I have tried Knoppix and I like it but I have a few problems that I have not been able to fix so I am wondering what other Live CD would people recommand that I try?

The problems with Knoppix that I have is that it does not detect my parrallel and serial ports, which makes me not able to get my printer to work, and the other is my modem is detected but I can not use it.

What Live CD would you recommand in order to get these two issues to work? Thanks.

EDIT:
Also what Live CD would be able to open MAC floppy disk?
