Abstract: The present invention includes processes and resulting structures for producing moisture absorbing desiccant entrained polymers. A polymer is caused to assume a molten state, typically by applying heat and melting the polymer. To achieve certain results in the hardened end product, such as rigidity and durability, the polymer normally acts as a moisture barrier in a solidified state, both before and after melting. A desiccating agent is blended into the polymer so that the desiccating agent is distributed within the polymer. A channeling agent is also blended into the polymer so that it is distributed within the polymer. The blending of the components is preferably done before the polymer is caused to assume a molten state. Together, the polymer, desiccating agent and channeling agent create a blended mixture. The mixture is solidified so that the channeling agent forms passages in the mixture through which moisture is communicable to desiccating agent that is entrained within the mixture.

Abstract: A method and apparatus for configuring a computer system is adapted to allow configuration to occur on the system unit without removing the system unit from its packaging. By so preparing and operating the unit that it can function to a degree as a network client, it is possible to perform steps for configuring "in the package" that violate normal self test expectations. With this abnormal operating environment and operation the system is placed in condition to be removed from the packaging at the user's location with BIOS and program image customized for the user. This approach provides a freshly configured system and yet eliminates unpacking at a configuration center and then repacking for transfer to the user or the need for refresh configuration at the user site as the system unit is set up for normal use.
