What option argument did you specify for the -V (volume ID) option when
you created the ISO with the `mkisofs` command? I believe that the root
filesystem lies under /dev/iso9660/<volumeID> for which the ISO loader's
default configuration specifies as /dev/iso9660/FREEBSD_INSTALL. Thus
you'll need to change the vfs.root.mountfrom loader variable to be
cd9660:/dev/iso9660/<volumeID>

The host system is a fairly new 64-bit Macintosh which
is using VirtualBox. Here is the script to define the new
machine.
