I have an icon for the floppy and cdrom showing on the desktop after installing Knoppix to my hard drive. When I click on the cdrom I get "file:/mnt/cdrom does not exit and a similar message when I click on the floppy icon I get a similar message. My dual boot installation is on a IBM laptop. The floppy device is USB and the cdrom is actually a dvd/cdrom. What do I need to do to access these? Where can I find real basic "need to know" intructions for beginners like how to mount devices etc?
