Well … hours later … I almost have it working!  I was able to
get Beta 1 of Longhorn – Windows Vista – installed in Virtual PC. 
I just added the VPC Additions to get my video driver working. 
I’m going to shut down and save the image … it appears to be good
enough to have a decent installation to work with.

I’ll probably check it out further and play with it over the weekend as I have some time …
