Abstract The RISC System/6000 family of products, typically based on the Microchannel bus architecture, has been expanded to include a new line of products based on the PowerPC microprocessor, the Peripheral Component Interconnect (PCI) bus architecture and the PowerPC Reference Platform Specification (PReP). The AIX Version 4.1 operating system had to be enhanced to support these new systems, and a new software layer had to be incorporated between AIX and the hardware to allow for a transparent implementation of the PowerPC Reference Platform Specification. Support for the Industry Standard Architecture (ISA) bus architecture has been added to allow for the use of the large number of ISA adapters available for personal computers. All these enhancements present new environments and new configuration tasks to system engineers, system administrators and customer engineers. This book is intended to describe this new environment and to assist the support personnel in accomplishing these new tasks.
