I usually start with AsimCDFS as well, but here are a couple of things that may help out.
1) Once you get the OS installed with all your drivers, make an LHA/LZX archive of it. That way you can just unarchive it onto a clean partition to get a new start without a bunch of applications installed and without having to re-install the O.S., hardware drivers, etc.
2) Keep a spare partition on your hard drive to use for #1 above, and very handy for a number of re-install routines.
