Can you say something about how the self-encrypted system appears to users? When do they enter the password? What software asks for the password? Is it an alternate boot loader? You mention that any standard PC hardware should work, but sometimes I have seen it said that the BIOS must support encryption - is that false or an alternative arrangement? How is the password established? Is there a Windows program that one runs to turn on encryption and establish the key? Is there a similar Linux program? Can a drive move from Windows to Linux without losing the data?
