DFBSD + Grub ?

[Novice]

Hi,

I've just installed dflybsd with the new installer. When it asked me to
install a bootloader, I answered no because I have grub installed.
But I can't boot my dflybsd with grub.

My config:

1st disk:
  1st partition: OpenBSD 3.5
  2nd partition: Linux ext3
  3rd partition: Linux swap
2nd disk:
  1st partition: DflyBSD
  2nd partition: extended with fat32 inside

I try to configure grub like for a freebsd boot:

title  DragonFlyBSD
root   (hd1,0,a)
kernel /boot/loader

But it seems that dragonfly use a different kind of slice than freebsd.
grub doesn't recognisez it:

grub> root (hd1, <tab>
 Possible partitions are:
   Partition num: 0,  Filesystem type unknown, partition type 0xb
   Partition num: 4,  Filesystem type is fat, partition type 0xb

So I try to configure it to boot like a windows system:

title DragonFlyBSD
rootnoverify (hd0,0)
makeactive
chainloader  +1

But when I try to boot, grub say me "boot error".

Is it possible to boot DFBSD from grub ? Does lilo can ?

Thanks to help me
