Abstract: A computing device includes an accessory containing an option ROM, a first processor adapted to boot the computing device and to execute the option ROM, and a second processor adapted to be activated by the first processor to monitor execution of the option ROM by the first processor. The second processor is adapted to restore the first processor to a state prior to execution of the option ROM in response to the first processor becoming hung during execution of the option ROM. A computer program product includes program instructions executable by a processor to monitor execution of the option ROM by a first processor of a computing device, determine whether the first processor has become hung during execution of the option ROM, and restore the first processor to an execution environment that the first processor had prior to execution of the option ROM.

Abstract: A method is performed by a master network device among network devices of a cluster. The master network device receives cluster configuration information including a set of Internet Protocol (IP) addresses and a pool of port blocks associated with the IP addresses. Each port block includes multiple ports, and the pool of the port blocks is to be shared across and used by the network devices for port address translation on network connections with the network devices. The master network device divides the port blocks in the pool into multiple buckets. The master network device first allocates to each network device in the cluster a corresponding one of the buckets, and reserves each bucket that is not allocated for allocation to a potential new network device. When a new network device joins the cluster, the master network device second allocates to the new network device the port blocks from a corresponding one of the reserved buckets.

Abstract: The present disclosure is directed to efficient memory activation at runtime. A memory module (e.g., a memory riser) being added to a device would typically cause the device to enter system management mode (SMM) to activate the memory module. However, activation (e.g., memory module initialization, hardware training and system reconfiguration) in SMM may substantially delay the resumption of normal operations. Consistent with the present disclosure, at least the memory module initialization and hardware training portions of the activation may be performed by an operating system (OS) in the device, allowing normal device operation to continue during the activation. The OS portion of the activation may generate configuration data. In at least one embodiment, the configuration data may be applied for use in SMM. For example, a system management interrupt (SMI) handler may apply the configuration data during a quiescent period (e.g., a period of inactivity) that occurs during SMM.

The method includes acquiring a public network signal evaluation threshold value and a signal threshold adjustment value, the signal threshold adjustment value being for adjusting an evaluation threshold; saving a result of different-frequency measurement by performing the different-frequency measurement on cells; and evaluating the saved result of different-frequency measurement using the acquired public network signal evaluation threshold value and the acquired signal threshold adjustment value. The method and apparatus enable a cluster terminal to timely measure a better adjacent cell and to switch to the cell, thereby making the cluster terminal always reside in a better cell to use voice and data services, ensuring the quality of the services and bringing user experience.

Abstract: A slider design for a hard disk drive (HDD) features an air-bearing surface (ABS) topography with soft bumper pads (SBP) formed proximally to corners of the leading edge and the trailing edge. The bumper pads are formed by a process that combines the use of a first photomask for subtractive etching of the ABS to form pedestals, followed by additive depositions onto the pedestals using a second lift-off photomask. The additive process deposits sequences of Si layers and diamond-like carbon (DLC) layers to produce a soft bumper pad that is energy absorbing and heat conducting, thereby protecting the recording media from surface damage and thermal erasures.
