(in 8-cycle increment). The default setting is 32 (bus cycles).
Intel <R> Virtualization Technology (Available when supported by the CPU)
Select Enabled to use the feature of Virtualization Technology to allow one platform
to run multiple operating systems and applications in independent partitions, creat-

keep all CPU software visible. Select C3 to activate the Sleep State mode when the
CPU does not need to keep its cache coherent but maintains other states. Select
C4 to activate the package-level lower-power mode after each core of CPUs has
been set to C3 State in an effort to further reduce power consumption. The options
are C1, C1C2 (C1 & C2), C1C2C3 (C1, C2 & C3), and C1C2C3C4 (C1, C2, C3 &
C4). Please refer to Intel's web site for details.
