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

1. 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.

2. Note that when removing the processor, these snaps should 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.

3 . Also note that like PCI and ISA slots, Slot 1 has a divider that prevents backwards

insertion of the CPU.

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.

2-3 Setting Your CPU's Parameters(

SeePU

Technology)

SeePU is a new user friendly technology that enables the user to setup a mainboard's
CPU parameters through an easy to use BIOS setup procedure. It is no longer necessary
to make many jumper settings as on conventional mainboards.

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 SeePU & Chipset Setup menu and press Enter. Find the CPU

Setup commands at the right hand side of the BIOS screen (Figure 2-2) Commands
for operating the cursor in BIOS are found at the Bottom right of the BIOS screen.

Chapter 2

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.

Many Pentium II 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, for 66MHz external clock CPUs, the CPU boot-up speed is
233MHz. For 100MHz external clock CPUs, the CPU boot-up speed is
350MHz.)

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

Hardware Setup

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 (CN4)

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 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 ModemPower-On By Modem

Power-On By Modem

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 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.

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 cables and pin orientation (i.e., not to
reverse the order of these two connectors.)

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.

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 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.

WOL (Wake-on-LAN) Connector (CN5)

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 (Wake-on­LAN) 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 standby signal 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 poly-fuse 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.

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.

Hardware Setup

SPD (Serial Presence Detect)

This is an EPROM that contains speed and design information about the memory
module. The mainboard queries the module and makes adjustments to system
operation based on what it finds.

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 SeePU&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.

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 Mode t ype

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. VIRUS PROTECTION

Anti-Virus Protection

This is an anti-virus code incorporated in the mainboard's BIOS firmware. During
the boot-up sequence, BIOS loads before loading of the partition table or boot
sector. The anti-virus code loads with BIOS and is able to detect boot-up viruses
before they have a chance to infect the hard drive. This function employs rule­based 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

25

User's Manual

2 external cache. Both settings are left enabled to significantly increase the
performance of your computer.

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.

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.

26

Award BIOS Setup Program

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.

J. 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.

27

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.

K. Onboard NCR BIOS

Some NCR cards don't have BIOS onboard. Set this function to Enabled if the
card don't have BIOS onboard. Disabled this function if the NCR card is with
a BIOS onboard.

With the exception of the CPU Setup, 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 CAS Latency Time

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.

29

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. 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. 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.

F. 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.

G. 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.

30

Award BIOS Setup Program

H. 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.

I. 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.

J. 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.

K. CPU Setup

The mainboard manufacturer developed SeePU technology that allows you to
easily change your CPU's clock mulfiplier factor and CPU Bus frequency
in BIOS. Refer to Section 2-3 for details.

given to each device attached to the computer. With ACPI, the operating system
can turn off peripherals devices, such as CD-ROM players, when they are not
in use.

32

Award BIOS Setup Program

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.

C. 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.

33

User's Manual

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. 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.

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. 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.

34

Award BIOS Setup Program

@

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.

H. 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.

I. 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.

J. 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.

K. 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.

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. CPUFAN Off In Suspend

When enabled, this function turns off the CPU fan when the computer is in suspend
mode.

N. 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.

O. 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.

P. Wake Up On LAN

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

Q. 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.

R. Shutdown Temperature

The system will shutdown when the temperature setting is reached , to prevent
the system from overheating. (This support Windows 98 ACPI function only)

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.

37

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. 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.

F. 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.)

G. Assign IRQ For USB

If USB is employed this function must be Enabled. Otherwise, disable this
function to optimize Windows 95 IRQ resources for other IRQ usage.

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 3-10 and 3-11.

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 3-11 below). Note that when there is no supervisor
password set, the user password controls access to all BIOS settings (See Figure
3-10 below).
