摘要:
Systems, methods, and machine-readable media for storing a recovery image on a secondary memory device on a computing system and updating the recovery image. In some aspects, the system may include a main storage device comprising an operating system, a secondary storage device, internal to the computer system and separate from the main storage device, comprising a recovery image, and a processor configured to determine whether to boot the computer system in a normal mode using the main storage device or in a recovery mode using the recovery image on the secondary storage device. In some aspects, the system may also include a recovery circuit configured to prevent access to the secondary storage device during the normal mode when the recovery circuit is disabled and to permit access to the second storage device when the recovery circuit is enabled during the recovery mode process.
