I was looking for information of which file generated by compiling
the code under /usr/src/sys/boot/i386 represented the boot blocks. The
instructions I found on the web page said to use one of the files generated
from compiling the source in /usr/src/sys/i386/boot/biosboot. Specifically
using the file called boot.nohdr, the 2.2.x boot blocks. Your method,
however, would work just as well.
Although I was hoping for something using the cp command instead of
the dd command, for novice users. cp seems to have less potential for
damage than dd.
Thanks again. I'll use your method and continue investigating.

I'm not 100% sure what you're after here, but if you simply want
to get FreeBSD booting off the NT boot menu again then just repeat
what you did with 2.2 (assuming drive C: is mounted on /mnt).
``dd if=/dev/<raw_fbsd_slice> of=/mnt/BOOTSECT.BSD bs=512 count=1''
You may have to boot FreeBSD from a floppy or the CD and select
the Fixit option.
I found I had to recreate C:\BOOTSECT.BSD after u/g 2.2.8->3.1.
