Enabling TPM on HP Zbook and Elitebook laptops

Ran into an issue this Am with trying to enable TPM or Trusted Platform Module on a new Zbook from HP.  If you hit ESC then BIOS Options, then Security you will see that TPM, User Management and a few other options are greyed out.  Turns out you must set a BIOS Password in order to change those options.

Stupid move HP but whatever I guess, at least now I can encrypt the drive.
