Max CPUID Value Limit
When CPUID instruction is executed, newer CPU may return a value greater
than 3 which causes certain problem with specific operating systems. Ena-
bling "Max CPUID Value Limit" will limit the returned value to 3 and less to get rid
of the problem. The problem is not seen with Windows series operating sys-
tems so the default is set to disabled for it.
Virtualization Technology (Only for the CPU with Dual Core)
Virtualization Technology will allow a platform to run multiple operating sys-
tems and applications in independent partitions. With virtualization, one compu-
ter system can function as multiple “virtual” systems. With enhancements to
Intel’s various platforms, Intel Virtualization Technology can improve the ro-
bustness and performance of today’s software-only solutions.Settings:
[Enabled], [Disabled].
Execute Disable Bit
Execute-Disable Bit capability is a robust hardware feature, detectable using
the CPUID instruction, that protects against malicious software executing code
on IA-32 systems.Settings: [Enabled], [Disabled].
Hardware Prefetcher
This item allows you to to enable/disable the hardware prefetcher, or in other
words – hardware prefetch mechanism.Settings: [Enabled], [Disabled].
Adjacent Cache Line Prefetch
This item allows you to enable/disable the adjacent cache line prefetch mode.
When disabled, only one 64 byte line from the 128 byte sector is prefetched
(which contains the requested data). When enabled – both lines are prefetched
no matter whether they have or have not the requested data. Setting options:
[Enabled], [Disabled].
Hyper-Threading Technology
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 sup-
port HT Function, or unreliability and instability may occur.
