Abstract: Systems and methods for generating, distributing, and using performance mode BIOS configurations are disclosed. Each performance mode BIOS configuration can be a unique set of BIOS setting values that have been established to optimize a particular performance parameter or set of performance parameters, such as boot speed or operating system installation speed. Based on a given hardware configuration and/or set of performance parameters, one or more performance mode BIOS configurations can be packaged and transferred to a memory of a BMC in the form of one or more configuration payloads. The BIOS Setup Utility can display all configuration payloads, such as listed by the type of performance mode (e.g., “Boot Speed Performance Mode” and “OS Installation Performance Mode”), that are available in the BMC memory and allow a user to overwrite the memory containing the current BIOS configuration with a selected configuration payload.

Accordingly, the porous tantalum has well-distributed interconnecting pores and sintering neck structures resulting in good mechanical properties, and especially good ductility.

Abstract: An apparatus and method controlling cellular automata containing a plurality of cascaded circuit cells having logic units. The cells are interleaved in groups toward supporting multiple directions, for example quad cells in which each cells of the quad is directed in a different directions separated by a fixed angle, such as 90 degrees (i.e., north, east, south, and west). These cells are triggered asynchronously as each cell is stabilized in preparation for receiving the trigger. The cells process data selectively based on the configuration of the cell and in response to receipt of data and trigger (or combined data and trigger) conditions from neighboring cells. The array can be utilized within a wide range of digital logic. As there is no need for distributing a global clock across the array of cells, the size of the array can be extended to any desired dimension.
