Ok new to the forums, and fairly new Mac switcher. Know a lot about Windows and Linux systems and have used VMWare in the past for Linux on Windows. The problem I'm having is that just recently I've upgraded the processor in my Mac mini to a T7200 so that when Leopard is released, I'll have support for the supposed 64 bit part of the OS. I've found out that the processor supports VT-x allowing me to install a 64 bit guest OS on a 32 bit host OS. How can I enable this permenantly? I realise Mac mini's are a bit flaky on this and I've followed all the steps from this link: http://forums.parallels.com/thread3273.html. Somehow I managed to enable it by fluke and it would work once but once only after a reboot. None of the problems other users have experienced. The sleep and wake up never worked. And now I've somehow managed to stop it working. Please can someone help with some more recent info that the above link.
