Abstract
A computer system comprises a host computer having a memory array and a host microprocessor, and a disk drive having a drive microprocessor. The disk drive provides a secure boot load of the host computer by causing the host microprocessor to remain in an inactive state while a template for loading host computer memory is read by a drive microprocessor from a protected area of the disk and loaded into host memory via the host interface. The host computer may then be activated with a memory image source whose source is impervious to virus attack or inadvertent corruption. A method is disclosed for creating and updating the secure template. The host interface may be an I/O interface or a memory referenced interface.
