Hey welcome to my life
I have no idea how to get passed it, it's kinda annoying.
I'm not sure, but I have a feeling a floppy disk can only be used a limited number of times.
So I just reboot my box only when I absolutely *have* to
By the way I'm using Slackware 9.1 and am encountering the exact same problem you speak of, however, as far as I know, I actually did install LILO :x
