I am having the same problem. On a Compaq 2100 laptop I can not get past the "I/O error" "very limited shell". I have used the cheat codes and nothing helps. I have put the CD in another computer and everything works great (except itsays my hard drive is not mounted but that is another issue for another place). I burned the CD at 8x (that is as low as I could). I even tried failsafe and I get the same result. Any other suggestions I have tried all of them on this post and the other post.
