<disk>
      <partition 1> FAT32, Active, 15Gb
      <partition 2> FreeBSD/i386, 36Gb
      <partition 3> no
      <partition 4> no
----
Problem with this boot-style exist on dell 1300, bios rev. A09, on my
ASUS P4 X-800 on FreeBSD 6.2 it's worked fine, but now i can't try 7.0
no space on disks. :(

that do:
#bsdlabel -B ad0s2
mount /dos
cp /boot/boot1 /dos/
( adding string to boot.ini )

!reboot
select from ntloader menu "FreeBSD"

FreeBSD/i386: Invalid Slice
Default: 0:ad(0,a)/boot/loader
