Watchdog Timer Configuration
The WDT is used to generate a variety of output signals after a user
programmable count. The WDT is suitable for use in the prevention of
system lock-up, such as when software becomes trapped in a deadlock.
Under these sort of circumstances, the timer will count to zero and the
selected outputs will be driven. Under normal circumstance, the user will
restart the WDT at regular intervals before the timer counts to zero.

BIOS SETUP
BIOS Introduction
The Award BIOS (Basic Input/Output System) installed in your computer
system’ s ROM supports Intel®Pentium® 4 processors. The BIOS provides
critical low-level support for a standard device such as disk drives, serial
ports and parallel ports. It also adds virus and password protection as well
as special support for detailed fine-tuning of the chipset controlling the
entire system.
BIOS Setup
The Award BIOS provides a Setup utility program for specifying the
system configurations and settings. The BIOS ROM of the system stores
the Setup utility. When you turn on the computer, the Award BIOS is
immediately activated. Pressing the <Del> key immediately allows you to
enter the Setup utility. If you are a little bit late pressing the <Del> key,
POST (Power On Self Test) will continue with its test routines, thus
preventing you from invoking the Setup. If you still wish to enter Setup,
restart the system by pressing the ”Reset” button or simultaneously
pressing the <Ctrl>, <Alt> and <Delete> keys. You can also restart by
turning the system Off and back On again. The following message will
appear on the screen:
Press <DEL> to Enter Setup
In general, you press the arrow keys to highlight items, <Enter> to select,
the <PgUp> and <PgDn> keys to change entries, <F1> for help and
<Esc> to quit.
When you enter the Setup utility, the Main Menu screen will appear on the
screen. The Main Menu allows you to select from various setup functions
and exit choices.

The section below the setup items of the Main Menu displays the control
keys for this menu. At the bottom of the Main Menu just below the
control keys section, there is another section, which displays information
on the currently highlighted item in the list.
If the system cannot boot after making and saving system
changes with Setup, the Award BIOS supports an override to
the CMOS settings that resets your system to its default.
Note:
It is strongly recommended that you avoid making any
changes to the chipset defaults. These defaults have been
carefully chosen by both Award and your system
manufacturer to provide the absolute maximum
performance and reliability. Changing the defaults could
cause the system to become unstable and crash in some
cases.

BIOS SETUP
Standard CMOS Setup
“Standard CMOS Setup” choice allows you to record some basic
hardware configurations in your computer system and set the system
clock and error handling. If the motherboard is already installed in a
working system, you will not need to select this option. You will need to
run the Standard CMOS option, however, if you change your system
hardware configurations, the onboard battery fails, or the configuration
stored in the CMOS memory was lost or damaged.

the selections shows the current hard disks used in your system as well as the
“Bootable Add-in Card” that is relevant to other boot sources media such as
SCSI cards and LAN cards.
CPU L1 and L2 Cache
Cache memory is additional memory that is much faster than conventional DRAM
(system memory). CPUs from 486-type on up contain internal cache memory,
and 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. These items
allow you to enable (speed up memory access) or disable the cache function. By
default, these items are Enabled.
Hyper-Threading Technology
This feature is enabled when your processor supports Hyper-Threading
Technology. Otherwise, this field will be hidden.
Quick Power On Self Test
When enabled, this field speeds up the Power On Self Test (POST) after
the system is turned on. If it is set toEnabled, BIOS will skip some items.

BIOS SETUP
First/Second/Third Boot Device
These fields determine the drive that the system searches first for an
operating system. The options available include Floppy, LS120, Hard
Disk, CDROM, ZIP100, USB-FDD, USB-CDROM and Disable.
Boot Other Device
These fields allow the system to search for an operating system from
other devices other than the ones selected in the First/Second/Third Boot
Device.
Swap Floppy Drive
This item allows you to determine whether or not to enable Swap Floppy
Drive. When enabled, the BIOS swaps floppy drive assignments so that
Drive A becomes Drive B, and Drive B becomes Drive A. By default, this
field is set to Disabled.
Boot Up Floppy Seek
This feature controls whether the BIOS checks for a floppy drive while
booting up. If it cannot detect one (either due to improper configuration
or its absence), it will flash an error message.
Boot Up NumLock Status
This allows you to activate the NumLock function after you power up the
system.
Gate A20 Option
This field allows you to select how Gate A20 is worked. Gate A20 is a
device used to address memory above 1 MB.
Typematic Rate Setting
When disabled, continually holding down a key on your keyboard will
generate only one instance. When enabled, you can set the two typematic
controls listed next. By default, this field is set to Disabled.
Typematic Rate (Chars/Sec)
When the typematic rate is enabled, the system registers repeated
keystrokes speeds. Settings are from 6 to 30 characters per second.
Typematic Delay (Msec)
When the typematic rate is enabled, this item allows you to set the time
interval for displaying the first and second characters. By default, this
item is set to 250msec.

BIOS SETUP
Security Option
This field allows you to limit access to the System and Setup. The default
value is Setup. When you select System, the system prompts for the User
Password every time you boot up. When you select Setup, the system
always boots up and prompts for the Supervisor Password only when the
Setup utility is called up.
APIC Mode
APIC stands for Advanced Programmable Interrupt Controller. The
default setting is Enabled.
MPS Version Control for OS
This option is specifies the MPS (Multiprocessor Specification) version
for your operating system. MPS version 1.4 added extended
configuration tables to improve support for multiple PCI bus
configurations and improve future expandability. The default setting is
1.4.
OS Select for DRAM > 64MB
This option allows the system to access greater than 64MB of DRAM
memory when used with OS/2 that depends on certain BIOS calls to
access memory. The default setting is Non-OS/2.
Report No FDD For WIN 95
If you are using Windows 95/98 without a floppy disk drive, select
Enabled to release IRQ6. This is required to pass Windows 95/98's SCT
test. You should also disable the Onboard FDC Controller in the
Integrated Peripherals screen when there's no floppy drive in the system. If
you set this feature to Disabled, the BIOS will not report the missing
floppy drive to Win95/98.
Small Logo (EPA) Show

You can configure CAS latency time in HCLKs as 2 or 2.5 or 3. The
system board designer should set the values in this field, depending on the
DRAM installed. Do not change the values in this field unless you change
specifications of the installed DRAM or the installed CPU.
Active to Precharge Delay
The default setting for the Active to Precharge Delay is 7.
DRAM RAS# to CAS# Delay
This option allows you to insert a delay between the RAS (Row Address
Strobe) and CAS (Column Address Strobe) signals. This delay occurs
when the SDRAM is written to, read from or refreshed. Reducing the
delay improves the performance of the SDRAM.
DRAM RAS# Precharge
This option sets the number of cycles required for the RAS to accumulate
its charge before the SDRAM refreshes. The default setting for the Active
to Precharge Delay is 3.

Memory Frequency For
This field sets the frequency of the DRAM memory installed. The default
setting is Auto. The other settings are DDR266, DDR333, DDR320 and
DDR400.
System BIOS Cacheable
The setting of Enabled allows caching of the system BIOS ROM at
F000h-FFFFFh, resulting in better system performance. However, if any
program writes to this memory area, a system error may result.
Video BIOS Cacheable
The Setting Enabled allows caching of the video BIOS ROM at
C0000h-F7FFFh, resulting in better video performance. However, if any
program writes to this memory area, a system error may result.
Memory Hole At 15M-16M
In order to improve performance, certain space in memory can be reserved
for ISA cards. This memory must be mapped into the memory space
below 16 MB. The choices are Enabled and Disabled.
Delay Prior to Thermal
This field activates the CPU thermal function after the systems boots for
the set number of minutes. The options are 16Min and 64Min.
AGP Aperture Size
The field sets aperture size of the graphics. The aperture is a portion of the
PCI memory address range dedicated for graphics memory address space.
Host cycles that hit the aperture range are forwarded to the AGP without
any translation. The default setting is 128M.
Init Display First
This field allows the system to initialize first the VGA on chip or the
display card on the PCI Slot.
DRAM Data Integrity Mode
This BIOS feature controls the ECC feature of the memory controller.
ECC, which stands for Error Checking and Correction, enables the
memory controller to detect and correct single-bit soft memory errors.
The memory controller will also be able to detect double-bit errors
although it will not be able to correct them. This provides increased data
integrity and system stability. However, this feature can only be enabled if
you are using special ECC memory modules.

configuration. These default settings are optimal and enable all high
performance features.
Set Supervisor/User Password
These two options set the system password. Supervisor Password sets a
password that will be used to protect the system and Setup utility. User
Password sets a password that will be used exclusively on the system. To
specify a password, highlight the type you want and press <Enter>. The
Enter Password: message prompts on the screen. Type the password, up
to eight characters in length, and press <Enter>. The system confirms
your password by asking you to type it again. After setting a password, the
screen automatically returns to the main screen.
To disable a password, just press the <Enter> key when you are prompted
to enter the password. A message will confirm the password to be
disabled. Once the password is disabled, the system will boot and you can
enter Setup freely.

This option allows you to determine whether or not to accept the
modifications. If you type “Y”, you will quit the setup utility and save all
changes into the CMOS memory. If you type “N”, you will return to Setup
utility.
Exit Without Saving
Select this option to exit the Setup utility without saving the changes you
have made in this session. Typing “Y” will quit the Setup utility without
saving the modifications. Typing “N” will return you to Setup utility.
