PURPOSE:To automate a series of processing by providing firmware referencing a table specifying an operation at fault given in advance when a waiting state of interruption inhibition is detected to attain energizing of an alarm device, collection of faulty information, load of initial program of system and interruption of power and to detect effectively the queuing state of interruption due to fault. CONSTITUTION:The fault processing system detects the queuing state of interruption inhibition and applies recovery processing according to the table specifying the operation at fault given in advance by the operating system. When the queuing state of interruption inhibition is set, a control register A9 is reference at first, and when a bit A is logical 1, the start address of a control table 12 of a main storage device 8 is obtained from a control register B10, a queuing state code given in the progem state word 11 is used as an index to obtain a control entry corresponding to the code. Further, a bit S of a control register A9 is referenced to obtain the operation command from the entry to the present automatic processing mode. |
