    摘要： An apparatus for loading BIOS stored on a direct access storage device in a personal computer system, the system comprising direct access storage device, and a processor card removably mounted to a planar board. The processor card comprises a system processor and ROM memory, while the planar board includes a main memory. A master boot record is stored on the direct access storage device. The master boot record contains a data segment and an executable code segment, the data segment representing the hardware configuration of the personal computer system. A first portion of BIOS included in the ROM memory initializes the system and causes loading of the master boot record into main memory. This first portion of BIOS further compares the hardware configuration data of the master boot record with the hardware configuration data in the ROM memory to verify compatibility with the system processor. Once compatibility of the master boot record with the system processor is verified, the first portion of BIOS transfers control to an executable code segment of the master boot record to effect loading of the remaining portion of BIOS into main memory, and the first portion of BIOS is discarded.

    摘要： This invention relates to personal computer systems and, more particularly, to such a system having security features enabling control over access to data retained in such a system. This invention contemplates protecting a personal computer system which has the capability of becoming a secure system from being placed into that condition by an attack on an unsecured machine. Additionally, in a network environment, it is important to maintaining network security that any given particular system be uniquely identified to the network, in order to guard against the substitution of an insecure "alternate" which would open the network to attack through an insecure system. This invention contemplates provision for such identification in a secure manner.

    摘要： This invention relates to personal computer systems and, more particularly, to such a system having security features enabling control over access to data retained in such a system. In particular, a personal computer system in accordance with this invention has a normally closed enclosure, at least one erasable memory element for selective activation to active and inactive states and for receiving and storing a privileged access password when in the active state, an option switch operatively connected with the erasable memory element for setting the erasable memory element to the active and inactive states, a tamper detection switch operatively connected with the erasable memory element for detecting opening of the enclosure and for invalidating any privileged access password stored in the erasable memory element in response to any switching of the tamper switch, and a system processor operatively connected with the erasable memory element for controlling access to at least certain levels of data stored within the system by distinguishing between the active and inactive states of the memory element and between entry and non-entry of any stored privileged access password. In the presently preferred form of the invention, two non-volatile erasable memory elements are provided, one an EEPROM and the other battery backed CMOS RAM.

    摘要： This invention relates to personal computer systems and, more particularly, to such a system having security features enabling control over access to data retained in such a system. The features here described include a prioritized initial loading program for enabling initial loading of an operating system from a selected one of a plurality of sources, the prioritized initial loading program normally designating an interpreter program as a final option default in the event of failure of access to an operating system from any other one of the plurality of sources; a security utility program for enabling a designated user to (a) selectively modify the initial loading program by specifying the number and priority order of the plurality of sources and (b) selectively modify the initial loading program by deleting the interpreter program from the plurality of sources; a master cryptographic key for use in encrypting and decrypting data processed by the system CPU; and a second security utility program for enabling a designated user to modify the master cryptographic key.
