I got it!
I have just used grub instead of lilo and I forgot to include initrd on the knoppix line of menu.lst.
Sorry for this post!
I get this message whenever I boot my ver 3.3 installation:EXT2-fs warning (device ide0(3,6)): ext2_read_super: mounting ext3 filesystem
as ext2
VFS: Mounted root (ext2 filesystem) readonly.
I am not sure if this was the case for previous versions but I just noticed this now.
What is wrong here?
