Diskette Method of Updating Service Devices

      A technique is described whereby read only memory (ROM) service
devices, as used in input/output computer processors to retain code
and pertinent service information, can be readily updated on-line,
through the use of a diskette, in the event updating is required for
any reason.

      A diskette to memory "burn-in" method is described which easily
updates service information any computer processor that utilizes a
separate servicing processor.  The diskette "burn-in" method
eliminates the costly process of replacing many, if not all,
associated service circuit cards during required updating procedures.

      In prior art, ROM circuit cards were used to service
communication processors, or adapters, and required a costly and time
consuming replacement procedure for updating to a new level of
information.  The updating is required to provide compatibility with
the computer processor involved and to provide the required program
coding and information for maintaining the proper level of operation
and service routines.  Because of architectural restraints in the
computer system, hardware levels cannot be changed during operational
mode.  Therefore, the concept concentrates on performing the updating
during routine service and maintenance operations.

      The method used in updating service devices is designed to
utilize electronically erasable programmable read only memory
(EEPROM) devices.  The devices ar...
