I certainly appreciate the good advice, but I could
use a little more information.  

I'm not really worried about saving the system and the
MBR, just my /usr/home directory.  Can I install the
system again (from floppies) without the inode chain
getting messed up and the /usr/home directory becoming
invisible?  I would like to know if I can just
reinstall over the original installation much like a
Windows fix; the inode error that I'm getting now
prevents /bin/sh from loading and may have made the
system unsalvageable.
