Learning how as I go .... how do I break out of the boot loader, to 
what shell? What runs this series of instructions?
Thats is deeper than I have gone to this point. Like, even though I 
have found my way around the shell enough
to do tar -xvf (ect) and ./config and all those incantations, and even 
find my way through errors here and there,
tinker with some shell scripting, python scripting, even some console c 
programming; and lots and lots of php.
Nothing can be worse than javascript from scratch from text books. But 
I got the hang of that too.
this is something I am unfamiliar with.

just some extra data if it makes a difference here, I am using generic 
kernel, not AMD64 (and I presume
there is a difference).

Thanks for the response and info.
