Danke. This worked fine.

And all was good. I can use my the DragonFly install. My only problem is 
when I reboot I have to that each time with the boot CD.

Now to figure out how to get a boot manager on there. I used:

  boot0cfg ad0

and it said:

  boot0cfg: /dev/ad0: unknown or incompatible boot code

I then did:

# disklabel -B ad0
super block size 0

Maybe should have used ad0s4 as the man pages warned? I rebooted and no 
change. My previous boot menu was still there. And choosing my DragonFly 
just reboots instantly.

I did it again with "disklabel -B ad0s4". And still no change.

Any suggestions on creating a boot manager using tools provided with 
DragonFly? I need to boot: NetBSD from slice 1, FreeBSD from slice 3 and 
DragonFly from slice 4.

I do have a boot loader now that works for NetBSD and FreeBSD and has a 
non-working entry for DragonFly.

Later I may try Grub for this as someone else suggested to me. I may also 
try doing this from the NetBSD install.
