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
