Abstract: The present invention provides a computer system for operation with a plurality of optional system consoles. A first non-volatile memory means stores present system configuration data. The present system configuration data is representative of the type of system console connected to the system. A diagnostic module accesses this configuration data for determining the operational validity of the system based upon a predetermined system configuration. The diagnostic module compares the present configuration data to the predetermined configuration. Based upon the comparison the diagnostic module modifies the operation of the system to communicate with the type of sytem console connected to the system.

Abstract: A personal computer system according to the present invention comprises a system processor, a random access memory, a read only memory, and at least one direct access storage device. A direct access storage device controller coupled between the system processor and direct access storage device includes a protection mechanism for protecting a region of the storage device. The protected region of the storage device includes a master boot record, a BIOS image and a system reference diskette image. The BIOS image includes a section known as Power on Self Test (POST). POST is used to test and initialise a system. Upon detecting any configuration error, system utilities from the system reference diskette image, such as set configuration programs, diagnostic programs and utility programs can be automatically activated from the direct access storage device.

Abstract: 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, an 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 clearing any stored privileged access password from 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.
