Never used it myself but from the PDF

Consumers can easily integrate this drive and use their BIOS
password to set up authentication. They get easy, strong encryption
with no performance impact.


So it sounds like your prompted for the password when you boot
the system, probably during POST somehow. Maybe it only works on
special modern versions of BIOSs.
