dual boot winxp & 9.1-rc3

[Fbsd8]

On an old 20gb hard drive I first installed winxp on the first half of 
the HD. winxp booted fine. Then I installed 9.1-rc3 on the second half 
of the HD. Now when I boot the HD I only get 9.1-rc3. Winxp created mbr 
and installed winxp into first dos partition. 9.1-rc3 uses bsdinstall 
which uses gpart to create the slice as gpart show displays as see below...

=>      63  39862305  ada0  MBR  (19G)
         63  19928097     1  ntfs  (9.5G)
   19928160  19933137     2  freebsd  [active]  (9.5G)
   39861297      1071        - free -  (535k)

=>       0  19933137  ada0s2  BSD  (9.5G)
          0  18933760       1  freebsd-ufs  (9.0G)
   18933760    995328       2  freebsd-swap  (486M)
   19929088      4049          - free -  (2M)

Now I want to add BSD dual boot to the MBR.
Is this all I need?

  fdisk -B -b /boot/boot0 ada
