First, welcome to FreeBSD.  

It sounds like you didn't allocate a swap partition during the
installation when you were asked to allocate partitions on ad0s1.   If
you don't take the defaults, then you must allocate swap space
explicitly.  This should be done on partition b, i.e. on ad0s1b.

I suggest you do your first install taking all of the defaults.  If you
choose a "minimal installation" it will go very quickly.  After you get
one installation variant of FreeBSD running, you can experiment with
alternate variants of the partitioning of ad0s1.  Check each
installation with

#disklabel ad0s1

Each variant will require a swap partition.  

The Handbook and FAQs are excellent and should be your primary
references for awhile. There is a link to each on Don't
be afraid to click the Newbies button; it will lead you to many fine web
sites with tutorials.  A couple days ago someone recommended which looked good enough to me to bookmark.
If you have a lot of Linux experience, it is a good site.

Best of luck,
