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.
!
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.
