As we go to forward with implementing Windows 7 Ultimate for our clients, one of the first things we check for is the ability to have Intel Virtualization (VT) enabled in the BIOS.
The new version of Virtual PC that XP Pro Mode runs on will require that VT or AMD’s equivalent be enabled in the BIOS.
By default when we do find the VT settings exposed in the BIOS, it looks as though laptop manufacturers are leaving the settings disabled out of the box:
When implementing Windows 7 Ultimate or Windows 7 Enterprise with the intent of running XP Pro Mode, the BIOS level settings need to be checked.
Note that this particular Lenovo ThinkPad T500 has the Centrino 2 vPro chipset. Even then, finding the settings shown in the BIOS depends on the manufacturer of the laptop.
We have seen some Centrino 2 vPro series laptops where the settings were not exposed. We have one here in the shop, but have not had the chance to unpack it and load Windows 7 Ultimate and the XP Pro Mode RC to verify that the settings are enabled by default.
