Hello , I would like to try Debian on My Toshiba nb205 which is a stock notebook from best buy. So hear are few questions I have. 1. is it fully capatible with this unit? 2. what type of anti virus softwear is good for debian? 3. Dose it come with Anti virus ? 4. how much space do i need on a memory stick to download the debian os using another pc so i can load it to the tosiba? Thank you Heath
