Thanks for that info, the reason I still need windows is to access a
couple of usb devices that only have windows support.  It looks like
VB is not an issue for me.

That is not an option unfortunately.  I have for the moment moved my
existing disks over to the new mother board and as I feared XP will
not boot at all.  It seems I may have to re-install XP from scratch on
the new disk when it arrives.  At least I do not need network access
from XP so I do not need all the overheads of virus scanners and so
