Abstract:
Systems, methods and products are described that provide secure boot with a minimum number of re-boots. One aspect provides a method including receiving an indication to boot from a power off state at a computing device; responsive to authenticating a user at one or more input devices, releasing a value derived from authenticating the user at the one or more input devices; responsive to releasing the value, unlocking one or more encrypted drives with a previously established alternate credential; and thereafter proceeding to boot from the power off state. By not having to call the non-BIOS software each boot, this minimizes the number of reboots for each boot cycle.
