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
grounding-type 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
grounding-type plug.
9. Do not allow anything to rest on the power cord. Do not locate
this product where persons will walk on the cord.

iv
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
instructions are followed. Adjust only those controls that are

14. Replace battery with the same type as the product's battery we
recommend. Use of another battery may present a risk of fire or
explosion. Refer battery replacement to a qualified serviceman.

v
15. Warning! Battery may explode if not handled properly. Do not
recharge, disassemble or dispose of in fire. Keep away from
children and dispose of used battery promptly.
16. Use only the proper type of power supply cord set (provided in
your keyboard/manual accessories box) for this unit. It should be
a detachable type: UL listed/CSA certified, type SJT, rated 6A
125V minimum, VDE approved or its equivalent. Maximum
length is 15 feet (4.6 meters).

System Introduction
System Introduction 1-1
1.1 Features
The AcerAltos 19000Pro4 is a powerful 64-bit quad-processor system
loaded with a host of new and innovative features. The system 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 AcerAltos 19000Pro4
system. Designed to work with the Orion chipset composed of a PCI
bridge and memory controller, the Pentium Pro running at 200 MHz
carries a new generation of power not present in its predecessors.
The system board has four CPU sockets to accommodate up to four
Intel Pentium Pro CPUs for a multiprocessor configuration. This
configuration doubles efficiency and reliability thereby upgrading
overall system performance. The Pentium Pro supports a wide range
of applications running under SMP network operating systems such
as WindowsNT, UNIX, NetWare, etc.
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.

1-2AcerAltos 19000Pro4 System Guide
First-level and Second-level Cache
The Pentium Pro has a 16-KB first-level and 256/512/1024-KB
second-level cache. These caches produce a high hit rate that
reduces the processor’s external memory bandwidth requirements.
Advanced Peripheral Interrupt Controller (APIC)
The APIC unit inside the CPU along with the I/O APIC unit facilitate
multiprocessor interrupt management. The APIC works with multiple
I/O subsystems where each subsystem have its own interrupts that
help minimize centralized system overhead.
Bus Controller
The bus controller integrated in the Pentium Pro CPU controls the
system bus to make it perform its functions efficiently. It ensures that
the bus serves as a reliable interconnection between one or two
CPUs, I/O bridge, and memory controllers.
