CPU Configuration
This section is used to configure the CPU. It will also display the detection of CPU information.
Hyper-threading
Enable this field for Windows XP and Linux which are optimized for Hyper-Threading
technology. Select disabled for other OSes not optimized for Hyper-Threading technol-
ogy. When disabled, only one thread per enabled core is enabled.
Active Processor Cores
Number of cores to enable in each processor package.
Limit CUPID Maximum
The CPUID instruction of some newer CPUs will return a value greater than 3. The
default is Disabled because this problem does not exist in the Windows series operat-
ing systems. If you are using an operating system other than Windows, this problem
may occur. To avoid this problem, enable this field to limit the return value to 3 or less
than 3 .
Intel Virtualization Technology
When this field is set to Enabled, the VMM can utilize the additional hardware
capabilities provided by the Intel Virtualization technology. A full reset is required to
change the setting.
Enabled for Windows XP
and Linux (OS optimized
for Hyper-Threading
Technology) and Disabled
for other OS (OS not
optimized for
Hyper-Threading
Technology). When
Disabled only one thread
per enabled core is
enabled.
