I recently purchased this motherboard and have updated it to the latest 0070 BIOS. I purchased a 120GB Intel 520 SSD at the time as well, and paired it with a brand new ivy bridge i5-3570K. Currently using the onboard graphics temporarily, as well as 2x4GB sticks Corsair Vengence DDRIII-1600. As I valued reliability and security over the best possible peformance for my money, I felt it approperiate to spend the extra money to get my main components made by a single vendor with a better track record for reliability and lack of problems than the competition
Once I placed an encrypted drive in the computer, I was not able to unlock it if I needed to press the shift key while typing in my password at the "Enter Hard Disk Drive Password. I have uploaded a vi deo below. Any time when I press shift, my computer emits a loud beep and I have tried multiple keyboards.
My computer with the DZ77BH-55K is saying it requires a password to use the drive, even if I have a blank password set. Even if I have a password with all lowercase characters, the computer will still not unlock the drive. My Intel 520 series SSD is an expensive paperweight if I want to use it with my DZ77BH-55K.
My SSD works fine on other PC's that are many many years older that have been able to correctly implement the ATA security extensions which have just existed for 20 years or so...
