Update:

OK, I discovered gpt. Here's the output:

# gpt show /dev/da0
        start        size  index  contents
            0           1         MBR
            1          62
           63  2929629402      1  MBR part 165
   2929629465  1464835815

Can anyone please give me some insight as to where to go from here?

Cheers,
Darren
