Deviations in the structure of system diskettes > 0.5 Mbyte The system diskette with > 0,5 MByte does not contain redundant system data, i.e. the system data is only available once. That’s the only deviation compared to the system diskette with < 0.5 MByte. A defective system diskette must be replaced by a back–up diskette. The check of the system diskette for mechanical and electrical defects must classify the entire system diskette as faultless. If the message “SYSTEMDISKETTE DEFEKT” (system diskette defective), the back–up diskette must be used or a new system diskette be ordered.

Diskette into the System Memory

The bootstrapping procedure is started automatically after the battery failure signal has become active and the reset signal has been applied either after the supply voltage has been reconnected or by depressing the ZRS key. The battery failure signal becomes active if the battery voltage drops below 2.8 V or if a battery has not been installed. During operation, a low battery voltage is indicated by the message. S 357 Low back–up battery voltage. The battery voltage is cyclically checked every minute. Bootstrapping can also be initiated manually: – Set front panel switch to “BOOT” position and – press ZRS key.

The switch must be set to “RUN” position immediately 

after the system software has been successfully loaded. If this is omitted, each central reset will initiate initial program loading. The switch may be set to “RUN” immediately after the ZRS key has been depressed. It must be reset to “BOOT” if loading has been unsuccessful. Bootstrapping does not modify any user structures. All messages are issued in plaintext during the initial program loading process. In addition to the messages issued, two front panel LEDs on the memory module indicate the current mode and possible faults.
