2.2 System Memory
2.3 Processor
2.3.1 Using One Processor
If you are using one processor only,
please take note of the following:
1. Make sure to install the processor
into the P2-1 slot. If it is installed
in the other slot (P2-2), the
following will occur.
 The system health conditions
will be inaccurately monitored
thus causing unreliable warning
messages to appear.
 You will encounter problems with some operating systems.
2. Install the P2TC GTL+ bus terminator card (included in the
system board package) into the P2-2 slot. You will not be able
to boot the system without the terminator card.
2.3.2 Using Two Processors
If you are using two processors, make sure to install processors with
similar Front Side Bus (FSB) frequency, otherwise the warning
message 2 CPUs with different Front Side Bus frequency will
appear on the screen.

12
Hardware Installation
2.3.3 Setting the CPU Frequency
Everytime you replace or install a new processor, make sure to set
its CPU frequency in the CPU Frequency field of the CPU/Chipset
Setup. If you fail to do so, the message CPU not setup yet will
appear.
If the frequency set in the CPU Frequency field is incorrect, the
following circumstances may occur :
1. The warning message CPU frequency doesnt match SETUP
value will appear. Reset the frequency in the CPU Frequency
field for the system to work properly.
2. The system will not boot. Follow the steps in section 2.5 (Jumper
Settings for Ratio) to boot-up the system with the correct
settings.
The BIOS also allows you to manually set the Front Side Bus
frequency and core ratio of the processor in the CPU/Chipset Setup.
However, if these settings are incorrect, your system will not boot.
Please follow the steps below to boot-up the system.
1. Power-off the system.
2. Now power-on the system and press the <Ins> key at the
same time. This should allow you to boot-up the system. If it fails
to boot-up, please follow steps 1 to 9 in section 2.5 (Jumper
Settings for Ratio) of this chapter.
For more information on setting the processor, please refer to the
CPU/Chipset Setup section in Chapter 3 of this manual.

2.4 Jumper Settings for Clearing CMOS Data
Jumper JP6
Clear CMOS Data
If, for some reason, the CMOS
data becomes corrupted, 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 JP6
pins 2 and 3 to On. Wait for a
few seconds and set JP6 back to
its default setting, pins 1 and 2
On.You may now plug the power
cord and power-on your system.

incorrectly set in the BIOS. Please
follow the steps below to boot-up
the system with the correct
settings.
1. Power-off your system.
2. Set JP7 to On.
3. Now power-on your system.
After the memory test, press <Del> to enter the Award BIOS
setup utility.
4. Select CPU/Chipset Setup and press <Enter>.
5. Set the appropriate speed of the processor in the CPU
Frequency field. Refer to the CPU/Chipset Setup section in
Chapter 3 of this manual for more information.
6. Press <Esc> to return to the main menu of the Award BIOS
setup utility. Select Save & Exit Setup and press <Enter>.
7. Type <Y> and press <Enter>.
8. Power-off your system.

2.6 Connecting the Ribbon Cables and Wires of
the Ports and Connectors
2.6.1 Serial Ports
The built-in serial ports are RS-
232C asynchronous com-munication
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 Periph-
erals setup of the Award BIOS.
2.6.2 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.

Hardware Installation
2.6.3 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
Peripherals setup of the Award
BIOS.
2.6.4 Floppy Disk Controller
1. Install the 34-pin header
connector into the shrouded
floppy disk header (J16) on
the system board. The colored
edge of the ribbon should be
aligned with pin 1 of J16.
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.

2.6.5 IDE Hard Disk Interface
1. If you are connecting two hard
drives, install the 40-pin
connector of the IDE cable
into the primary shrouded IDE
header (connector J18). If you
are adding a third or fourth
IDE device, install the 40-pin
connector of the other IDE
cable into the secondary
shrouded IDE header
(connector J19).
2. Install the other 40-pin header
connector(s) into the device with the colored edge of the ribbon
cable aligned with pin 1 of the drive edge connector(s).
Note:
Refer to your disk drive users manual for information about
selecting proper drive switch settings.
Adding a Second IDE Hard Drive
When using two IDE drives, one must be set as the master and the
other as the slave. Follow the instructions provided by the drive
manufacturer for setting the jumpers and/or switches on the drives.
We recommend that you use Enhanced IDE or ATA-2, ATA-3 and
Ultra DMA hard drives be from the same manufacturer. In a few
cases, drives from two different manufacturers will not function
properly when used together. The problem lies in the hard drives, not
the system board.
Important:
If you encountered problems while using an ATAPI CD-ROM
drive that is set in Master mode, please set the CD-ROM drive
to Slave mode. Some ATAPI CD-ROMs may not be recognized
and cannot be used if incorrectly set in Master mode.

2.6.6 USB Ports
You must have the proper drivers
installed in your operating system to
use these ports. Refer to your
operating systems manual or
documentation.
2.6.7 IrDA Connector
The system board is equipped with an IrDA connector for wireless
connectivity between your computer and peripheral devices. The
IRDA (Infrared Data Association) specification suppor ts data
transfers of 115K baud at a distance of 1 meter. Connect your IrDA
cable to connector J15 on the system board. Set UART2 Mode
Select in the Integrated Peripherals setup of the Award BIOS to the
type of IrDA standard supported by your device. You must have the
proper drivers installed in your operating system to use this
connector. Refer to your operating systems manual or
documentation.
