dual boot install of freebsd windows xp using windows boot manager (early 2006):

install freebsd
set slices (aka windows partitions), leave first for fat32 10GB (type 12)
I set 2nd for ntfs partition (type 15)
slice/partition/format rest...
choose NONE/NO BOOTLOADER (do not touch bootrecord!)
after install of bsd reboot with windows install media
windows (xp) install now...
select to install on c drive (which dumps you into format of this slice/partition)
format with fat
as soon as format is done (it has a %complete gui) force a reboot
on reboot restart install process, selected my ntfs/unpartitioned-but-designated space
format and install....
after install boot into bsd from CD (I used freesbie)!
for the following I needed details provided by mount (freesbie automounts a bunch of stuff) the command "mount" alone will list the mounted filesystems, in the list you will see your first slice/C: drive (mine was ad0s1) and the mount point (mine was /mnt/dos.1 ):
mount the c drive read+write (as root) from the terminal, this (for me) was: mount -uw /mnt/dos.1
next I copied the desired boot file (I still am foggy on the details of mbr, etc etc) indicated in the freebsd install guide:
cp /mnt/ufs.3a/boot/boot1 /mnt/dos.1/BOOTSECT.BSD
and then edit my boot.ini file (vi /mnt/dos.1/boot.ini ) to add this boot option to the bottom:
C:\BOOTSECT.BSD

so my file looks something like (I only added the last line):
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows"
C:\BOOTSECT.BSD="FreeBSD"

rebooted

rebooted into windows and freebsd a few times to confirm it worked, and it does

additional topics/experiences:

power management in freebsd (as of 6, possibly earlier) is 
called ACPI for Advanced Configuration and Power Interface

portsnap is really great for getting the latest ports:
portsnap fetch
portsnap extract
portsupgrade -a (upgrade all my ports)
/usr/ports/sysutils/fusefs-ntfs has ntfs read and write support
portaudit -Fda ( ports/security/portaudit ) gets you security notices on all your ports, wow this is too easy
