Default Boot freeBSD from USB drive?

Thanks to Carpetsmoker for telling me about this great place.
To begin my apologies if this is not meant to be in here. I was unsure where this would fit.

What I am trying to do is dual boot my computer with freeBSD and Windows. I want the Windows boot loader to be there for it all to work as standard and only to boot into freeBSD when my usbkey is in the computer. I can do the partitioning and all that however I am stumbling at this bit of getting it to boot freeBSD from a usb-key, I don't want my filesystem on the usb key I only want it to boot from a USB key. I have looked into boot0config but donot see how I can do it.
I tried the following after copying /boot /mnt/usb(/dev/da0):
fdisk -B -b /boot/boot0 /dev/da0

I also tried this:

mount /dev/da0s1 /mnt/usb
mkdir /mnt/usb/boot
cd /boot
cp -Rpv * /mnt/usb/boot
boot0cfg -B -s 1 -t -v 182 /dev/da0

So now when I select FreeBSD when I boot by usb I get some BTX Error and the screen scrolls so fast that I cannot make out what is being meant however it does look like numbers. Any ideas?

I would be really grateful if anyone can guide me in this.

Thanks allot.
