Most BIOS also have a way to prevent you from changing the boot device without a password. (Locks you out from booting off the CD.) Now of this stops you from pulling the hard disk and using another system to change the root password. Most laptop hard drives will let you password the drive. The password function is part of the drive, so putting it in another machine does not help. If you really want to keep it safe, you encrypt the drive. This should stop most attempts to change the password. :-) Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
