ABSTRACT:
A computer network serviced by a maintenance subsystem holds a control processing module (CPM) holding a Data Path Array as interface to a main memory module and I/O Module. A maintenance controller in the CPM has a preloaded Flash Memory unit holding all the necessary operating addresses and data which can be rapidly transferred via a special wide parallel high speed data bus to a data path array unit for subsequent conveyance to a channel microcode block in a main memory module. The operating data include channel microcode data necessary for the I/O Module to communicate with different types of peripheral devices.
