Configuration
Allows you to enable or disable the CPU features that enhance
the performance of the system.

front-side bus (FSB) clockspeed determines the core speed
of the processor.
CPU core clock = FSB Frequency/4 x CPU multiplier
• C1E Enhanced Halt State—If enabled, CPU power
consumption is reduced when the CPU is idle. This is triggered
by the operating system executing the halt instruction.
