Yep, that's it. Been a long time with too much other crap in between.

My way was just reinstall the OS. OK, so I didn't know much then. :) (then?)

I wouldn't know enough to say if a kernel is crap or not. For what little I did with it, it was fine for me. The only thing I regretted was that I never got it on line. My ISP of that time was text-based although the 1200 baud modem would be a little slow. :)
