What is your question exactly? You seem to be trying to get MacOS to work in VMWare but it won't do it with software virtualization. That means you need hardware virtualization which is only available on certain CPUs, through Intel's VT-x or VT-d technologies, or AMD's AMD-V technology. Most newer CPUs like the Core i5 and i7 or AMD's FX, or Phenom II CPUs have support for hardware virtualization. If you are running something older like a Core 2 Duo though, you won't have hardware virtualization, and you'll have to upgrade in order to get it.
If you do have a newer CPU that supports hardware virtualization, and it still isn't working, check your BIOS settings and make sure Intel VT-d or VT-x or AMD-V is enabled.
The Pentium D does not support hardware virtualization, so you're out of luck with that system. Without knowing more about your motherboard I can't really recommend a CPU upgrade, and not that many CPUs if any on LGA775 supported hardware virtualization. To do what you want you are going to have to get a new computer.
