Thanks for the fast reply, Pete.

It's actually 6.2-RELEASE/amd64, and I have tried compiling grub with the
pentium3, and pentium4 CPUTYPE's in /etc/make.conf, to no avail.   Sadly, 
it seems as though vista has code in the MBR now, that seems to be part of
the bitlocker stuff.  FreeBSD's standard bootloader interferes with it,
causing Vista to give a error message about files being corrupted.
Maybe there is a "simple" (to the MBR guru types) that could be
implemented into the fbsd bootloader.
