FCC and DOC Statement on Class B
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a residential
installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio
communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures:
 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and the receiver.
 Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
 Consult the dealer or an experienced radio TV technician for
help.

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. Set JP1 pins 1 and 2
to On.Wait for a few seconds
and set JP1 back to its default
setting, pins 2 and 3 On. You
may now power-on your
system.

2.5 Jumper Settings for SDRAM Clock (DIMM)
Jumper JP2
SDRAM Clock
JP2 is used to set the SDRAMs
clock according to the CPU
clock or AGP clock. If you are
using PC SDRAM DIMMs, it is
recommended that you set the
SDRAM clock according to the
CPU clock (2-3 On).This setting
will provide better system
performance specially when used
with 75/83/95/100MHz
processors. However, if you
encounter compatibility problems
with PC SDRAM DIMMs or you are using EDO/SDRAM DIMMs,
set the SDRAM clock according to the AGP clock (1-2 On).
2-3 On:
SDRAM CLK = CPU CLK
1-2 On:
SDRAM CLK = AGP CLK

Hardware Installation
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 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.
Connecting the Serial Ports
Two serial port cables
mounted on a card-edge
bracket are provided with the
system board. Connect one
serial port cable to connector
J6 for COM 1 primary serial
port and the other serial port
cable to connector J5 for the
COM 2 secondary serial port.
Make sure the colored stripes
on the ribbon cables are
aligned with pins 1 of
connectors J5 and J6. Mount
the card-edge bracket to the
system chassis.

18
2Hardware Installation
2.6.2 PS/2 Mouse Port
The PS/2 mouse port is a 6-pin connector on the system board.
Attach the 6-pin mouse port cable, which is mounted on a card-
edge bracket, to connector J1. Make sure the red wire on the PS/2
mouse connector is aligned with pin 1 of connector J1. Mount the
card-edge bracket to the system chassis.

2.6.3 Parallel Port
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.
Connecting the Parallel Printer Port
Attach the DB-25 printer port
cable to connector J7 on the
system board. Make sure the
colored stripe on the ribbon
cable aligns with pin 1 of J7.
Use a small nutdriver to
mount the cable into a DB-25
cutout in the system chassis. If
your printer port cable is
attached to a card-edge
bracket, connect the cable to
connector J7 on the system
board and mount the card-edge bracket to the system chassis.

Hardware Installation
2.6.4 Floppy Disk Drive Controller
1. Install the 34-pin header
connector into the shrouded
floppy disk header (J8) on the
system board. The colored
edge of the ribbon should be
aligned with pin 1 of connector
J8.
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 J9). 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 J10).
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.

20
2Hardware Installation
2.6.6 Universal Serial Bus Ports
The system board is equipped with two headers, at locations J2 and
J3 on the system board, for external USB ports. USB allows data
exchange between your computer and a wide range of
simultaneously accessible external Plug and Play peripherals.
You must have the proper drivers installed in your operating system
to use these ports. Refer to your operating systems manual or
documentation.
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.
