Chapter 2.
System board features
This section includes information about system board features.
For an illustration of
the system board, see
“Physical layout” on page 14.
Intel Pentium III microprocessor with MMX technology
PC 300 GL personal computer types 6563, 6564, and 6574 and PC 300 PL personal
computer type 6565 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.
Chip set control
The chip set design is the interface between the microprocessor and the
following:
•
Memory subsystem
•
PCI bus
•
IDE bus master connection
•
High performance, PCI-to-ISA bridge
•
USB ports
•
SMBus
•
Enhanced DMA controller
•
Real-time clock (RTC)
System memory
The maximum amount of system memory the computer can physically accommodate
is 1 GB total.
The amount of system memory factory-preinstalled varies by model.
