cleaning.
4. Do not use this product near water.
5. Do not place this product on an unstable cart, stand, or table. The
product may fall, causing serious damage to the product.
6. Slots and openings in the cabinet and the back or bottom are
provided for ventilation; to ensure reliable operation of the product
and to protect it from overheating, these openings must not be
blocked or covered. The openings should never be blocked by
placing the product on a bed, sofa, rug, or other similar surface.
This product should never be placed near or over a radiator or heat
register, or in a built-in installation unless proper ventilation is
provided.
7. This product should be operated from the type of power indicated
on the marking label. If you are not sure of the type of power
available, consult your dealer or local power company.
8. This product is equipped with a 3-wire grounding-type plug, a plug
having a third (grounding) pin. This plug will only fit into a groundingtype power outlet. This is a safety feature. If you are unable to
insert the plug into the outlet, contact your electrician to replace
your obsolete outlet. Do not defeat the purpose of the groundingtype plug.
iii
9. Do not allow anything to rest on the power cord. Do not locate this
product where persons will walk on the cord.
10. If an extension cord is used with this product, make sure that the
total ampere rating of the equipment plugged into the extension
cord does not exceed the extension cord ampere rating. Also, make
sure that the total rating of all products plugged into the wall outlet
does not exceed 15 amperes.
11. Never push objects of any kind into this product through cabinet
slots as they may touch dangerous voltage points or short out parts
that could result in a fire or electric shock. Never spill liquid of any
kind on the product.
12. Do not attempt to service this product yourself, as opening or
removing covers may expose you to dangerous voltage points or
other risks. Refer all servicing to qualified service personnel.
13. Unplug this product from the wall outlet and refer servicing to
qualified service personnel under the following conditions:
a. When the power cord or plug is damaged or frayed
b. If liquid has been spilled into the product
c. If the product has been exposed to rain or water
d. If the product does not operate normally when the operating

FCC Class B Radio Frequency
Interference Statement
Note:
This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to Part 15 of 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 off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
4. Consult the dealer or an experienced radio/television 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.
Notice 2:

About This Manual
Audience
This User's Manual is intended for three types of reader:
. Users of application software in a business or personal-computing
environment
. Business and technical buyers who want to develop software and hardware
packages to customize the system for a specific environment
. System designers and programmers who intend to modify the system
hardware and configure the system
Purpose and Scope
This manual tells you how to install, configure and operate the system.
In addition to giving information about the system hardware and software, it
also explains how to install optional devices and how to deal with operating
problems and error messages.
xv
Organization
This manual consists of six chapters.
Chapter 1, System Housing, describes the different parts of the system unit
such as switches, status indicators, connectors, and hardware components. It
explains how to set up and start the system. It also shows how to install
optional hardware devices. Guidelines for troubleshooting minor hardware
problems are given at the end of the chapter.
Chapter 2, System Board, describes the features and components of the system
board. It also includes jumper settings and memory configurations.
Chapter 3, 486 CPU Board, describes the features of the 486 CPU board,
CPU and second-level cache upgrade, and jumper settings.
Chapter 4, Pentium CPU Board, presents the features of the Pentium CPU
board. It explains how to upgrade to dual Pentium CPUs, adjust jumper settings,
and upgrade memory and second-level cache.
Chapter 5, Configuring the System, shows how to use the BIOS SETUP
utility to configure your system. It includes a fixed disk type table at the end
for your reference.
Chapter 6, EISA Configuration Utility, tells how to use the ECU utility
bundled with your system to configure your computer and the boards or options
you add to the system.

C h a p t e r 1
System Housing
This chapter describes the system housing features and the additional
components that can be installed. It also has instructions on installing and
removing these components.
1.1 Getting Started
The preinstallation process involves the following:
. Selecting a site
. Unpacking the components
. Positioning the system
. Moving the System
1.1.1 Selecting a Site
Consider the following when selecting a site for the system:
1. Find a place that is comfortable for you. Avoid dusty areas of extreme
temperature and humidity.
2. Cable paths should not run near equipment that might cause
electromagnetic or frequency interference such as radio transmitters,
television sets, copying machines, heaters, or air conditioners.
3. Find a location close to an electrical outlet. Avoid using extension cords.
4. Leave enough space around the system for normal air circulation.
System Housing 1-1
1.1.2 Unpacking the System
Unpack the contents of the system box and the accessory box. Save the packing
materials in case you need to ship the system in the future.
The system box contains the system with one 3.5-inch diskette drive, a SCSI
CD-ROM drive and at at least one fixed disk drive installed.
The accessory box contains the following:
. Apricot FT//ex Owner's Handbook
. Power Connection Guide
. Graphics Accelerator Card User's Guide
. System Utilities Diskette
. EISA Configuration Diskette
. SCSI Drivers Pack
. MS-DOS 6.0
. Power cord
. Keyboard
. Mouse
For your convenience, Microsoft MS-DOS is pre-installed in a small (typically
15 Mbyte) primary DOS partition on your system's first fixed disk. A DOS
mouse driver, MOUSE.SYS, is provided as part of the pre-installation. Note
that this driver is not included on the DOS installation diskettes, and should
therefore be backed up as soon as possible.
1-2 Owner's Handbook
1.1.3 Positioning the System
Arrange the feet of the system in such a way that the system is standing stably.
Figure 1-1 shows the correct position of the feet when standing the system
alone.
Figure 1-1 Standing the System Alone
System Housing 1-3
When standing the system with the fan facing the wall, leave 5 - 10 cm space
from the wall for normal air circulation, then position the feet as in Figure 12A.
When standing the system with the fan facing out, you can put the unit close
to the wall and position the feet as in Figure 1-2B.
Figure 1-2 Standing the System Against a Wall
1-4 Owner's Handbook
1.1.4 Moving the System
The system housing has a handle on top and two wheels at the base for easy
moving.
Figure 1-3 shows how to move the system.

NOTE: Be sure to close the feet of the system before
moving it.
