Introduction
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.
Notice:
1. The changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority
to operate the equipment.
2. Shielded interface cables must be used in order to comply with
the emission limits.

Static Electricity Precautions
It is quite easy to inadvertently damage your PC, system board,
components or devices even before installing them in your system
unit. Static electrical discharge can damage computer components
without causing any signs of physical damage. You must take extra
care in handling them to ensure against electrostatic build-up.
1. To prevent electrostatic build-up, leave the board in its anti-static
bag until you are ready to install it.
2. Wear an antistatic wrist strap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of
the components, contacts or connections.
5. Avoid touching the pins or contacts on all modules and connectors. Hold modules or connectors by their ends.
Important:
Electrostatic discharge (ESD) can damage your processor,
disk drive 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.
Safety Measures
To avoid damage to the system:
• Use the correct AC input voltage range
..
..
.
To reduce the risk of electric shock:
• Unplug the power cord before removing the system chassis
cover for installation or servicing. After installation or servicing,
cover the system chassis before plugging the power cord.
Battery:
• Danger of explosion if battery incorrectly replaced.
• Replace only with the same or equivalent type recommend
by
the manufacturer.
• Dispose of used batteries according to local ordinance.

Floppy Disk Drive Connector
The floppy disk drive connector supports a standard floppy disk
drive. To prevent improper floppy cable installation, the 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.
Connecting the Floppy Disk Drive Cable
Install one end of the floppy disk drive cable into the floppy disk
connector on the system board and the other end connector to the
floppy drive. Pin 1 of the cable must align with pin 1 of the connector.
Note:
FDD and LPT share the same channel therefore you can only
use one device at a time. Even when you are using one device
only, please do not connect a device to the other connector.
Use JP2 to select between using FDD and LPT. FDD is internally fixed in Slave mode.

IDE Disk Drive Connectors
The system board is equipped with two 40-pin IDE connectors for
connecting up to 4 IDE drives. To prevent improper IDE cable installation, the IDE connector has a keying mechanism. The connector on
the IDE cable can be inserted into the IDE connector only if pin 1
of the cable connector is aligned with pin 1 of the IDE connector.
Each IDE connector supports 2 devices, a Master and a Slave. Use
an IDE ribbon cable to connect the drives to the system board. An
IDE ribbon cable have 3 connectors on them, one that plugs into an
IDE connector on the system board and the other 2 connects to
IDE devices. The connector at the end of the cable is for the Master
drive and the connector in the middle of the cable is for the Slave
drive.
Note:
We do not recommend using IDE devices and CF card at the

Install one end of the IDE cable into IDE1 on the system board and
the other connectors to the IDE devices.
Note:
Refer to your disk drive user’s manual for information about
selecting proper drive switch settings.
Adding a Second IDE Disk 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.
The system board supports Enhanced IDE or ATA-2, ATA/33,
ATA/66 and ATA/100 hard drives. We recommend that you use
hard drives 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.
