- System BIOS Setup
After
you have configured the system board and
assembled all the components, you need to
enter the system configuration
information to the system BIOS through
the Award PnP BIOS Setup programs. This
Award PnP BIOS Setup program and the
system configuration information are
embedded in the system board and it is
backup by the Dallas Real Time Clock.
Due to frequent update of system BIOS,
the actual options available in your
system board BIOS setups may vary
comparing with this manual. If
technically necessary, we would provide a
special insert for instruction of the
difference in regard to any changes of
the BIOS setup option.
-
- Entering BIOS Setup
Program
- Turn on or
reboot the system. After the system
finished testing the on-board memory, the
message "Hit DEL if you want to run
SETUP" will appear. Press "DEL"
key at this time will bring you into the
BIOS Setup program.
-
- Use "Arrow"
keys to high-light items, and use the
"Enter" key to select option or
you may use the mouse to "Click"
on item you want to select and change.
-
- After the
BIOS Setup program is entered, you may
want to choose the "Standard CMOS
Setup" option for date, time, and
all disk drives information. If you have
IDE Hard Drive(s) installed, the "IDE
HDD Auto Detection" option can be
used to automatically enter your hard
drive(s) information.
-
- At any time
you may press "ESC" key to exit
the window, and choose the "Exit
Without Saving" option to keep the
original configuration.
-
- Load Setup Defaults
- There is a
set of BIOS values stored in the ROM
files: The "Setup" default
values The "Setup" default
values are those settings which should
provide optimum performance for the
system. They are the best case default
values. This set of default values can be
loaded by using the "Load Setup
Defaults" option in the main BIOS
menu when you first entered the setup
utility.
-
- Standard CMOS Setup
Option
- Primary
Master & Slave, Secondary Master
& Slave Drive Types According to
your actual equipment, you can select the
type of hard disks for C, D, E, & F
from 'Not Installed' to type 46 for
standard hard disks. As for type 47, user
may define by himself. If a ATAPI IDE CD-ROM
is connected to any on-board IDE port,
the HARD DISKS "Type" should be
set to "None". The DOS CD-ROM
driver or the Win95 built-in driver will
handle the communication by themselves.
You may also use the "IDE HDD Auto
Detection" option in the Main Menu
to allow the system to detect and enter
these information for you.
-
- It is
strongly recommended that the HARD DISK
"Type" and "Mode" be
set to "Auto" to allow the BIOS
to detect and configure the hard disk(s)
since hard disks are becoming
increasingly complicated. If the
"Auto" modes are enabled, the
BIOS will perform a very reliable
operation which it will read the detail
information about the hard disk that is
embedded in the drive by the manufacturer.
This information is the true and optimal
setting for the drive and it will allow
the BIOS to properly configure the system.
-
- As it is
proven, manually setting the hard disk
parameters often causes unnecessary
troubles; from being unable to format the
disk to its full capacity to the system
simply refusing to boot. Therefore, it is
only wise to leave these settings to
"Auto" and let the system do
the job it does best.
-
- Primary
Master & Slave are the 2 IDE drives
connected to the Primary IDE port as
shown in the drawing under the "Board
Description" at the beginning of
Chapter 2. The Secondary Master &
Slave are the 2 IDE drives connected to
the Secondary IDE port. If there are IDE
device(s) installed on any of these 2
port, you must make sure the
corresponding "On-Chip Primary PCI
IDE" and/or "On-Chip Secondary
PCI IDE" in "Integrated
Peripherals Setup" is enabled.
-
- Floppy
Drives A & B
- According to
your actual equipment, set floppy drive A
& B whose five options are as
highlighted.
-
- BIOS Features Setup
- Virus
Warning
- This function,
If enabled, will detect boot sector
viruses and warning will be given when a
program attempted to change boot sector
information.
-
- CPU
Internal & External Cache
- These options
allows user to enable or disable the on-board
(External) and the on-chip(CPU Internal)
cache memories (SRAM) when special
peripheral or software implemented
indicate such requirement. System over
all speed will slow down considerably if
any of these options are disabled.
-
- 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. Better to find a problem during
POST than lose data during your work.
Boot Sequence
- The original
IBM PCs loaded 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,
modern computers usually load the
operating system from the hard drive, and
may even load it from 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
- When Enabled,
the BIOS tests (seeks) floppy drives to
determine whether they have 40 or 80
tracks. Only 360-KB floppy drives have 40
tracks; drives with 720 KB, 1.2 MB, and 1.44
MB capacity all have 80 tracks. Because
very few modern PCs have 40-track floppy
drives, we recommend that you set this
field to Disabled to save time.
Boot Up NumLock Status
Toggle between On or 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.
Boot Up System Speed
Select High to boot at the default
CPU speed; select Low to boot at the
speed of the AT bus. Some add-in
peripherals or old software (such as old
games) may require a slow CPU speed. The
default setting is High.
Gate A20 Option
Gate A20 refers to the way the system
addresses memory above 1 MB (extended
memory). When set to Fast, the system
chipset controls Gate A20. When set to
Normal, a pin in the keyboard controller
controls Gate A20. Setting Gate A20 to
Fast improves system speed, particularly
with OS/2 and Windows.
Typematic Rate Setting
When 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 Enabled,
you can select a typematic rate and
typematic delay.
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 rate setting is
enabled, you can select a typematic delay
(the delay before key strokes begin to
repeat) of 250, 500, 750 or 7900
milliseconds.
Security Option
- This option
allow a password be set up so that a
password will be needed to enter the CMOS
Setup or to boot the system including
entering CMOS Setup. After this option is
enabled, you must use the "Password
Setting" option in the main menu to
setup your password. If in any case the
password is lost or forgotten, the jumper
JP7 - Clear CMOS can be used to clear the
configuration.
-
- WARNING -
"JP7" will clear and reset ALL
and EVERY configuration parameters. Make
sure you know what you are doing or ask
someone who does to help you.
Shadow
Shadowing copies firmware from ROM
into system RAM, where the CPU can read
it through the 16-bit or 32-bit DRAM bus.
Firmware not shadowed must be read by the
system through the 8-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 (640 KB
to 1 MB) available for loading device
drivers, etc
Chipset Features Setup
- Most of
the options in this group have major
influence to the system. If options are
not set properly, it may not only greatly
affect the performance, but also it may
bring the system down unexpectedly in
most cases. Therefore, it is only wise to
leave the defaults alone unless there are
specific reason to do any change.
Auto
Configuration
- Auto
Configuration selects predetermined
optimal values of chipset parameters.
When Disabled, chipset parameters
revert to setup information stored in
CMOS. Many fields in this screen are not
available when Auto Configuration is Enabled.
-
- DRAM RAS#
Precharge Time
- DRAM must
continually refreshed or it will lose its
data. This option allows you to determine
the number of CPU clocks allocated for
the Row Address Strobe to accumulate its
electrical charge before the DRAM is
refreshed. If insufficient time is
allowed, refresh may be incomplete and
the DRAM may fail to retain data.
-
- DRAM R/W
Leadoff Timing
Select the combination of CPU clocks
the DRAM on your board requires before
each read from or write to the memory.
Changing the value from the setting
determined by the board designer for the
installed DRAM may cause memory errors.
Fast RAS# to CAS# Delay
When DRAM is refreshed, both rows and
columns are addressed separately. This
setup item allows you to determine the
timing of the transition from RAS to
Column Address Strobe (CAS).
DRAM Read (EDO/FP) / Write Burst
Timing
These 2 options set the timing for Burst
Mode reads and writes from and to the
Fast Page Mode or EDO DRAM. The burst
read and write requests are generated by
the CPU in four separate parts. The four
numbers indicate the actual data cycles.
The lower the timing number, the faster
the system will address the memory.
Fast MA to RAS# Delay CLK
The values in this field are set by
the system board designer, 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.
ISA Bus Clock
- Set the speed
of the ISA bus here. The settings are
tied to the speed of the PCI bus. If the
PCI bus operates at 33 MHz, a setting of
PCICLK/4 (default) would yield an ISA bus
speed of approximately 8 MHz, the
standard speed of the ISA bus. While most
devices operate at higher ISA bus speeds,
try a slower bus speed if your ISA device
does not function properly at a high bus
speed.
- System
BIOS Cacheable
Selecting Enabled allows
caching of the system BIOS ROM at F0000h-FFFFFh,
resulting in better system performance.
However, if any program writes to this
memory area, a system error may result. Video BIOS
Cacheable
Selecting Enabled allows
caching of the video BIOS ROM at C0000h
to C7FFFh, resulting in better video
performance. However, if any program
writes to this memory area, a system
error may result.
8/16
Bit I/O Recovery Time
The I/O recovery mechanism adds bus
clock cycles between PCI-originated I/O
cycles to the ISA bus. This delay takes
place because the PCI bus is so much
faster than the ISA bus. These two fields
let you add recovery time (in bus clock
cycles) for 16-bit and 8-bit I/O.
Peer
Concurrency
Peer concurrency means that more than
one PCI device can be active at a time.
Chipset NA# Asserted
Selecting Enabled permits pipelining,
in which the chipset signals the CPU for
a new memory address before all data
transfers for the current cycle are
complete, resulting in faster performance.
Power Management Setup
This system board is designed to fully
support the SMM/SMI power management
protocol. This option allows you to
select the type (or degree) of power
saving for Doze, Standby, and Suspend
modes.
Max
Saving
Maximum power savings. Only
Available for SL CPUs. Inactivity
period is 1 minute in each mode.
User Define
Set each mode individually.
Min Saving
Minimum power savings. Inactivity
period is 1 hour in each mode (except the
hard drive).
PM
Control by APM
If Advanced Power Management (APM) is
installed on your system, selecting Yes
gives better power savings.
Video
Off Method
Determines the manner in which the
monitor is blanked.
V/H
SYNC+Blank
System turns off vertical and horizontal
synchronization ports and writes blanks
to the video buffer.
DPMS Support
Select this option if your monitor
supports the Display Power Management
Signaling (DPMS) standard of the Video
Electronics Standards Association (VESA).
Use the software supplied for your video
subsystem to select video power
management values.
Blank Screen
System only writes blanks to the
video buffer.
MODEM Use IRQ
Name the interrupt request (IRQ) line
assigned to the modem (if any) on your
system. Activity of the selected IRQ
always awakens the system.
PM
Timers
The following modes are Green PC
power saving functions. They are user-configurable
only during User Defined Power Management
mode.
Doze
Mode
After the selected period of system
inactivity (1 minute to 1 hour), the CPU
clock runs at slower speed while all
other devices still operate at full speed.
Standby
Mode
After the selected period of system
inactivity (1 minute to 1 hour), the
fixed disk drive and the video shut off
while all other devices still operate at
full speed.
Suspend
Mode
After the selected period of system
inactivity (1 minute to 1 hour), all
devices except the CPU shut off.
HDD
Power Down
After the selected period of drive
inactivity (1 to 15 minutes), the hard
disk drive powers down while all other
devices remain active.
- Wake Up
Events
You can turn On or Off monitoring
of four commonly used interrupt requests
so they do not awaken the system from, or
reset activity timers for, Doze and
Standby modes.
- Power Down
and Resume Events
You
can disable monitoring of common
interrupt requests so they do not awaken
the system from, or reset activity timers
for, Suspend mode.

- This option,
if enabled, instruct the hard disk to
read multiple blocks of data from the
disk for one read request. You must refer
to your hard disk information to be
certain your drive support this feature.
-
- IDE
Primary & Secondary, Master &
Slave PIO Modes
- Rather than
have the BIOS issue a series of commands
to effect a transfer to or from the hard
drive, PIO(Programmed Input/Output)
allows the BIOS to tell the hard drive
controller what it wants and lets the
controller and the CPU to perform the
complete task themselves. This method is
simpler, more efficient, and so is faster.
The BIOS supports five modes(0 through 4)
and can be set to "Auto" for
each individual hard drive.
-
- Warning :
The default for the PIO Modes are "Auto",
if you manually set this parameter to a
mode that your hard drive does not
support, it will cause the HDD to crash,
lost data, and/or trash your hard drive
completely. If you are not 100% certain,
or your hard drives does not meet the ATA
specification, set the PIO Mode to "0"
for that hard disk.
-

"Parallel Mode" option, use the
"ECP Mode Use DMA" to select
DMA channel for the ECP Mode.
-
- Exiting Setup Utility
- At this point,
you can either choose to confirm your
setup entries and exit by using "ESC"
key and taking the "Save & Exit
Setup" or the "Exit Without
Saving" option to restore the
original setup parameters and exit.
-
- After you
highlight the desired option and press
<<ENTER>>, the system will
reset itself. The new or original setup
parameters, depend on the option which
you have chosen, will become the current
setting.
