Is there a way of booting to single user? 
Then you'd have root rights.
Does it boot automatically?
Do you have other disks with the os were you have root access?
Then you could mount the disk and edit files.
You could always put the disk in another machine that could read the 
CLIX filesystem (what filesystem is used?).
