Memory
The mainboard provides two 184-pin DDR DIMM slots and supports a
total memory size up to 2 GB.
DDR1 DDR2
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM modules rather than 168-pin DIMM modules used by SDR SDRAM. Two types of
DDR are available at the time of writing: PC1600 & PC2100. PC1600 DDR SDRAM
running at 100MHz will produce about 1.6GB/s memory bandwidth. PC2100
running at 133MHz will produce 2.1GB/s memory bandwidth. High memory
bandwidth makes DDR an ideal solution for high performance PC, workstations and servers.

the computer will enter the suspend/sleep mode if you press the power button.
But if the button is pressed for more than four seconds, the computer is turned
off. Setting options: Power Off, Suspend.
Wake Up On PME, Wake Up On Ring, Wake Up On LAN, USB Wakeup From
S3
These fields specify whether the system will be awakened from power saving
modes when activity or input signal of the specified hardware peripheral or
component is detected.
Note: To use the function of “Wake Up On Ring” and “Wake Up On
LAN”, you need to install a modem/LAN card supporting power on
function.
CPU THRM-Throttling
The item allows you to specify the CPU speed (at percentage) to which it will
slow down when the CPU reaches the predetermined overheat temperature.
Settings range from 12.5% to 87.5% at 12.5% increment.

Power Again
This setting specifies whether your system will reboot after a power failure or
interrupts occurs. Available settings are:
Power Off
Leaves the computer in the power off state.
Power On
Reboots the computer.
Last State
Restores the system to the status before power failure or
interrupt occurs.
Reload Global Timer Events: Primary/Secondary Master/Slave IDE, FDC/
LPT/COM Ports
Global Timer Events are I/O events whose occurrence can prevent the system
from entering a power saving mode or can awaken the system from such a
mode. In effect, the system remains alert for anything which occurs to a device
that is configured as Enabled, even when the system is in a power down mode.

PNP/PCI Configurations
This section describes configuring the PCI bus system. PCI, or Personal Computer Interconnect, is a system which allows I/O devices to operate at speeds
nearing the speed the 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 should make any changes
to the default settings.
PNP OS Installed
When set to Yes, BIOS will only initialize the PnP cards used for booting (VGA,
IDE, SCSI). The rest of the cards will be initialized by the PnP operating system
like Windows® 95 or 98. When set to No, BIOS will initialize all the PnP cards.
So, select Yes if the operating system is Plug & Play aware.
Clear ESCD
This item allows you to clear ESCD. Available options are [Disabled] and
[Enabled]. Default value is [Disabled].
Resource Controlled By
The Award Plug and Play BIOS has the capacity to automatically configure all
of the boot and Plug and Play compatible devices. However, this capability
means absolutely nothing unless you are using a Plug and Play operating
system such as Windows® 95/98. If you set this field to “manual” choose
specific resources by going into each of the sub menu that follows this field (a
3-21
Chapter 3
sub menu is preceded by a “¾”). The settings are: Auto (ESCD), Manual.
IRQ/DMA Resources
The items are adjustable only when Resources Controlled By is set to Manual.
Press <Enter> and you will enter the sub-menu of the items. IRQ Resources &
DMA Resources list IRQ 3/4/5/7/9/10/11/12/14/15 and DMA 0/1/3/5/6/7 for users to set each IRQ/DMA a type depending on the type of device using the
IRQ/DMA. Settings are:
PCI/ISA PnP
For Plug & Play compatible devices designed for PCI
or ISA bus architecture.
Legacy ISA
For devices compliant with the PC AT bus
specification, requiring a specific interrupt.
PCI/VGA Palette Snoop
When set to Enabled, multiple VGA devices operating on different buses can
handle data from the CPU on each set of palette registers on every video
device. Bit 5 of the command register in the PCI device configuration space is
the VGA Palette Snoop bit (0 is disabled). For example, if there are two VGA
devices in the computer (one PCI and one ISA) and the:
VGA Palette Snoop
Bit Setting
Action
Disabled
Data read or written by the CPU is only directed to the PCI
VGA device’s palette registers.
Enabled
Data read or written by the CPU is directed to both the PCI
VGA device’s palette registers and the ISA VGA device’s palette registers, permitting the palette registers of both VGA
devices to be identical.
The setting must be set to Enabled if any ISA bus adapter in the system
requires VGA palette snooping.

PC Health Status
This section shows the status of your CPU, fan, warning for overall system
status.
Current System and CPU Temperature/System, Power and CPU Fan/Vcore/
3.3V/+5V/+12V/-12V/-5V/VBAT(V)/5VSB(V)
This will show the CPU/FAN/System voltage chart and FAN Speed.
CPU Critical Temperature
If the CPU temperature reaches the upper limit preset in this setting, the warning mechanism will be activated. This helps you to prevent the CPU overheat
problem.

Frequency/Voltage Control
This section describes how to set the Chassis Intrusion feature, CPU FSB
frequency, monitor the current hardware status including CPU/system
temperatures, CPU/System Fan speeds, Vcore etc. Monitor function is available only if there is hardware monitoring mechanism onboard.
CPU Ratio Selection
This setting controls the multiplier that is used to determine the internal clock
speed of the processor relative to the external or motherboard clock speed.
Auto Detect PCI Clock
This option allows you to enable/disable the feature of auto detecting the
clock frequency of the installed PCI bus. The settings are: Enabled, Disabled.
Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves. If you do not have any EMI
problem, leave the setting at Disabled for optimal system stability and
performance. But if you are plagued by EMI, setting to Enabled for EMI
reduction. Remember to disable Spread Spectrum if you are overclocking because even a slight jitter can introduce a temporary boost in clockspeed which
3-24
BIOS Setup
may just cause your overclocked processor to lock up.
CPU Host/3V66/PCI Clock
This item specifies the clock frequency of CPU host bus (FSB), Chipset,
AGP(3V66) and PCI bus and provides a method for end users to overclock
the processor accordingly. If the item shows Default, the clock frequency
will use the default value for both the CPU host bus and PCI bus.

Load Fail-Safe/Optimized Defaults
The two options on the main menu allow users to restore all of the BIOS
settings to Optimized defaults or Fail-Safe defaults. The Optimized Defaults
are the default values set by the mainboard manufacturer for the best system
performance but probably will cause a stability issue. The Fail-Safe Defaults
are the default values also set by the mainboard manufacturer for stable performance of the mainboard.
When you select Load High Performance Defaults, a message as below appears:
Pressing ‘Y’ loads the default BIOS values that enable the best system performance but may lead to a stability issue.

Supervisor/User Password
When you select this function, a message as below will appear on the screen:
Type the password, up to six characters in length, and press <Enter>. The
password typed now will replace any previously set password from CMOS
memory. You will be prompted to confirm the password. Retype the password
and press <Enter>. You may also press <Esc> to abort the selection and not
enter a password.
To clear a set password, just press <Enter> when you are prompted to enter the
password. A message will show up confirming the password will be disabled.
Once the password is disabled, the system will boot and you can enter Setup
without entering any password.
When a password has been set, you will be prompted to enter it every time you
try to enter Setup. This prevents an unauthorized person from changing any
part of your system configuration.
Additionally, when a password is enabled, you can also have AMIBIOS to
request a password each time the system is booted. This would prevent unau-

thorized use of your computer. The setting to determine when the password
prompt is required is the PASSWORD CHECK option of the ADVANCED BIOS
FEATURES menu. If the PASSWORD CHECK option is set to Always, the
password is required both at boot and at entry to Setup. If set to Setup, password prompt only occurs when you try to enter Setup.
