The at least two processors include a first processor set as a default boot processor in response to a boot up operation of the multiprocessor computer, and a second processor. The apparatus includes: a baseboard management module for detecting and receiving health information of the processors; a multiplexer coupled to the baseboard management module and respectively to the processors, the multiplexer being operative to switch between the processors; and a processor ID controller coupled to the baseboard management module and respectively to the processors. In response to the health information indicating the first processor has failed, the processor ID controller sets the second processor as the default boot processor and the baseboard management module enables the multiplexer to switch to the second processor.
Abstract:
A method of fabricating a pixel array is provided. A first metal layer is formed over a substrate. The metal layer is patterned to form a plurality of data lines and a plurality of drain patterns adjacent to each data line. The data lines and the drain patterns are separated from each other. An oxide semiconductor layer and a first insulation layer covering the oxide semiconductor layer are formed over the substrate. A second metal layer is formed on the first insulation layer and patterned to form a plurality of scan lines intersected with the data lines and the drain patterns. By using the scan lines as a mask, the oxide semiconductor layer and the first insulation layer are patterned to form a plurality of oxide semiconductor channels located under each scan line. Each oxide semiconductor channel is located between one data line and one drain pattern.

Abstract:
Methods and devices for qualifying a client machine to access a network, based on policies governing required protective measures, such as virus checking and operating system updates, are disclosed. A client machine must pass various checks to qualify for access. A client machine may be redirected to remediation resources that support efforts to bring the client machine into compliance with applicable network access requirements. A policy repository is updated regularly by vendors of protective measures. An administrator establishes user roles that are mapped to policy rule sets retrieved from the policy repository. The policy rule sets govern qualification of client machines for access to the network in accordance with the roles of the users of the machines. An access server is an intermediary between a client machine and the access manager. A client agent runs on the client machine and carries out checks, and reports the results via the access server to the access manager.
