BIOS SETUP
BIOS Setup
This chapter describes the different settings available in the Award
BIOS that comes with the board. The topics covered in this chapter are
as follows:
The Award BIOS (Basic Input/Output System) installed in your
computer system’s ROM supports Intel 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.
Note:
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.
Warning:
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.

With the field, there is the option to choose, aside from the hard disks connected,
“Bootable add-in Cards” which refers to other external devices.
CPU 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.
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 to Enabled, BIOS will skip some
items.

transfer data to and from your hard disk drive.
IDE DMA Transfer Access
This field, by default, is enabled
OnChip Secondary PCI IDE
This field, by default, is enabled
IDE Primary/Secondary Master/Slave PIO
These fields allow your system hard disk controller to work faster.
Rather than have the BIOS issue a series of commands that transfer to or
from the disk drive, PIO (Programmed Input /Output) allows the BIOS to
communicate with the controller and CPU directly.
The system supports five modes, numbered from 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select
the best available mode.
IDE Primary/Secondary Master/Slave UDMA
These fields allow your system to improve disk I/O throughput to
33Mb/sec with the Ultra DMA/33 feature. The options are Auto and
Disabled.
SATA Mode
The setting choices for the SATA Mode are IDE, RAID and AHCI
Mode. Select [IDE] if you want to have SATA function as IDE.
Select [AHCI] for Advanced Host Controller Interface (AHCI) feature,
with improved SATA performance with native command queuing &
native hot plug. Select [RAID] to use SATA as RAID function. RAID
function is supported on the board if it uses ICH9R, but this is optional.
LEGACY Mode Support
When the Serial ATA (SATA) is set with the legacy mode enabled, then
the SATA is set to the conventional IDE mode. Legacy mode is
otherwise known as compatible mode.
Power ON Function
This field is related to how the system is powered on – such as with th e
use of conventional power button, keyboard or hot keys. The default is
BUTTON ONLY.

the mode of the Power ON function.
Hot Key Power ON
This field sets certain keys, also known as hot keys, on the keyboard that
can be used as a ‘switch’ to power on the system.
Onboard Serial Port
These fields allow you to select the onboard serial and parallel ports and
their addresses. The default values for these ports are:
Serial Port 1 3F8/IRQ4
Serial Port 2 2F8/IRQ3
UART Mode Select
This field determines the UART 2 mode in your computer. The default
value is Normal.
PWRON After PWR-Fail
This field sets the system power status whether on or off when power
returns to the system from a power failure situation.
USB 1.0 Controller
The options for this field are Enabled and Disabled. By default, this field
is set to Enabled.
USB 2.0 Controller
The options for this field are Enabled and Disabled. By default, this field
is set to Enabled. In order to use USB 2.0, necessary OS drivers must be
installed first. Please update your system to Windows 2000 SP4 or Windows XP SP2.

drive will be powered down while all other devices remain active.
Soft-Off by PWRBTN
This field defines the power-off mode when using an ATX power
supply. The Instant Off mode allows powering off immediately upon
pressing the power button. In the Delay 4 Sec mode, the system powers
off when the power button is pressed for more than four seconds or
enters the suspend mode when pressed for less than 4 seconds.
CPU THRM-Throttling
When the system enters Doze mode, t he CPU clock runs only part of the
time. You may select the percent of time that the clock runs.

This field enables or disables the resumption of the system operation.
When enabled, the user is allowed to set the Date and Time.
Reload Global Timer Events
The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events that can
prevent the system from entering a power saving mode or can awaken
the system from such a mode. When an I/O device wants to gain the
attention of the operating system, it signals this by causing an IRQ to
occur. When the operating system is ready to respond to the request, it
interrupts itself and performs the service.

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 sorts 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.
