One of them must, if you are getting this error.  Here's my machine.
Notice how partition 1 starts at offset 63 and I have / and other file
systems mounted on this slice (or on a disklabel in this slice).

% sudo boot0cfg -v da0
#   flag     start chs   type       end chs       offset         size
1   0x80      0:  1: 1   0xa5    365:254:63           63     71681967

version=1.0  drive=0x80  mask=0xf  ticks=182
options=nopacket,update,nosetdrv
default_selection=F1 (Slice 1)
% sudo boot0cfg -B da0
% sudo fdisk -s da0
