I have an old laptop that I thought I'd try DSL on. I followed this guide: http://www.damnsmalllinux.org/wiki/loadlin_install.html.
First I put a fresh copy of Dos 6.22 on the 512mb drive. On the base of the drive I have the two folders C:\isolinux and C:\knoppix.
It starts up but ends with the limited file system:
Accessing DSL image at /dev/hda1.../modules/cloop.o: init_module:
Can't find KNOPPIX filesystem, sorry.
Dropping you to a (very limited) shell.
Again, on c:\knoppix is one file knoppix. What could I have done wrong?
