That's a shame since I liked runing mknbi-dos on a directory and it
making an image.  Also for some reason the floppy image I use
doesn't work with the Etherboot version but worked with the Netboot
image.  Also I would use Etherboot to load nbgrub to netboot
OpenBSD/NetBSD/Linux (and for Linux I could just boot the Linux
kernel directly without doing a mknbi on it).

Okay I got something to work.  I was confused the option mkelf-menu.
I had to add vendorext_is_valid=1 under FreeBSD since we use that for
swap path.  Doesn't look like there is any serial support and therefore
no dual console.  I tried to load FreeBSD via the menu and it died.

Hmm, now rebuilding Etherboot with -DRELOCATE caused VMware2 to
blow up changing the RELOCADDR address so it does conflict gets
me "Unable to load file" after it load the menu.  I'll try it on
real hardware again tomorrow.
