I decided to try and build a Macintosh running Tiger using my old AMD Athlon. But before I do, I decided to try using VMWare to test out my MacOS X install on VMWare. I downloaded JaS.10.4.8.AMD.Intel.SSE2.SSE3.ISO and everything installed correctly. However when I go to boot it tries with the network card and then tells me no OS detected. Here is a pcture of the VMWare screen.
