FCC Compliance Statement
For US and Canadian Users
Warning!
Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15, Subpart B of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions,
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 on and off, 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 receiver.
• Connect the equipment into an outlet on a circuit different from that to
which the receiver is needed.
• Consult the dealer or an experienced radio/TV technician for help.
The connection of a non-shielded equipment interface cable to this equipment will
invalidate the FCC Certification of this device and may cause interference levels
which exceed the limits established by the FCC for this equipment.
This equipment is a Class B digital apparatus which complies with the Radio
Interference Regulations, C.R.C., c. 1374.
Cet appareil numèrique de la classe B est conformè au Règlement sur le brouillage
radioèlèctrique, C.R.C., ch. 1374.

Chapter 1 - The Big Picture
1. The Big Picture
Welcome to the ZEOS User’s Guide! The User’s Guide works with the
Getting Started manual to help keep your system running trouble free,
year after year.
This User’s Guide is divided into five chapters.
Chapter 1, The Big Picture gives an overview of a typical desktop and
tower system. It also shows the major components inside the computer
case.
Chapter 2, The Mainboard gives detailed information about your
mainboard.
Chapter 3, Using SETUP explains how to use the SETUP utility
program to customize the built-in features of your system’s BIOS (Basic
Input/Output System).
Chapter 4, Expanding Your System shows how to add components and
enhancements to your system. These include a video adapter card, a
controller card, an internal modem, a floppy drive, an IDE hard drive, a
CD-ROM drive, memory RAM SIMMs, system cache, and a new CPU.
Chapter 5, Mainboard Specifications includes your mainboard
specifications, environmental specifications, plus pin assignments for your
serial and parallel ports.
The Handy Cheat Sheet gives a short summary of some of the most
needed or most forgotten commands.
The Glossary gives short definitions of some common computer terms.

How to Open a Desktop Case
Caution:
Whenever you open the case or work inside the computer there is
danger of static electric shock. These shocks can permanently damage
your equipment. Always ground yourself by touching the system
cabinet before touching any internal component. We strongly recom-
mend using an antistatic wrist strap attached to cabinet ground.
To open a desktop case:
1. Turn off the monitor and system unit power. Unplug the AC power
cables and disconnect any other cables attached to the back of the
system unit.
2. Remove the plastic bezel from the back of the case by pulling it
away from the case.
3. Unscrew the five mounting screws at the back of the case that hold
the case cover to the system unit chassis.
4. Slide the case cover back and up. Be careful not to snag any cables
or connectors inside the case.
5. Set the case cover aside while you work on your system.
6. When through, reattach the case cover, screws, bezel, and cables in
the reverse order.
Theillustrationsopposite show the plastic bezel, screw
locations,and how to remove a desktop PC’scover.

How to Open a Tower Case
Chapter 1 - The Big Picture
Caution:
Whenever you open the case or work inside the computer there is
danger of static electric shock. These shocks can permanently damage
your equipment. Always ground yourself by touching the system
cabinet before touching any internal component. We strongly recom-
mend using an antistatic wrist strap attached to cabinet ground.
Opening a tower case is almost identical to opening a desktop case.
To open a tower case:
1. Turn off the monitor and system unit power. Unplug the AC power
cables and disconnect any other cables attached to the back of the
system unit.
2. Remove the plastic bezel from the rear of the case by pulling it
away from the case.
3. Unscrew the six mounting screws at the back of the case that hold
the case cover to the system unit chassis.
4. Slide the case cover back and up, taking care not to snag any
cables or connectors inside.
5. Set the case cover aside while you work on your system.
6. Afterwards, reattach the case cover, screws, bezel, and cables in
the reverse order.

The mainboard is the large circuit board at the bottom of the chassis. It is
the heart of your system. All of the other components inside the case work
for the mainboard. The power supply delivers electricity to the mainboard.
The disk drives, keyboard connectors, and other parts of the system unit
bring information to and from the mainboard.
The figure above shows some of the most common components inside the
computer.
