Your PC has a Pentium 4 processor.


No Pentium 4 processors support VT, which is why you can't find such a BIOS setting in the BIOS.


OS Security (some models)
NOTE: An OS Security selection is in effect only if the processor and operating system being used comprehend and utilize the security feature.
● Data Execution Prevention (some models) (enable/disable) Helps prevent OS security breaches.
● OS Management of Embedded Security Device (enable/disable). Enabling this option allows the OS the ability to manage the Embedded Security Device.
● Reset of Embedded Security Device though OS (enable/disable). A Setup Password is required to change this setting. Enabling this option allows the OS the ability to reset the Embedded Security Device back to its factory defaults.
● Virtualization Technology (some models) (enable/disable). Changing this setting requires turning the computer off and then back on.


You need one of the supported core 2 duo processors for VT.


See page 8 of the quickspecs below for the supported C2D processors...
