Abstract
A storage device that supports Trusted Computer Group (TCG) security allows management of TCG security features by a Basic Input/Output System (BIOS) using non-TCG security commands supported by the BIOS. In one implementation, a BIOS that does not support TCG security but does support ATA security can use ATA drive unlock to invoke TCG drive unlock on the storage device. Further, the storage device can be transitioned among multiple security operating modes (e.g., Undeclared, ATA security or TCG security).
