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, adding or removing expansion cards
etc. Not doing so may result in electrical shock or severe damage to your
mainboard and peripherals!

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.

* CPU Speed = Frequency ratio x System Frequency

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 the CPU
and the extent to which the the frequency has been overset. The mainboard manufacturer
highly discourages overclocking as it may result in data loss, CPU burn-out, system
failure, etc.

Chapter 2

Voltage 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 JP10 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 PowerAT Power

This mainboard supports two kinds of power connectors
and requires a power supply of at least 200 watts. If you
want to use an AT power supply, short pins 1 and 2 with the
jumper cap. If you want to use an ATX power supply, short
pins 2 and 3 with the jumper cap.

AT Power Supply Connector (CN2)

Most power supplies have two sets of six-wire leads.
Making sure the black wires of each lead are in the center,
plug both leads into the AT power supply connector. The
power supply requirement is as follows:

10

ATX Power Supply Connector (CN5)

The ATX power supply provides a single 20-pin connector
interface which incorporates standard +/-5V, +/-12V,
optional 3.3V and soft-power signal.

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.

Hardware Setup

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 turns
on and can be remotely accessed. Please enable the Power on by Modem function in
BIOS's Power Management menu to activate this function. (See Section 3-4)

CPU/System Cooling Fan Connectors (CPUFAN/SYSFAN)

These added connectors allow the fans to draw their
power from the mainboard instead of the disk drive
connector. These fan connectors are available because
some systems have all the disk drive power connectors
in use.

Front Panel Connector Set (CN7) 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 PWRBTN
function in BIOS's Power Management Setup must set to
"Delay 4 Sec." to activate this function.
(See Section 3-4)

When the Soft-off by PWRBTN function is enabled,
pushing the power button rapidly will switch the system
between Full-On and Suspend mode. Pushing the button
rapidly again or any occurence of external activity such as
pressing a key on the keyboard will bring the system back
to Full-On. Pushing the button while in Full-On for more
than 4 seconds will switch the system to Soft-off and
pushing the button again rapidly will turn the system back

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 will not have to be replaced, relieving the user
wasted time and inconvenience.

USB Kit Connector (CN1) A through C

The USB Kit connector is a combination of of USB, PS/
2 mouse, and Infrared functions grouped on the same
connector. The USB Kit (Figure 1-5) is installed in a back
panel of the chassis and is connected to the USB Kit
connector with an 18-pin cable.

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. It's 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.

2-6 Main Memory Configuration

The DRAM memory system on board consists of 3 banks, and the memory range is
8 ~ 256 MBytes. You must install 2 SIMM modules(same size, same speed, either
single or double sided) in each bank at a time. It does not matter which bank you
install first.

Parity Both parity and non-parity modules may be used

however the parity function is not supported by this
mainboard.

Most SDRAM will be 3.3V only (i.e. SDRAM I/O pins will not be 5V
tolerant). It is not recommended to mix 3.3V EDO/SDRAM DIMM with
5V EDO/FPM SIMM.

Because 64/128MB DIMM is not yet mainstream, the compatibility of 64/
128MB DIMM can not be 100% guaranteed.

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.

16

Hardware Setup

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

This board has two DIMM (Dual-in-line Memory Module) sockets to support
SDRAM type DRAM and has the better optimized read timings (7-1-1-1).
The DIMM sockets will quickly replace SIMM as the next module standard
for the PC industry and will become the memory subsystems standardized 64­bit data interface. Recently, JEDEC committee passed the unbuffered DIMM
pinout specification as a standard for higher speed transfer. The unbuffered
DIMM allows for SDRAM, EDO and FPM DRAM compatibility as well as
pinouts for x64, x72 with parity, x72 with ECC and x80 ECC. The unbuffered
DIMM is distinguished by the keyed notch lying to the right of the centerline
of the DRAM key position as shown in the figure below.

3-1 Standard CMOS Setup

The Standard CMOS Setup allows users to configure system components such as
hard disk drive, floppy disk drive and video display as well as date, time and boot­up error signaling. This configuration menu should be changed when installing a
mainboard for the first time, changing hardware in your system such as the HDD,
FDD, video display, or when the CMOS data has been lost or contaminated. Choose
the Standard CMOS Setup option from the CMOS Setup Utility menu (Figure 3-1)
to display the following screen. When a field is highlighted, on-line help information
is displayed on the left bottom edge of the screen.

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).
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

21

Chapter 3

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

Chapter 3

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
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.

24

Award BIOS Setup Program

Typematic Delay (Msec)

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

E. Security Option

The Supervisor and/or User Password functions shown in Figure 3-1 must be set
to take advantage of this function. See Section 3-8 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.

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. 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.

26

Award BIOS Setup Program

B. System BIOS Cacheable

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

C. Memory Hole at 15MB Addr.

Enabling this feature will reserve the 15MB to 16MB memory address space 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.

D. AGP

This function must be enabled when using an AGP card. If you disable this function
you can still use an AGP card. However, the AGP card will only have PCI card
performance.

E. AGP Aperture Size

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 is alloted to the AGP card and the card only needs 8MB, the remaining
8MB will be available for system use.

F. AGP-2X Mode

Enable this setting to utilize the 2X mode (twice as fast as 1X) offered by advanced
AGP cards. Your VGA card must support 2X mode in order to take advantage
of the faster speed.

G. Flash BIOS Protection

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

H. System Monitoring and Alerting (Optional)

These optional system health monitoring features are available when an EISCA
v1.0 compliant fan is connected to the Fan 78 connector on your mainboard.
Change the CPU warning temperature according to the specifications of your CPU.

For more information about EISCA fans, see Apendix II of this manual.

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 Maximum Saving, User Define, or Minimum Saving described

28

Award BIOS Setup Program

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 Option

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

29

Chapter 3

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

DPMS Supported - Select this option if your video card supports the Display
Power Management Signaling (DPMS) standard (i.e., you have a monitor that

supports Green features). Use software supplied by your video subsystem
to set video power management options.

E. Modem Use IRQ

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

F. Soft-Off by PWRBTN

When Enabled, 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 power
button.

G. HDD Power Down

To enable this function, make sure the Power Management function is not set
to disabled. 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.

H. Doze Mode

To enable this function, make sure the Power Management function is not set
to disabled. 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.

I. Suspend Mode

To enable this function, make sure the Power Management function is not set
to disabled. If the system runs in Dozemode and the Suspend timer expires, all
devices regulated by power management will shut off and the CPU speed will
be 0 MHz.

30

Award BIOS Setup Program

J. Power On By Modem

When enabled, a modem that receives a call will wake up the system from Soft­off or Green mode. To activate this function, you must leave your modem on
and use the Software Power off. See the Software Power-Off control description
in Section 2-4 of this manual.

K. 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 pwer supply and Software Power-Off. See
the Software Power-Off control description in Section 2-4 of this manual.

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.

32

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 would 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 Cards (non-PnP ISA cards), please set the 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 on these devices.
@ 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. FDD IRQ Can Be Free

This function allows users to choose if the FDD IRQ is able to be freed for use
with other processes that require IRQ.

F. Assign IRQ For VGA

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

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).

Mainboard Software Guide

In the following installation instructions, drive D:\ is assumed to be your CD­ROM disk drive.

4-1 VIA ACPI Patch for Win95

Windows 95 software was written before the VIA chipset on your mainboard was
designed and manufactured. Thus, the newer chipset contains information not
recognized by Windows 95. This problem results in an abnormal appearance of
question and/or exclamation marks in the Windows 95 Device Manager window.
You can verify this problem by looking at the Windows 95 Device Manager
window via the following pathway: Start/Settings/Control Panel/System/Device
Manager. The chipset manufacturer has written a Patch file that allows Windows
95 to identify all the components of the chipset. Installing this Patch file will
remove question and/or exclamation marks. However, since the performance of
Windows 95 was not compromised by the lack of this patch, there will be no
increase in Windows 95 performance after installation.

To use the auto-install feature to install the VIA ACPI Patch, do the following:

1. Start Windows 95.

4-7 Award DMI Configuration Utility

DMI (Desktop Management Interface) is a new method of managing comput­ers in an enterprise network. The main component of DMI is the
MIFD(Management Information Format database). This database contains all the
information about the computing system and its components. Using DMI, a system
administrator can obtain the types, capabilities, operational status, installation data
and other information about the system components.

We support DMI features in BIOS and provide a DMI utility to maintain a
MIFD file.

The system BIOS uses the same technology implemented for plug and play to
allow dynamic real-time update system information and store those collected
information (e.g. CPU type and speed, Bus frequency , memory size and speed) block
in the motherboard's Flash EPROM.
We also provide a friendly DMI utility (DMICFG.EXE) to allow the system
integrator or end user to place necessary information in MIFD such as the serial
number on the motherboard, add-on cards, monitor, etc. This information is not
detected by the system BIOS and has to be manually input through the DMI
utility.

46

Mainboard Software

The DMICFG.EXE(DMI Configuration Utility for modifying/reviewing the MIFD)
contained in Drivers Disk that comes with your mainboard.

Please remove (or remark) any installed Memory Management Utility
