Use BIOS version 3.03 or later for best compatibility and performance with VA 2.0 and VA 2.6. Intel Virtualization Technology must be enabled in F10 Setup before a VA can be launched. VT is disabled by default in F10 Setup. A VA can be installed with VT enabled or disabled, although some VA installers may warn users that VT is disabled during installation. If VT is disabled during installation, enter F10 Setup and enable VT after the installation is complete. There are two kinds of Intel Virtualization Technology: VTx and VTd. Intel Virtualization Technology for IA-32 processors (VTx) deals with virtualization at the processor level. This must be enabled for a VA to function. Virtualization Technology Directed I/O (VTd) is an extension of VTx and deals with virtualization at the chipset level. VTd provides the capability to control DMA accesses and direct them to specific domains which are regions in physical memory. All Core 2 Duo processors support VTx. More advanced versions of Core 2 Duo also support VTd in addition to VTx. Depending on which VT is supported by the processor, one or both options may appear in F10 Setup. 3
