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.
Processor Non-maskable Interrupt Test (#82)
This test is a nondestructive test. The test is used to verify that the 80286/386
Processor can detect and respond to non-maskable interrupts. For example, the
processor intentionally causes a BUS TIMEOUT EXCEPTION (BTE) and then
verifies if it vectors to the correct interrupt routine. This is basically a test of the
internal operation of the 80286/386 CPU chip.

ABORT Refer to STBY-SPE Maintenance documentation for a description
of these error codes.
FAIL The computed checksum did not match the ROM checksum. The
system may or may not continue to operate correctly. The system
may fail later when some action requires access to the corrupted
area of the bootstrap ROM.
1. The Processor circuit pack should be replaced. (Note that if
you replace the Processor circuit pack, you need to obtain a
new license file.)
!
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 computed checksum matched the ROM checksum. The
system continues to operate normally.
