That may be because the filesystem is not marked as clean. Try using fsck
to verify it's consistency. If that works, you should be able to mount it.

If you're using slices (which it looks like you are from the dev name
above) you should do bsdlabel /dev/ad0s1 to see the partitions in that slice.
Output from bsdlabel will look something like this assuming you used the
defailts when you installed:
test54# bsdlabel /dev/ad0s1
# size offset fstype [fsize bsize bps/cpg]
a: 524288 0 4.2BSD 2048 16384 32776
b: 2042752 524288 swap
c: 390716802 0 unused 0 0 # "raw" part,
d: 524288 2567040 4.2BSD 2048 16384 32776
e: 524288 3091328 4.2BSD 2048 16384 32776
f: 387101186 3615616 4.2BSD 2048 16384 28552
a should be your root partition.
d would be /var.
e is /tmp.
and f would be /usr.
assuming you used the defaults.

That warning is always there. It's just a reminder that sectors are
numbered 1-63 not 0-62.

Most BIOS will auto detect the hard drive just fine. If you stick with the
defaults you should be fine.
