Hi, Was wondering if anyone with a 2008 Mac Pro is running Windows 7 and is using XP Mode. On my system, XP Mode refuses to run, saying that virtualization is shut off in the BIOS. What's weird is that this only happens if i cold boot into W7 by holding down the Option key. If I boot into OS X, virtualization (with VirtualBox) works fine. If I boot into OS X, then reboot into W7, XP Mode suddenly works again. Anyone else seeing this? Could this be a problem with my Mac Pro? Thanks!
