A p-type polysilicon resistor formed in the inter-level dielectric layer contains an implanted diode. An installation template is placed at the selected location and support sites on the installation template can be adjusted so that the installation template will support the foundation subassembly in a manner such that the superstructure can be supported in said desired attitude. The method also includes the steps of assigning each of the partitions of the print job to one of a number of raster image processing engines for raster image processing, and, re-aggregating a number of raster image processed partitions from the RIP engines into a raster image processed output file. The packets within a virtual channel may share resources, but the packets within different virtual channels may not share resources. Because the plate member is arranged in the step shape in cross section, fan noise due to disturbed air flow can be restricted.
