Table 38. System setup options-Virtualization menu (continued) Virtualization Support Enable OS Kernel DMA Support Allows you to control the Kernel DMA protection for both internal and external ports. This option does not directly enable DMA protection in the operating system. For operating systems that support DMA protection, this setting indicates to the operating system that the BIOS supports the feature. NOTE: This option is not available when the virtualization setting for IOMMU is disabled (VT-d/AMD Vi). By default, the Enable OS Kernel DMA Support option is enabled. NOTE: This option is provided only for compatibility purposes, since some older hardware is not DMA capable. Table 39.

The default value is set to the maximum number of cores. By default, the All Cores option is selected. Intel SpeedStep Enable Intel SpeedStep Technology Enables the computer to dynamically adjust processor voltage and core frequency, decreasing average power consumption and heat production. By default, the Enable Intel SpeedStep Technology option is enabled. C-State Control Enable C-State Control Enables or disables the ability of the CPU to enter and exit low-power state.
