So "fdisk -B ad3" shouldn't work if you don't have a valid partition
table which also has the correct fdisk partition marked "active" (or
"bootable", which I'm fairly sure is the same thing, despite what the
fdisk manual implies).
But is seem that "fdisk -I ad3" should work if you have a "s1"
correctly configured and populated. But after using it, I'd
run "fdisk ad3" and verify that your "s1" is marked "(active)".
It sound like /boot/mbr behaves like an IBM/MSFT MBR, while
/boot/boot0 is the standard FreeBSD MBR configured by "boot0cfg".
