Installing Slackware from scratch via Debian already installed ...

Hi, I am about to try a slackware installation in a http/postfix server that is running under Debian and I cant boot any kind of media couse there is no cdrom and no floppy drives that I could use. So I was thinking about installing the slackware manually under the debian install. I was reading in the web about this kind of installation and the farther I've got was the idea of creating a tmp directory and installing the basic stuff to a slackware bootstraping. The problem is that I cant fail, I've got to do this at once :shock: , so I want to be really sure of exactly what to do, so any hints and help are welcome. :D If my question is stupid, don't be afraid of telling me :wink: thaks for your attention :)
