Abstract
A computer system is disclosed. The computer system includes a storage device, a device controller and a chipset. The device controller includes lock registers having values that correspond to the ranges of locked sectors of the storage device. The lock registers verify if a storage device access request is targeted for ranges of sectors of the storage device that are locked. The chipset includes an embedded controller to authenticate the storage device access request and to manage configuration of the storage device.
