    摘要: A data processing system has a microprocessor, a memory system and a plurality of system devices the operation of which is controlled by BIOS routines. The BIOS routines are accessed through protected entry points. When an application program attempts to access one of the routines by using a hard coded instruction for jumping to such entry point, a BIOS signaling routine is executed which provides a signal to an operating system allowing the operating system to control the access without being bypassed.

    摘要: Embodiments of the present invention address deficiencies of the art in respect to trusted platform module (TPM) unification in a trusted computing environment and provide a novel and non-obvious method, system and computer program product for trusted platform module data harmonization. In one embodiment of the invention, a TPM log harmonization method can include designating both a single master TPM for a master node among multiple nodes, and also a multiplicity of subsidiary TPMs for remaining ones of the nodes. The method further can include extending the single master TPM with a measurement representing a rendezvous operation for the nodes.

    摘要: A system and method for remote power control across multiple nodes of a partitioned data processing system. The system includes one or more nodes, each node including a chassis housing a traditional SMP server. The system may be partitioned into two or more SPAR's. Partition management software provides out of band power control to an entire partition, regardless of the number of nodes in the partition. The partition management code installed on each node of the partition is enabled to broadcast a power-on request to each of the nodes in the partition. Thus, when any service processor receives a power-on request, that service processor will resend the power on request to the broadcast group, thereby causing all of the nodes in the SPAR to power up. The broadcast packets may be routed to the other nodes via an out-of-band or private management LAN. Using this implementation, existing network and system management software can reset the system by sending a normal power-on request to any service processor in the SPAR complex thereby minimizing the multi-node architecture's impact.

    摘要: A cache controller structure and method are provided for managing cache access for a computer system. The computer system has a processor having a direction flag and configured to run a repetitive string operation, wherein the string operation is configured to sequentially access a targeted memory block for each repetition depending on the state of the direction flag. A cache controller logic is provided to control a cache embedded in the processor while the processor executes string operations. The cache controller is configured to manipulate the cache lines responsive to the direction flag and to a position of a targeted memory block within a cache line. In some embodiments, the controller logic is also configured to manipulate the cache lines responsive to a repetition parameter value within the string operation.

    摘要: Method and system aspects for securely transferring a computer system are described. A computer system is disabled at a shipping point via an RFID (radio frequency identification) interface and re-enabled at a receiving point via the RFID interface. Disabling the computer system includes selecting a boot password, writing the boot password to storage in the computer system via the RFID interface, and setting a disable bit in the storage via the, RFID interface. Re-enabling the computer system includes entering the boot password via the RFID interface and clearing the disable bit.

    摘要: A security system for computers defines a control zone using radiation, preferably at radio frequency, having a distinctive characteristic, such as a particular frequency. The zone may be established, for example, at a door exit or other limited passage to a secured area. Computer systems are provided with receivers that detect the distinctive characteristic and responsively produce an alarm signal which triggers security logic. The security logic cooperates with the start-up logic of the computer and disables start-up so that the computer becomes inoperative. In a more complex variation, the radiation triggers a device in the computer that in turn sends out a serial number signal. A receiver located near the control zone applies the serial number to a table look up computer that triggers an emergency signal if a match to an authorized list of serial numbers does not occur. The emergency signal activates a transmitter that sends out a radiation signal with a second distinctive characteristic. A second receiver in the computer then responds to the radiation with the second characteristic to trigger the security logic to render the computer inoperative.
