Hopeless.  You'll at least need a /boot UFS partition.  Also you'll 
probably have to modify grub to read DragonFly disklabels (although I 
have a setup here booting with grub, so I don't know how I managed that 
:).  Oh yes, you'd need a disklabel32, not a disklabel64 to have the 
slightest chance of making grub work.


Or try a /boot in ext2, then also grub should be able to read it :D

Alternatively you could try using a chainloader in grub.

Grub boot-loading HAMMER

[rektide]

Hello,

I'm trying to use Grub to dual boot into DragonflyBSD running on a
HAMMER slice.  The install wouldnt let me install boot blocks onto
ad0s3 where my HAMMER lives, so I logged in as root from the LiveCD
and boot0cfg -B ad0s3'd: I'm not sure if this was necessary or
advisable.  I'm also not sure if this utility is what the installer
would have used to install boot blocks, or whether Dragonfly has a
different utility.  The installer also didnt change the FS type of the
partition: its still listed as FAT16, even though it was formatted
over.

After these install procedures, I tried using grub to load the slice.
I tried chainloader'ing it, as well as specifying a kernel
/boot/loader.  The first gave me an Error 13: invalid or unsupported
execution format and the second an Error 17: unable to mount
partition error.

I'll be on IRC.  Ping rektide.  Or respond here.  Thank you for your time.
