Unlocking CDROM

[gsam at trini0.org (Gerard Samuel)]

Im running
gladiator# uname -a
FreeBSD gladiator.trini0.org 5.0-RELEASE-p5 FreeBSD 5.0-RELEASE-p5 #0: 
Fri Mar 21 10:39:46 EST 2003     
gsam_(_at_)_gladiator_(_dot_)_trini0_(_dot_)_org:/usr/obj/usr/src/sys/GLADIATOR  i386

and I mounted an ata cdrom via mount, viewed the disk, got out of the 
/cdrom directory, and issued unmount /cdrom.
Via df, it is no longer mounted.
But Im unable to eject the CD from the front panel.  I remember that 
there was an eject command for scsi cdroms, but
not sure if they exist for ata cdroms.

What can be done to unlock the drive?
Thanks
