Management of Full Disk Encryption (FDE) drives is usually handled in BIOS or via central Windows application.
I also expected unlocking at boot to be handled by the BIOS/UEFI, but according to http://www.trustedcomputinggroup.org/resources/commonly_asked_questions_and_... it is actually the drive that boots a mini OS/pre boot loader that asks the user for the password and passes the actual MBR back to the BIOS after the drive gets unlocked. Nifty.
