2. Insert the BOARDLOCK BODY into the MAIN
BODY. Then turn the BOARDLOCK BODY clock­wise until it can be turned no more (there is a stop­per device on the MAIN BODY). Then the
BOARDLOCK BODY is secured on the MAIN
BODY.

3. Push the BOARDLOCK PINs all the way down.
The PINs automatically turn to an angle and lock
inside the BOARDLOCK BODYs. Then pull the
PIN back up to the stopper in order for the
BOARDLOCK BODY to be easily inserted into the
PC BOARD. For the ease in installation,
BOARDLOCK BODYs should be inserted into the
UNIVERSAL RETENTION MODULE before it is
installed onto the PC BOARD. Then you only need
to push the BOARDLOCK PINs all the way down
and the MODULE would be set up tightly on the
PC BOARD.

1. Before installing the UNIVERSAL RETENTION
MODULE, pull the supporting EARs 90o outward
until you hear a Click and both EARs sit upright
in the notches of the main body.

2.4 66/100MHz System Configuration

The jumper 1 (JP1) allows you to set FSB (Front Side Bus) to be 66 or 100MHz configuration.
When you set FSB to 66MHz, you can select the system bus frequency from 66MHz to

83.3MHz through CPU Host Clock (CPU/PCI) of Chipset Features Setup in BIOS Setup
(Please refer to page 28). When you set FSB to 100MHz, you can select the system bus
frequency from 100MHz to 150MHz through CPU Host Clock (CPU/PCI) of Chipset
Features Setup in BIOS Setup (Please refer to page 28).

NOTE: If you are not familar with this feature, we recommend you set this jumper to

2.5 CPU Internal Frequency Ratio Setting

The switch 1 (SW1) is designated for adjusting the CPU internal frequency ratio.The
frequency ratio is defined as the table shown below. The internal frequency can be calculated
by the following formula:

CPU internal frequency = frequency ratio x system bus frequency *

* System bus frequency is set in CPU Host Clock (CPU/PCI) of Chipset Features Setup in
BIOS Setup (Please refer to page 28).

NOTE: Because Intel has locked the frequency ratio for new CPUs, setting SW1 to
adjust the frequency ratio is useless. Howerer, it is effective for old version CPUs.

18 BIOS SETUP

CHAPTER 3 BIOS SETUP

3.1 BIOS Setup

Award BIOS has a built-in Setup program that allows users to modify the basic system con­figuration. This information is stored in CMOS RAM. So, it can retain the Setup information
when the power is turned off. When the battery of CMOS fails, it will cause the data lost.
When it happens, you should set up your configuration parameters again after replacing the
battery.

3.2 The Main Menu

As you turn on or reboot the system, the BIOS is immediately activated. It will read the system
configuration information, and check the system through Power On Self Test (POST). During
the POST process, press the [Del] key, and you can enter the Award BIOS configuration
system. The following screen will appear.

In the Award BIOS system, you can use the arrows (
the [Enter] key to enter the sub-menu. The following keys help you navigate in Setup.
[ Esc ] Main Menu: Quit and not save changes into CMOS RAM

Other pages: Exit current page and return to Main Menu
[ PgUp ] Increase the numeric value or make changes
[ PgDn ] Decrease the numeric value or make changes
[ + ] Increase the numeric value or make changes
[ - ] Decrease the numeric value or make changes

This motherboard can support four IDE devices. We recommend that you select type
AUTO for all drives. The BIOS can automatically detect the specifications and optimal
operating mode of almost all IDE hard drives. When you select type AUTO for a hard
drive, the BIOS detects its specifications during POST while the system boots. If you do
not want to select drive type AUTO, other methods of selecting the drive type are also

available.

BIOS SETUP 21

1. Match the specifications of your installed IDE hard drive(s) with the preprogrammed

values for drive type 1 through 45.

2. Select USER and enter values into each drive parameter field.

3. Use the IDE HDD AUTO DETECTION function in Main Menu.
Here are the brief explanation of drive specifications.

* TYPE : The BIOS contains a table of pre-defined drive types. Each defined drive type

has a specified number of cylinders, number of heads, write precompensation fac­tor, landing zone, and number of sectors. Drives whose specifications do not ac­commodate any pre-defined type are classified as type USER.

* SIZE : Disk drive capacity (approximately). Note that this size is usually slightly greater

than the size of a formatted disk given by a disk-checking program.
* CYLS : Number of cylinders
* HEAD : Number of heads
* PRECOMP : Write precompensation cylinder
* LANDZ : Landing zone
* SECTOR : Number of sectors
* MODE : AUTO, NORMAL, LARGE, or LBA

- AUTO : The BIOS automatically determines the optimal mode.

- NORMAL : Maximum number of cylinders, heads, and sectors supported are

1024, 16, and 63 respectively.

- LARGE : For drives that do not support LBA and have more than 1024

cylinders.

- LBA (Logical Block Addressing) : During drive access, the IDE controller trans­forms the data address described by sector, head, and cylinder number into a
physical block address. This will significantly improve data transfer rates for
drives with greater than 1024 cylinders.

3.4 BIOS Features Setup

This BIOS FEATURES SETUP option allows you to improve your system performance and
set up system features according to your preference.

•

Virus Warning

When the function is enabled, you will receive a warning message if a program (specifi­cally, a virus) attempts to write to the boot sector or the partition table of the hard disk
drive. You should then run an anti-virus program. Keep in mind that this feature protects
the boot sector only, not the entire hard drive.

NOTE: Many disk diagnostic programs that access the boot sector table can trigger
the virus warning message. If you plan to run such a program, we recommend that
you first disable the virus warning.

• CPU Internal Cache / External Cache

Cache memory is additional memory that is much faster than conventional DRAM (sys­tem memory). CPUs from 486-type or up contain internal cache memory. Most, but not all,
modern PCs have additional (external) cache memory. When the CPU requests data, the
system transfers the requested data from the main DRAM into cache memory for even
faster access by the CPU. The External Cache field may not appear if your system does
not have external cache memory.

• Processor Number Feature

This option is for INTEL Processor-3 CPU ,End user can choose open or close it

24 BIOS SETUP

• CPU L2 Cache ECC Checking

Select Enabled to make sure the data accuracy.

• Quick Power On Self Test

Select Enabled to reduce the amount of time required to run the Power On Self Test
(POST). A quick POST skips certain steps. We recommend that you normally disable
quick POST. Its better to find a problem during POST than to lose data during your work.

• Boot Sequence

The original IBM PCs load the DOS operating system from drive A (floppy disk). So, IBM
PC-compatible systems are designed to search for an operating system first on drive A,
and then on drive C (hard disk). However, the BIOS now offers 11 different boot sequence
options. In addition to the traditional drives A and C, options include IDE hard drives D, E,
and F; plus a SCSI hard drive, a LS/ZIP drive and a CD-ROM drive.

• Swap Floppy Drive

This field is effective only in systems with two floppy drives. Selecting Enabled assigns
physical drive B to logical drive A, and physical drive A to logical drive B.

• Boot Up Floppy Seek

While enabled, the BIOS will seek drive A once.

• Boot Up NumLock Status

Toggle between On and Off to control the state of the NumLock key when the system
boots. When toggled On, the numeric keypad generates numbers instead of controlling
cursor operations.

• Gate A20 Option

Choose Fast (default) or Normal. Fast allows RAM access above 1MB to use the fast
gate A20 line.

•

Typematic Rate Setting

When this function is disabled, the following two items (Typematic Rate and Typematic
Delay) are irrelevant. Keystrokes repeat at a rate determined by the keyboard controller in
your system. When this function is enabled, you can select a typematic rate and typematic
delay.

BIOS SETUP 25

•

Typematic Rate (Chars / Sec)

When the typematic rate setting is enabled, you can select a typematic rate (the rate at
which character repeats) when you hold down a key of 6, 8, 10,12, 15, 20, 24 or 30
characters per second.

•

Typematic Delay (Msec)

When the typematic delay setting is enabled, you can select a typematic delay (the delay
before key strokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.

•

Security Option

If you have set a password, select whether the password is required while the system
boots, or only when you enter Setup.

•

PCI/VGA Palette Snoop

This function is used to prevent conflict when a MPEG card or some capture cards use the
same palette address. Enable this to make the cards work normally.

•

OS Select for DRAM > 64MB

Select OS2 only if you are running OS/2 operating system with greater than 64 MB of
RAM on your system.

•

If your hard disk supports this function, select Enabled.

•

Report No FDD For WIN95

Select Yes to report when there is no floppy disk drive under win95 operating system.

•

Video BIOS Shadow

Software that resides in a read-only memory (ROM) chip on a device is called firmware.
The Award BIOS permits shadowing of firmware such as the system BIOS, video BIOS,
and similar operating instructions that come with some expansion peripherals, such as
a SCSI adapter. Shadowing copies firmware from ROM into system RAM, where the
CPU can read it through the 64-bit DRAM bus. Firmware not shadowed must be read
by the system through the 8-bit or 16-bit X-bus. Shadowing improves the performance
of the system BIOS and similar ROM firmware for expansion peripherals, but it also
reduces the amount of high memory (640KB to 1MB) available for loading device
drivers, etc. Enable shadowing

26 BIOS SETUP

each section of memory separately. Many system designers hardwire shadowing of the
system BIOS and eliminate a System BIOS Shadow option. Video BIOS shadows into
memory area C0000-C7FFF. The remaining areas shown on the BIOS Features Setup
screen may be occupied by other expansion card firmware. 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.

3.5 Chipset Features Setup

This option will change the values of the chipset registers and the system setting will alter.
Do not change any values if you are not familiar with the chipset.

•

Auto Configuration

Auto configuration selects predetermined optimal values of chipset parameters. When
this function is disabled, chipset parameters revert to setup information stored in CMOS.
Many fields in this screen are not available when Auto Configuration is enabled.

•

EDO DRAM Speed Selection

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

•

EDO CASx# MA Wait State / EDO RASx# MA Wait State

Because the normal DRAM access speed is lower, CPU must wait for DRAM, this
function could set up DRAM Memory Access wait state.

BIOS SETUP 27

•

SDRAM RAS-to-CAS Delay

This controls the latency between SDRAM active command and the read/write command.
Leave on default setting.

•

SDRAM RAS Precharge Time

This controls the idle clocks after issuing a precharge command to SDRAM. Leave on
default setting.

•

SDRAM CAS Latency Time

This controls the SDRAM performance, default is 3 clocks. If your SDRAM DIMM specifi­cation is 2 CAS latency, change 3 to 2 for better performance.

•

SDRAM Precharge Control

This option is to determine the number of clocks required to deassert RAS and the timing
for SDRAM to do precharge before next RAS can be issued.

•

DRAM Data Integrity Mode

NON-ECC : Disable Error Correct Check function.
ECC : Enable Error Correct Check Function.

•

System BIOS Cacheable

Selecting Enabled allows caching of the system BIOS. This action can increase system
performance.

•

Video BIOS Cacheable

Selecting Enabled allows caching of the video BIOS. This action can increase system
performance.

•

8 Bit I/O Recovery Time

Recovery time is needed for old 8-bit ISA cards. Default setting is 1 ISA clock. If you find
any unstable 8-bit ISA card, you may try to extend the I/O recovery time.

•

16 Bit I/O Recovery Time

Recovery time is needed for 16-bit ISA cards. Default setting is 1 ISA clock. If you find any
unstable 16-bit ISA cards, you may try to extend the I/O recovery time.

28 BIOS SETUP

•

Memory Hold At 15M-16M

Enabling this feature reserves memory address space from 15MB to 16MB to ISA expan­sion cards that specifically require this setting. This makes the memory from 15MB and up
unavailable to the system. Expansion cards can only access memory up to 16MB. The
default is Disabled.

•

Passive Release

ISA access speed is lower than PCI access speed. While power on, the ISA interface
would release master bus control. The master bus control will go back ISA until other
device accesses data.

•

Delayed Transaction

PCI access speed is faster than ISA. So PCI would release master bus to ISA interface for
accessing data. Then the master bus control would go back to PCI again.

•

AGP Aperture Size (MB)

Select the size of the Accelerated Graphics Port (AGP) aperture.The aperture is a portion
of the PCI memory address range dedicated to graphics memory address space. Host
cycles that hit the aperture range are forwarded to the AGP without any translation. For
more information, please refer to www.agpforrum.org for AGP information.

•

CPU Host/PCI Clock (CPU/PCI)

This function allows you to set FSB frequency of the CPU and the speed of PCI bus.

3.7 PnP/PCI Configuration Setup

This section describes configuring the PCI bus system. PCI (Personal Computer Intercon­nect) is a system which allows I/O devices to operate at speeds nearing the speed that CPU
itself uses when communicating with its own special components. This section covers some
very technical items and it is strongly recommended that only experienced users can make
some changes.

BIOS SETUP 33

• PNP OS Installed

This field allows you to use a Plug-and-Play (PnP) operating system to configure the PCI
bus slots instead of using the BIOS. Thus interrupts may be reassigned by the OS when
Yes is selected. When a non-PnP OS is installed in order to prevent reassigning of
interrupt settings, select the default setting of No.

• Resource Controlled by

The Award Plug and Play BIOS can automatically configure all the boot and Plug and
Play(PnP) compatible devices. If you select Auto, all the interrupt request (IRQ) and
DMA assignment fields disappear, as the BIOS automatically assigns them.
The choice: Auto and Manual.

• Reset Configuration Data

Normally, you leave this field Disabled. Select Enabled to reset Extended System
Configuration Data (ESCD) when you exit Setup, if you have installed a new add-on and
the system reconfiguration has caused such a serious conflict that the operating
system cannot boot.

34 BIOS SETUP

• IRQ-n Assigned to

When resources are controlled manually, assign each system interrupt as one of the fol­lowing types, depending on the type of device using the interrupt.

- Legacy ISA Devices, requiring a specific interrupt (such as IRQ4 for serial port1),
compli- ant with the original PC AT bus specification.

- PCI/ISA PnP devices, whether designed for PCI or ISA bus architecture, compliant

with the Plug and Play standard.

• DMA-n Assigned to

When resources are controlled manually, assign each system DMA channel as one of the
following types, depending on the type of device using the DMA.

- Legacy ISA Devices, requiring a specific DMA channel, compliant with the original
PC AT bus specification,

- PCI/ISA PnP devices, whether designed for PCI or ISA bus architecture, compliant
with the Plug and Play standard.

• PCI 1,2,3,4 Use IRQ No.

These fields set how IRQ use is determined for each PCI slot. The default setting for each
field is Auto, which uses auto-routing to determine IRQ used. The other options are
manual settings of NA, 5, 7, 9, 10, 11, 12, 14 or 15 for each slot.

• Used MEM Base Addr

This field allows you to set the base address and block size of a legacy ISA card that uses
any memory segment within the C800H and DFFFH address range. If you have more than
