Abstract
In a channel control for an information processing system, a service processor (SVP) loads a microprogram of the channel controller at system initialization, and thereafter initiates the microprogram for storing microprograms and configuration information for a plurality of channel units held in the SVP into the specified area of a main storage. Subsequently, the configuration information and microprograms from the main storage are loaded into the channel units under control of the microprogram of the channel controller. Thereby, the microprograms and configuration information are loaded into the channel units by a channel controller equipped with a fast-processing microprocessor and, eventually, a fast loading control and error correction process are accomplished.
