Hi,
Just a point of clarification here before it causes more confusion.

Here there seems to be some confusion on the use of the word partition.
FreeBSD uses the term "slice" to mean the major division of the disk
that Microsloth uses the term "partition" for. You need only two of
these slices (MS partitions) - one for Windows and one for FreeBSD
although you can have as many as 4. Those slices are identified in
FreeBSD land as s1..s4 (ad0s1..ad0s4 for IDE disk one for example) and
as a letter drive in the MS netherworld (typically drive c, d, etc)
These major divisions called slices are created by fdisk.
Then, you further divide the FreeBSD slice in to partitions using disklabel
which are named a..h. FreeBSD calls these sub divisions 'partitions'.
You create filesystems on these FreeBSD partitions and mount them.
There are conventions and expectations for some of these. Usually 'a' is
used for the root (/) file system, 'b' is used for swap, 'c' us unused
and set up to refer to the whole slice by a few things, 'd' seems to be
unused, but I don't know the reason. The remainder (e-h) have any use
although often 'e' is used for /tmp 'f' is often used for /usr or /var
or sometimes /home depending on how you choose to spread out and manage
your disk space.
Often second and and subsequent extra disks are assigned to one whole
use and in that case it is common to use either 'a' or 'e' or 'f' to
be its name. Some times a chunk of each extra disk is used to add to
swap space and typically the name 'b' is used for each of those regardless
of which other letter names are used for the rest of the disk.
So, for example, if you have a machine with 3 IDE disks, split the first
to be boot disks for MSwin and FreeBSD, dedicate the second to MSwin and
use the third to add to swap and work space, you might have disks addressed
as follows: (Size choices are up to you, but remember, you always want more)
ad0s2a mounted as / (eg root)
ad0s2b swap
ad0s2c a comment describing the whole ad0s2 slice
ad0s2e mounted as /tmp
ad0s2f mounted as /usr
ad0s2g mounted as /var
ad0s2h mounted as /home
ad2s1b swap
ad2s1f mounted as /work
ad1s1 cal also be msdos mounted as something if you like.
Note: You will need to install the boot loader on each disk that will have
bootable systems on it. In this example, that is only ad0. And you will
need to put a Master Boot Record on the first boot disk (from the BIOS point
of view) - ad0 in this example. If you choose to make all of the first
disk (ad0) be dedicated to MSwin and the second disk (ad1) dedicated to
FreeBSD, for example, you would need to write a boot loader on both ad0
and ad1 and the FreeBSD MBR on the first disk (ad0) even though you don't
put any other FreeBSD stuff on that disk. That is because the BIOS starts
with that first disk to figure out how to boot and then the MBR takes over
from there. And, at least up to WinXP the Microsloth MBRs could not boot
a UNIX OS - but FreeBSD could do either. I have heard tell that now the
MBR that comes with XP can do both, but haven't tried it.
Although the descriptions of fdisk and disklabel in the man pages can
at first be rather confusing, after a while they begin to make sense and
are relatively easy to use.
But, you can also use the sysinstall, either from an install CD or
by invoking /stand/sysinstall and it will also do all your calculations
for you in a minimal GUI interface. Sysinstall will also make it write
the boot loader and MBR if you want.
MS doesn't have anything exactly the same as those sub-partition divisions
of the slice (tho it does have something else vaguely similar called an
extended partition that is not compatible).
So, this was a bigger comment than I had planned, but we seem to go over
and over this same confusion so often.
Sorry for no Russion. I took it about 39 years ago, but remember
almost none.
