5.3 Power-On Self-Test (POST) and ROM-Based Diagnostic (RBD) Failures
Example 5–16 SIMM Wrong Size
Error: SIMM Set 1 (1E,1F,1G,1H), SSR = C14A
SIMM_1E = 16MB SIMM_1F = 16MB SIMM_1G = 64MB ?? SIMM_1H = 16MB
Memory Set 1: 01000000 to 01FFFFFF, 16MB, 32768 good pages, 0 bad pages
ACTION:
Replace SIMM 1G with one of the correct size.
The diagnostics cannot always determine which SIMM caused a failure. If
this occurs and more than one set is present, usually the failing set can be
identified by using the SHOW MEMORY command.
>>>SHOW MEMORY
16 MB RAM, SIMM Set (0A,0B,0C,0D) present
Memory Set 0: 00000000 to 00FFFFFF, 16MB, 32768 good pages, 0 bad pages
16 MB RAM, SIMM Set (1E,1F,1G,1H) present
Memory Set 1: 01000000 to 01FFFFFF, 16MB, 0 good pages, 32768 bad pages
Total of 32MB, 32768 good pages, 32768 bad pages, 112 reserved pages
>>>
ACTION:
Replace SIMM set 1 (1E,1F,1G,1H).
After installing a new set of SIMMs and successfully running power-up tests,
run memory test script A8.
>>>TA8
Note
Script A9 is another memory test script. This script will stop on the
first occurrence of any error. It will also stop on a soft error. If a failure
occurs in A9 and if A9 then runs successfully 10 times and script A8
runs without error the problem is a soft error and does not require
action.
Note
If a memory failure is marked in the bitmap, it will not be erased until
either the system is powered up or the bitmap placing test is run with
