Chapter 2. System-Board Features

This section includes information about system-board features. For an illustration of the system board,
see “System Board, Models 6561 and 6591” on page 12.

Microprocessor

The microprocessor in the PC 300GL (Models 6561 and 6591) is the Intel Pentium II Processor with MMX
Technology. The microprocessor features are:

Optimization for 32-bit software

Operation at a lower voltage level than previous microprocessors

64-bit microprocessor data bus

32-bit microprocessor address bus

Math coprocessor

MMX technology (boosts the processing of graphic, video, and audio data)

L2 cache integrated into the microprocessor

– 4-way set associative

– Nonblocking

– 50-percent processor speed
– Performance increase over placement of L2 cache on the system board

The microprocessor (which has a heat sink attached) plugs directly into a connector on the system board.
