XP recognizes FAT32 without any problem. I would upgrade to 5.1.1. Beryl is worth it. Whoever I have shown my laptop to wants it. The DVD image is greater then 4 gigs, so you can only save it to an NTFS partition.

As for usability, 5.0.1 is also quite good. It does not have the ntfs writing utility, but can write to fat32 partitions very well.

If you are buying a nic, check for compatible versions. I use the built in wireless nic on mine and it works perfectly.

Once you open your drive, just select root window from knoppix menu for root access or to change password.
