Maybe it helps if you read section "System Initialization" in teh

I don't know where you initialize the RAM.

Well, what seems unnecessary to you is actually pretty important to

I realize that command does have its fascination, even under  circum-
stances such as these, but I neither enjoy the idea of command nor am
I  frightened  of  it. It simply exists, and I will do whatever logi-
cally needs to be done.
