METHOD OF INSTALLING INITIAL BOOT IMAGE, METHOD OF UPDATING INITIAL BOOT IMAGE, AND STORAGE DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a new and improved method and system for managing an initial boot image in an information storage device. PSOLUTION: A storage device configured with a user-addressable LBA space stores an initial boot image in a region of the LBA space that is outside the user-addressable LBA space. Updates to the initial image are carried out as an un-encrypted process when speed is desired. A second copy of the initial boot image may be maintained by the storage device to provide for update flexibility. When two copies of the initial boot image are maintained, one is designated as active and the other is used for updates. When an update to a copy is completed, that copy is designated as being active (step 618). PCOPYRIGHT: (C)2010,JPO&INPIT
