Hi, Quing Feng,

at http://www.ba-stuttgart.de/~helbig/os/v6/pdp11 you'll find a detailed 
description of the pdp-11 and its peripherals as needed for understanding design 
and implementation of V6.

and at http://www.ba-stuttgart.de/~helbig/os/script/chapt2.4 you'll find a
description of the init process.

have fun,
Wolfgang Helbig
