BIOS Setup
▶ CPU Configuration
▶ Intel Virtualization Technology
Virtualization enhanced by Intel Virtualization Technology will allow a platform
to run multiple operating systems and applications in independent partitions.
With virtualization, one computer system can function as multiple "Virtual"
systems.
▶ Active Processor Cores
This setting specifies the number of active processor cores.
▶ Execute Disable Bit
Intel's Execute Disable Bit functionality can prevent certain classes of mali-
cious "buffer overflow" attacks when combined with a supporting operating
system. This functionality allows the processor to classify areas in memory by
where application code can execute and where it cannot. When a malicious
worm attempts to insert code in the buffer, the processor disables code exe-
cution, preventing damage or worm propagation.
▶ Intel(R) SpeedStep(TM)
EIST (Enhanced Intel SpeedStep Technology) allows the system to dynam-
ically adjust processor voltage and core frequency, which can result in de-
creased average power consumption and decreased average heat produc-
tion. When disabled, the processor will return the actual maximum CPUID
input value of the processor when queried.
▶ C States
This setting controls the C-States (CPU Power states).
