1.1.3 Intelligence
Automatic CPU/Chassis Fan Off
The CPU and chassis fans will automatically turn off once the system
enters the Suspend mode.
Dual Function Power Button
Depending on the setting in the BIOS setup, this switch will allow
the system to enter the Soft-Off or Suspend mode.
External Modem Ring-on
The Modem Ring-on feature allows the system that is in the
Suspend mode or Soft Power Off mode to wake-up/power-on to
respond to incoming calls.
Note:
This feature supports external modem only.
RTCTimer to Power-on the System
The RTC installed on the system board allows your system to
automatically power-on on the set date and time.
Wake-On-LAN Ready
The Wake-On-LAN function allows the network to remotely wake
up a Soft Power Down (Soft-Off) PC.Your LAN card must support
the remote wakeup function.
Important:
The 5VSB power source of your power supply must support
≥ 720mA.
Wake-On-Keyboard/Wake-On-Mouse
This function allows you to use the keyboard or mouse to power-on
the system. Refer to “Jumper Settings for Wake-On-Keyboard/Wake-
On-Mouse” in Chapter 2 and “Keyboard/Mouse Power On” in the
Integrated Peripherals setup of the Award BIOS in Chapter 3 for
more information.

Important:
• The power button will not function once a keyboard
password has been set in the “KB Power On Password”
field of the Integrated Peripherals setup.You must type the
correct password to power-on the system.
• The 5VSB power source of your power supply must
support ≥ 720mA.

Hardware Installation
2.2 System Memory
The system board is equipped with three 168-pin DIMM (Dual In-
line Memory Module) sockets that support x64/x72 unbuffered or
registered PC SDRAM DIMM, 3.3V.
PC SDRAM (Synchronous Dynamic Random Access Memory) uses a
fast memory interface technology that includes using the clock on the
chip to synchronize with the CPU clock so that the timing of the
memory chips and the timing of the CPU are synchronized. This
saves time during transmission of data, subsequently increasing
system performance.
Warning:
Electrostatic discharge (ESD) can damage your system board,
processor, disk drives, add-in boards, and other components. Perform
the upgrade instruction procedures described at an ESD
workstation only. If such a station is not available, you can provide
some ESD protection by wearing an antistatic wrist strap and
attaching it to a metal part of the system chassis. If a wrist strap
is unavailable, establish and maintain contact with the system
chassis throughout any procedures requiring ESD protection.

2.2.1 Installing the DIM Module
A DIM module simply snaps into a DIMM socket on the system
board. Pin 1 of the DIM module must correspond with Pin 1 of the
socket.
1. Pull the “tabs” which are at the ends of the socket to the side.
2. Position the DIMM above the socket with the “notches” in the
module aligned with the “keys” on the socket.
3. Seat the module vertically into the socket. Make sure it is
completely seated.The tabs will hold the DIMM in place.

2.4 Jumper Settings for the CPU’s Front Side Bus
Jumper JP2
CPU’s Front Side Bus Select
The default setting of jumper JP2 is
Auto - the system will automatically
run according to the FSB of the
processor. The “100MHz” setting
(1-2-3 Off) is reserved for future
100MHz FSB processors. Refer to
the figure on the next page.
Warning:
If your system is installed with
a 66MHz FSB processor, do
not move the jumper cap
from its default setting which
is pins 1 and 2 On; otherwise
your system will not boot.
Jumper JP2’s settings are shown below.

Jumper JP3
Clear CMOS Data
If, for some reason, the CMOS data
becomes corrupted or you forgot
the supervisor/user/keyboard
password, the system can be
reconfigured with the default values
stored in the ROM BIOS. To load
the default values, power off your
system and unplug the power
cord. Set JP3 pins 2 and 3 to On.
Wait for a few seconds and set JP3
back to its default setting, pins 1
and 2 On. You may now plug the
power cord and power-on your
system.

Jumper JP1
Wake-On-Keyboard/Wake-On-Mouse
The system board supports the Wake-
On-Keyboard/Wake-On-Mouse function.
This function allows you to use the
keyboard or mouse to power-on the
system. By default, JP1 is disabled.To use
this function, set JP1 to 2-3 On.
“Keyboard/Mouse Power On” in the
Integrated Peripherals setup of the
Award BIOS must be set accordingly.
Refer to chapter 3 for details.
Warning:
1. If JP1 was previously enabled
with a password set in the
“KB Power On Password” field, and now you wish to disable
the Wake-On-Keyboard (password) function, make sure to
set the “Keyboard/Mouse Power On” field to Disabled prior
to setting JP1 to disabled. You will not be able to boot up
the system if you fail to do so.
2. The power button will not function once a keyboard
password has been set in the “KB Power On Password”
field of the Integrated Peripherals setup.You must type the
correct password to power-on the system.
3. The 5VSB power source of your power supply must
support ≥ 720mA (minimum).

2.7.2 PS/2 Mouse and Keyboard Ports
The PS/2 mouse port uses IRQ12. If
a mouse is not connected to this port,
the system will reserve IRQ12 for
other expansion cards.
Warning:
Make sure to turn off your
computer prior to connecting or
disconnecting a mouse or
keyboard. Failure to do so may
damage the system board.
2.7 Connecting the Ribbon Cables and Wires of
the Ports and Connectors
2.7.1 Serial Ports
The built-in serial ports are RS-232C
asynchronous communication ports
with 16C550A-compatible UARTs that
can be used with modems, serial
printers, remote display terminals, and
other serial devices. You can set the
serial ports’ I/O address in the
Integrated Peripherals setup of the
Award BIOS.

2.7.3 Parallel Ports
The system board has a standard
printer port for interfacing your PC
to a parallel printer. It supports SPP,
ECP and EPP modes. You can set the
port’s mode in the Integrated Periph-
erals setup of the Award BIOS.
2.7.4 Floppy Disk Controller
The system board is equipped with a shrouded floppy disk header
that supports two standard floppy disk drives. To prevent
improper floppy cable installation, the shrouded floppy disk header
has a keying mechanism.The 34-pin connector on the floppy cable
can be placed into the header only if pin 1 of the connector is
aligned with pin 1 of the header. You may enable or disable this
function in the Integrated Peripherals setup of the Award BIOS.

Hardware Installation
2.7.5 IDE Hard Disk Interface
The system board is equipped with
two shrouded PCI IDE headers that
will interface four Enhanced IDE
(Integrated Drive Electronics) hard
disk drives. To prevent improper
IDE cable installation, each shrouded
PCI IDE header has a keying
mechanism. The 40-pin connector
on the IDE cable can be placed into
the header only if pin 1 of the
connector is aligned with pin 1 of
the header.
Connecting the Floppy Disk Cable
1. Install the 34-pin header
connector into the shrouded
floppy disk header (J4) on the
system board. The colored edge
of the ribbon should be aligned
with pin 1 of J4.
2. Install the other 34-pin header
connector(s) into the disk
drive(s). Align the colored edge
of the daisy chained ribbon cable
with pin 1 of the drive edge
connector(s). The end-most
connector should be attached to
the drive you want to designate
as Drive A.
