booting DragonflyBSD Unix?

[dchmelik]

I installed DragonFlyBSD Unix (people were saying has more efficient/fast SMP than FreeBSD Unix) and tried to configure GRUB2 (from Slackware64 15+-current GNU/Linux) to boot it, but can't get it to boot any way, even from it's installer.
        This is in /etc/grub/d/40_custom.

menuentry "DragonFlyBSD Unix" --class dragonflybsd --class bsd --class os {
  set root=(hd0,msdos3)
  kfreebsd /boot/loader
}

        A similar menu currently works for both NetBSD Unix & FreeBSD. I also tried 'kfreebsd /kernel/kernel' in there.
        That won't boot, and DragonFlyBSD's own boot-loader (on installer) won't either: apparently isn't fully-documented (I dropped to command line, tried 'lsdev' (found correct slice,) 'set currdev=disk4s3a,' 'boot /kernel/kernel.')
