Virutual PC 2007 FBSD 6.3 hangs on install

[reese at adeptscience.com]

 I am trying to get Vitual PC Version 2007 to install FreeBSD as a guest 
system.  I tried first with FBSD ver. 6.3 and that failed by hanging 
saying:

Trying to mount root from ufs:/dev/md0



After looking on the web I found this mentioned in bug 
reports but did not see any fixes.


Giving up on 6.3 I downloaded an iso image of
FBSD 5.5

This time I got through the boot procedure and started a 
standard install from sysinstall.  I got the disk labled and 
partitioned to / /var /usr and a swap but when I finished 
I got a few popup screens and finally one that said

'unable to make new root file system on /dev/ad0s1a'

A few questions?

Is anyone working to fix the problem with 6.3?

Any sugestions as to what my problem might be with 5.5?


Any version of FRSD known to work with Vitual PC ver. 2007?


Does VMWare work with 6.3 and if so do I need 
VMWare Workstation or VMWare Player or ????


Cheers,
