The default root password on netwinders is 'vnc' (without the ' quotes).
If you want to change it, try to start linux with the following command
This will drop you in a very bare system with a root shell. Now mount the
root filesystem read-write, make a backup of the password file and edit
mount -n -oremount,rw /
cp /etc/passwd /etc/passwd-backup
Edit the root account in such a way that the password entry is empty, like:
Save the file and exit vi. Sync the disk caches and mount the filesystem
sync ; sync ; sync ; mount -n -oremount,ro /
Reboot the machine by using Ctrl-Alt-Del. The machine should come up in
the normal way and you should be able to log in as root without password
(immediately set a new password).
If you happen to use shadow passwords, also backup /etc/shadow, remove
root from /etc/shadow and edit /etc/passwd like I described above.
Hope this helps,
