Processor Software Initiated Interrupt Test (#77)
This test is a nondestructive test. The test verifies if the 80286/386 Processor can 
exercise the three types of software-initiated interrupts:
■ Divide by zero
■ Single step
■ One byte interrupt instruction.
Processor ROM Checksum Test (#80)
This test is a nondestructive test. The test computes the checksum of the 
processor’s bootstrap ROM, and it compares this checksum to a predetermined 
value stored within the ROM. A failure of this test indicates corruption of the ROM.

ABORT Refer to STBY-SPE Maintenance documentation for a description of these error 
codes.
FAIL The processor did not detect the software interrupt condition. As a result, the 
processor executed the incorrect interrupt vector. The system may or may not 
continue to operate correctly.
1. Repeat the command at 1-minute intervals a maximum of 5 times.
2. If the test continues to fail, the Processor circuit pack should be replaced.
!
WARNING:
If the TN786B circuit pack [386 systems only] must be replaced, and if 
there is a blank in the Expansion Memory circuit pack slot (that is, in the 
slot immediately to the right of the TN786B circuit pack), remove the 
blank before removing the circuit pack. Otherwise, the circuit pack 
and/or the two connectors that are used to connect the Expansion 
Memory circuit pack (if available) might become damaged.
PASS The processor detected the software interrupt condition, and it executed the 
correct interrupt vector. The system continues to operate correctly.
