Well, GT compiling a kernel might be a breeze for a few of you more advanced users
but for newbies like me and delta5, it's not just that simple. I'd like to think that Mandy might make use of the SMP by default, as this would really hinder a single CPU system by enabling it right up front.
Since you are wanting to learn linux, I would like to suggest checkin out a tutorial over at www.linux.org
where they teach you some basic command line usage, some file structure, and few other odds and ends that help make linux, linux. It's worth your time, and will really help if you do end up requiring a kernel rebuild (which there are some good how-to's out there on, some great threads here on, and if you have any additional questions, lots of great experts here to help you as well).
