Okay. I thought I had tried that, but now I see I used that switch with
fdisk and disklabel but used different options with boot0cfg. (Without the
-B I was getting "unknown or incompatible boot code" each time.)
That did give me a boot menu, with:
F2 has no operating system. And F1 boots NetBSD and F3 boots FreeBSD fine
But F4 just beeps (like when pressing invalid F5).
So I booted with the LiveCD again, created the ad0s4a device node, and
disklabel -B /dev/ad0s4a
Rebooting still didn't fix the F4.
Can someone please summarize the disklabel, fdisk and boot0cfg options
(maybe with some examples) specifically for making a system bootable and
also for a multi-boot menu?
And is there a certain order these things are supposed to be done in?
Once I get this figured out, I will make sure this is clearly documented
in the online DragonFly book.

system already had NetBSD and FreeBSD. I chose not to install the boot
manager in the DragonFly installer since I didn't want to lose access to
easily booting to the other systems. I was hoping that the boot menu would
