Hyper-threading
Hyper-threading technology allows a single physical processor to appear as several
logical processors. With this technology the operating system can better utilise the internal
processor resources, which in turn leads to increased performance. The advantages of this
technology can only be used by an operating system which supports ACPI. This setting
has no effect on operating systems which do not support ACPI.
Enabled
An ACPI operating system can use all logical processors within a physical
processor.
Disabled
An ACPI operating system can only use the
fi
rst logical processor of the physical
processor. This setting should only be used if hyper-threading technology has
not been correctly implemented in the ACPI operating system.
Limit CPUID Functions
With the aid of this function the user can reduce the CPU functions (CPUID). Some
operating systems cannot process new CPUID commands which support more than three
functions. This option should be activated for these operating systems.
Enabled
For reasons of compatibility with the operating system, only a reduced number of
CPUID functions are supported by the processor.
Disabled
All CPUID functions are supported.
Core Multi-Processing
For processors that contain several logical processors, all but one logical
processors can be deactivated.
Disabled
All but one logical processors are deactivated.
Enabled
All available logical processors are active.
CPU MC Status Clear
When a processor identi
fi
es an error, the cause is stored in a status register. Some errors can
be resolved immediately, others can lead to a system failure. Now the processor can retain
the MC (Machine Check) status until switch-off. After a reset, the BIOS can handle this CPU
MC status information during the POST phase and log the detected run-time errors.
Disabled
The CPU MCA status registers will not be reset by the BIOS.
Enabled
The CPU MCA status registers will be reset by the BIOS during the next
boot process.
Next Boot
The CPU MCA status registers will be reset one-time only by the BIOS during
the next boot process.
