Hardware SetupHardware Setup

If your mainboard has already been installed in your computer you may still need
to refer to this chapter if you plan to upgrade your system's hardware.

Be sure to disconnect the power cable from the power source before performing
any work on your mainboard, i. e. installing a CPU, memory module, changing
a jumper setting, etc. Not doing so may result in electrical shock!

2-1 Introduction to Jumpers

Jumpers are used to select between various operating modes. A jumper consists of
a row of gold colored pins that protrude from the surface of the mainboard. It is
important not to confuse jumpers with connectors or headers.

Putting jumper caps on anything that is not a jumper may result in damaging
your mainboard. Please refer to Section 1-3, Mainboard Layout, for the location
of jumpers on your mainboard.

As indicated in Figure 2-1 below, a cap is used to cover the pins of a jumper, resulting
in shorting those pins that it covers. If the cap is removed from the top of the pins,
the jumper is left "open." The number 1 shown both in the diagram below and in
all multiple pin jumper and header diagrams in this manual indicates the pin designated
with the number 1. The numbering of the remaining pins follows in sequence.

2-2 Installing a PGA type CPU in a ZIF Socket

The Intel Socket 7, designed for the Pentium processor, has been incorporated as
a standard mainboard specification and is compatible with AMD and Cyrix CPUs. To
insert your CPU into Socket 7 please do the following:

1. Locate a small dot marked on the top surface of the CPU close to one if it's
corners. The same corner will also be cut off, leaving a noticeable notch in the
CPU's corner. These markings indicate Pin 1 of the CPU. See Figure 2-2.

Figure 2-2 The markings on top of a CPU

2. Pull up the lever of Socket 7 so that it is perpendicular with the surface of the
mainboard. Gently insert the CPU with Pin 1 at the same corner of Socket 7 that
contains the end of the lever. Allow the the weight of the CPU to push itself into
place. Do not apply extra pressure as doing so may result in damaging your CPU.
Snap the lever back into place. See Figure 2-3.

Figure 2-3 Inserting a CPU into Socket 7

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.

Chapter 2

Overclocking

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

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

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

2. Turn on your computer, wait for five seconds and then release the Home key.
(Pressing the Home key allows the computer to boot at a low system speed.
For example, 66MHz external clock CPUs boot-up at 133MHz.)

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

Voltage ConfigurationVoltage Configuration

Voltage Configuration

Voltage ConfigurationVoltage Configuration

There are two major processor types in general use-

-single and dual voltage processors. Most single
voltage processors such as Pentium, AMD-K5, Cyrix
6x86 and IDT C6 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 JP7 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.

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 Soft­Off mode, this trickle supply maintains the system in it's
minimum power state.

Software Power-Off Control

This mainboard can be powered down using theWindows 95 Software Power-Off
function. To power down your computer, click the START button on the Windows 95
Task Bar. Select "Shut Down The Computer" and the system turns off. The message
"It is now safe to turn off your computer" will not be shown when using this function.

way to connect up to 125 devices to a single computer
port. Keyboards, mice, tablets, digitizers, scanners, bar-

1

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.

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 short 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 of wasted time and
inconvenience.

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

PRECOM P 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

Trend ChipAway Virus

Trend ChipAway Virus is a code incorporated in the mainboard's BIOS firmware.
During the boot-up sequence, BIOS loads before loading of the partition table
or boot sector. ChipAway Virus loads with BIOS and is able to detect boot-up
viruses before they have a chance to infect the hard drive. ChipAway Virus employs
rule-based logic that doesn't look for specific viruses but rather detects patterns
found in every virus, eliminating the need to perform periodical version updates
after new viruses have been found.

Boot Sector Intrusion Alert

When Enabled, BIOS activates a warning message to the user when any program
(i.e., a virus) attempts to write to 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.

23

User's Manual

B. CACHE CONTROL

CPU Internal Cache/External Cache

Cache memory is much faster than conventional DRAM system memory. These
fields allow you to enable or disable the CPUs Level 1 built-in cache and Level
2 external cache. Both settings are left enabled to significantly increase the
performance of your computer.

C. BOOT UP FEATURES

After turning on the system, BIOS will perform a series of device 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. Shadow Memory

Software such as system BIOS, video BIOS, SCSI BIOS, etc that resides in ROM
(Read Only Memory) chips is called firmware. Shadowing of firmware occurs when
BIOS is copied to RAM address C0000h through DFFFFh. Video BIOS loads into
the C0000-C7FFF memory area when video shadowing is enabled. If an expansion
peripheral in your system contains ROM-based firmware, you need to know the
address range the ROM occupies to shadow it into the correct area of RAM.

Shadowing improves the firmware's performance because the firmware can be read
by the CPU through the 16- or 32-bit DRAM bus as opposed to the 8-bit XT bus.
However, shadowing also results in reducing the amount of high memory (640
KB to 1 MB) for loading device drivers. Shadowing is used mostly for ROM chips
on ISA cards and not for PCI cards. Shadowing and playing games at the same
time may result in system instability as some games access the RAM memory area
being shadowed.

Figure 3-4 Chipset Features Setup Screen

All of the above settings have been determined by the mainboard manufacturer
and should not be changed unless you are absolutely sure of what you are
doing. Explanation of the DRAM timing and chipset features setup is lengthy,
highly technical and beyond the scope of this manual. Below are abbreviated
descriptions of the functions in this setup menu. You can look on the world
wide web for helpful chipset and RAM configuration information including
AWARD's web site at http://www.award.com.

A. 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.

26

Award BIOS Setup Program

B. L2 TAG RAM Size

The system uses tag bits to determine the status of data in the L2 cache. Set this
field to match the specifications (8 or 10 bits) of the installed tag RAM chip.

C. AT Bus Clock

This function allows you to set the speed of the AT bus in terms of a fraction
of the CPU clock speed,(PCKL2) or at the fixed speed of 7.16KHz.

D. DRAM Timing

The value in this field depends on performance parameters of the installed memory
chips. (DRAM) Do not change the value from the factory setting unless you install
a new memory that has a different performance rating than the original DRAM.

E. SDRAM CAS Latency

When syschronous DRAM is installed, the number of the clock cycles of CAS
latency depends on the DRAM timing.

F. Pipeline Function

When Enabled, the controller signals the CPU for a new memory address before
all data transfers fot hte current cycles are complete, resulting in faster performance.

G. Graphics Aperture Size

This function determines the amount of system memory that is given to the
Graphics card. Options range from 16MB to 256MB. This is a dynamic memory
allotment in that the Graphics 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.

H. DRAM Data Integrity Mode

This function enable you to select Parity or ECC, (Error Correcting Code) according
to the type the installed DRAM.

I. 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.

27

User's Manual

J. ISA Line Buffer

The PCI to ISA Bridge has 8-byte bi-directional line buffer for ISA or DMA bus
master memory reads from or writes to the PCI bus. When Enabled, an ISA or
DMA bus master can prefetch two double words to theline buffer for a read cycle.

K. Passive Release

When Enabled, CPU to PCI bus access is allowed during passive release.
Otherwise, the arbiter only accepts another PCI master access to local DRAM.

L. Delay Transaction

The chipset has an embedded 32-bit posted write buffer to support delay
transactions cycles. Select Enabled to support PCI specification compliance
version 2.1.

M. Primary Frame Buffer

This function allows you to select a size for the frame buffer. The size of the buffer
should not impinge on local memory.

N. VGA Frame Buffer

When Enabled, a fixed VGA frame buffer from A000h to BFFFh and a CPU to PCI
write buffer are implemented

O. Data Merge

This function controls the word-merge feature for frame buffer cycles. When
Enabled, the controller checks the eight CPU Byte Enable signal to determine
if the words read from the PCI bus by the CPU can be merge.

P. Spectrum Spread

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

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.

D. Modem Use IRQ

This function determines the IRQ in which the modem can use.

E. 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.

30

Award BIOS Setup Program

F. 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.

G. 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.

H. Doze Mode

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

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

@

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

31

User's Manual

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. Power Button

This item allows you to select the function of the power button.

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.

33

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 A T (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. Current VGA
card models do not require this function to be enabled.

G. 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.

H. Used MEM base addr

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

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).
