I recently purchased an Inspiron 6400 with an Intel Dual Core 2 chipset. I was using Virtual PC 2007 to setup a test server config when I noticed I could not enable virtulization. I double checked the BIOS and did not see any entry that would allow me to enable virtualization. Did I miss the setting in BIOS or is there a BIOS upgrade I need to install to enable this feature? Turning on hardware virtualization will increase my Virtual PC image 15% or more.
