Always investigate tests in the order presented in the table below. By clearing
error codes associated with the Packet Interface Private Looparound test for
example, you may also clear errors generated from other tests in the testing
sequence.

Memory Checksum Test (#884)

This test involves sending a message to the Packet Interface to run private
non-destructive memory checksum tests on the firmware text residing in Boot
PROM and FLASH memory. If the test fails during background testing, the Packet
Interface will remain operational until a reset packet-interface is executed. Then
the initialization firmware will fail and will put the packet interface in an
out-of-service state. This test causes the entire I/O-Processor memory to be
tested. The I/O Processor does not support its own Flash Memory Checksum test.
