3.0 INTRODUCTION
This section of the manual describes the test sections of the memory diagnostic (MDIAG37).
3.1 TEST SECTION 1
Low Memory IDiagnostic Compatability Test
This section tests low memory and diagnostic compatability, reads the syndrome information, and checks
memory configuration.
It
automatically executes when you call up MDIAG37. After completion, this
test section allows the operator to change the configuration of the diagnostic.
Appendix A contains a table that decodes the syndrome codes.
NOTE
I'
This section does NOT allow the Loop on Error option.
Step 11. Low Memory Test -- This step reads the lowest 256K bytes of memory (banks 0 and
1)
to check
for double-bit hardware errors. If there are any double-bit errors in bank
0
or bank
1,
MDIAG37 will not run. This step does NOT have the Loop on Error option. The displayed
failure indication will be a multiple-bit error system halt:
System Halt 6
CPU memo ry parity error - - mu It i - bi terror.
Step 12. Diagnostic Compatability -- This step checks that the system you are testing has the correct
CPU. This step does NOT have the Loop on Error option. If an incorrect CPU is detected, the
following message is displayed:
This diagnostic is only for an HP 3000 Series 37 System.
