BIOS Setup MS-9A76
▶ 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 malicious
“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 execution,
preventing damage or worm propagation.
▶ Hyper-Threading
The processor uses Hyper-Threading technology to increase transaction rates
and reduces end-user response times. The technology treats the two cores
inside the processor as two logical processors that can execute instructions
simultaneously. In this way, the system performance is highly improved. If
you disable the function, the processor will use only one core to execute the
instructions. Please disable this item if your operating system doesn’t support
HT Function, or unreliability and instability may occur.
▶ C-States
C-state performance indicates the ability to run the processor in lower
power states when the PC is idle. This setting enables/disables the C-State
Configuration for power saving purposes.
