Keywords: DOS hard disk copy protection

Back about 6 months ago, someone from the University of Texas mention
a program that would protect a Hard Disk at boot-up time.  It also 
controlled the smart user with their own Dos disk which could be placed
in drive A:.    This program "PC-LOK10.ARC" was said to require a password
for access to the Hard Disk,  Otherwise any disk access to the Hard Disk
(C:) would return the standard message "Invalid Drive Specification".
Once entry of the password was given the drive would now be accessable.

Could this person, possible post this program to the net if it's PD.
I would be very interested in any other info about this program.
