Chapter 2. System board features
This section includes information about system board features. For an illustration of
the system board, see “System board” on page 8.
Microprocessors
Some models come with an Intel Pentium III microprocessor and others come with an
Intel Celeron microprocessor.
More information on these microprocessors is available at http://www.intel.com on
the World Wide Web.
Intel Pentium III microprocessor with MMX technology
Some models come with an Intel Pentium III microprocessor. The microprocessor has
an attached heat sink which plugs directly into a connector on the system board.
More information on this microprocessor is available at http://www.intel.com on the
World Wide Web.
Features
The features of the Pentium III microprocessor are as follows:
• Optimization for 32-bit software
• Operation at a low voltage level
• Intel microprocessor serial number
• 64-bit microprocessor data bus
• 100-133 MHz front-side bus (FSB)
• Math coprocessor
• Internet Streaming SIMD extensions
• MMX technology, which boosts the processing of graphic, video, and audio data
L2 Cache
The Pentium III microprocessor provides up to 512 KB L2 cache. The L2 cache error
corrected code (ECC) function is automatically enabled if ECC memory is installed. If
nonparity memory is installed, the L2 cache is non-ECC.
Intel Celeron microprocessor
Some models come with an Intel Celeron microprocessor. The microprocessor has an
attached heat sink which plugs directly into a connector on the system board.
More information on this microprocessor is available at http://www.intel.com on the
World Wide Web.
Features
The features of the Celeron microprocessor are as follows:
• Intel microprocessor serial number
• Dynamic Execution technology
