Yeah, r... is a raw device.

Looks like your BSD partition is slice 3. So your mount command
is going to look like:
mount /dev/wd0s3X /disk1
Problem is, we need a value for X here, to pick the BSD partition
within the slice. (ie a,b,c,d,.....) To list these partitons,
use "disklabel".
disklabel /dev/rwd0s3
Output will include at its end a description of the partitions:
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
a: 131072 0 4.2BSD 0 0 0 # (Cyl. 0 - 8*)
b: 262144 131072 swap # (Cyl. 8*- 24*)
c: 2088450 0 unused 0 0 # (Cyl. 0 - 129)
e: 144585 393216 4.2BSD 0 0 0 # (Cyl. 24*- 33)
f: 1204875 537801 4.2BSD 0 0 0 # (Cyl. 33*- 108)
g: 345774 1742676 4.2BSD 0 0 0 # (Cyl. 108*- 129*)
[root@castor /root]#
(from a disk of mine). so, to mount partitiion "e" of slice 3,
mount /dev/wd0s3e /disk1
To mount other partitions, maybe make other mount points, or mount on
a point brought in with a mount. (Confusing...) That disk just listed
is my "root" disk: a is the / partition, b is swap, c is "whole slice"
(not to be mounted), d is undefined, e is /var, f is /usr and g is /home
To mount that whole thing on a mount point, I would do:
mount /dev/wd0s3a /disk1
mount /dev/wd0s3e /disk1/var
mount /dev/wd0s3f /disk1/usr
mount /dev/wd0s3g /disk1/home
