The bootfile is located via a LSN pointer in LNS0 on the hard disk. The boot
need only look there, and then seek to the designated spot, and read the
bootfile.
In coco land, os9p1, REL, Boot, and Init (?) are on track 34 of the boot
floppy, and are loaded by the DOS command (reads 18 sectors from track 34 into
memory). Once loaded, they jump into it, and it takes over by enabling the
appropriate RAM mode, copying the modules to high RAM, and then jumping into
os9. That's the 1st level boot. Then os9's Boot module takes over (via OS9p1)
and loads the OS9Boot file.
