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 S.E.C. Processor in Slot 1

To Install the retention mechanism on Slot 1 refer to the figures and instructions
below:

1. Locate the protruding, toothed edge at the end of Slot 1 (Figure 2-3). Find the
complementary indentation at the bottom of the retention mechanism (Figure 2-

2) and insert the retention mechanism onto Slot 1 until the plastic clips at the
bottom of the retention mechanism completely protrude through the bottom of
the mainboard.

2. Insert the retention mechanism pins into the four holes at the base of the retention
mechanism (Figure 2-4), pushing down until they click into place.

3. Insert the Pentium II processor into the retention mechanism. Press evenly and
gently until the snaps on the upper side of the processor have been inserted into
the holes at the top of the retention mechanism. Note that when removing the
processor, these snaps can be clicked into a completely vertical position, leaving
your hands free to stabilize the board. Pull the processor evenly and gently out
of the retention mechanism. Also note that like PCI and ISA slots, Slot 1 has
a divider that prevents backwards insertion of the CPU.

Installing a heat sink and 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.

Overclocking

Operating a CPU at a higher frequency than it's specification allows is called overclocking.
If the CPU frequency is set at a higher frequency than it's 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.

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 (CN10)

This mainboard requires a power supply of at least 200
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 of at least 10mA, 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. Enable this function in BIOS's Power Management
Setup menu. (See section 3-4)

12

Front Panel Connector Set (CN5) 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 button 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 3-4)

When the Soft-OFF by PWR-BTTN function is enabled,
pushing the power button rapidly will switch the system to
Suspend mode. Any occurence of external activity 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.

B. Keyboard Lock & Power Indicator LED
Connector

Plugging this connector into the lock on the front panel
of the system case allows the lock to enable or disable
the keyboard. This function provides limited security
against casual intruders. The power indicator LED shows
the system's power status. It is important to pay attention
to the correct cable and pin orientation (i.e., not to reverse
the order of these two connectors.)

Chapter 2

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 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.

(See section 3-7)

Hardware Setup

CPU/System Cooling Fan Connectors (CN6/CN4)

CN6

These added connectors allow the fan to draw their power
from the mainboard instead of the disk drive connector.
The board's management extension hardware is able to
detect the CPU and system fan speed in rpm (revolutions
per minute). These connectors supports 3-pin cooling

CN4

fans with minimum of 3500 RPM. The wiring and plug may
vary depending on the manufacturer. On standard fans,
the red is positive (+12V), the black is ground, and the
yellow wire is the rotation signal.

(if FAN-II chip is present)

WOL (Wake-on-LAN) Connector (CN1)

Enable the Wake Up On LAN selection in BIOS's Power
Management Menu to use this function. The capability
to remotely manage PCs on a network is a significant
factor in reducing administrative and ownership costs.
Magic Packet technology is designed to give WOL (Wake­on-LAN) capability to the LAN controller. When a PC
capable of receiving wake up command goes to sleep,
the Magic Packet mode in the LAN controller is enabled.
When the LAN controller receives a Magic Packet frame,
the LAN controller will wake up the PC. This header
is used to connect an add-in NIC (Network Interface Card)
which gives WOL capability to the mainboard.

To support this function, a switching power supply
with a minimum of 750mA 5VSB is required.

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. Unlike
conventional fuses, the poly-fuse does not have to be replaced, relieving the user
wasted time and inconvenience.

USB(Universal Serial Bus) Ports

If you want to use a USB keyboard, you must enable the
USB keyboard support function in BIOS's Integrated
Peripherals menu (See Section 3-7). USB is an open
industry standard, providing a simple and inexpensive way
to connect up to 125 devices to a single computer port.
Keyboards, mice, tablets, digitizers, scanners, bar-code
readers, modems, printers and many more can all be used
at the same time.

USB is a dynamically reconfigurable serial bus with an
elementary data rate of 12Mbps. Based on off the shelf,
low cost micro-controller technology, its modular layered
software protocol supports sophisticated devices and
application programs.

This board contains a USB Host controller and includes
a root hub with two USB ports (meets USB Rev 1.0 spec.).
Two USB peripherals or hub devices are able to be
connected.

Compatibility with different USB peripherals is
still being tested.

2-5 Main Memory Configuration

The DRAM memory system consists three banks (bank0, bank1, bank2) and the
memory size ranges from 8~384 MBytes. If you only use one bank it does not matter
which one you use and if you use two or more banks, it does not matter which bank
you install first.

DRAM Specifications

DRAM type: 3.3V, 64/72-bit EDO(Extended Data Output) Synchronous

DRAM
Module size: Single/double-side 8/16/32/64/128 MBytes
DRAM speed: 60-ns or faster for EDO DRAM

10/12ns for Synchronous DRAM
Parity: Either parity or non-parity

The compatibility of 128MB DIMM is still under testing and cannot be 100%
guaranteed.

This mainboard supports 3.3v, unbuffered, 4-clock, SDRAM DIMM only.
Buffered, 5V, or 2-clock SDRAM DIMMs should not be used.

Due to loading anomalies, using DIMM with an 'n x 4' DRAM base on this
mainboard is not recommended. For example, a DIMM that uses sixteen
16Mb x 4 devices should not be used.

ECC DRAM Capability

This mainboard can be configured to support ECC (Error Check and Correct)
function when utilizing parity DIMM modules. To utilize the chipset's ECC

features, you must use a 72-bit DIMM module.These modules are automatically
detected during bootup. However, the user must configure the DRAM Data Integrity
Mode to "ECC" in BIOS's Chipset Features Setup menu to enable the ECC function.
ECC detects double bit errors and detects and corrects single bit memory errors
on the fly without user intervention. Errors may be generated by a defective memory
module, conflicting memory speeds between different banks, DMA, etc.

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.

20

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 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).

21

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. VIRUS PROTECTION

Virus Warning

When Enabled, BIOS activates a warning message to the user when any program
(i.e., a virus) attempts to access the boot sector or hard disk partition table. The
user is able to intervene by running an anti-virus program. This function only
protects the boot sector and not the entire hard drive.

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.

23

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.

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.

Boot Up System Speed

This function determines the CPU speed while in non-protected mode under DOS.
Set to High for regular CPU speed and low for decreased CPU speed. This function
is used for applications such as games that require decreased CPU speed.

D. KEYBOARD INTERFACE

Typematic Rate Setting

When enabled, you can set the following two typematic control items. When

24

Award BIOS Setup Program

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. HDD S.M.A.R.T. Capability

S.M.A.R.T. or Self-Monitoring, Analysis, and Reporting Technology enables a
drive's internal status to be monitored through diagnostic commands. Both your
hard drive must support this capability and this function must be enabled in order
to take advantage of this function. See your hard drive literature for more

information.

I. 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.

25

User's Manual

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.

@If professional engineers or customers would like to make some adjustments

to gain even better system stability and performance, please visit
http://www.award.com to search for helpful information.

A. Auto Configuration

When Auto Configuration is enabled, BIOS autodetects the DRAM module type
(i.e. EDO, FP) and determines the relevant DRAM settings. Note that these DRAM
settings become background print (unchangeable) once the Auto Configuration
is enabled. If Auto Configuration is enabled, you must set the DRAM timing
function to 60ns or 70ns, depeding on the type of DRAM you install.

27

User's Manual

B.

DRAM Data Integrity Mode

BIOS automatically detects the presence of ECC DIMMs (72-bit modules). However,
to take advantage of ECC you must set this function at "ECC." If any non-parity
DIMMs are installed, the memory operates in non-parity mode only and this
function must be set at "Non-ECC."

C. 8-bit I/O Recovery Time & 16-bit I/O Recovery Time

Back-to-back CPU or PCI master originated 8-bit and 16-bit cycles have an arbitrary
delay of at least 3.5 system clock cycles. This category is used to add additional
recovery delay between 8-bit and between 16-bit cycles. This delay takes place
because the PCI bus is much faster than the ISA bus. The options are 1 to 8
and N/A.

D. 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. The default setting is Disabled.

E. Power Failure Recovery

Computers using an ATX power supply do not turn back on after the power source
to the computer unexpectedly fails (i.e. electricity outage). Enabling this setting
will allow the system to always turn back on after a power failure. This is especially
important for computers that must be on 24 hours per day.

F. Spectrum Spread

When Enabled this function will cause lower EMI by spreading the system
frequency spectrum. For normal operation, Disable this function.

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.

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

28

Award BIOS Setup Program

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.

H. Hardware Reset Protect

When this function is enabled, your PC's hardware reset button will not
function. This function is especially useful to prevent accidental resets for
file servers and routers, etc. which should be available 24 hrs/day. When

disabled, your PC's hardware reset button will function normally.

Figure 3-5 Power Management Setup Screen

A. 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

30

Award BIOS Setup Program

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.

B. PM Control by APM

This function allows software other than BIOS to control Power Management
features Enable this function in BIOS and make sure APM (Advanced Power
Management) is present. For example, run the Power utility program located in
the DOS directory, C:\DOS\POWER.EXE to use Power Management features under
DOS. For Windows 3.1x and Windows 95, you need to install Windows with
the APM feature.

C. 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.

31

User's Manual

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.

D. Video Off After

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.

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. 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.

G. 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.

32

Award BIOS Setup Program

H. 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.

I. HDD Power Down

The Power Management function must not be set to disabled to enable this
function. When the HDD idle time has elapsed, BIOS sends a command to the
hard disk to turn off the motor. Set a time between 1 and 15 to indicate time
required to wait before the hard drive enters a power saving mode. Some old
hard drives may not support this function.

J. Throttle Duty Cycle

When the system enters Doze mode, the CPU clock runs only part of the
time. You may select the percent of time that the clock runs.

K. VGA Active Monitor

When Enabled, any video activity restarts the global timer for Standby mode.

L. 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 over-ride power button operation wich 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.

M. 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.

N. 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.

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.

35

User's Manual

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 IDE IRQ Map to

This function allows user to select PC AT (ISA) interrupts or PCI IDE IRQ
mapping.
ISA: BIOS does not designate any IRQ signal to the PCI slot. This is the
default setting.
PCI-SLOT 1-4: User can designate which PCI slot (1-4) the IDE card is inserted
into. This setting is suitable for use with older PCI IDE cards that BIOS is not
able to recognize.
PCI-AUTO: BIOS automatically detects which PCI slot the PCI IDE card is
inserted into.

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 NO and this does not allow the IRQ to be free.

H. Assign IRQ For USB

If USB is employed this function must be Enabled. Otherwise, disable this

Award BIOS Setup Program

I. 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.)

J. Used MEM Length

8K~64K: Determines the amount of memory to be used by ISA cards mentioned
in the Used MEM base addr function above.

3-6 Load Setup Defaults

Load Setup Defaults loads the default system values directly from the CMOS Setup
Utility menu (Figure3-1). If the stored record created by the setup program becomes
corrupted and therefore unusable, these defaults will be loaded automatically when
you turn on the computer.

IDE Primary/Secondary Master/Slave PIO

The four IDE PIO (programmed Input/Output) filed 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.

B. Power On By Keybrd/Mouse

Set to Pwr Button to control the system power via the button on your system
case. Set to Mouse Click to turn on the power via a PS/2 mouse, and set to Hot
Key or Password to turn on the power via keyboard. With Hot Key and Password

you must decide on which keys will turn on the power.

C. COM2 Mode

When this function is Enabled, then the COM port will be redirected to support
IR function.

D. USB Keyboard Support

If your current operating system doesn't support USB drivers (i.e., DOS) this
function must be enabled for USB keyboard operation in these operating systems.

@ When using a USB keyboard this function is automatically Enabled during

bootup regardless of its setting in BIOS.

User's Manual

3-8 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
3-3). When the Security Option function is set to Setup, a password is required to
enter BIOS and change BIOS settings. When the Securitiy Option function is set
to System, a password is required to to enter both BIOS and the the computer's
operating system (for example Windows 95) found on the boot drive. This is shown
in Figures 3-9 and 3-10.

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
passorword in BIOS (See Figure 3-10 below). Note that when there is no supervisor
password set, the user password controls access to all BIOS settings (See Figure
3-9 below).
