Abstract: A hybrid firmware-first/operating-system-first error handling system includes a Basic Input/Output System (BIOS) subsystem coupled to a processing system. The BIOS subsystem begins an initialization process for a computing device and, in response, configures the processing system to perform processing system firmware-first error handling operations and, for any errors that are detected during at least a portion of the initialization process, performs BIOS firmware-first error handling operations.

Abstract: An operating-system-first error handling system includes an operating system subsystem coupled to a BMC device including a shared memory subsystem, and to a reserved memory subsystem storing error handling information that is configured to direct the storage of error information in the shared memory subsystem in the BMC device. The operating system subsystem identifies a first error and generates first error information for the first error. The operating system subsystem then accesses the error handling information and, based on the error handling information, stores the first error information generated for the first error in the shared memory subsystem included in the BMC device. The operating system subsystem then notifies the BMC device of the first error information stored in the shared memory subsystem. The BMC device may then access the first error information in the shared memory subsystem and transmit the first error information to a computing device management system.

Abstract: A BIOS code storage subsystem modification system includes a computing device having BIOS code storage device modification subsystem coupled to a BIOS storage system that includes a BIOS code storage device and a BIOS data storage device. The BIOS code storage device modification subsystem receives a BIOS code storage device modification interrupt and, in response, provides BIOS code storage device modification information in the BIOS data storage device. Subsequent to providing the BIOS code storage device modification information in the BIOS data storage device, the BIOS code storage device modification subsystem causes the computing device to perform a first reboot. During a first initialization of the computing device in response to the first reboot, a BIOS in the computing device identifies the BIOS code storage device modification information in the BIOS data storage device, and uses the BIOS code storage device modification information to modify the BIOS code storage device.

Abstract: Systems, methods, and devices are provided for an engine driven pump gearbox. A engine, such as a gas turbine engine, may drive a primary shaft having a gear. The gear may selectably engage with a gear of a secondary shaft that drives a machine (e.g., pump). By changing whether the gear of the primary shaft is engaged with the gear of the secondary shaft, the gearbox may be switched between an engaged and a neutral (or disengaged) configuration. A power takeoff device (e.g., a generator) may be connected to the primary shaft and may be operated in reverse as a motor to rotate, slow, stop, and/or reverse rotation of the primary shaft. Brakes may be associated with one or more of the primary and secondary shafts. The power takeoff device and one or more of the brakes may be controlled to shift the shafts between engaged and disengaged positions relative to each other.

Abstract: A method of repairing a chain assembly involves aligning bores of inner and outer chain links and inserting a thread end of a pin through the bores. Then, a nut is threadingly engaged with the threads of the pin, the nut is tightened nut on the threads to create an interference fit between the pin and a plate of the outer chain link at the bore of the outer chain link, and the nut is further tightened on the threads until an axial stop blocks further advancement of the nut along the thread end of the pin. Additionally, a kit for repair of a chain assembly system includes a chain link defining a bore, a pin that can form an interference fit with the bore, a nut, and an axial stop that blocks further advancement of the nut along a thread end of the pin when the pin contacts the axial stop.
