Sorry for delay.....
Can you boot into your distro at all? If so, try in a console
If not grab a live cd - and access your hard drive that way.
is it possible to backup your data to cd or another partition? if you have a spare partition you should copy it like so
Code:
cp -a /usr/* /path/to/spare/partition/
if so then it may be worth formatting to ext3.
For easy access to manual pages try this in konqueror
Simply type a # followed by the command you are interested in. Each to their own, but I would recommend upgrading to either ext3 or reiserfs. There are a few options to follow up. let me know if you need more specific info and I will see what I can do :-)
