Rui,

I have finished testing and concluded that the offsets must be on
cylinder boundaries and creating a small partition for the storage of
ofwboot and the boot block is required.  Note the following:

# disklabel -r sd0 | tail -6
5 partitions:
#        size    offset     fstype [fsize bsize cpg/sgs]
 a:  35373821      4712       RAID                    # (Cyl.      1 -   7508*)
 b:   1046064  34326920       swap                    # (Cyl.   7285 -   7506)
 c:  35378533         0     unused      0     0       # (Cyl.      0 -   7508*)
 e:      4712         0     4.2BSD   1024  8192   592 # (Cyl.      0 -      0)


# disklabel -r sd1 | tail -6
5 partitions:
#        size    offset     fstype [fsize bsize cpg/sgs]
 a:  35373821      4712       RAID                    # (Cyl.      1 -   7508*)
 b:   1046064  34326920       swap                    # (Cyl.   7285 -   7506)
 c:  35378533         0     unused      0     0       # (Cyl.      0 -   7508*)
 e:      4712         0     4.2BSD   1024  8192   592 # (Cyl.      0 -      0)


The URL I mentioned earlier was instrumental in getting this to work.
Booting now works correctly from either disk.  Would you like me to
attempt to modify the XML file again to include these details?
