right people, i have just scraped 3 free computers and keyboard etc from the school my dad works in, (they were being chucked out) now i know nothing about these computers, i think they are running xp, havent looked at any of them yet i dont know if they work! all i am going to be doing is wiping them and installing linux onto them, which i have never used before. i understand that its command line?anyway, can i run linux as well as xp? or will it have to be a clean install? what equipment will i need? i have a switch and enough ethernet cables to choke an elephant, what else will i need? i wanted a router but atm i am scrounging!
