Chapter 2. System Board Features Chapter 2. System Board Features This section includes information about system board features. To view an illustration of the system board, see "System Board" on page 14. For a list of features provided with the PC 365, see "Hardware Features" on page 1. Microprocessor The primary microprocessor in the PC 365 is the Intel P6, called the Pentium Pro. A voltage regulator circuit on the system board provides the required power for the primary microprocessor. The Pentium Pro microprocessor features: Dynamic execution technology Multiprocessing support Optimization for 32-bit software Internal L2 cache - 4-way set associative - Non-blocking - 1 GB/second bandwidth communication with the microprocessor core 64-bit data bus 36-bit address bus Upgradable to future Overdrive microprocessors Math coprocessor Note: Refer to http://www.intel.com for more information on the Intel Pentium Pro microprocessor. The microprocessor plugs directly into a zero-insertion-force (ZIF) socket (socket 8) on the system board. Socket 8 allows for a performance upgrade. After an upgrade is installed, the internal speed of the primary microprocessor is updated by setting switches on the system board (see "Switches" on page 16). Dual Processing Support The combined technologies of the system board and the microprocessor provide support for dual processing. The dual processing configuration is known as symmetric multiprocessing (SMP). The PC 365 provides: Power-supply margins for dual processing Thermal margins for dual processing A multiprocessor interrupt controller (for advanced programmable interrupt controls (APIC) on the system board) Code for APIC initialization On the system board, directly beside the primary microprocessor, a second socket 8 is provided for installing a second Pentium Pro microprocessor. Also, sockets are provided for connecting a voltage-regulator module which supplies power to the second microprocessor, and a fan (part of a fan-sink assembly), which helps cool the second microprocessor. To locate these connectors, see "System Board" on page 14. An upgrade kit for the PC 365 is an available option from IBM. The upgrade kit includes a Pentium Pro microprocessor, a fan-sink assembly, a voltage-regulator module, and instructions for installation. 4 © Copyright IBM Corp. 1996, 1997

System Board Features
This section includes information about system board features.
To view an illustration of the system
board, see “System Board” on page
14.
For a list of features provided with the PC
365, see “Hardware Features” on page
1.
Microprocessor
The primary microprocessor in the PC
365 is the Intel P6, called the Pentium Pro.
A voltage regulator
circuit on the system board provides the required power for the primary microprocessor.
The Pentium Pro
microprocessor features:
±
Dynamic execution technology
±
Multiprocessing support
±
Optimization for 32-bit software
±
Internal L2 cache
–
4-way set associative
– Non-blocking
–
1 GB/second bandwidth communication with the microprocessor core
±
64-bit data bus
±
36-bit address bus
±
Upgradable to future Overdrive microprocessors
±
Math coprocessor
Note:
Refer to
for more information on the Intel Pentium Pro microprocessor.
The microprocessor plugs directly into a zero-insertion-force (ZIF) socket (socket 8) on the system board.
Socket 8 allows for a performance upgrade.
After an upgrade is installed, the internal speed of the
primary microprocessor is updated by setting switches on the system board (see “Switches” on page
16).
Dual Processing Support
The combined technologies of the system board and the microprocessor provide support for dual
processing.
The dual processing configuration is known as symmetric multiprocessing (SMP).
The
PC 365 provides:
±
Power-supply margins for dual processing
±
Thermal margins for dual processing
±
A multiprocessor interrupt controller (for advanced programmable interrupt controls (APIC) on the
system board)
±
Code for APIC initialization
On the system board, directly beside the primary microprocessor, a second socket 8 is provided for
installing a second Pentium Pro microprocessor.
Also, sockets are provided for connecting a
voltage-regulator module which supplies power to the second microprocessor, and a fan (part of a fan-sink
assembly), which helps cool the second microprocessor.
To locate these connectors, see “System Board”
on page
14.
An upgrade kit for the PC
365 is an available option from IBM.
The upgrade kit includes a Pentium Pro
microprocessor, a fan-sink assembly, a voltage-regulator module, and instructions for installation.
