The monitor on this machine contains a simple boot program that
does not know about unix file systems. Therefore booting unix is
a 2 step process: The monitor boots the "real" boot program, and
this in turn finds the unix executable in the root file system and
starts it up.
The monitor can get the real boot either from a floppy diskette, or
from the disk header. The latter choice is obviously more convenient,
and in this step we'll make it possible by writing some version of
the real boot in the disk header at sector 30.
