Edwin,
Boot the server single user, -s. Then if you need to, bring up the IP
stack manually. Depending on your mount points, booting single user only
mounts root, so you can try to fsck the other unmounted filesystems. Only
if those file systems are readable will you be able to get your files off.
You can also try tar'ing files to floppy or other removeable drive you may
have on the server. Not a great solution, but it may be all you can do.
-Derek
