摘要： Described is a computer system which is coupled to a remote computer via a network cable. The computer system has a normally closed enclosure and is capable of securing data retained within the system against unauthorized access. The computer system includes an erasable memory element mounted within the enclosure for selective activation to active and inactive states and for receiving and storing a security password when in the active state. A manually operable option switch is mounted within the enclosure. The option switch is operatively connected with the erasable memory element and manually settable by a user of the computer system for setting the erasable memory element to the active and inactive states. A cable removal detector is coupled to the enclosure and is operatively connected with the erasable memory element for detecting a disconnection of the cable and for clearing any stored security password from the erasable memory element in response to any switching of the cable removal detector between a first state and a second state.

摘要： Access to secure data through a portable computing system is provided only when a timer within the system is running. The timer is reset with the portable system connected to a base system, either directly, as by a cable, or indirectly, as through a telephone network. In an initialization process, the portable and base systems exchange data, such as public cryptographic keys, which are later used to confirm that the portable system is connected to the same base system. In one embodiment, the initialization process also includes storing a password transmitted from the portable system within the base system, with this password later being required within the reset process.

摘要： Initially, a hardware inventory device is provided within the data processing system. UIC that uniquely identifies the data processing system is stored in a non-erasable memory of the hardware inventory device. An encrypted hash generated by combining the UIC and a BIOS hash is stored in the non-erasable memory of the hardware inventory device. In response to a loading of a software program previously installed within a direct access storage device of the data processing system, the following steps are performed: i. the encrypted hash is obtained from the non-erasable memory of the hardware inventory device; ii. the encrypted hash is decrypted; iii. a new hash is generated by using the UIC and a BIOS from the data processing system, and the decrypted hash is compared with the new hash; and iv. the software program loading is allowed to continue when the decrypted hash matches the new hash.

摘要： A method and system for eliminating peripheral device conflicts in a multibus data-processing system which includes a Peripheral Component Interconnect (PCI) plus having multiple slots for interconnecting peripheral devices in an automatically derived configuration and an Industry Standard Architecture (ISA) bus having multiple slots for interconnecting peripheral devices in a user-selected configuration. Each slot included within the ISA bus includes a reset line for temporarily disabling an associated slot in response to an application of electrical power to the data-processing system in order to prevent power transition problems. In response to an existing or potential device conflict brought about by a user-selected configuration, a control signal is selectively applied to the reset line for one or more slots included within the ISA bus, temporarily disabling those slots during normal operation of the data-processing system.
