Removing pre-boot password in DellControl Point Security Manager for Latitude E6400

I wanted to try the biometric scanner as a method of logging on, and had to add a system password to do so. Since i've decided not to use the fingerprint scanner, and removed it, but the password is still required to boot the computer. I can't find anyway to delete it and google hasn't helped. Anyone know how to remove a preboot system password (or at least disable requiring it) ?
