Don't miss HOWTO: Upgrade the Poor Man's Dual Boot
http://www.knoppix.net/forum/viewtopic.php?p=12040

I strongly recommend using the faster DOSbootdisk with the Poor Man's Dual Boot. I have reinstalled all my PCs (100 on a LAN, 5 others off the LAN but on cable modems) this way, works great!

Enjoy!
