Use dd's of= parameter to send output to a file. If it really has to be
an ISO, pipe it to mkisofs. Using dd like that makes big files with
lots of wasted space. The article I posted earlier shows how to save
some of that by filling the disk's empty space with zeros. Then gzip
can do some useful compression.

A hybrid approach would be to save the first 63 blocks with dd, then use
dump for the UFS filesystems.
dd if=/dev/ad0 of=mbr.bin count=63
