I tried that on 4.0 and all it shows is my 1st partition. The second
partition is a 13GB FreeBSD slice and I can see the partitions in my
slice The third partition is a 5GB DOS Extended partition and it would
not show that partition.

The real problem is the identification of the partitions. I had
created a /dev/ad0s6, which mounted just fine using mount_msdos
/dev/ad0s6 /mnt. I hadn't done a MAKEDEV on ad0s5 and couldn't mount
it. Micke got me to thinking and when I looked in /dev it wasn't
there. After I did a ./MAKEDEV ad0s5, I could also mount it using
mount_ntfs /dev/ad0s5 /mnt.

I have always found it easy to remember because we can have 4 primary
partitions. One of those can be an extended with numerous logicals.
The logicals always start at 5 (no. of primary + 1). I was trying to
install Linux on a machine and had problems. I will probably try it
again now that I understand the arrangements a little bit better.

I have my extended partition after my FreeBSD slice on one system and
in front of it on the other system. The only problem on the one system
was getting / under the cylinder 1024 rule.
