FSB Frequency Select Signals (BSEL[2:0])

The BSEL[2:0] signals are used to select the frequency of the processor input clock
(BCLK[1:0]).
frequency associated with each combination. The required frequency is determined by
the processor, chipset, and clock synthesizer. All agents must operate at the same
frequency.

frequency (selected by a 200 MHz BCLK[1:0] frequency). The Intel
core processor E6000 series operates at a 1066 MHz FSB frequency (selected by a
266 MHz BCLK[1:0] frequency). Individual processors will only operate at their
specified FSB frequency.
