Well, sort of OK. I would not be inclined to put a FreeBSD slice
right in the middle of your MS logical drives. But, I think you
could do it.
Secondly, I don't know what just having 500 MB for a FreeBSD '/' would
get you. It would not be enough to run FreeBSD. But, probably you
haven't told the whole story. Something else must be there. Anyway,
I would be inclined to take the FreeBSD slice out of that empty GB
space that currently shows up as g: on you Microsloth system.

I have successfully used Partition Magic for this sort of thing.
It is available at not too high a price from most places that
sell software. As long as all the MS stuff is FAT, I think
there are some free tools that will work too, but I haven't used
them so can not attest to their effectiveness or reliability.
A couple come with the FreeBSD distribution. But, the free tools
do not handle NTFS which is why I haven't used them.
You will first need to use the disk tool such as Partition Magic
to shrink the existing structures and put a new primary slice in
the space.
Then, when you run the FreeBSD install, you have it mark the slice as
a FreeBSD slice. Up until that point, it is not really a FreeBSD ad0s2,
just some generic space. Partition Magic does not know how to mark
the slice (which it calls a primary partition, using MS terminology)
as a FreeBSD slice. So FreeBSD's fdisk does it. (Even if you
use sysinstall to write the slice, it really just calls fdisk)
Good luck,
