Abstract
Use of a control storage device coupled with a central processing unit is locked, during the loading process from the unit to the device, to a would-be user of the device until such loading process is complete as indicated by a so-called 'unlock' command received from the central processing unit. An indication of an error or malfunction in the control storage device either during the loading process or thereafter is also provided to the central processing unit.
