Dir : boot

                              The Boot system

The files in this directory work in conjunction with a switch box
that either put in communication :
	1) vax - terminal
	2) lsi - terminal
	3) vax - lsi, echo of the lsi on the terminal

The code in boot.s is patched in high memory via odt commands issued by the
sequence  of echos in boot.  Then the bootstrap is run and fills the memory
reading bytes through the serial line.  If chks ok, starts the  program  at
'2000'.  If  the  code  in  boot.s  is changed, mkboot generates a new boot
file.  The program mkabo is a utility program that use  a  symbol  stripped
a.out  file from the ld11 loader and make it down loadable.  The shell file
'dl' schedules  the  downloading  procedure.  If  the  code  in  the  lsi11
crashes, restart by odt : '2000G'.

Things in old directory work with a lsi11/03 and not a lsi11/23
