6A 125V minimum, VDE approved or its equivalent. Maximum
length is 15 feet (4.6 meters).
15. The computer uses a safety ground and must be earthed.
The system unit AC power cord is its ‘disconnect device’. Ensure
that the system unit is positioned close to the AC power outlet
and that the plug is easily accessible. The power cord packed
with the computer complies with the safety standards applicable
in the country in which it is first sold. Use only this power cord. Do
not substitute a power cord from any other equipment.
To prevent fire and electric shock, do not expose any part of the
computer to rain or moisture and turn off the computer and
unplug all power cords before moving or cleaning the system unit,
or removing the system top cover.
16. Any CD-ROM drive fitted in this system is classified as a CLASS
1 LASER PRODUCT according to IEC825 Radiation Safety of
Laser Products (Equipment Classification: Requirements and
User's Guide). The CLASS 1 LASER PRODUCT label is located
on the rear of the system unit.
It will be in high visibility colours and bear the details shown
above.
Use the CD-ROM drive only as described in this manual. Failure
to do so may result in exposure to hazardous radiation.
17. When positioning the system unit, monitor and keyboard, take
into account any local or national regulations relating to
ergonomic requirements.

vi
18. This product complies with the European safety standard
EN60950 and when applicable, will include the national
deviations for the country in which it is sold.

Procedure:
Note: Any ancillary equipment using an AC power supply cable
should be earthed.
The power supplies in the computer and the monitor are correct
for the country in which the system is first sold. Do not alter any
switch settings on the rear of the system. If you wish to use the
computer in another country it may not be suitable, contact your
supplier or an authorised Apricot dealer.
• Before connecting up any parts of the system, ensure that
the AC supply is switched off or disconnected.
• First connect up the keyboard, mouse, monitor signal cable,
and audio cables as appropriate.

viii
• Connect up all AC cables. (System to supply, system to
monitor, all related peripherals.) Then switch on or connect
the AC supply.
• Switch on the monitor first, then the computer followed by
the peripherals, such as printer or speakers.
• If the monitor AC lead is connected to the computer AC
outlet, when you come to switch off, the computer
power button will switch off the monitor at the same
time.

System Introduction
System Introduction 1-1
1.1 Features
This powerful 64-bit dual-processor system is loaded with a host of
new and innovative features. It offers a new standard for flexible
productivity ideal for local area networks and multiuser server
environments.
1.1.1 Intel Pentium Pro Microprocessor
The Intel Pentium Pro CPU is the heart of the system. Designed to
work with the Orion chipset composed of a PCI bridge and memory
controller, the Pentium Pro running at up to 200 MHz carries a new
generation of power not present in its predecessors.
The system board has two CPU sockets to accommodate up to two
Intel Pentium Pro CPUs for a dual-processor configuration. This
configuration doubles efficiency and reliability thereby upgrading
overall system performance. The Pentium Pro supports a wide range
of applications running under operating systems such as DOS,
Windows, WindowsNT, OS/2, UNIX, and NetWare.
The CPU also incorporates the first-level (L1) and second-level (L2)
caches, the advanced peripheral interrupt controller (APIC), and the
system bus controller. Figure 1-1 shows the CPU architecture.
