Other Help Topics :: Getting CD to boot via floppy?
try booting "dsl failsafe"
just don't do a HD install untill you work out your probelms.
Try this:
Copy the contents of your CDROM (IE: the \KNOPPIX folder) to your C:\ drive so that you have "C:\knoppix" and the files.
Then use the boot floppy. It will detect your DOS/Win95/98/ME partition as if it were a CDROM drive.
