Yes and no. Most of the compiling will be much smaller than a kernel, not even complete packages. I think I said it but you've clipped that part, but this is a course in programming that includes writing some drivers. Emulating the superH processor is going to be a bit demanding, particularly if I find myself wanting to compile a superH kernel and not having access to the school labs over a long holiday. I am aware of that and will plan accordingly. Mostly, I was trying to dig up the AMD-V support and something in the thread pointed me the right direction. I'm not planning getting more than AMD-V in a portable machine. Don't want to carry a boat battery with me. :-p -- Joel Rees Be careful where you see conspiracy.
