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.
