Abstract: A computer implemented method, data processing system, and computer usable program code are provided for implementing a two phase open firmware driver. A computer system probes a device for a dummy image that uses open firmware code in a compiled format. The computer system executes the dummy image. The dummy image has a dummy OPEN method and minimal properties for the device. The dummy OPEN method byte-loads a full image that uses open firmware code in a compiled format and transfers control to an OPEN method contained in the full image. The computer system loads the dummy OPEN method and minimal properties into a memory in the computer system.

Abstract: A method, apparatus, and computer implemented instructions for reporting errors to a plurality of partitions. Responsive to detecting an error log, an error type for the error log is identified. If the error log is identified as a regional error log, an identification of each partition to receive the error log is made. Then, the error log is reported to each partition that has been identified to receive the error log.

Abstract: A method for prioritizing bus errors for a computing system is provided. A subsystem test is executed on a first subsystem from a plurality of subsystems on a bus system, wherein the subsystem test on the bus system is specific to the first bus subsystem. An output is received in response to executing the subsystem test. In response to the output indicating an error on the first subsystem, a severity level is assessed based on the error. For all subsystems from the plurality of subsystems on the bus system, a subsystem test is executed on each remaining subsystem, wherein each subsystem test on the bus system is specific to each remaining subsystem. An output is received in response to executing each subsystem test. In response to the output indicating an error on any of the remaining subsystems, a severity level is assessed based on the error.

Abstract: A method system for reporting error logs in a logical partition computer system is disclosed. Error logs reported for the computer system are stored in an error log partition. An event scan routine is instantiated for each of the logical partitions that make requests to read new error logs in the error log partition. In response to receiving a request from each of the event scan routines, the new error log is retrieved for the respective event scan routines. Once it has been determined that each of the logical partitions have read the new error log, the new error log is marked as ready for deletion in the error log partition.

Abstract: A method, system, and apparatus for managing a failed input/output adapter within a data processing system is provided. In one embodiment, an operating system handler receives an indication that one of a plurality of input/output adapters has failed. The operating system handler consults an error log to determine which input/output adapter has failed. Once the bad input/output adapter has been determined, the operating system handler disables the bad input/output adapter and deallocates any processes bound for the bad input/output adapter without powering down the data processing system. A user is then notified of the bad input/output adapter so that the bad input/output adapter can be replaced. The input/output adapter may be replaced without powering down the data processing system. Once the bad input/output adapter has been replace, the new input/output adapter is enabled.

Abstract: A method of automatically determining errors and appropriate solutions to those errors in a PCI-based computer system is disclosed. The method is easy to maintain and efficient, because it eliminates the need for inefficient and difficult-to-understand program code containing large numbers of cascaded conditional statements.

Abstract: An explosively forged elongated penetrator including a liner having a central section, an intermediate section and a peripheral section; the axial velocity of the sections being approximately equal; the axial thicknesses of the sections decreasing from the central to the peripheral section; the radial velocity increasing from the central to the peripheral section; and the line profile angle decreasing from the central to the peripheral section, to define an explosively driven, inwardly directed, centrally focused force for forging the penetrator from the liner substantially independently of the axial velocities.
