPU and the extent
to which the frequency has been overset. The mainboard manufacturer highly
discourages overclocking as it may result in data loss, CPU burn-out, system failure,
etc.

Many processors are frequency locked processors and are not able to perform
overclocking. Regardless of whether the processor is a frequency locked, overclocking
may cause some processors to hang when turning on the system. When the processor
hangs, the screen remains blank and the system does not boot. To solve this problem,
do the following:

1. Turn off the computer and then press the Home key on your keyboard

2. Turn on your computer, wait for five seconds and then release the Home key.

(Pressing the Home key allows the computer to boot at a low system speed.
For example, 66MHz external clock CPUs boot-up at 133MHz.)

3. Enter BIOS and reconfigure your CPU parameters as described in this section.

Voltage ConfigurationVoltage Configuration

Voltage Configuration

Voltage ConfigurationVoltage Configuration

There are two major processor types in general
use--single and dual voltage processors. Most
single voltage processors such as Pentium,
AMD-K5, and Cyrix 6x86 processors use a
single voltage value of 3.5v for both core and
I/O voltage settings. Most dual voltage
processors such as Pentium processors with
MMX technology and Cyrix 6x86L
processors use a dual voltage value of 2.8v
for core and 3.3v for I/O voltage settings. To
make the voltage setting for single and dual
voltage processors, simply set JP16~20
according to the table on the next page. The
voltage range supported by this mainboard
is detailed in Figure 2-5 below.

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 (J8)

This mainboard requires a power supply of at least 200

1

watts. 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 Soft­Off 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.

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

PRECOM P Write precompensation cylinder

LANDZ Landing zone

SECTOR Number of sectors

MODE Mo de 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 bootup.

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 diagnotic 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 boot-up
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.

25

User's Manual

CPU L2 Cache ECC Checking

Enable this function to perform ECC (Error Check and Correct) on the CPU's L2
SRAM. ECC detects and corrects single-bit errors while it only detects double
bit errors. Certain SDRAM modules also have ECC capability. For more
information on SDRAM, see section 2-5. If you are using a 333MHz or higher
CPU, this function must be enabled.

C. Boot Up Features

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

Boot From LAN First

Enabling this function the BIOS will attempts to boot from a LAN boot image before
it attempts to boot from a local storage device.

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 bootup
is better than loosing data during your work.

Boot Sequence

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 inlcude 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 numberpad as number keys or arrow keys.

26

Award BIOS Setup Program

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.

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 3-8 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. PCI/VGA Palette Snoop

Some non-standard VGA cards or MPEG video cards may not show colors properly.
Setting this function to Enabled can correct this problem.

G. 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.

H. 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.

A. SDRAM CAS Latency

When set to Auto this feature will use "default" option to read CAS Latency from
the SPD of the DIMMs, with this mechanism the user's need only to reboot the
system to get a set of proper value of CAS Latency.

B. AGP Aperture Size (MB)

This function determines the amount of system memory that is given to the AGP
card. Options range from 4MB to 256MB. 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 are alloted to the AGP card and the card only needs 8MB, the remaining
8MB will be available for system use.

C. 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.

D. Video BIOS Cacheable

Enabling this function allows caching of the video BIOS ROM at C0000h-C7FFFh,
resulting in better video performance. However, if any program writes to this
memory area, a system error may result. Caching the video BIOS results in better
performance than shadowing the video BIOS as discussed in Section 3-2.

E. Memory Hole at 15M-16M

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.

F. PCI Delayed 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.

G. Spectrum Spread

When Enabled this function will cause lower EMI by spreading the system
frequency spectrum. While this function decreases EMI, system stability may
be slightly compromised. Choosing Smart Clock will turn off the AGP, PCI, and
SDRAM clocks when not in use. Smart Clock does not perform a spectum
spreading function.

H. 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.

To Pass the Windows 95 SCT testing, this item should be disabled.

Please note that when disabling this setting, the system BIOS is vulnerable
by intrusion of computer viruses. It is recommended to disable this setting
only temporarily while updating your system's BIOS.

B. Power Management

Power management allows the computer to save electricity when it is not in use
by entering increasingly deep power saving modes as shown by the diagram below.

Figure 3-6 Power Saving Mode Flow Chart

The computer runs in Normal operation mode until the Doze timer expires, at which
point the computer enters Doze mode. If no external activity occurs, the computer
will go into Standby and Suspend modes when their respective timers expire. If
external activity occurs, the computer will wake up from Power Management and
return to Normal mode. To activate the function, set Power Management to

Maximum Saving, User Define, or Minimum Saving described below. For a
description of the power saving modes (Doze, Standby, and Suspend) see their
descriptions below.

Disabled - Turns off the Power Management functions.
Max. Saving - All timers are set at the minimum value of one minute to

maximize power saving.
Min. Saving - All timers are set at the maximum value of one hour for

minimal power saving.
User Define - User can configure the timer to a desired time according to the

values available.

@

Note that enabling the Power Management function will result in enabling the
HDD Power Down function (Max Saving = 15 min, Min Saving = 1 min). The
HDD Power Down function is not part of the Power Management scheme as
indicated in Figure 3-6 Refer to the Standby Mode, Suspend Mode, and HDD
Power Down descriptions below for more informaiton on hard drive power
management.

This setting determines when the monitor enters power saving mode. As the
function name indicates, the monitor enters the power saving mode after the chosen
event expires. The Power Management function must be enabled to use this
function.

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 your video
subsystem to set video power management options.

E. Switch Function

When this option is set to Break/Wake, the system enters the suspend mode;
press the power button again to return to full power.

F. 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.

G. HDD Off After

After the selected period of drive inactivity, the hard disk drive powers down
while all other devices remain active. Selecting Suspend tells the drive to power
down immediately.

H. Doze Mode

The Power Management function must not be set to disabled to enable this
function. If no interrupts have occured and the Doze timer expires, system will
enter Doze mode. In Doze mode, the CPU clock runs at a lower speed while
all other devices operate normaly.

Power saving modes achieved in lower power saving states will either be

@

maintained or enter higher power saving modes when switching to higher
power saving states. For example, the CPU clock will not switch back to
normal in Standby mode. It will maintain a decreased rate in Standby Mode
and turn off in Suspend Mode.

User's Manual

I. Standby Mode

The Power Management function must not be set to disabled to enable this
function. If the system runs in Doze mode and the Standby timer expires, the
system will enter Standby mode. In Standby mode, the hard disk drive and the
monitor shut off while all other devices still operate at full speed. Note that the
Video Off and HDD Power Down functions in Figure 3-5 provide the same power
saving options found in Standby mode. The priority for determining which
function controls power saving for the monitor and hard drive is determined by
which timer expires first.

J. Suspend Mode

The Power Management function must not be set to disabled to enable this
function. If the system runs in Standby mode and the Suspend timer expires, all
devices regulated by power management will shut off and the CPU speed will be
0 MHz.

K. PM Events

The HDD/COM/LPT/VGA Acitvity and IRQ[3-7,9-15], NMI. When Enabled any
activity from one of the listed system peripheral or devices, IRQs wakes up the
system.

@

A power-management (PM) event awakens the system from, or resets activity
timers for, Suspend mode. You can disable monitoring of common interrupt
requests so they do not generate PM events.

L. IRQ8 Break Suspend

Enabling this setting turns the monitoring of IRQ8 (the Real Time Clock) On so
it does not awaken the system from Suspend mode.

M. Power Button Over Ride

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 over-ride power button operation wich puts the system in Suspend mode.
When set to Instant-Off the Power Button Over Ride function is disabled and
the computer turns completely off when the power button is pressed.

N. Wake Up On LAN

Enable this selection to use the Wake Up On LAN function discussed in Section
2-4 of this manual.

Award BIOS Setup Program

O. Power On By Keyboard

Set to Disabled to control your computer's power by the button on your system
case. Set this function to Any Key to turn on the computer by touching any
key on the keyboard. If you set this function to Hot Key or Password you must
designate the keystrokes that will turn on the computer. Note that the power button
is always able to turn on the computer regardless of how this function is set.

If you have forgotten your passord, you must remove the power cable from

@

the ATX power supply connector and clear the CMOS data as discussed
in Section 2-4 to clear the password.

P. Power On By Modem

When enabled, a modem that receives a call will wake up the system from
soft off and green mode. You should connect the modem to the COM port
and turn on the resume event in green mode.

Q. Power On By Alarm

When enabled, this setting allows the system to turn back on at a designated
time of the month. User must designate date of month and time of day.
This function is only available when using an ATX power supply and the Software
Power-Off function to turn off the computer. See the Software Power-Off feature
in Section 2-4 of this manual for instructions.

A. PnP OS Installed

If you want to install a PnP compatible OS (such as Windows 95) set to Yes.

B. Resources Controlled By

When set to Manual the system BIOS will not refer to the ESCD for IRQ & DMA
information. Instead, it will refer to the items in the setup menu for assigning IRQ
& DMA. When set to Auto the system BIOS will refer to the ESCD for all legacy
information.

36

ESCD(Extended System Configuration Data) provides a detailed format of
the configuration data structures stored in flash memory. Each data structure
defines the resources used by a device or a card in the system. This includes
legacy and PCI/ISA PnP devices.

Award BIOS Setup Program

C. Reset Configuration Data

When enabled the system BIOS will clear/reset the ESCD during POST. After
clearing the ESCD, the BIOS will then change this item's value to Disabled.
Otherwise, the ESCD data will become useless.

D. IRQ#/DMA# assign to

When resources are controlled manually, you can assign each system interrupt
& DMA channel for "Legacy ISA" or "PCI/ISA PnP" card used.

While using Legacy ISA Card(non-PnP ISA card), please set it's necessary
corresponding resources (INT#, DMA#) from "PCI/ISA PnP" to "Legacy
ISA."

@ All ISA non-PnP devices are legacy devices that select resources (I/O Addr.,

INT# or DMA#) by using hardware jumpers.

@ IRQ-3/4/7/12/14/15 have been set as default for on board devices (COM2,

COM1, Printer port, PS/2 mouse, IDE1 and IDE2).

E. PCI IRQ Actived By

Leave the IRQ trigger set at Level unless the PCI device assigned to the interrupt
specifies Edge-triggered interrupts.

F. Assign IRQ For VGA

This function allows BIOS to make an IRQ available to VGA cards. Most current
VGA card models do not require this function to be enabled.

G. FDD IRQ Can Be Free

This function allows user to choose if the FDD IRQ is able to be freed up. The
default setting is Yes and this does not allow the IRQ to be free.

H. Used MEM base addr

This function devotes a space of memory (8K, 16K, 32K, 64K) for any peripheral
that has a high memory requirement. This is also used to designate memory
space for legacy ISA cards. The settings C800~DC00 are used to to designate
point at which the memory will start being used. The default setting is N/A
(disabled.)

A. Internal PCI/IDE

The chipset contains a PCI IDE interface that supports two IDE channels: Primary
(IRQ 14) and Secondary (IRQ 15). Each channel supports two IDE devices, so
the system is capable of supporting a total of four IDE devices. Select Primary,
Secondary, or Both to activate chipset IDE interface(s) installed on your system
board.

B. IDE Primary/Secondary Master/Slave PIO

The four IDE PIO (programmed Input/Output) fields let you set a PIO mode (0-

4) for each IDE device that the internal PCI IDE interface supports. Modes 0 through
4 provide successively increased performance. In Auto mode, the system
automatically determines the best mode for each device.

Award BIOS Setup Program

C. Primary/Secondary/Master/Slave UltraDMA

UDMA (Ultra DMA) is a DMA data transfer protocol that utilizes ATA commands
and the ATA bus to allow DMA commands to transfer data at a maximum burst
rate of 66 MB/s. When you select Auto in the four IDE UDMA fields (for each
of up to four IDE devices that the internal PCI IDE interface supports), the system
automatically determines the optimal data transfer rate for each IDE device.

D. IDE Burst Mode

Selecting Enabled reduces latency between each drive read/write cycle, but may
cause instability in IDE subsystems that cannot support such fast performance. If
you are getting disk drive errors, try setting this value to Disabled. This field does
not appear when the Internal PCI/IDE field is Disabled.

E. IDE HDD Block Mode

Block mode is also called block transfer, multiple commands, or multiple sector
read/write. If your IDE hard drive supports block mode (most new drivesdo),
select Enabled for automatic detection of the optimal number of block read/writes
per sector the drive can support.

F. Onboard FDC Controller

Select Enabled if your system has a floppy disk controller (FDC) installed on the
system board and you wish to use it. If you install an add-in FDC or the system has
no floppy drive, select Disabled in this field.

G. Onboard Serial Port 1 and 2

Select a logical COM port name and matching address for the first and second
serial ports. Select an address and corresponding interrupt for the first and second
serial ports.
