CPU Configuration Submenu
Use this submenu to apply alternate settings to the CPU. Normally, you do
not need to modify these settings, as the factory default settings provide the
most compatible and optimal configuration possible.
• Core Multi-Processing Controller—This setting specifies whether
or not the second core of the processor is enabled or disabled. The
default value is Enabled.
• CPU Virtualization—This setting determines whether the Intel VT-x
virtualization support is enabled or disabled. A virtual machine
monitor (VMM) can utilize the additional hardware capabilities
provided by the VT-x processor extensions. The default value is
Enabled.
• Processor Type, Speed, and Number of Cores—These values
indicate the type of processor used in the NI PXI-8108 controller,
the speed of the processor, and the number of processor cores.
Video Configuration Submenu
Use this submenu to apply alternate settings to the video configuration.
Normally, you do not need to modify these settings, as the factory default
settings provide the most compatible and optimal configuration possible.
• Primary Display—This setting specifies which video adapter the
BIOS should use as the primary adapter if more than one is present. To
use an external video adapter as the primary graphics adapter, choose
Add-in PCI Video. The default value is Onboard Video.
• Total Graphics Memory—This setting specifies the amount of
system memory to allocate as graphics memory for use by the onboard
video device. The default value is 256 MB.
• DDC Routing—This setting determines how the monitor DDC is
routed. Use this setting to select whether or not the DDC is routed for
an analog monitor or a DVI monitor. In order to use a DVI monitor, this
setting must be set to DVI. An analog monitor, however, will function
with this option set to either Analog or DVI. The DDC communication
path is only enabled when set to Analog for an analog monitor, so
certain advanced features of your analog monitor may only be enabled
when routing DDC to Analog. The default setting is DVI.
